For me, I had no idea that inside air could really be all that unhealthy. This is due to the misunderstanding that air pollution is an outside thing alone. But that’s what I thought. My idea of air pollution was vehicle and factory exhaust that made the air smell bad and noxious to breathe. That was air pollution and not inside an HVAC maintained house. So I was really surprised to learn that the EPA considers indoor air quality to be on the list of worst health hazards we all come in contact with. But there are so many things in our homes that give off chemicals. From the carpet to furniture to other household items, our air inside our homes has a lot of stuff going on. Then you have the HVAC heating and cooling equipment recycling all of that as well. And then you throw in all the allergens and other airborne contaminants and it can create really poor indoor air quality. Well there is one quick and easy HVAC fix for this. All we had to do was upgrade our HVAC air filter. We got rid of the cheap air filters and replaced them with HEPA air filters. The HEPA air filter traps and removes over 99 percent of all airborne contaminants. It costs a bit more but the difference it makes is just so worth it. Plus, our health is worth a few more dollars spent for a HEPA air filter. All I know is that once we put in the HEPA air filter, our indoor air quality went from poor to great. And that’s what we were looking for.
