Lennox 21x26x4 MERV 16 Upgrade Kit X8344

Filter fits and appears to be a proper replacement for the original Carrier filter. We'll know more over time as to how it stands up to use.

great

I found ordering from Atomic Filters to be easy. Information was presented well and complete.
This is my first order from Atomic Filters but it will not be my last. Price and delivery were as outlined when placing the order.
Filters were exact replacements for my furnace and arrived on time and in perfect condition.

This device is performing as advertised and seems to be helping with everyone's allergies. Everyone agrees that cooking orders are also quickly dissipated . Love that the item is self cleaning and maintenance free.

We would recommend Atomic to everyone who could use their products and services. Outstanding!

Original quality filter at one of the lowest prices on the Internet. Fast delivery and easy shopping experience

We installed our Bryant air cleaner/purifier around 6 years ago. These filters are very expensive and at times we run without. We actually see little difference when we have this over rated high dollar filter in place.

My 1st time to order from Atomic Filters. Needed a new size filter 20x30x2 for my AC Unit. There were NO Filters available at my local Big Box Store that were the 2” depth type of filter we needed. Found Atomic website and ordered exactly what I needed for a full years worth of filters. Price was Great, and I had my new AC Filters within 1 week of ordering them. I highly recommend this company for your AC Filter needs. Thank You.

I ordered this product for the first time from your company after having ordered the same product from another company last year. This experience was "great." The product
ordering process was easy and the product was exactly what I expected and it arrived in a reasonable time (however not Amazon's one day service). Based on my experience I will order it again when I replace them in a year. Thanks..

I was really excited about by new AC...until I tried to find a filter. No one had this size until I discovered Atomic Filters. Price was great. Delivery was fast. Just ordered a few more so I don't have to stress about this in the future.

This is a quality filter cabinet that has several different MERV filter options for the homeowner to choose from within its CFM rating.
It is easy to assemble and install. Filter changes are an easy task to complete.

Great Replacement HEPA Filter for Levoit air purifier / filter ~ at a significant savings !
I really recommend ATOMIC for your filter needs.

Installers or our Lennox HVAC strongly recommended using this exact filter and replacing it every 11-12 months. Atomic Filters had easy online ordering and extremely fast shipping at a good price. I appreciate the subscribe and save feature because now when a new one shows up I know it’s time to replace it.

Great experience, will buy from again

Good price and good product!
