I missed the lecture about air quality. When I guess of air pollution, that’s all outside. So when I l received about the attachion between Heating and Air Conditioning device and the air we breathe inside, I was a bit stunned. Again, I just had no method there were complications when it came to air quality. This assumption was based on the fact that people were always told to stay indoors with the smog was poor when I lived in the city. And air pollution was the stuff coming out of exhaust pipes and factories. It was not something to worry about inside the house. Plus, there was an air filter that I changed each month that actually showed signs of dirt. So I just figured the Heating and Air Conditioning device was cleaning the air. That’s not the case at all. To start, there are loads of things inside our homes that affect the air quality. There are so several synthetics, from carpet to furniture, that are giving off airborne contaminants. Then throw in the pollen, pet dander and all that comes to air quality that isn’t great. And that air filter I was increasing each month was designed to catch the giant stuff so it doesn’t hurt the Heating and Air Conditioning unit. All the other stuff is getting blown around the beach house when the Heating and Air Conditioning device kicks on. So the undoubtedly first thing I did was to replace the Heating and Air Conditioning air filter to a HEPA filter. These HEPA filters remove more than 99 percent of the airborne contaminants that attack my respiratory system. It’s made a tremendous difference as I save my money to go all the way with a whole house whole-house air purifier.
