Crucial Air HEPA Air Purifier Filter, Fits Whirlpool AP250, AP150, Part # 1183051K
I ordered this to replace my five-year old original HEPA filter for my Whirlpool AP25030S0. It fits perfectly and looks to be just as good as the Whirlpool. The only difference that I could see was the filter framing, which is a hard plastic on the Whirlpool, but just cardboard on this one. I'd definitely buy again.
Good replacement HEPA filter.
It fit perfectly in my Whirlpool Model 250 air cleaner. After one month of usage, it appears to be working satisfactorily.
fits perfectly together with prefilters of the same set. maybe even better than originals in that prefilters are tight and sturdy. less expensive, so a very good deal when bought together.
