The Carrier filters arrived in good shape. I will be purchasing again in the future.

Carrier infinity Air purifier

I have been purchasing from Atomic for several years. I like the service and the ability to adjust delivery dates if necessary. The product comes well-packed and the shipment is always on schedule.

As always, great service and speedy delivery. I appreciate being able to save money on this Atomic compatible filter. It fits perfectly for my Bryant furnace and works just fine.

Filters are great, I only have to change them every 6 months, and they a area perfect fit

Filter replacement

I bought a compatible Carrier filter and had issues with it. The first one worked without any problems but the second one didn't work. Thanks to Kevin and Dave they fixed the issues quickly. I'm happy with their outstanding customer service and keeping the prices lower on their filters.

Excellent air filters and system, but immensely expensive

The Bryant/Carrier filters are a built in recurring expense for the Carrier HVAC system we installed. We didn't know that they would be so amazingly expensive, with the price rising every time we buy replacements. Of course this filtering system is outstanding, but it carries a very high cost that will only get higher as time goes by.

Great quality

Perfectly fitting and great quality will order again

40% less than I paid last time

I was amazed that the price for the same filter was so much lower than I had been paying from a different company. I wish I had known of Atomic Filters years ago. I will now look to them first for all my filter needs.

good filters

Good quality filters at a good price


Fast, prompt service, been ordering the filters for about three years now, price lower than anybody else in the US

Quick delivery, always in stock, reasonable pricing

Best Place To Meet Your Filter Needs

This is the only company I can find the 3 filter sizes I need in one place. Prices are very competitive too.

Good purchase.

Quick delivery and it fits better than original filter. Time will tell how long it lasts.

Everything as expected. Good product.

Good price

Filters from Atomic Filters are of very good quality, and the price per filter is better than the prices in big box stores. Bought these a second time as the first batch I bought noticeably reduced dust in our home. Shipping was good, Filters arrived three days after ordering.

Perfect fit

Arrived on time as promised and was packed well and a perfect fit.

Nice Fit, better price!

We have two Carrier systems in the house that use these. The original installer who services the units marks up the filters slightly. So, I found these. I replace the filters, they do the PMCS checks on the units, and I am able save a little bit of money. In fact, when I removed one of the old filters originally installed last year by the installer, it appeared remarkably similar to an after-market brand. The other one had Carrier stamped on it. I don't think you can go wrong with these. We don't have allergies, but they work just as good as what was installed with the units when new.
