The filters were a bit short compared to what we originally had, but they work well and seem to be high quality

My only problem is that

My only problem is that The filters are about 3/8 of an inch narrower and a half inch less in height then what was original. It will work but Has to be put in carefully. I did get the order about four days before they said I would, which was nice, because after all the smoke in the west I really needed to change the filter soon. It seems to work well.

Buyer Beware. Cheap filters.

I wanted a filter that would fit where the Honeywell 16x4x20 fit before. This filter was barley 4 deep. Pleats not evenly spaced and many not glued on the edges. No way would a leaky thing like this pass a MER 13 test. Would not recommend to anyone.

I like the fact that although hard to find elsewhere, MERV13 filters were readily available and with quantity discounts.

The quality of the filter
on September 28, 2020

The quality of the filter media is there but the fit didn't work well with a Honeywell hvac filter housing. This runs smaller (19-3/8x19-3/8) and doesn't have a nice snug fit like my old Honeywell filters which run larger at 19-15/16. I do love that they are made in USA at a good price.

Installation was easy. They seem like they are good quality. Love that you can customize the delivery amount and timing of the subscriptions. And you can't beat the price. Happy customer.

I had to call to see why the sizing didnt match what I ordered even though the numbers matched. I live in Oregon an the smoke needs to be filter so I can breathe better. The person was very nice an is sending more filters an said I wont be charged an to donate the others charitable place.
