Have not opened these yet but it is a product I use almost exclusively and is always a good performer.

Every. Last. Particle. They fit well and seem to have quality construction. Nothing to complain about!

I have been buying these filters for many years, and they really do the job. Specially, if you have allergies, I would recommend them. Good buy

Great filters at a great price!! You cannot beat anywhere in town and this four pack covers you for an entire year.

We purchase these quality filters (2-sizes) every 12 months at a great price compared to other stores!

Have used both products for a number of years. They both do a great job for there intended use. Both are bought from Sam’s at a good price

As soon as I installed these filters my wife stopped sneezing. She had been suffering for days. What an endorsement.

I love Filtrate 1600 because it’s great protection against dust and bacteria from A/C and heating units

I’ve used different brands and 3m filtrete is the best I’ve tried without the ones paying an expensive price.

These cost the same as the one filer that my husband was buying. Great deal. We'll see how it holds up to pet hair.
