Air purification systems usually come as a complete package, with a MERV 16 filter for hospital use, germicidal lights, and activated carbon filters for eliminating pungent odors like cooking or tobacco smoke. HEPA filters for ovens were initially manufactured to protect scientists from radiation when they developed the atomic bomb during World War II. Depending on the size of your home, you may have more or fewer intake grilles, but in most homes, the central air system has two vents covered with an air filter. These vents can come in a wide range of sizes, but they are usually larger than the vents that expel air into the house (which are usually similar in size to those of a sheet of paper). If it's too big, well, it just won't fit at all and you'll be left with unfiltered air until you get a filter that's the right size.

Thanks to their powerful filtration capabilities, HEPA filters are dense and can reduce airflow in some home comfort units. The size of the filter is an important factor in maintaining clean air quality and maximum efficiency in your home's heating and air conditioning systems.

Now that you know where to look for all replacement air filters, you're on your way to breathing better, cleaner air in your home. Technically, both components can be referred to as “ventilation ducts” because both are places where air circulates in the house. There are several different styles that work together with the air conditioning system, including HEPA filtration systems, air filtration systems, and multimedia air filters.
