Indoor Air Pollution and Pregnancy Risk

Pregnancy is a time of growth and many expectant parents use this time to educate themselves. Books, articles, videos, in-person classes — pregnancy resources abound in our modern world. And one of the most common pregnancy safety questions expectant parents ask is: “What should I avoid when I’m expecting?” Smoking, alcohol, and certain medications usually top the list. Other culprits include soft cheeses, deli meats, and fish with high mercury levels. But what about air pollution?

According to the American Lung Association, common outdoor air pollutants include ozone, particulate matter, nitrogen dioxide, sulfur dioxide and carbon monoxide. Toxic air pollutants can come from burning fuels, vehicle exhaust, building emissions and other sources. However, most people spend 90% of their time indoors.

With recent research showing that air pollution can significantly impact mothers and babies, pregnancy is a good time to consider your home’s heating, ventilating and air-conditioning (HVAC) system. Humidifiers and air purifiers can help with indoor air quality, but if the source of your air, your HVAC system, isn’t clean, those additional measures won’t matter.

An informed decision on the heating and cooling components you use can affect your air quality. Depending on the temperature where you live, your home might require a furnace-air conditioner combination to heat and cool your home. A heat pump can be a great option for more moderate climates. Because heat pumps don’t use combustion, there is no risk of carbon monoxide filling the air of your home.

No matter how you choose to heat and cool your home, one thing is certain: clean air is best for everyone, and especially for pregnant mothers and newborns.


Studies have found links to adverse health outcomes because of poor air quality or air pollution. Some affect women before or during pregnancy, while others appear in babies or even older children.

Low birth weight

After a typical, healthy pregnancy, a full-term baby usually weighs between six and nine pounds. Low birth weight is defined as less than 2,500 grams, or five pounds, eight ounces. The Centers for Disease Control reports that about 8% of babies in the United States are born with low birth weight.

Multiple studies have observed the effects of air pollution on birth weight. One study conducted in Los Angeles investigated obstetric records of births by non-smoking women. Mothers living in more polluted areas gave birth to babies who weighed, on average, 314 grams, or 0.69 pounds, less than infants who were born to women residing in less polluted areas.

Another study from China observed women who were pregnant during the 2008 Beijing Olympics, a two-month period when the city was required to lower emissions and improve air quality. The study revealed mothers who were eight months pregnant during the Olympics gave birth to babies who were 0.8 ounces heavier, in contrast to women who delivered during the same calendar months in previous years.

Preterm birth

Babies born before the 37th week of gestation are considered preterm and are at risk for neurological disorders and permanent physical disabilities, as well as for breathing difficulties, cardiac problems, an inability to maintain body temperature, an immature digestive system and retinopathy. While premature birth can happen to anyone for many reasons, air pollution is one possible reason you should try to avoid.

Several studies have found links between air pollution and preterm birth. One by the Stockholm Environment Institute (SEI) at the University of York revealed that “in 2010, about 2.7 million preterm births globally — or 18% of all preterm births — were associated with outdoor exposure to fine particulate matter.” A Swedish study published in 2013 showed a correlation between first-trimester ozone exposure and the incidence of preterm birth, while a National Institutes of Health study suggested air pollution exposure during a second pregnancy may increase the chances of preterm birth.

Autism spectrum disorder

According to a 2014 study from the Harvard School of Public Health, expectant mothers who are exposed to high levels of fine particulate matter during the third trimester could have twice the risk of having a child with autism spectrum disorder (ASD) than pregnant women living in areas with low particulate matter. The researchers did compile data during all three trimesters of pregnancy, but they noted that the “only statistically significant association” between fine particulate matter and autism spectrum disorder occurred during the third trimester.

The study followed women from 14 states in all regions of the continental United States. It also considered factors such as population density, elevation and distance to freeways and other particulate sources, like power-generating utilities and waste combustors.


For pregnant women who have asthma, as long as it is well controlled, the condition poses no significant risk to the mother or the unborn baby. Uncontrolled asthma during pregnancy, however, can lead to high blood pressure, pre-eclampsia or premature delivery. No matter how well controlled a person’s asthma, air pollution can worsen asthma symptoms.

In addition, recent research has shown air pollution exposure during pregnancy may increase the likelihood of the baby developing asthma later in life. A 2016 study looked at the role of air pollution from traffic sources in urban areas. Researchers discovered that “children whose mothers lived close to highways during pregnancy had a 25% increased relative risk of developing asthma before the age of five.”

Fertility challenges and miscarriage

Multiple studies, including a 2018 systematic review of literature, have suggested that “air pollution could represent a matter of concern for female infertility.” In fact, one study found that fertility rates in northern California increased when eight plants burning coal and oil closed down, reducing the levels of fine particulate matter and nitrogen oxide.

Scientists have also devoted much effort to studying the effects of air quality on miscarriage, often called spontaneous pregnancy loss in the medical community. They have concluded that “short-term exposure to elevated levels of air pollutants was associated with higher risk for spontaneous pregnancy loss.”

Other risks and takeaways

When it comes to air pollution and pregnancy safety, researchers have also found links to increases in gestational diabetes in expectant mothershigh blood pressure in children and delayed psychomotor development. However, it is important to note that most studies so far have established only correlations between air pollution and disease, rather than a direct cause and effect.

While the research is compelling, remember, in some cases, scientists have not determined which time period — week, month or trimester — is most susceptible to the dangers of air pollution. In addition, most studies have focused on outdoor air pollution, so more research is necessary to understand the effects of poor indoor air quality on pregnancy.


According to the EPA, outdoor air pollution can affect human health, harm the environment and cause property damage. Interestingly, the EPA has reported that “the air within homes and other buildings can be more seriously polluted than the outdoor air in even the largest and most industrialized cities.”

How is this possible? One reason is inadequate ventilation. Scientists who have studied sick building syndrome found that designers in the 1970s made buildings more airtight in an effort to improve energy efficiency. The reduced ventilation negatively impacted the health of building occupants. More recent standards from the American Society of Heating, Refrigeration and Air-Conditioning Engineers require an increased outdoor airflow rate.

What’s the application to homes, where we spend the majority of our time? Most residential structures are designed to minimize the amount of outdoor air that can “leak” into and out of the home. When not enough outdoor air enters a residence, pollutants can build up, according to the EPA’s resource, “The Inside Story: A Guide to Indoor Air Quality.”

Outdoor air enters and exits a house by three methods: infiltration, natural ventilation and mechanical ventilation. Infiltration means that outdoor air flows into the house through openings like joints, around windows and doors, and cracks in walls, floors and ceilings. Natural ventilation is when air moves through opened windows and doors.

An example of mechanical ventilation is a fan that intermittently vents to the outdoors, removing air from one room, such as a bathroom or kitchen. A larger air handling system uses fans and ductwork to regularly extract indoor air and deliver filtered outdoor air throughout the house.

When infiltration, natural ventilation or mechanical ventilation are not adequate, indoor air pollution levels can rise. Most immediate effects of poor indoor quality are similar to the common cold or other respiratory viruses. Therefore, it can be difficult to know if the symptoms are related to air quality or minor sickness. If you experience troublesome respiratory symptoms, try to note the time and place they occur. If they go away or decrease when you’re away from home and return when there, this could mean poor indoor air quality is to blame.

HVAC maintenance and indoor air quality

When it comes to pregnancy safety, it’s important to investigate the air quality in your home even if you’re not experiencing nagging respiratory symptoms. Some health effects show up only after years of repeated exposure to poor air quality, and these can be as serious as cardiovascular disease or cancer. Here are some actionable steps to check your home’s air quality:

Find sources of air pollution

Check for signs of ventilation problems. According to the EPA, these include “moisture condensation on windows or walls, smelly or stuffy air, dirty central heating and air-cooling equipment and areas where books, shoes or other items become moldy.” Other possibilities are a gas stove, certain building materials and synthetic or treated upholstery.

You might also consider testing your home for radon, a colorless, odorless, radioactive gas. Inexpensive testing devices are available, or you can hire a professional to conduct testing. Local and state health departments often have consultants who can help with identifying and solving problems related to indoor air quality.

Improve ventilation

You can reduce the concentration of indoor air pollution by increasing how much outdoor air is entering your home. Weather permitting, the simplest ways to improve ventilation are to open windows and doors, run window or attic fans and operate a window air conditioner with the vent control open. Another option is using bathroom or kitchen fans that exhaust outdoors, eliminating toxins from the room and boosting the outdoor air ventilation rate.

If you are doing a temporary activity that can release pollutants into your home, it’s essential to have good ventilation. Examples are painting, paint stripping, heating with kerosene, welding or sanding. When possible, move those activities outdoors.

Replace or add equipment

If you have a traditional HVAC system or furnace, the EPA recommends changing the filter every 60-90 days. Make sure to buy the correct size; it should fit snugly so air does not leak around the filter.

You might also consider adding a portable air cleaner to your home. This is a separate unit that filters gases or particles, even the fine matter that is considered most harmful. There are different types of air cleaners, and effectiveness varies widely. Most air cleaners filter either particulate matter or gases, so if you’re looking to reduce both, you will probably have to purchase two units.

Another possibility is to switch to a heat pump, a decision that depends on climate, budget and personal preference. The average cost of a heat pump ranges from $700 for a ductless mini-split system to $13,000 for a geothermal heat pump system. Regarding air quality, heat pumps do not use combustion and, therefore, do not produce harmful emissions.


Pregnancy is usually a joyous time for expectant parents as they anticipate a new baby. But it can also feel overwhelming when digesting new information, budgeting for baby expenses and preparing your home for your baby’s arrival.

By maintaining your HVAC system, you can find reassurance by avoiding costly breakdowns and repairs. The last thing you want during an already uncomfortable pregnancy is a home that’s too hot or too cold. Having a well-kept HVAC system ensures the air you breathe is clean, giving your baby a greater chance of protection from the risks of poor air quality.


Many expectant mothers might spend time carefully inspecting ingredient lists and conducting online research to guarantee these things are safe for your growing baby.

Breathing clean air, thanks to a maintained HVAC system, is just as essential as the healthy food and hydrating beverages you put into your body during pregnancy. The source of your home’s air is your HVAC system, and it’s important to understand its condition, both on the interior and the exterior, during pregnancy and when welcoming your new baby into the home.

5 Fast Fall Fixup Ideas for Your Home

5 Fast Fall Fixup Ideas for Your Home

Sweep in a new season with these fast fall fixes for your home. With details on the tasks you should tackle this fall, you’ll know just what to do to welcome in a wonderful autumn.

  1. Swap out your air vent covers or grilles with a fashionable fall themed cover.
    While you routinely clean out your air filters, have you thought about swapping out your dusty old vent cover? Get rid of the grilles or return covers that are getting in the way of your signature style. Our popular Leaves design adds classic Charleston charm to any room. The delicate details of our laser-cut natural wood covers helps bring in the sweet feeling of fall throughout your home decor.
  2. Seal off drafts as you get ready for the fall season.
    The days of leaving the windows open and grabbing extra fans to cool down are almost over. While you prepare for the scent of pumpkin spice lattes and ready all your cozy fall sweaters, take some time to find the drafty spots by your windows and doors. Add some weather stripping to help create a better seal so your fall electric bill doesn’t come as a surprise this time around. If you have ceiling fans, look for the switch on the side of the fan’s unit and flip your fans so they turn in a clockwise direction. This will move warm air from the ceiling down to the floor.
  3. Give your exterior and interior lights a little love.
    As we fall back and Daylight Saving Time ends, you’ll see a little less sunlight. Make up the difference by adding exterior lighting. Line your walkways and garden paths with warm-glow all weather lights or hang up string lights for a cozy fall feel. And don’t forget about your interior lights, too. Replace old light bulbs or swap out the bright cold white bulbs for ones with a warmer fall glow.
  4. Update the entryway.
    Get ready for muddy boots and rain jackets instead of flip flops and tennis shoes being tossed off right when the kids come through the door. Now’s a good time to add an entryway rug that can handle some damage. Find a rubber or PVC backed rug that’s easy to wipe down. Your floors and your chores list will appreciate it.
  5. Add autumn accents and decorate!
    With the cleaning and organizing out of the way, get to the fun part of fall fixups –– the decorating part! Create a bowl of decorative gourds, pumpkins and acorns for a fall harvest feel. Add a seasonal fall wreath on your door to welcome your family and friends. Now’s the time to have fun with seasonal pillow covers, stylized centerpieces for your dining table, and more!

Air Filter: Major Consequences of Not Changing It

Air Filter: Major Consequences of Not Changing It

If you are like most people, you aren’t thinking about your HVAC system until it stops functioning the way it should. Do you know one of the biggest sources of a system complication or failure? A clogged air filter. Read on to learn more about how air filters function in your HVAC system and what can happen when they aren’t changed on a regular schedule.




Air filters are generally made of spun fiberglass or pleated paper and surrounded by a cardboard frame. They are inserted into a specific place in the HVAC systems and act as a barrier to prevent contaminants and other particles from circulating in the air, or from reaching sensitive parts of the system. Some of the common things that filters block are dust, pollen, lint, mold, hair, animal fur, bacteria, and more.




Depending on the type of air filter you are using, you will need to follow different schedules to ensure that the filter is always functioning for optimal performance. Most manufacturers recommend that basic filters are changed every 30 to 60 days, but there are other circumstances that could affect that schedule.


  • A filter in a regular home with no pets should be changed every 90 days
  • If your home has a single pet, the filter should be changed every 60 days
  • For multiple pets, or if anyone in your home suffers from allergies, you’ll want to change the filter anywhere between 20 to 45 days
  • People in single-occupant homes with no pets, or those who own vacation homes that don’t get much use, can usually wait for 6 to 12 months before changing their filter




When air filters are not consistently changed, they get clogged by the buildup of particles and contaminants that stick to the filter.  While the filter is designed to accommodate these minuscule items, the buildup creates an almost impenetrable barrier so that the air cannot completely flow through, which can ultimately cause multiple problems for the entire HVAC system.


 Higher Energy Bills


When the filter becomes clogged, air cannot easily flow through the system. This causes the whole system to have to work harder to distribute heat or air where it is needed, which increases your utility bills since the air is running for longer.


Poor Temperature Regulation 


Since clogged air filters make the system strain to create airflow, warm or cool air cannot adequately go where it is needed. This means that some rooms could be too cold during the winter or too hot in the summer.


Health Concerns 


If the air filter is clogged and cannot trap contaminants as it did before, those things can end up back in the air that everyone in your home is breathing. Immediate issues could include headaches, itchy eyes or throat, and dizziness. If the air filters are not changed and the issues continue, the long-term effects could be respiratory diseases, heart disease, or cancer.


Furnace Failures


As the system is working harder to get around clogged air filters, it can cause the entire system to overwork and eventually break. If this happens, you’ll need to replace the entire system, which can cost anywhere from $4,000 to $12,000. Air filters usually cost less than $40, so they are easy to replace frequently compared to replacing the entire system.


Clamped-Up Coils 


Evaporative coils, which help remove heat from the air to keep your home cool, can freeze up if they are overworked. With a clogged air filter, the air won’t flow over the coils correctly, which makes them stop working and leads to total system failure. Again, the price to fix this issue is greater than simply purchasing a new air filter every few months. Protect your HVAC system and your wallet by replacing the air filters on a regular schedule.




If you haven’t changed the air filters in your home lately, your next step should be to figure out which filters you need and replace them as soon as possible. If you find that the old filters look like nothing, not even air, could ever pass through them, it’s time to contact an HVAC professional. They can visit your house to inspect the system and resolve any issues caused by the clogged filters, thus preventing further problems in the future.

How Does an HVAC System Work?

How Does an HVAC System Work?


HVAC stands for heating, ventilation, air conditioning system. It provides thermal comfort and improvement in air quality. This system is one of the most important parts of a building, it includes the exchange of air to the outside and supplies the circulation within the building. Supply ventilation systems allow for better control of the air that enters the house. It removes pollen, dust and dehumidifies to provide humidity control.


Supply vents blow air outwards into a room. They are usually smaller and have slats behind the vent covers. Air returns suck the air out of the room into your ducts, and back into the furnace. 


If your furnace is in the basement, more than likely this is where you will find the removable air filter that keeps your air clean. If you don’t have a basement, then most likely your furnace is in the attic. It would be very inconvenient to go to switch the filter in the attic, that’s why these homes will filter the air in the air returns located on the walls and ceilings. This makes the filters easier to access and replace!


Typically air filters for HVAC systems should be changed at least twice a year. A good trick to keep on track is to replace the filters when you switch your clocks for daylight savings time. Change the clocks, change the filters. That way you never forget! 

If your home is more prone to dust, or pollutants, than you may want to change it more than twice a year. 



The most important part of a HVAC system is the thermostat. The thermostat triggers the entire system to start cooling or heating.  It is normally centrally located in your home and programmed based on your preferences. 

Furnace &  Heat Exchanger

The furnace heats the air that moves through the system with natural gas. Within the furnace is a heat exchanger, which is responsible for heating up the air to the right temperature. You’ll typically find the furnace in the attic, basement, or a specially designed closet space.

Air Conditioner

The air conditioner cools the air and is found outside of the building. It uses electricity and coolant liquid to reduce the temperature of the air, while sending hot air outside and cold air inside.


Ducts are a very important part of the HVAC system! They help move air efficiently throughout the home. It is a channel of connected tubes that are built behind the walls. Ducts are responsible for delivering and balancing the air flow through the rooms of your house. Ducts connect to the air vents that you see on your floors, walls and ceilings.

Air Vents

Vents are the final part of this system. There are two types of vents – supply vents and air returns:

Supply vents, supply air to the room.

Air returns remove the air from the room and suck it back into the system to be recycled and reconditioned by the furnace.

Troubleshooting Guide for Air Conditioning

Troubleshooting Guide for Air Conditioning

Air conditioners are essential to keeping your home cool and comfortable, especially in the summer. When your AC breaks down, waiting for a professional to come to your home and fix it can take days or weeks, depending on scheduling and availability. Often, simply popping open a window or running a fan isn’t enough on a particularly hot summer day. The good news is that there a surprising number of instances in which you can diagnose and repair a broken AC on your own. This article reviews troubleshooting tips and highlights a few common issues and solutions so you can get your AC back up and running.


  • Make sure the thermostat is set properly. Sometimes fixing your air conditioner is as simple as learning to set the thermostat properly. If set incorrectly, your air conditioner may not work the way you want it to. You might have your thermostat set to heat instead of air conditioning. If this happens, you’ll likely have hot air coming out of your air conditioning vents. It’s easy to forget to make the switch when the seasons change. Double-check this before you assume that your AC unit is broken.
  • Change the thermostat batteries. Have you checked the batteries in your thermostat lately? If you haven’t changed the batteries in a long time, you might be dealing with a dead battery. Without functioning batteries, the thermostat cannot communicate with the air conditioning unit.
  • Replace the air filter. If the filter gets too dirty, the air cannot flow properly. As a result, your air conditioner won’t work as well or maybe at all. Modern air conditioners in particular are extremely sensitive to dirty air filters. If you can’t remember the last time you changed the filters, it’s time to change them.
  • Check your circuit breaker. The next thing you can try troubleshooting is checking your circuit breaker. If the circuit breaker connected to the air conditioner has been tripped, you’ll need to reset it.
  • Check the air vents. Make sure that all of your air ducts and vents are clear. If they get clogged by dust or dirt, the air can’t flow properly; simply cleaning your air vents could be the answer to your problems. There may also be issues within the air ducts that you can’t see. Things like mold or vermin infestation can prevent your AC from working properly.


While there are plenty of things you can do on your own troubleshooting and combatting common problems with your air conditioner, there are several instances where you need to contact a professional.

  • Strange Noises Coming From Your AC: Is your air conditioner making loud banging, clanging, or other unfamiliar noises? If these sounds are coming from your air conditioner or vents, you likely have a serious problem. This is not something you can fix on your own, but an HVAC professional will understand the issue and find a solution.
  • Issues with the Outdoor Unit: If your outdoor air conditioner unit is the problem, you should not try to fix this yourself. While changing your air filters and replacing batteries are perfectly fine for you to do on your own, fixing more complicated issues may void your warranty. For true maintenance issues, it’s best to contact a professional.
  • Improperly Installed AC: If you’ve noticed that your air conditioner was not installed properly, you should call a professional to reinstall or fix it.

Actually, Closing Air Vents Does Not Save You Money

Actually, Closing Air Vents Does Not Save You Money

Just like turning a light off in an unused room, closing an air vent is one of the ways many people try to save money and energy. It just seems like common sense. After all, why should an empty room be air conditioned?

Well, the truth is, that empty room needs to get air flow because closing the vents is doing more harm than good. Keep reading to see how we break down this common misconception and share why letting your air vent flow freely is better for your home.

Gemstone - Vent Cover - Ceiling Close Up, Decorative Air Vent, Custom Air Vent Cover, Stellar Air, Charleston, SC

Your air vents don’t talk to your HVAC system. No matter how you adjust the cover to increase or decrease the air flow into a room, you’re getting the same amount of air and the same amount of pressure. When your air vents are closed, that air is still pushing to get through and into that room, but it doesn’t have anywhere to go, so instead it builds up pressure and is pushed elsewhere.

Depending on the blower system you use, you’ll either end up with a higher electricity bill or a high-dollar repair bill:

Permanent split capacity (PSC) blowers can’t overcome extra pressure from closed vents. It will keep spinning and trying to work, but as more pressure builds, less air flow is circulated through your home. Low airflow means your air conditioner’s evaporator coil is going to get too cold and it may even freeze over. If this happens too much, you risk your outdoor unit’s compressor giving up completely… and having to buy a new one to replace it.

Electronically commutated motor (ESC) blowers, however, adjust speed based on different conditions. So unlike the PSC, it can overcome extra pressure from closed vents. While you have a lower risk of damaging your compressor and evaporator coils, your ESC is going to work harder to adjust the pressure –– meaning it’s going to ramp up on energy to get its job done. Keep in mind that leaky air ducts are quite common in homes. As pressure increases, air will push through the leaks, meaning less air is working harder to go where it doesn’t belong.

Both systems run the added risk of increasing condensation, which in turn, increases the likeliness of mold and mildew building up in your ducts. No matter your blower system, closing your air vents causes problems that hurt your wallet more than help your home.

So what should you do instead?

Rather than trying to redirect air, one solution is to program your thermostat to turn on during certain times of day. Rather than running constantly and running up bills, you’ll use your AC system more efficiently and keep your airflow going safely.

Balance is key for lower energy bills, a healthier HVAC system and more efficient airflow. Closing vents contributes to many issues with your HVAC system –– but vents themselves can also be an issue with your airflow. Older vents are dusty, ugly, and may not be tested to ensure maximum airflow. If your vents aren’t allowing all of the air to get through, even if they’re open, you’re likely to run into similar issues as keeping them closed.

Make a simple switch by using Stellar Air’s vent covers that are lab-tested for maximum airflow and handcrafted here in the USA. Our grilles and ventilator covers are quality tested to improve your airflow and look stylish in your space.
