Product review (2 stars): It is too thin to work correctly without a modification. Cheap imitation of the original filter.
It is a cheap imitation of the original filter. In order for it to work, I had to add a "spacer" to keep it in place and tight enough to actually ensure air flow through the filter and not the gaps around.
The gap is about 4-5 mm (3/16" to about 1/4").
The filter itself seems very flimsy comparing to original.
It has 4 layers of the mesh, which should be enough, only if they were oriented correctly. They are layered one on another, with one only shifted a bit making the openings very large. Much larger than the original filter.
