Overview
A 3-pack of NSF/ANSI 401, 53, and 42 certified refrigerator water filters built as a replacement for the Whirlpool 4396510 and EveryDrop Filter 5, using the same coconut shell carbon block as Waterdrop's other filters.
This is the Filter 5 family specifically, covering a long list of Whirlpool, Kenmore, and EveryDrop part numbers, so matching the exact filter number rather than just the brand name determines fit. The NSF/ANSI 401 certification adds reduction claims for substances like BPA and ibuprofen on top of the standard 53/42 heavy-metal and taste-and-odor certification.
- 3-pack, NSF/ANSI 401, 53, and 42 certified
- Coconut shell carbon block filtration
- Replaces the discontinued Whirlpool Filter 5 / EveryDrop Filter 5
- Rated for 6 months or 300 gallons per filter
Who it's for
Owners of older Whirlpool or Kenmore side-by-side refrigerators that originally took the now-discontinued Filter 5, looking for a certified, lower-cost 3-pack alternative. Not the right filter for anyone whose fridge calls for Filter 4 or another number in the lineup.
What buyers say
From Amazon customer reviews.
Reviewers installing this in older Whirlpool side-by-side refrigerators report the fit is proper with no leaks and better-tasting water, and several call out the price as a fraction of a single branded filter. One buyer noted a slight lingering taste but attributed it to their aging refrigerator rather than the filter itself.
Strengths and trade-offs
Drawn from this product's published specifications.
- Certified against NSF/ANSI 401, 53, and 42
- Fits models whose original Whirlpool filter is discontinued
- Noticeably cheaper than buying a single branded filter
- Not interchangeable with other Waterdrop filter numbers
- One reviewer noticed a slight lingering taste
Performance notes
The coconut shell carbon block is rated to reduce a broad list of contaminants tested against NSF/ANSI 401 and 53, and Waterdrop notes it can also reduce PFOA and PFOS based on its own testing. Reviewers installing it in older side-by-side units report a proper fit with no leaking and no noticeable drop in flow, and one buyer specifically bought it because the original Whirlpool filter had been discontinued.

Questions about the Waterdrop WDP-F02
Common buyer questions answered straight from the product spec data - no fluff, no "it depends".
Does this filter work if my original Whirlpool Filter 5 is discontinued?
Yes, several reviewers specifically bought this as a replacement after their original Whirlpool filter was discontinued and report a proper fit.
Is this the same filter as Waterdrop's Filter 4 replacement?
No, this is the Filter 5 family (replacing Whirlpool 4396510 and EveryDrop Filter 5); it uses a different part number than Waterdrop's Filter 4 product.
How often should the filter be replaced?
It is rated for 6 months or 300 gallons, whichever comes first, and the pack includes install-date stickers to help track that.
