Here is the site for the Wynn woodworking filters. I believe the correct model is the 35 A, I got the 1 micron unit, which is more, but just right for indoor use. https://wynnenv.com/products-page/wo...ilter-pricing/
This is a standard model, V35A274BLOL Cartridge Kit Open at the bottom with gasket closed at the top. 17.5” x 23”, outer cage, no inner cage 274 Sq. Ft. of MERV 10, 80/20 blend filter media Included: Instructions, (2) clear poly dust bags, (3) FGL-U latches used for mounting the filter. Price: $129.00
These are pricey, but if you blow them clean once in awhile, they will last for a very long time, particularly in a small home shop.
As I've said, I don't get a toaster for sharing this, but up to now, none of my home made solutions hold a candle to the effectiveness of this DC system, particularly with the Wynn filter. I am a throat cancer survivor, believe me, you don't want to breathe sawdust, which often contains carcinogenic chemicals.
