Product Overview

The Honeywell Superior Allergen is made of a reinforced pleated media with a large surface area which improves the efficiency of its dust-holding capacity. The unique construction of Honeywell Superior Allergen filters requires less energy for lower energy cost. Its electrostatic charge helps attract particles “magnetically” that otherwise would pass through. Housed in a recyclable clay-coated moisture resistant frame, this filter captures particles as small as 1 micron. In comparison, a human hair is approximately 100 microns in size. The Honeywell Superior Allergen is effective against the following contaminants: dust/lint, airborne dust mite debris, pollen, pet dander, mold spores, bacteria, microscopic allergens, virus carriers and most smoke.

  • Filter performance rating (FPR): 9
  • Filters down to the micro particle level
  • Electro-statically charged
  • Heavy-duty moisture resistant frame
  • Lasts up to 90 days
  • Check out the features for air filters that are FPR 8-9

Customer Questions & Answers

Can a 25" x 20" x 1" FPR 9 AC Filter make your AC work harder if your air handler is in a confined area under a stairwell

Hello, I was wondering if a FPR 9 AC filter can cause problems with your AC if the air handler is in a confined area under a stairwell. I have been reading that there can be issues with air flow as the filter is quite thick and I wondered with the air handler being in a confined area under the stairs if it could cause problems with the AC unit. Please advise.

The FPR or MERV rating tells you how well it filters. When NEW all of the pleated filters will pass the same amount of air. Where you can get into trouble is the higher the rating the faster the filter will clog. So if you have a fairly dusty (or pet hair) house using a high rated filter will mean changing it more often than a lower rated one. For instance a spun glass filter rates at the bottom for filtering but will last longer before it clogs. SOOOO I buy MERV 11 filters and change them at 60 days rather than 90. It's a cheap way to get well filtered air and protect the furnace.

One piece or two taped together?

I ordered Flanders 18x36x1 filters and was surprised when they were really two smaller filters taped together. I was wondering the Honeywell version is really one continuous filter or do they do the same shortcut?

21-1/4 in. x 23-1/2 in. x 1 in. Superior Allergen Pleated FPR 9 Air Filter is rated 4.4 out of 5 by 321.
Rated 1 out of 5 by from A total ripoff My friend's home requires a special filter size for the return. Why this would be so on a newer home, I have no clue. But, being a General Contractor and Home Inspector, having the correct filter for the system is a simple but effective way to maintain a healthy HVAC system and air quality in the home. So, I go on to the Home Depot site to order a "custom size" filter that I had to wait 2+ weeks for. When I received it, what did I get? Two (2) filters that were taped together! I could've had my 10 year old nephew do that! A total waste of time and money. One star is too many for this but they don't allow zero stars.

Rated 1 out of 5 by from Size is way smaller than labeled I purchased a Honeywell 21-1/2 in. x 23-5/16 in. x 1 in. Superior Allergen Pleated FPR 9 Air Filter from Home Depot. Model # 90901I012152331 The dimensions are wrong on both sides. While it was labeled 21-1/2 in. x 23-5/16 in. x 1 in it actually measures 21-1/4 in. x 23 in. (a 1/4" off on each side) This is too small from my A/C.

Rated 4 out of 5 by from Ordered 2 of the same custom size. One was reinforced with cardboard diamond shape on both sides ... Ordered 2 of the same custom size. One was reinforced with cardboard diamond shape on both sides and one was not. I am using the reinforced one first & it seems to work well & be strong enough to not bend much. I don't know how the other one will perform until I use it next. I feel both filters should have been made the same way. Also, I would like to see reduced pricing when buying more than one filter.

Rated 1 out of 5 by from never again I’ve used Filtere (sp?) filters in the past & was very satisfied. HD must have switched to Honeywell for the profit margin. Cheap materials & the frame collapsed easily when installing. Save your money.

This is an excellent product and difficult to buy because it is not stocked where I shop regularly. My only issue with this product is the same experience I have with all of my Honeywell filters. The price is very steep, but it is suppose to cover your filtration needs for at least 3 months. I only last for 2 months. We have allergies and live close to a highway/construction/industry around the corner zone. Maybe that's our issue, but this product certainly stops the allergens for dust providing clean air. If you time your filters and change them around about the same time, you can tell the difference in your breathing, wheezing, and sneezing.

Rated 2 out of 5 by from AC Filter arrived slitghly crushed This size has now become a special order and I am just a bit disappointed that the filter arrived slightly crushed. Not the edges, but the middle part where the ridges formed a wave pattern to catch the dust. That part is crushed. I am still using it, but I am sure that the fan needs to work a bit harder to move the air through. Who ever boxed it in the warehouse is to blame for this, I am sure it is not a manufacturing problem.
