The Environmental Protection Agency (EPA) states that MERV 6 is the level that begins to protect air quality, so MERV 8 is a good minimum level for an air filter if you want to start protecting air quality. A minimum of MERV 11 is generally recommended for allergy sufferers. MERV 13 is often found in high-end homes, hospital common areas, and high-end commercial buildings that are LEED certified. A MERV 13 20x20x1 air filter is considered an excellent air filter for allergies.
Allergens such as pollen and pet dander can cause allergies, so this filter is the best choice for allergy sufferers. It's also the best option for eliminating other air pollutants that can affect the health of all family members. In addition to keeping your air conditioning system clean, the filter removes airborne particles and allergens from your home air. A dirty filter restricts air flow to the system's air controller, making it work harder to cool or heat the house.
Cheap air filters without MERV ratings can be so porous that particles that can damage the air conditioning equipment can pass directly through the filter. Discount Filters offers many different types of discounted air filters to help you breathe the air inside your home better depending on your specific needs. A good 20x20x1 pleated MERV 8 filter will allow good air flow for your air conditioning equipment and help protect your home's air quality. The industry standard for rating the efficiency of air filters is MERV, which stands for Minimum Efficiency Reporting Value. Keep in mind that when creating a filter with this tool, you must use the “real” size of the filter, that is, the size shown by the measuring tape, and not a nominal filter size. A dirty, clogged filter can restrict the flow of air from the oven or from the alternating current and cause system problems.
If you have pets, children, or allergy sufferers in your home or business, replace filters more often to maintain higher indoor air quality and keep energy costs down. When you check the oven filter on the wall grill or in the oven, you may see the MERV rating that appears on the filter. A MERV 11 20x20x1 pleated air filter will achieve superior performance thanks to its electrostatic properties to filter both the largest quantity and the smallest particles from the air your family breathes in your home. Choosing an appropriate air filter for your home or business is essential for maintaining good indoor air quality and keeping energy costs down. The EPA recommends a minimum of MERV 8 for general protection against airborne particles and allergens, while allergy sufferers should opt for a minimum of MERV 11. For superior performance, a MERV 13 20x20x1 pleated air filter is recommended.
