Product Overview

MERV RATING: 11 - FPR "Filter Performance Rating": 6 - Specifically designed for families with allergies and pets. 53 times more effective than fiberglass filters and will last up to 4 months. During the manufacturing process, we charge the filter media with an electric current. This process allows the filter to attract very small particles much the same way magnets attract metal. The end result is a far more effective filter. The Electrostatically Charged filter media filters sub-micron airborne allergens like dust, dirt, pollen, pet dander, dust mite debris, microscopic allergens, smoke and smog. 100% Synthetic filter media will not support the growth of Bacteria, Mold, or Fungi in normal use.

This question is from 16 in. x 25 in. x 1 in. Allergen & Pet Protection FPR 6 Air Filter (4-Pack)

June 3, 2015

I believe this is the correct filter, however my unit has my 16x25x1 air filters laying sideways. So the width is 25in, the height is 16in, and the depth is 1in.

Is this the right filter for me?

Also, it says 4 pack. Just to clarify, there are 4 separate filters? My unit uses two separate filters.

Thank you.

Rated 5.0 out of 5.0 by Alergen and Pet Protection Air Filter I have ordered the Allergen and Pet Protection Air Filters before and was very pleased with them. They are the only brand my husband will use with our system. July 3, 2016
Rated 5.0 out of 5.0 by Filters out dust well! Like other reviewers we bought these filters to help better filter out dust in our house. One half of the house was really having dust build up. In the past we were using an inexpensive filter, but noticed out of all the filters in the house, it was always the dirtiest. (This filter was changed once a month.) With this new filter, the dust is now about half if not even less in the same period of accumulation time. Though we aren't getting miraculous results, we keep in mind this filter is the largest one in the house, near the back door where there is a lot of foot traffic. Plus, the pets and family spend most of their time on this particular side of the house. Therefore, it is expected more dust would on this side of the house. One down side is the cost per filter change. Yes, we are getting a much better quality product. However, after 2 weeks, we already need to change this new filter. Hopefully, this is because it is the first use and filtering out dust that was left in the air from before. Time will tell... I do agree with other reviewers that the size is smaller than other brands. It still fits, but is off by maybe 1/2". Before using this product, check with your HVAC company to make sure it is compatible with your unit so it doesn't restrict air flow. Note: The house is fully dusted and vacuumed every 2 weeks with spot dusting in this particular area a few times between full dustings. April 26, 2016
Rated 5.0 out of 5.0 by Great Product I have used nothing other than these filters for approx. ten years. They have always lasted beyond the three month service life. My Heat Pump tells me when to replace the filter if air flow becomes restricted. I replace the filters after the three months have expired. When routine service is performed the technicians have always told me that the filters are doing a very good job. October 15, 2014
Rated 5.0 out of 5.0 by Easy order hard to find size No stores in my area carry this size one filter lasted a month and caught a lot of pet hair with furnace running a lot March 1, 2016
Rated 5.0 out of 5.0 by Great air filter for the value I do not have allergy needs, so a 6-7 merv rating is fine for me. Great product for the price. February 10, 2016
Rated 5.0 out of 5.0 by Good Product Not the most standard size, tough to find in some stores. Very convenient and quick delivery. February 17, 2016
Rated 4.0 out of 5.0 by Great filter for a low price I love these filters. This is the second time I've ordered them from HomeDepot.com and I remain pleased with them. They do a great deal of taking particulate matter out of my househould air. When it's time to change them, I notice the house getting a bit dustier. I've recently (last 6mo) had some home renovation going on, so there's plenty of dust floating around, and I remain impressed that they take such a large chunk of it out of the air. I've even set up a reminder to reorder these before I run out (again!). January 22, 2011
