The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other water filtration: replacement filters, under-sink and reverse osmosis systems, filter pitchers, water dispensers, coolers, faucet filters and softeners we track in this category on price, popularity and size. Context, not marks against it, and our read of the data, not a lab test.
Overview
The Waterdrop WDP-F26A carries certification to NSF 42, 53, 401 and 372. The NSF 42 certification addresses chlorine taste and odor and other aesthetic impurities. NSF 53 covers select health-related contaminants. NSF 401 addresses emerging trace compounds. NSF 372 verifies low-lead materials. Taken together, this is one of the more complete certification profiles available on a mainstream replacement refrigerator filter.
The three-pack at $37.99 works out to roughly $12.66 per filter, which is a competitive price for this level of certification. The filter measures 7.48 x 2.6 x 9.45 inches and weighs 1.3 pounds, which is a common in-door or in-grille form factor for side-by-side refrigerators.
Buyers have left 513 reviews with a 4.7 average. That review count is on the smaller side compared to some Waterdrop models, but the high average rating is consistent with the brand's other well-certified offerings.

Frequently asked questions
Does the WDP-F26A reduce lead in drinking water?
The NSF 372 certification on this filter confirms that its construction materials meet low-lead requirements. If you need a filter certified to reduce lead in your water supply, you should specifically look for NSF 53 certification with lead listed as a covered contaminant, and verify the current NSF certification listing for this model at nsf.org. Questions about your home's water quality are best answered by a certified water test.
How does the WDP-F26A compare to filters with only NSF 42 certification?
NSF 42 covers aesthetic contaminants like chlorine taste, odor and particulates. The WDP-F26A adds NSF 53, which addresses select health-related contaminants, and NSF 401, which covers emerging trace compounds including certain pharmaceuticals and pesticides. That gives you broader coverage than an NSF 42-only filter, though the specific contaminants covered under each standard should be confirmed in the NSF certification listing.
Is a three-pack worth it for one refrigerator?
Most households replace refrigerator filters every six months. A three-pack covers about 18 months of use for a single refrigerator, and the per-filter cost at $12.66 is lower than buying one at a time. If you have multiple refrigerators or want to stock up to avoid running out, the three-pack is a practical choice. Filters should be stored in a cool, dry place before use.
