Thanks for the input, ces.
I’m more concerned with the filter suffocating the fans airflow, than how well they filter dust.
They are about the same as the modright filterright filters.
I think there might be a difference, judging by a review here
(Reviews > Capt TW), copied below:START>>> very good filter (5), but cuts airflow quite a bit (4), looks (3)

I ordered 3 different filters to see which works best for me. I got the DEMCiflex 120mm Magnetic / Fan Dust Filter, the 120mm Blue Steel Mesh Filter / Grill and the FilterRight 120mm. The DEMCiflex has the best filter performance but on an Enermax Magma it cuts the airflow to half (subjectively not measured). The Steel Mesh Filter adds a really annoying high pitched sound when used and the relative big holes will most likely not filter smaller particles. The FilterRight cuts the airflow not as noticeable as the DEMCiflex but still I would guess it decreased by at least ¼ if not more. If you need a very good filter then the DEMCiflex is what you want. But attached it looks not as clean as the FilterRight. The best solution would be a combination of FilterRight and DEMCiflex. (frame of the FilterRight and magnetically attaching the DEMCiflex filter to it) <<<END
Antec P150/Solo – 70%
DEMCiflex – 50%
FilterRight – 25%
The FilterRight material might have potential if you could build an airbox type assembly, that increased the surface area of the filter significantly. Then 15% might be achievable, but then how to incorporate such a design neatly into a P150?
I’ll be going filterless for the time being.
