The FiltersFast 4-inch Air Filters (FFM136) have a MERV 13 rating and are useful in a variety of settings, including homes, offices, and industrial sites. These MERV 13 filters effectively reduce pollen, dust, pet dander, mold spores, and dust mites, as well as bacteria, smoke, smog, and other allergens. The higher quality construction from these 4-inch filters benefits health and respiration, including alleviating problems with allergies and sinus irritation that might lead to itchy throat, watery eyes, coughing, and sneezing. 4-inch air filters are also more effective than thinner filters because their larger surface areas are much more durable. FiltersFast air filters are affordable without sacrificing quality. These HVAC air filters arrive in a variety of sizes to meet your air quality needs.
