I also like the ease of getting several at once. These work great though, they really help cut down on the dust in the house.

Everything is great about them. And I've ordered from others online and they come bent and messy, these are packaged perfectly! Very happy!

I switched from a washable filter after I looked at the MERV rating on the washable and was shocked at how low they are. I can already see a big reduction in the amount of dust downstairs. I am ordering another case of filters for my upstairs unit to replace that washable filter also.

I would not shop elsewhere as this is the most convenient and has the best price on filters.

Great filters take care of the dust!! Our HVAC 'man' says they make the system work harder--probably an endorsement of the MERV 13
