As a homeowner, you want your indoor air to be clean and healthy for your family. Unfortunately, indoor air pollution is all too common and can cause allergies, asthma, and other respiratory problems. The good news is that several furnace upgrades can help improve indoor air quality, including each of the following:

Air Cleaners

Air cleaners are a popular furnace upgrade that can help remove pollutants and allergens from the air. They trap dust, pollen, and pet dander in a filter. Different air cleaners, including mechanical, electrostatic, and HEPA filters, are available. Automatic filters are the most common type and can remove up to 95% of airborne particles. Electrostatic filters use an electrical charge to attract and trap particles, while HEPA filters can remove up to 99.97% of particles.


Humidifiers are another popular furnace upgrade that can help improve indoor air quality. They add moisture to the air, which can help alleviate dry skin, scratchy throats, and other respiratory problems. Different types of humidifiers are available, including evaporative, ultrasonic, and steam. Evaporative humidifiers use a fan to blow air through a wet wick or filter, while ultrasonic humidifiers use high-frequency vibrations to create a fine mist. On the other hand, steam humidifiers boil water to release steam into the air.

UV Lights

UV lights are an effective furnace upgrade that can help kill germs and bacteria in the air. They work by emitting a particular type of light that can destroy the DNA of microorganisms, preventing them from reproducing. UV lights are often installed in the air ducts of your furnace and can help improve indoor air quality by reducing the number of harmful particles in the air.

Carbon Monoxide Detectors

Carbon monoxide (CO) is a colorless, odorless gas that can be deadly if inhaled in large quantities. Furnaces that run on gas or oil can produce CO, which can leak into your home if the furnace is not properly maintained or vented. Installing carbon monoxide detectors in your home is essential to protect your family from CO poisoning. These devices can detect the presence of CO in the air and sound an alarm to alert you to the danger.

Energy Recovery Ventilators

Finally, energy recovery ventilators (ERVs) are furnace upgrades that can help improve indoor air quality by exchanging stale indoor air with fresh outdoor air. ERVs use heat from the outgoing air to warm the incoming air, reducing energy costs while improving indoor air quality. They also help remove pollutants from the air, such as volatile organic compounds (VOCs) and carbon dioxide.
