Review on 🌀 10-inch diameter Solberg Filter Element by Ben Demers

Identical to Quincy brand filters. So much so that I'm willing to bet they're both from the same place and that Quincy is just asking too much. They are stamped "Made in USA" in the same place and "Patent Number" in the same place. Side by side they are identical in every respect. The only difference is that Quincy is around $25 and this one is $6 (at the time of writing this review). I change mine every 3-6 months because I have a machine shop so the compressor runs all day. 6 days a week. If you have a QT54 compressor, this is the filter you need!
