Air Filtration: Signs A Home Is Full Of Germs

Modern homes are built with air filtration systems for a reason. Home air conditioning and heating systems are designed to draw in outside air, which is then heated or cooled depending on the settings at the time, and then blown through an air filter. While these air filters are designed to catch most of the airborne germs and viruses that might be outside, occasionally these germs do get through. When houses contain a high level of bacteria, there are usually some clear signs that indicate the presence of these unwanted intruders.

Get the details on some of the most common warning signs the air in a home is filled with germs now.

Dirty Or Old Air Filters

Most homes contain at least one air filter connected to the air conditioning or heating system. For a home occupied by two to four individuals, most air filter manufacturers recommend changing air filters in the home every ninety days. For five individuals and up, or homes with pets, manufacturers recommend changing filters every sixty days. If a home’s occupants have any allergies, air filters should be changed once a month. If a home’s air filters are old or visibly dirty, it’s a good sign the home is full of germs. Thus, while these are good guidelines for changing dirty or old air filters, air filters should be changed if they are visibly dirty, regardless of how long it’s been.
