Filter replacement

Replace my original equipment filters with atomic house, brand filters.
Filters are very good quality, same fit size style and function. Would definitely recommend these filters as replacements.

Great customer service

Great customer service , however shipping was slow to get to me

Good filters, fit and finish. Fast delivery.

Now that Skuttle is out of business, I thought I wasn't going to have any more filters available. Atomic Filters to the rescue. These filters fit just like the OEM ones. Looking forward to ordering more.

Filter works fine and Atomic Filters is Great

Not a big fan of the quick box filters or the fact that Trane uses weird sizes you can't buy at a reasonable cost but the filters work and Atomic Filters shipped quickly and had the best pricing. Can't recommend Atomic Filters more highly.

Missing the logo

These appear to be identical to the name branded ones. Without the name. So I am satisfied.

Great service and prices

Quick and easy process that is much cheaper than the stores!

HVAC Filters

Very quick delivery. They fit perfectly. Doing the job. No dust in the house.

Works great

First time buying replacement filters from this company for my Trane furnace. Delivered quickly, fit perfectly, and save me about $20 compared to other sellers. I'll be buying from this company for future replacements

Honeywell replacement filters

Filters are very well made and fit perfectly.
Service at Atomic was outstanding and very helpful throughout the process.


Filters arrived quickly, very satisfied with product quality and service.

Effective odor reduction

The X8791 metal mesh filter does a great job in reducing household odors as I have found as a long-term user of Lennox PCO20-28. However, X8791 works in concert with the Lennox X8794 UV lamps which do go bad after awhile. I am awaiting a shipment of those lamps as ones I had in place for a few years are not producing sufficient illumination to work with the metal mesh filter. Be certain to check all elements of your Lennox system.

Good service

this is our second time ordering filters for our furnace. They have arrived quickly and in good condition.

UVPHOTOMAX is awesome

I have had these installed everywhere I have owned a house. The price was fair and installation is easy. Keeps the air in the house clean.

Great Replacement

I have furnace guy's clean and inspect a couple times a year. Lately whenever they come something ends up broken.
The price was right and the system works as advertised. Also your shipping method was spot on and was free. Thank you again.

Filter inventory

awaiting time to replace the filters in the Spring!

PCO Filters

Atomic Filters are BETTER than the others you will find online and a little less expensive too!


Great filters. Will be ordering more in the future.

Good Prices

The prices were good along with excellent delivery times.

Carrier Alternate Filter by Atomic
