The 3M Filtrete Dust & Pollen Furnace Filter is an electrostatically charged furnace filter ideal for high velocity HVAC systems. 3M Filtrete filters are an economical upgrade from cheap one month filters. The 3M Filtrete Dust & Pollen Filter is far more effective than the average washable or fiberglass disposable hvac air filter, which normally does not even remove dust from the air.
The Dust & Pollen "Light Blue Series" Filter Reduces:
Pollen - when ingested into the human body causes the immune system to produce large amounts of antibodies, which in turn causes chemicals such as histamines to be released. The release of these chemicals causes such symptoms as sneazing, runny nose, and watery eyes.
Mold Spores - when mold found in wood, ceiling tiles, wallpaper, paint, carpet, sheet rock, and insulation is disturbed mold spores are released into the air. Mold spores can cause symptoms such as sneazing, runny nose, and itchy or watery eyes.
Dust Mite Debris - a combination of dead skin and dust mite feces, this debris lives in our beds, chairs, couches, and our children's stuff animals. Dust Mite Debris is almost as effective as pollen at causing symptoms such as sneazing, running nose, and watery eyes.
Household Dust - dust accumulates everywhere in your home; carpets, tables, TV screens, clothes, walls, etc. Simply walking around in your home may disturb or "stir up" dust into the air which can irritate your immune system.
Lint - minute pieces of fiber that come from fabric, plants, paper, etc. that float around in the air. Lint can cause allergic reactions in some people.
The 3M Filtrete Dust & Pollen Air Furnace Filter lasts three months and meets the American Lung Association Health House Indoor Air Quality Guidelines.
