It was a 22x23 MERV 8 Custon Filter. It is a good filter. Only problem that I had, is that in the next future order, I will need to adjust the size a little smaller. It was barely too big in fitting in my unit. I had to make some adjustments, but I will be ordering still from you when the time comes.
They arrived quicker than expected. They are a tiny bit smaller than stated and fit a bit looser but a piece of tape or two works fine. Our new Trane heatpump maker said to use Merv 8 with their system so we are going with their recomendation.
There are various brands of filters that sell 16x20x1 filters, and the variation in actual size is amazing. I'm really happy that these do fit my unit perfectly. And I am happy with the purchase and delivery experience as well--very prompt.
