What is the best air filter for the furnace or air conditioner? Washable or disposable.
Washable filters are convenient, a lifetime filter that only needs to be washed off between uses. Some dealers will tell you that these are the best filters and they trap loads of particles. The indoor air quality experts at The Pure Air Store independently tested 5-leading brands of washable filters... The result? No filtration. The washable filters were only able to capture 15% of dust and debris that went through the furnace/AC system.
The verdict: Washable filters are worthless for filtering allergens. The only one catching most of the allergens is your lungs.
Disposable filters can cost anywhere from $12+ per year, from MERV-1 up to MERV-13 we've tested them all. First we tested filters that come from local retail stores, most stores didn't even carry the sizes we needed, but we were able to find our size in Filtrete Allergen Reduction. When tested, the material in the Filtrete tested at an airflow rate of MERV-11, a standard quality filter for trapping about 60% of allergens. It was effective, but over 40% of the allergens were still traveling through the filter and into the home, but it also restricted the MOST airflow, causing the furnace and AC system to work harder to push the air through. Finally we tested the MERV-13 allergen reduction
filter from The Pure Air Store. We tested an 80% reduction in dust and allergens in the air of over 300 homes. Customer testimonials on the Allergy Furnace and Allergy Air Conditioner Filter were great, 95% of customers would recommend the filter to their friends, neighbors and family. We also found that there was NO loss of airflow, the homes heated and cooled in less time than other filters used, with less energy costs!
Disposable filters trap more allergens and dust than washable filters, depending on the MERV rating, the higher the MERV rating, the better the filtration. MERV-13 is the best allergy furnace filter
and allergy air conditioner filter
on the market. For about $10-$20 every 3-months, the
MERV-13 is The Pure Air Store's Best Buy Award for 2013!
