Each day it seems as though I find yet something else that proves to be, once again, that I really don’t know anything.
Well, that may be overstating it a bit.
But it’s pretty close. It took a pandemic to introduce me to indoor air quality. One would think that I should kind of have a clue about indoor air quality as a grown person. But I didn’t. I thought the air conditioning was good air. And air pollution was for outside right? That is not the case at all. In fact, you can live in a rural area with the cleanest air and still have bad indoor air quality. And while the HVAC equipment does play a part with indoor air quality, air conditioning isn’t cleaning the air. So why is there dust and dirt on the HVAC air filter when I change it each month? That was my main reason for thinking that the HVAC unit was cleaning the air. It wasn’t. The cheap paper air filters I was using were actually there to protect the health of the HVAC unit and not my respiratory health. That was a stunner. Those cheap paper air filter aren’t removing the airborne contaminants that attack our respiratory system. For that, I changed to the HEPA filter. This type of HVAC air filter actually removes more than 99 percent of the airborne contaminants that hurt us and drag down our immune response. I’m just thrilled that all it took was changing an air filter to produce good indoor air quality inside my home.
