I've always used this brand, not sure if its better than generic ones. Price is $$$

These were just what I needed for my furnace/AC. They really keep the dust down in the house.

Great filters for that price

They work well and last 3 months generally

Very easy to install, great to trap and filter dust and keepbdust down.

I like this better than the cheaper ones they work a lot better

Have used these filters for years with good affect. They do a great filtering job for up to 90 days.

Love that Sam's Club sells a multipack of these filters. Usually can find them in single or double pack at other places.

Filters are wonderful. I can't say too much for the shipping. The package was smashed and filters were all smashed, but I fixed them up.

I hope these do the trick bc I have horrible allergies >> new filter plus new air purifier should do the trick.
