It’s now confirmed that I have a great deal to learn when it comes to Heating, Ventilation, and A/C and air quality. But I’m making strides, however still, I was pretty ignorant about both those topics for a long time, the system that there could be indoor air pollution was the furthest thing from our mindâ€¦ I mean both of us lived in a great house with super residential Heating, Ventilation, and A/C, then plus both of us lived way out in the country. The air here is about as pure as anywhere else on Earth maybe! But the lack of factories are highways and all that smoke doesn’t mean that there aren’t indoor air contaminants lingering in the house. Second, I thought the Heating, Ventilation, and A/C air filter was built to detach whatever suspended contaminants there were in the air. I mean, when I change the air filter it sure looks dirty. But that’s also what it was designed to do. Those cheap air filters I constantly used were made to trap anything that could hurt the Heating, Ventilation, and A/C equipment. It had nothing to do with cleaning the air or protecting our health, and for that I would need a HEPA filterâ€¦ And once I l received all about the Heating, Ventilation, and A/C and air quality, that’s exactly what I put in. But both of us also wanted to get the truly best air quality both of us could. The Heating, Ventilation, and A/C business told us that air purification was the only way to do it. So now both of us have a whole new home whole-house air purifier and it is just remarkable. The air is scrub and odors entirely fresh. And both of us have the best air quality money can buy.
