Nice fit, serves it's purpose without fail, can see the dirt easily.

We've been using 3m Filters since buying our home 6 years ago. I think these are superior filters.

I really like this level of filter due to our health, and a great value for a 4-pak.

Great product for air conditioning filtering

These filters are well made and effective

These filters are easy to install and do the job.

I like the package so I have some on hand.

4 pack of Filtrete allergen a/c filters work wel

Excellent filters at a great price. I love the multipack. It helps us to never run out.

Great price for this four pack of a somewhat uncommon size..
