Have you ever checked which filter is used by your HVAC system? Probably the standard filter that comes in thickness of one inch. The most common dimension of such filters is 25” X 16″ x 1″. With such a small thickness, it is obvious that they will not provide superior quality of filtration. Sadly, their main function is protecting the HVAC unit from dirt rather than protecting you from allergens and pollutants!

While you can always purchase the filter that can catch minute particles of size 0.1 microns, you need a whole house air filter if you want the best air filtration. Also called a whole house air cleaner, this type of system is designed to clean your breathing air and not just protect your furnace components.

• There are different types of systems that you can purchase with some working better than others. If you have allergies or you need superior filtration, you’ll want a HEPA filter on this whole house system.
• These filters for HVAC systems normally come between 3 -5 inches in thickness. Hence obviously, just because of the added thickness they’re going to catch more dirt and debris than standard filters.
• HEPA filters do more than just catch dust, but instead catch it up to 99.97% of particles in the air that measure 0.3 microns or higher. That includes lots of allergens like pollen and mold spores as well as some viruses and bacteria.
• Of course, the key to this type of system working well is making sure that it’s clean and that you replace the filters as needed.

While few whole house systems claim that you only need to replace their filter once a year, the best way to judge this is to check it often by calling Atlanta air conditioning repair contractor and replace it when the need arises.
