This filter really helps my husband as he has pulmonary fibrosis.

These filters do a great job and Sam’s has them at a lower price than lower quality filters

Great value with instant savings

I loved them but I couldn't buy them again it's always sold out.

Great price, great filters. The four pack lasts all year!

Works and Sams has the best price

Very easy and convenient to shop online and the price was right!

Great deal didnt have to go to a different store to buy just one!

I have used these filters for years they always work well for what they do

Great price great filter when on sale at Sam’s
