These are wonderful and they work great. I have asthma and my husband puts the filters in for me. If you have asthma, this is what you need. Thank you.

We use the filters to build a filter for inside the house. We learned about it on "This old House" on TV. It cleans a lot of air in the house.

Central AC filter
on August 9, 2022
Posted by: Anonymous
I bought the MERV filter to use in the ceiling air intake of my central AC system. It works fine. Before replacing the plastic mesh filter that was there, I thought the MERV filter might slow the air flow. It didn't. The cool air comes through as strong as ever, and cleaner.

Love these filters.

I have a couple dogs & terrazzo floors so I change my filters every 30 days. I started using these filters last year when I first purchased this home and added central air. A year later it still smells fresh walking in Im sure its due to good filters helping me to keep it clean.
