A I alway purchase these filters as they work as advertised!!

Great value in the 4 pack

Definitely the best ones to use if you have a compromised immune system.

Reasonable prices high quality

Best filters! Would not use any other filer.

It’s good to be able to purchase more than one at a reasonable price

These are usually around $20 each anywhere else. These were 4 for $40 or &10 each

This is the second time, I’ve purchased these filters. These are great!

Helped so much with allergens

Best prices , one location
