Good job of reducing dust

Absolutely great for those that have horrible allergies

Great for price to have ready all year long

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

These a great deal , liked the product , just we have a whole protection of the allergy

Very good filter and great at this price.

Can't find these anywhere but Sam's!

Works and fits perfectly!

they will last for all year

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