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

These have been great for my sinuses! They are all we use now. There has been a drastic reduction of dust on our hardwood floors.

Bought these as part of an email promotion but didn’t receive the credit. A trip to the service desk and four calls to members services resulted in a members rep repeatedly putting me on hold while I was talking and giving no response. Decided it wasn’t worth my time or frustration. Returned them.

Great porice and love the multipak

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

I bought this item for it's great quality at a great price

Nice fit, serves it's purpose without fail, can see the dirt easily.

These are great quality to keep your house air comfortable.

We've been using 3m Filters since buying our home 6 years ago. I think these are superior filters.

We have been using these for over 2 years and they are very effective
