I like that the filters come in multi-pack. Delivery was fast and to my door. Thank you for having them avaolable.

Correct size. Perfect fit. Works great. You get what you pay for.

Genuine part, I've been ordering from here for years. Fast service and everything is perfect when I get it.

If you need a filter at a good price, call and talk to the parts department. They will help you get the correct filter the first time and every time there after

I’ve grown accustomed to the quick box version which requires assembling and has less structural integrity. This pre assembled version of my filter is the “way to go” moving forward. Love the fact filters are assembled in the States, ship in 24 hours and are shipped in strong boxes to arrive unblemished.

Looked everywhere, best price, fast delivery.

Good fit, looks like it should work fine

Since the day I had a newly installed Carrier HVAC system, I have wanted to make sure I purchase genuine Carrier products. And Atomic Filters delivered! I recommend purchasing the 2-pack. Save time and be ready when it's time to install a new filter.

I've been a loyal customer of Atomic Filters for about 25 years and will never change the kind of filter or the supplier. The "Atomic FILXXFNC0021 20x20x4.25 MERV 13 Carrier Replacement Furnace Filter - 2 pack" will keep your home very clean and dust-free. I also recommend adding an air-purifier-light to your air heating and cooling system. The two go hand-in-hand to keep your air clean and allergy resistant all year around. I've had multiple people every year in all 3 of the 2,300 sq ft homes I've lived in all these years, compliment me on how clean and crisp the air smells and feels in their lungs. I bought a 7-yr. old country home in SE Michigan, later a 7-yr. old beachfront condo in Pensacola, FL and then a 7-yr. old ranch home in The Villages, Florida. Switch to Atomic Filters and add a light-air-purifier and you too will begin receiving compliments on how clean and easy to breathe the air is in your home. The best does NOT always have to cost the most. Their hard working knowledgeable staff have always provided excellent quality customer service. You will never find a better quality filter or lower price anywhere. Please keep up the great work Atomic Filters!!!

This filter fits perfectly and is a terrific value. I have purchased from Atomic several times with complete satisfaction. The product always arrives quickly and in perfect condition. I will recommend Atomic Filters to family and friends.

Finally a filter that fits! Atomic Filters is my only go to!

Only place I buy my filters from once a year for the house save so much money going through you all.

Our package arrived damaged. We were directed to send photos of the damaged box and the filter.
The new filter was sent in a very timely fashion.

good product and service.
