Very good filter and great at this price.

These filters really helped keep the in-house air cleaner when experiencing seasonal allergies.

These were hard to find even in the home improvement stores.

This 4-pack is a trendous savings over purchasing the filters individually.

Great filter and great price per filter. Definitely lasts a full 3 months.

A lot cheaper and same good quality

Works, protects against allergies and those cooking odors don't linger

These fit perfectly. Great value for the price. Will purchase again.

Well worth it! Have in door pets and they work like a charm.

Works and Sams has the best price
