Exactly as pictured

Kinda a pain to assemble but worked as directed. Will definitely buy again.

Exactly the same filter that came with my Trane HVAC, fast service and saved money buying thru Atomicfilters. Will definitely buy again. Thank you

Christopher Mills
Perfect as always!

Quality filters and fast shipping. Perfect!

My new TRANE filter system

Installer of my new TRANE HVAC recommended that I order filters online instead of lettting the dealer install them. He said I would save money and I know it was well over $25.00 on a pack of two. The filters I got from Atomic were an exact match for the filter that came out. Can't beat that

Fast Delivery

Quickly arrived at a reasonable cost. There has been availability issues with other providers, so I was happy to find this firm.
