Air filters have been used for many years, and are still an important part of your home HVAC system. When air is forced through your ducts, it passes through an air filter before it is put into the home. This air filter catches dust, bacteria, allergens, viruses, and other airborne contaminants. There are different styles and efficiencies that determine how well your filter works, and now filters are better than ever.
Types Of Air Filters
There are different styles, ratings, and types of air filters depending on what level of cleanliness you are hoping for. The main two types are called MERV and HEPA.
MERV – MERV stands for Minimum Efficiency Reporting Value and is the rating measurement system used for whole-home solutions. The higher the number, the more efficient the air filter, based on how small of an air particle they can catch from the air.
HEPA – HEPA stands for High-Efficiency Particulate Air Filter and is a rating measurement used for portable or room air purifiers. These are made to filter air at an exceptionally high scale. However, a filter rated this high isn’t ideal for whole-home HVAC systems as they create too much static pressure, which can damage your equipment.
What Does an Air Filter Reduce?
Air filters work at different capacities as we have mentioned before, and some are better than others. But still, they all have the same goal: To keep the air inside your home or business clean! Here are some of the airborne irritants they clean:
- Mold Spores
- Dust and Dust Mites
- Pet Dander
- Gas, Chemicals, and Smoke
