I have recently learned quite a bit about the relationship between HVAC and good indoor air quality. In my mind, I always thought that good HVAC meant good indoor air quality. And, that is true to an extent. HVAC goes a long way toward keeping our inside air healthy. The main way it does this is through humidity control. As the HVAC turns on to cool the house, it doesn’t just start pumping in cooled air from some canister. No, it begins the cooling process by removing warm air from inside and exhausting it outside. That leaves the cooler air to fill that void. However, warm inside air is not the only thing being exhausted. In fact, as the HVAC is extracting warm inside air, it is taking with it a good bit of moisture as well. This allows the inside air to have balanced humidity. Balanced humidity means mitigating mold & mildew growth. Mold is terrible for the respiratory system and the indoor air quality. However, introducing a whole house air purifier can allow the HVAC to take the indoor air quality to a completely new level. I found this out first hand when my neighbor got one in her house. She had complained for years about the smell of her indoor air. And frankly, she wasn’t wrong. But when she got the whole house air purifier, I was absolutely blown away at how clean the air was in her house. Not only was the smell better but the air was as clean as it could be. She now has the best indoor air quality due to a HEPA air filter for the HVAC and the whole house air purifier. It is actually installed inside the HVAC. The purifier kills all contaminants in the air as it passes through the air handler.
