Being proactive about improving indoor air quality

Because of the threat of the coronavirus, I got concerned about the cleanliness and health of my home.

I became convinced that I needed to be more proactive. I started with the filters of the furnace and air conditioner. I know that a lot of contaminants are introduced into the breathing air by way of the heating and cooling system. I thought I could minimize air pollution by purchasing higher quality air filters and replacing them more often. I found that the more expensive air filters provide a higher MERV rating. This means that they feature much smaller holes and trap more dust and other particles. What I didn’t realize is that these tiny holes quickly become clogged with debris. Once the filter is dirty, air can no longer pass through it. This creates a big problem for the furnace and air conditioner. Unless I wanted to change filters every week, I needed to try a different approach. I did some research and learned that the air filter in the system is designed to protect the furnace and air conditioner from contamination. The filter helps to keep the equipment clean and running more efficiently. It doesn’t do much for indoor air quality. As I read further, I learned about the different air quality products on the market. There are air cleaners, air purifiers, germicidal UV lights, ventilators, humidifiers and dehumidifiers. The various air quality options incorporate into the central heating and cooling system to treat the air as it passes through. I chose an in-duct air purifier that uses positive and negative ions to disrupt the DNA of pathogens and to cause particles to clump together and fall out of the air. The system is silent, requires no maintenance and has been proven effective against certain strains of the coronavirus.
