Thought filter would be closer

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

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

Good filters for a fair price

Ive been using Filterbuy air filters in my Lenox A/C unit for several years. They fit well and are effective. I had once tried Filtrete filters from 3M but they had a foam strip that made them very difficult to install and remove. After using one I learned that its best to cut/trim this foam strip before installing but Ill never buy them again, lesson learned!
