At one time I used a Ryobi ceramic sintered filter. It filtered very well, until the engine started cutting out. Solving that problem drove me nuts, until I exchanged the ceramic clunk for a felt clunk. Problem solved.
The area that can catch the minute debris particles in a sintered clunk is much smaller than in a felt clunk. Both have the same excellent capacity to empty the tank to the last drop and prevent air bubbles in a foaming tank.
I like the felt clunk therefore better. Come cleaning time, I can wash the felt, knead it until clean and fit it again. With the ceramic filter, all you can do is replace the unit, because it is very hard to get at the debris particles stuck deep down in the sintered body.
