Thought filter would be closer to 5 inches in thickness. The Honeywell brand i was using has the exact same dimensions as filterfast but call there's 4 inches. See photo

Quality of the filters

Had to buy a new HVAC system that came with one of the filters so I bought 3 more. Wife has asthma and we believe the foliage helped her breathing. So, I bought 3 more.

You keep changing the sizes by little amounts. These didnt fit well. SO FRUSTRATING. I had to jam it in and am sure will need to rip it apart to get it out
