When it comes to keeping the air in your home clean and free of allergens, the best filter to use is a high-energy particulate air filter, or HEPA filter. These filters are made of dense layers of glass fibers, which are capable of trapping more than 99 percent of pollen, dust, and smoke particles. To determine how effective a filter is at trapping particles, many manufacturers follow the MERV (Minimum Efficiency Reporting Value) rating system established by the American Society of Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE).If you don't have allergies, a MERV 7 filter will work well in your home. However, if you have family members with allergies, it's best to opt for a filter with a MERV 11 rating.
This will help keep the air in your home cleaner and less irritating for allergy sufferers. You don't need to buy a special filter for allergy ovens either; any HEPA filter will do the job. Additionally, many filters come with a filter tracker that tells you how many hours your filter has to run before you need to change it. Your air conditioning system can also help filter out allergens from the air, but without the right air filters for allergies, you'll still have sneezes and sneezes all season long. HEPA air filters for allergies should be changed more often than common HVAC paper filters, especially during the high-pollen season.
HEPA filters can clean smaller particles such as tobacco smoke and medium and large particles such as dust and pollen from the air. They can also have a high CADR (Clean Air Delivery Rate). You can even order custom filters to treat specific allergens and impurities such as anti-allergic filters for pets, filters that absorb toxins, protect germs or eliminate odors.In addition to this, an activated carbon HEPA filter can be used to remove pet dander particles that cause pet allergies from the air in a room. This type of filter has four levels of cleaning to collect microscopic particles that usually cause an allergic reaction such as pollen, dust and pet dander.
The second layer is a medical HEPA filter that can trap small particles such as pollen, pet dander, and smoke. You can also find double-leaf window nets that filter pollen and dust online (search for “window air filter”). The Environmental Protection Agency (EPA) has said that HEPA filters can remove up to 99.97% of dust, pollen, and any airborne particulate matter with a size of 0.3 microns.
