Lasts up to 3 months but have to change every month.

Great Product, catches a lot of dust.

Great price and great product

These filters work well and fit perfectly, amazed at the amount of dirt these collect

Good price for quality filters

Great to have on hand without going to the local supply store.

They work well and reduce dust in my house.

Clean my home air so well

These were too big for my opening. I returned them.

I've been looking for these for a while. They've been out of my price range until now
