This item is functionally identical to the filters provided by Lennox. They work great and are priced right.

The only negative issue is that they seem to be a touch longer than 25", making it a bit difficult to get the filter cabinet door re-installed. Once the door is on, everything works great.

The finished size of the filter is not what is printed on the label of actual product, the finished size is 19 7/8 x 24 7/8 x 4 3/8. It is too large to fit without having to smash the filter so the lid closes and seals properly. The label states the finished size is 19 3/4 x 24 3/4 x 4 3/8, this is the size I needed for my unit and is what I thought I was purchasing.

We chose not to replace the electronic filter on a new furnace and instead, are using these Lennox MERV filters. Amazon offered the best price and we will continue to purchase them from Amazon. imho, they are comparable in air quality to the electronic filter we once had.

I was hesitant to buy a filter on line, but the was the exact match for what was in my furnace, as described on line and seems to be performing perfectly. I will order another one in 6 months.

Good way to get the good filters at a reasonable price. There are better filters (MERV rating), but for a much higher price.
