Product review (1 stars): Too Long and Wide to Replace filter for Bionaire Model BCM4530
I've ordered this product in the past and found that's it's too long and wide (9"long X 6 1/2" high X 2 1/2" wide) to replace the original filter in the Bionaire BCM4530.  For this Bionaire model, I needed a filter that is 7 1/2 " long X 6 1/2" high X 2" wide.  Luckily, I owned a bandsaw which I used to trim the excess length and the filter could then be compressed into the filter compartment, but the situation was far from ideal.  I hope that I can find a source which sells replacement filters of the correct size.
