Are your air ducts blowing dust, dust mites, molds and other allergens on you?

You probably have an air filter installed inside your A/C and furnace unit. But, after the air flows past the filter on its way to you, it picks up dust and microbes growing in your ductwork. Every time your AC or heater fan turns on, allergen and dust particles get picked up inside your air ducts, then flow directly into your rooms. Clean the dirty duct air before it flows into you home living areas with our duct vent filter attachments.

Stop suffering from:

• Asthma
• Allergies
• Bronchitis
• Throat irritation
• Headaches
• Eye/Nose itching
• Excess dust allergies

Elima-Draft Home Air Vent/Register Filtration Covers

Let's clear the air

The ducts of an average six room home carries through it approximately 40 pounds of dirt, dust and allergens each year. The EPA estimates that indoor air can be 2 to 5 times more polluted than outdoor air. Unfiltered indoor air is one of the top five environmental risks to public health.

But you can live healthier. Elima-Draft's allergy prevention filter covers help to reduce airborne allergens, mold, and dust particles from your central AC and heated air systems.

Elima-Draft Home Air Vent/Register Filtration Covers

Dusty air ducts are a breeding ground for harmful bacteria and dust mites that cause allergies and respiratory diseases.

How do these covers attach to vents?

On the inside surface of the cover are special, high-powered, neodymium magnets. The magnets line up to and securely hold to a steel vent or the steel screws of an aluminum vent. Install the covers in just seconds, not hours. No tools needed, and just takes just a moment to attach.

Improve your indoor air quality

Elima-Draft Vent Filters are even more important than the main filter for the heater and central A/C ("HVAC"). Almost all homes have an air filter (about 24" x 30"). It does a good job of cleaning the air just past the fan. But after that, the air flows through hundreds of feet of ducts in your home or office. The blowing air constantly picks up the growing mold spores, dust and other allergens as it blows though the air supply vents into your breathing air.

Air ducts can be far from sanitary: Dust mites, mold and bacteria can grow in them. Our Home Air Vent Filtration Covers, one in each room, will clean your duct supply air. These Vent Filters will clean the air after passing over mold and accumulated dust in your ducts.

Are you one of the 33 million allergy sufferers? Do you have other breathing issues, or need cleaner air? Breath easier with our vent filters.


Stop spending hundreds of dollars on air duct cleaning/sanitizing contractors. Save that money with these filters.

Frequently Asked Questions ("FAQ")

Q1: Which size should I buy?

A1: Measure the length and width of your vents to the outside edges, and buy the corresponding size. For example, if your vent is 9"x 9", then buy a 9"x 9" cover.

Q2: My vents are a little bigger than shown in the table above (e.g., 11.25" x 11.25"). What size should I buy?

A2: Buy the size that is a little smaller than your vent. The Elima-Draft Filter Cover will contact and seal against the surface just inside of the vent edge. And, our cover will completely cover the vent openings. Some examples:
• For a 11.25" x 11.25" aluminum vent, buy the ELMDFT11AF.
• For a 13.5" x 13.5" aluminum vent, buy the ELMDFT13AF.

Q3: How strongly does this filtration vent cover block/reduce air flow?

A3: Filtration Vent Covers do not significantly block the flow of air, unless they become extremely clogged with particles. In this case, the filter medium should be replaced.
