Although some of us live in very messy houses, I think we can agree that we would all like to live in a house that is clean.
I mean I would love to live in a house where someone cleans for me all of the time.
The only way we can have this easily is by having an HVAC system. The HVAC system put air into our home at whatever temperature we would like. The best part is that it is not putting dirty or contaminated air into our homes. The air is fairly clean as much as it can be. The system cleans the air with something called an air filter. This air filter is what traps all of the dirt and junk that tried to come into your home. There are different filters you can buy. Every filter comes with a MERV rating. This rating is the minimum efficiency reporting value. It depends on the thickness that you would like your filter to have. In hospitals where the air is usually pretty sterile has a very high MERV rating. You will not find these thick filters in homes like that. The thicker the filter, the more stuff it can catch before it goes into your home. This is what helps to keep the air in your home clean as possible. Of course there can be other things such as bacteria, germs and pollutants that can enter your home that do not get caught in the filter. The can be taken care of with an air purifier. The air purifier gets rid of all of the things that the filter cannot catch. It makes for a clean and comfortable home.
