Model

The Filterbuy replacement air filter 21x21x1 (actual measurements: 20.88" x 20.88" x 0.75") ensures that your furnace, air conditioner, heat pump, or HVAC system is circulating the cleanest air possible to help preserve your budget and healthy lifestyle. MERV 13 synthetic media (comparable with Healthy Living Ultimate Allergen Defense MPR 1500 - 1900 & FPR 10) is recommended if you have a respiratory illness (such as asthma) due to its capability to trap 98% of airborne particles, protecting your home or business from bacteria, smoke, smog, debris, lint, pollen, mold, dander, and other forms of dust without impacting air flow. High quality construction features an electrostatically charged design with 16 pleats per foot that captures more harmful particles and prolongs the products lifespan by three times that of fiberglass models. Plus, our industrial grade beverage board frames are paired with dual wire backings that significantly outperform traditional cardboard compositions by improving structural integrity with their ability to endure temperatures up to 200 degrees Fahrenheit and withstand exposure to moisture. Installation is also made simple with the addition of easy-to-understand arrows that help identify the direction of air flow and subsequently the way the filter needs to be placed. To top it off, all our components are 100% manufactured within the United States and designed with recyclable materials, providing an eco-friendly alternative to enhancing your air quality.

Filter Variety

The filters that I've used for the last 10 years measure 23 7/8 square and fit snuggly into the return air receiver. Your filters measure 23 3/8 square and barely cover the edges of the receiver allowing blow by around the edges. I had to tape them in to keep this from occurring. Not pleased with the product at all for this reason. I don't believe I'll purchase anymore regardless of the filter quality which I don't know yet. I changed them quarterly and my ducts are super clean after 10 years and I want to keep them that way. I liked the price, but I guess I found out that you get what you pay for. Disappointed!

Smaller than standard filter.

Filterbuy

The filter itself wasn't the normal white color that I expected but that didn't seem to affect its performance. Overall it still looks and performs like a typical filter. No issues at all!

The filter itself wasn't the

I feel like I immediately felt the air in my home cleaner. Our furnace has a built-in air purifier and my home was less dustier and it didn't have the usual after cooking smell that lingers for a day or so.

Clean home

This is very comparable to the name brand filter as far as the construction and appearance goes and lasts for a couple months without showing any signs of deterioration.

Good filler great price

I was pleased to find an American made source for filters that saves me money and delivers them right to my front door fast. The filters are as good or better quality than any I've used in the past. I highly recommend that you give Filterbuy a try.

Great way to buy filters!

I am very happy with my filters. I needed an unusual size. I previously had to buy 3 smaller ones and duct tape them together every 3 months. Your filters came quickly, damage free, and is a much better quality. It took less than 30 seconds to change out and I noticed a difference in my air quality that same day. I bought a year's supply, so I will definitely be buying again next year!

I am very happy with

Great deal on these filters. We have three rescue cats, one of which I am allergic to. I've noticed less issues since switching to this brand. I change my filters every 45-60 days and noticed the filter went in bright blue and came out a medium gray color.

Great home filters at a great price. . .

After many years purchasing the same box of filters I got just what I asked for - 24X30. Somehow I missed the small print: 24x30 (actually 23 1/2 x 29 1/2).
My fault. This company has been great to deal with, and I highly recommend them on quality and value

Actual Size

The product was received slightly bent but still usable. I have visible evidence the filter is working by the amount of particles on the old filter. I do wish the size would be closer to the advertised size. I have to use small pieces of cardboard to eliminate a whistle from an air gap.

Good filter but could use small improvements

The filters were too big and FilterBuy would not let me exchange or refund them. I now have to cut all my filters to get them to fit or just throw them away. This was not a good solution.

They are too I would not take them back.
