It’s rather presumptuous of you to even assume that it needs improvement, particularly when you haven’t even used it! So your “facts” are not facts.
As soon as our supplier gets stock we’ll be ordering one. If there are issues or places they can improve you can be assured that myself or someone else here will speak up about it.
Regarding filtering, I do run a basic paper towel filter on the primary solution maybe once or twice before changing it out. Visually it clears up the solution, but any observations regarding it’s effectiveness would be premature and anecdotal at best. And honestly, the only reason I do it at all is because I feel slightly bad about wasting 99% IPA when it costs us $30/gallon. I’m assuming once we receive the form wash I’ll stop filtering completely.
