To big, sizes are all different

Feels like a well made filter, not flimsy.

Great filters, love them so far. Only downfall they went onsale right after I had purchased them.

Great product and price. Delivered promptly

I was sent the wrong size. It was way too small.

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

Have allergies so must use a strong filter. Have been buying this brand at a big store and paying about same for two!

Just What I needed. I love these furnace filters. I have little or no dust & the house spell fresher

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

I was sneezing all the time from cheap filters. I switched to these and everything cleared up within hours.
