I must have missed the class on great indoor air conditions. Perhaps that has something to do with the fact that I’ve lived in a attractive, rural area all our life. The two of us 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 site that has to deal with a great 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 device is on, the home is sealed up tight. The two of us keep our home sealed slender 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 assume until rather recently was that a sealed up home is prone to indoor air pollution. There are plenty of airborne contaminants in our home even though both of us live where both of us do. Between the pets and all the synthetic chemicals being released from carpet and furniture, our indoor air conditions wasn’t good. Once I l received all about this, I also l received that there is a simple way to regular the indoor air conditions 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 disaffix more than 99 percent of all the airborne contaminants inside the house. Once both of us decided to go to the HEPA filter, the air in our home was noticeably cleaner for sure.
