Gotta say, looks like you have it covered.
Not the biggest fan of mesh filter bags connected to the interior side of the inlet, but only due to the fact that all the ones I have encountered required awkward ergonomics to remove it and re-secure it back on to the tube by reaching into an often dirty waste tank through a small opening.
I like the fact that it is secured directly to the lid and that the whole assembly can be completely removed/cleaned/re-installed efficiently and neatly.
I consider the waste filtering systems on just about every portable unit I have seen as being completely inefficient, and major weak point.
Little acorn filters lacking the necessary filter medium surface area relative to the volume of waste encountered are ridiculous, not to mention the placement of them at the BOTTOM of the waste tank, where remedying any obstruction requires reaching into 2 feet of disgusting waste water.
Managing a mesh filter bag through a 8 inch opening where visibility is lacking is a joke.
No reason one should have to fish around inside a portable waste tank on a regular basis, other than for periodic deep cleaning at ones convenience.
It's just gross.
If a decent size metal filter basket would be incorporated into a full sized portable unit, similar to the way an Airhog has one incorporated to it, it would be a major advancement in porty design in my book.
