How Does Your Fireplace Affect Indoor Air Quality?

Fireplaces, especially wood-burning fireplaces, are a common and excellent addition to your home for their functional and aesthetic charm. They are not only good-looking but also a reliable source of warmth, especially during the cold seasons. You can choose from traditional rustic styles and modern options, depending on your preference. However, regardless of your choice, all fireplaces affect indoor air quality. Even though modern fireplace designs are quite safe, you should use them according to the manufacturer’s directions to enjoy the safety benefits.

Why Fireplaces Are Dangerous for Your Indoor Air

All fireplaces, be it gas or wood stoves, produce significant indoor air pollutants. According to the Environmental Protection Agency, wood fireplaces are overly dangerous as they release air contaminants and carcinogens, leading to breathing problems. That said, below are ways in which fireplaces affect the quality of indoor air.

1. Emit Carbon Monoxide

Carbon monoxide is an odorless and colorless gas that hinders the body’s ability to acquire oxygen. Small amounts of carbon monoxide in your indoor air can lead to headaches, dizziness, fatigue, and disorientation. On the higher spectrum, indoor air saturated with carbon monoxide can lead to unconsciousness and even death. Therefore, if you have and frequently use fireplaces, ensure that you monitor the amount of carbon monoxide in your indoor air, especially if you have children or family members of advanced age.

2. A Source of Nitrogen Dioxide

Nitrogen dioxide is another dangerous component of air that can lead to sore throats, itchy eyes, and nose irritations. In addition, inhaling high amounts of nitrogen dioxide causes shortness of breath, while extended exposure can predispose one to lung diseases, such as emphysema. Nitrogen dioxide is specifically harmful if you previously have asthma or any other respiratory condition. Fortunately, unlike carbon monoxide, nitrogen dioxide has an odor and can be easily detected.

3. Particles

Another deleterious effect of fireplaces is the emission of particles into the air. Incomplete combustion of wood or gas produces tiny particles that can easily be inhaled and cause damage to the lungs. Inhaling particles to the lungs can cause several respiratory problems, including difficulty in breathing, and potentially aggravates pre-existing conditions, such as bronchitis, allergies, and asthma. Long-term exposure leads to irreversible lung damage, and some particles can lead to lung cancer.

4. Negative Pressure

Lighting your fireplace also develops negative air pressure, which consequently affects the quality of your indoor air. Fire in the chimney flue creates negative pressure, which sucks up indoor air into the chimney for continuous combustion. While this is the mechanics behind how fireplaces improve indoor warmth, an unintended consequence of negative pressure is pulling high radon levels into the house. Radon levels, which is a dangerous radioactive gas, often double any time you light the fireplace.

Maintaining Indoor Air Quality When Using a Fireplace

If you must use a fireplace, especially for warmth during cold seasons, consider the following precautions to maintain good indoor air quality.

• Use a Vented Fireplace

It is prudent to install a fireplace vent that directs fumes from your fireplace outside. Essentially, this means that your fireplace should vent adequately. Minor issues in the chimney or flue pipe can interfere with the removal of harmful gases, increasing their concentrations in indoor air.

The best way of achieving this is to ensure that you purchase a vented fireplace. Note that unvented fireplaces exist. Therefore, ensure that your purchase is specifically marked as “Vented fireplace.” Unvented fireplaces are only safe when used correctly.

• Install Carbon Monoxide Detectors

Installing carbon monoxide detectors is probably the best way of monitoring the level of carbon monoxide in your indoor air. Carbon monoxide can be released anytime there is improper combustion. While this production is not harmful in itself, health dangers arise when there is poor ventilation.

Since carbon monoxide is colorless and odorless, you can only monitor its levels using carbon monoxide detectors. To maximize the safety of your indoor air, hire professionals to install these detectors in your home.

• Use the Right Fuel

Using the correct fuel is another way of minimizing fireplace dangers. For instance, if you have a wood-burning fireplace, use hardwoods, such as oak, beech, maple, and ash. Dried woods burn cleaners and release less smoke. Avoid soft burning woods, such as pine or fir. Similarly, avoid using painted, treated, or wet wood.

• Use Filters When Burning Less Clean Fuel

If your only option is burning less clean wood, you can still improve your indoor air quality by installing HEPA filters, which significantly reduce particle pollution.

Conclusion

While it may be surprising to many homeowners, fireplaces have a significant effect on indoor air quality. Therefore, regular evaluation of your indoor air quality is important to ensure that you live and breathe clean air. Use the tips mentioned above to improve indoor air quality and reduce the risk of developing dangerous respiratory problems.
