8171434K Carbon Pre-Filter Replacement Compatible with Whirlpool Whispure AP450, AP510, WP500 & Kenmore 83200, 83375, 83230 Air Purifiers by LifeSupplyUSA (4-Pack)

Perfect fit and fitment. Quality seems great. No issues at all.

Filter was exactly like original and fit perfectly at a much better price. The filters for our air cleaner have to be replaced fairly often and they are way more expensive than they should be. I checked the size of these and MANY reviews before I bought. And I wasn't disappointed. Thank you!

Good product, will keep.

It fits well and seems to be a quality product. Be advised, it DOES NOT come with a pre-filter.

Perfect fit on my Sears HEPA air cleaner.

This replacement filter is the same product we have used in the past. It does what it's supposed to do.

It fits my Kenmore air cleaner.

These are very effective filters and a great value for the price.

We've tried both the original and a very good knock-off which was actually a little better, but this one is by far the best performing. This cleans our air far better than other compatible filters, at a bargain price. We are very fussy and insist on top performance and this is the one we'll be getting from now on. If you're looking for a great replacement filter for these machines, you have found it.

Whirlpool 1183054 and their filters are the best air cleaning system for my need.

Worked as expected. Perfect fit and is working fine after a few weeks. Note, other reviews mentioned the smell of glue. I noticed a bit of a smell (not sure glue, maybe like a rubber or something) but that went away after a few days and not noticeable at all. I seemed to recall the original whirlpool may have the same "new" smell anyway, so not a worry.
