Have used them before, work well, AC techs say they are good filters

Have seen much improvement in house dust & air feels cleaner

They work well and last 3 months generally

Great porice and love the multipak

These are really good filters and the price is good for the quality

I love these air filters and the fact that Sam's Club always has them in 14x20 size is a bonus.

Great filters at a good price.

These seem to be good filters and the price was good.

When on sale the best deal, years supply works very well on dust and particles

Great filters for a great price, best deal you can get in furnace filters!
