Web Vent Filters

These wonderfully efficient web vent filters are made of a self-charging electrostatic material, which acts as a dust magnet for vent register systems. Dirt, dust, smoke and pollen sized particles are trapped when air flows through the filter, allowing the clean filtered air to pass back into your home. An affordable and simple solution for cleaner and more breathable air.

One package includes twelve 4" x 12" filters.

With a new neighbor above me I had heavy curry smells filtering into my apartment... causing the asthma to react. I purchased the WebVentFilters and Maintenance inserted them into all my vents. So far, they are doing a great job of filtering out dust, smells and mold smells.

Funny story...I started dating this guy that is allergic to cats I have two and couldn't come in my home, ever! We had to stop seeing one another after he had started taking shots and still couldn't come inside. Anyway, I saw your product and right away thought it couldn't hurt...So, I sprayed the furniture, carpets and then vacuumed. I did nothing else! He was able to come in and stay without any allergic reaction to the cats. Unbelievable product and I will continue using it, no matter what happens with this "new guy" Mary

Not only do these filters work, they work better than I ever expected. I have allergies and have two cats and a dog, all of which I'm allergic to. These filters keep the dander, dust, etc. from being recirculated therefore, allowing me to breathe freely at night for the first time in 42 years. I recommended them to my cousin and she is just as happy. I highly suggest these to any allergy sufferer.

Customer Q & A

Q1: Will the vent filters cause any potential damage to the central heating unit and outside unit?

A: Highly unlikely. While they are about a quarter of an inch thick slightly less, they aren't going to impede airflow too much at the point where it enters the room. They are designed mainly for visible dust, larger particles, and as such, they're not as dense as your typical furnace filter. And as nonwoven polyester, they should add very little, if any at all, pressure due to slowing airflow. Hope that helps!

Q2: Do you carry these filter wider size?

A: Unfortunately, no. They are all pre-cut.

Q3: the filters come in 4 by 12 inches, is it possible to by in a roll instead of pieces?

A: As of this time, we still haven't found an adequate source for large quantities this material. Despite numerous requests over the last few years, Webb will not provide us with rolls of the material, and several other manufacturers we have approached are either unwilling or offer products that lack the electrostatic properties that make the web vents so effective.

Web Vent Filter Reviews

Web Vent Filters

I have used these Web Vent Filters extensively in three different residences for the past four years. They are inexpensive, easy to replace, and they work really well at stopping dust before it enters a room.

I found that the Web vent filters easily slide between the two sets of fins in most air registers. I have heard from several customers that they Velcro the filters to the outside of the register, but I like the inside approach, because they are barely visible.

Per the manufacturer's recommendations, we do not use the web vent filters on every register, because that would be too restrictive to air flow, but we would like to.

What I like about Web Vent Filters
  • Very easy to install and use
  • Inexpensive
  • Great for trapping dust before it enters a room
  • Twelve 4" x 12" filters per package
  • Replace every 90 days
  • Can be cut to fit
  • Particularly useful for older homes
What I don't like about Web Vent Filters
  • The size is too small for some applications. Several customers have expressed interest in rolls of the material for bigger air registers
This is a fantastic and necessary product for anyone that wants to reduce dust in their home. The benefits of these filters far outweigh their cost. We are in the habit of changing the web vent filters every time we change our furnace filters. It is satisfying to take the dirty filters out, and it can be surprising to find that much dust and airborne visible particulate trapped in these filters.
