Lennox X6669 MERV 16 Filter 21x26x4 Genuine Lennox Product

I received this order within 2 days of ordering. A very well made filter and it is not easy to find. We will definitely continue to order from Atomic .

OEM filters at a great price.

This is not meant to be a glamorous review .. it works .. came on time .. was really well priced

It takes good people to pull this off .. no Amazon corporate.. direct business

Its a great filter lower price.

First time to order and was very satisfied with the process.

The lamps work great and were priced great! They were really not packed well though. They were packed loosely in a box that was far too big, but somehow even with the way the deliver guy throws boxes around they made it without being broken.

Correct filter delivered promptly. Thank you!

Removed the same type from my new heating unit and it worked well, sure collected a lot in the filter and that is why I ordered the same filter

They arrived promptly and in perfect condition. I expect to use Atomic again.

Great product! Works well!

Only company I can find that Carry my AC filters. Very fast on delivery ! Exceptional service!

First time ordering filters online. Bought locally previous 9 years. Couldn’t be happier. Product was exactly what I needed. Great price and quick delivery.

Filter was exact replace as original, last as long or longer

These filters are a Pettit replacement fit for what I needed.

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
