If you want a healthy, germ free environment, a single great way to do so would be to get HVAC duct cleaning.
A HVAC duct cleaning detachs all of the dirt, hair and dust up in the duct works, and the thing is, since people can’t see their HVAC duct, they don’t realize how dirty it legitimately is up there! But there are a few signs that you might have legitimately dirty HVAC duct, one is allergies.
It is normal for some people to have allergies, however a lot of times what people suppose are allergies are legitimately just irritants in the air. I have had so multiple people come to me after getting a HVAC supplier to wipe their A/C HVAC duct, and they would tell me how their symptoms cleared up soon after, and really if you want good indoor air conditions in general, a HVAC duct cleaning and an whole-house air purifier are a good way to go. Anyways, I ended up reading this myself a few years ago, when I had my first heating and A/C HVAC duct cleaning. A team of Heating, Ventilation, and A/C repairmen came out to wipe the ducts and it took a few hours. When they were done though, I was surprised and disgusted to see that the cloth they used to wipe the inside of the Heating, Ventilation, and A/C component was literally black. It was so incredibly gross and since then the people I was with and I have made sure to have the HVAC duct cleaned every year or more than one. This way I can ensure better indoor air conditions and cleaner air, and that makes me happy.
