Review on 20 Pack 4" X 12" Activated Carbon Air Vent Filters For Home - Charcoal Filter To Reduce Dust, Dirt, Smoke, Pollen, Hair And More - AC Floor Register Filter For Home Vents by Robert Ogrodnik

Revainrating 1 out of 5

Blocks air flow too much. Do not recommend.

The air temp went up in the house as soon as I installed these when I had the AC on. Had to take them out and will try something else. Too little air flow will cause problems.

Pros
  • Easy to use and works.
Cons
  • Filter may restrict air flow, causing strain on heating and cooling systems and potentially increasing energy bills
