AC unit easy to install
These were recommended by our HVAC installer to change out every three months. It catches a lot of hair as we have three pets and the dust in the air. Seemed to work great air quality is much better and the steadiness when we are changing, the filters works well.

Fit My Furnace Perfectly!
My first order arrived damaged. It was cheerfully replaced. I have several animals in my home and I change my filters once a month. This value pack really helps take the sting out of furnace filter replacement. So far, they seem to be doing the job.

Simple good filters
There a many filters claiming all sorts of filtration capabilities, and I am sure some actually achieve great things. Unfortunately, most furnaces (like my Carrier) don't fit the filters tightly enough to block the flow fully and some air will just blow past ... making better filters questionable.Coupled with this, a furnace expert that installed a new unit in my home explained to me that unless your furnace is specifically sized for special filters and has the right mounting box, these better filters will reduce the airflow and hence circulation in your home, and in the worst case, can damage your furnace/AC due to overheating or freezing from the reduced air flow. Their recommendation: go with a MERV 8 (like these) or at the most a MERV 11. Their recommendation for extra filtration: install whole-house floor mounted HEPA filters rated for the space, or a more expensive electrostatic unit on the furnace that doesn't restrict the flow.These are solid MERV 8s that I have been using in my furnace for 3 years now (changing out about every 3 months) without issue. FYI - I did try a MERV 11 that actually pulled out of the box mount and ended up in the bottom of the plenum below it. I don't know for sure, but I guess that moisture built up on it (it was slightly damp) and cut down the airflow causing it to be unseated somehow.I will continue to buy these filters for my home system.

Buyer beware
Filter does not fit properly, not even perfectly square. Wanted me to pay shipping return. Buyer beware!
