I must have missed the class on fantastic air quality. Perhaps that has something to do with the fact that I’ve lived in a wonderful, rural section all our life. The people I was with and I have great, pollution free air all around us. There aren’t any factories belching yuck into the air or any of that. However, this region is also a arena that has to deal with a enjoyable deal of heat and humidity. That makes for a lot of Heating, Ventilation, and A/C cooling. And when the Heating, Ventilation, and A/C component is on, the house is sealed up tight. The people I was with and I keep our condo sealed tight in order to maximize the efficiency of our Heating, Ventilation, and A/C equipment. Keeping the Heating, Ventilation, and A/C treated air inside and the heat out is the way to keep the Heating, Ventilation, and A/C cooling cost down. But what I didn’t know until rather recently was that a sealed up house is prone to indoor air pollution. There are plenty of airborne contaminants in our condo even though all of us live where all of us do. Between the pets and all the synthetic chemicals being released from carpet and furniture, our air quality wasn’t good. Once I l gained all about this, I also l gained that there is a straight-forward way to official the air quality or at least make it a whole bunch better. All I had to do was change our air filter to a HEPA filter. The HEPA filters cost more than the cheap air filters I’ve been using for years. But they remove more than 99 percent of all the airborne contaminants inside the house. Once all of us made the decision to go to the HEPA filter, the air in our condo was noticeably cleaner for sure.
