Helps so much since my son refuses to clean up after his cat

This is a great deal for these filters. They work great and last at least 2 months.

Great filters for the price.

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

Good price.. These need changing more often than than low efficiency filters

After using this once, I was amazed how much dust and other air debris it caught!!

Excellent air duct filters

3M Quality Filter at a great price.

Purchased because of the cost which was lower than buying separately.

These are excellent filters for an excellent price!!!
