Lennox 51M34 L3511C ComfortSense 3000, Programmable Thermostat, 5-2 Day, 1 Heat/1 Cool Gas/Electric

Best price I could find and perfect match.

These filters were the perfect size for my Carrier infinity series air handler. No need to buy the overpriced dealer installed filter for $400.00. This one was a little over $100.00 delivered. It looks just like the original filter.

I've ordered several filters from these folks. Awesome expedient service. Always!

My apologies for this delayed review. I had the pleasure of working with Dave Kline earlier this month ordering HVAC filters. This was the first time I contacted Atomic Filters and it was an excellent experience. Dave managed the order perfectly and I was kept informed regarding the expected delivery date. Indeed the filters were delivered ahead of schedule!!
I appreciated the excellent service by Dave. Most sincerely !!

I purchased four filters from your website. The filters were for me and three of my neighbors who have the same Carrier furnace. I searched the internet and found your website. The price appeared to be fair from what I had seen on other sites, so I ordered four filters. Our furnaces are about one year old so no one has replaced their filter as I write this. We do anticipate that we will soon have to replace the current filters. Your price was fair and the product was promptly received. We will use your website in the future when we need new filters.

I ordered these filters so I would have these on hand for my next service which is June. The filters seem to be just like the original filters that came with my air conditioning unit.

Great price fast service

Quick delivery as advertised. All good.

Im impressed by these filters, but even more so by this companys customer service. I had ordered the wrong size, so they cancelled and found the correct size for me. Had to wait to order because I fell ill, but they helped me and emailed several times back and forth until I could finially order again. Great service...thank you!

My order was delivered quickly and in perfect condition. Atomic filters also has a how to installation guide for assembling the filters. Great service.
Thanks!

We have used these filters the entire time we have owed our HVAC system. They do the job, are easy to store and set up, and exceeded our expectations. We are very satisfied.

Prompt arrival. Very good price. A little bit of a nuisance to assemble but it likely helps keep price lower than if it was already assembled and is smaller and less expensive to ship. Fit exactly.

Great price and perfect fit.

Order was received very quickly and the filters look to be well made and of qood quality. I also noticed these filters have more pleats than my previous filters which i hope gives better filtration. Very satisfied with the purchase.

The UV light retainer clips that I received from Atomic Filters to replace the deteriorated ones in my unit were a perfect fit! I did not see how they were installed at first, but they simply push into the hole where the old ones were located by simply squeezing the prongs slightly. Great customer service and support!
