Have only used one of these. My first time buy but happy with it

Nice filters, good price for 4

Works well,keeps air clean.

Really like tbese filters

Saved some money by buying multi-pack at Sam's instead of more expensive Lowe's.

Been using for years, good product

Quality filter and the ability to be reminded when to replace is an asset for sure !

Installed 2 of them ... worked well. Had a good "feel" to them.

Great filters at a very good price

Package size covers about one year.
