Lennox X0445 MERV 10 Filter for PMAC-20C - 25 x 20 x 6 - Genuine Lennox Product

Have ordered these quite awhile

Easy to install just as described. I will be ordering again when I need another filter.

Cleans air as expected

The filter was just what I needed. Prompt shipment and delivery. Instructions on box explain how to install. First time took a half hour. The next will be much quicker.

We replace annually, works well.

It is a 50/50 chance of getting ruined in shipment! Mine had a crushed torn end. Attempting to repair it and use it... +++ A little tricky moving the separator fingers while installing; but, one gets better over time. The trick is to try to evenly space all the folds and then enter the separator fingers at one end and see where the doubles are. Then work from one side raising just one side enough to push just enough each time to fix the next double. I have been doing it for years now... I still get 1 or 2 dings (small tears). I dont worry about the tiny holes. You might use some tape on the input air flow side if needed?

The product did not fit it was the wrong model. I would give it a zero if I could

Filter came in a couple of days. Well satisfied.

No problem, fit perfectly.

This was cheap and much easier than searching the local brick and mortar stores for the right filter. It works just fine in my a/c unit.
