I ran these in my WB 330.7. It says 7 x 14" but they fit fine. They're a little harder to clean than mesh much much easier than felt. Unavailable now but they may have some comparable
I was able to clean those with a garden hose but when it got cold here I I switched to premium aquatics 200 micron mesh socks so I can clean them in my utility tub. They are too long but still work. By work I mean they trap enough to become clogged and overflow.
