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

Four pack of 12 x 12 air filters cost $20 ea at Home Improvement stores. So four pack for $39.99 is a deal.

Removes just about everything but the air...works nice and lasts about 3 months, easy to replace. The multipak is a good value.

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

I change my furnace filters every time the season changes. This makes it handy to order a year's worth every spring.

It's great to grab a bundle of these to have on hand, now I have no excuse for not changing the filter regularly

Filtrete filters are generally well rated by Consumer Reports. Have not used this one previously though.

I got the filters without any issue. I've installed one and will know in a few months how well they work.

Since using these filters, my allergies have been much better. I like getting 4 at a time instead of one or two because I have several registers.

I've been using these for years. I buy them when they go on sale, so I'm always stocked up. The keep my heating and cooling system in great shape!
