156 owner reviews, fewer than most models here
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 WD-F26B is a refrigerator replacement filter from Waterdrop sold in a 3-pack at $30.35, putting the per-filter cost around $10. The certification covers NSF 42, which addresses aesthetic impurities like chlorine taste and odor, and NSF 372, which verifies the unit is manufactured from lead-free materials.
At 7.48 x 2.6 x 9.45 inches and 10.56 pounds for the pack, it is a standard-sized cartridge. The 4.7 rating from 156 reviewers indicates a high approval rate, though the review base is relatively small compared to some competitors in the Waterdrop lineup.
Buyers looking for a straightforward drop-in filter that meets baseline NSF material and taste standards will find this a workable pick. Those needing certified reduction of heavy metals or pharmaceuticals should look at filters carrying NSF 53 or NSF 401 certification instead.

Performance notes
The WD-F26B is certified to NSF 42, meaning it is designed to reduce aesthetic impurities such as chlorine taste, odor, and particulates that affect water appearance. NSF 372 certification verifies that contact materials meet lead-free standards. No purification method or gallons-per-filter capacity figure is listed in the available specifications, so buyers should confirm replacement intervals with the refrigerator manufacturer or Waterdrop directly.
What buyers say
With 156 reviews and a 4.7 rating, buyer feedback skews strongly positive. The volume is moderate rather than high, so the score reflects a consistent but not yet broadly validated experience. No unusual complaint patterns stand out from the available data.

Frequently asked questions
What does NSF 42 certification mean for this filter?
NSF 42 certification means the filter has been tested and verified to reduce aesthetic impurities, primarily chlorine taste, odor, and related compounds that affect the smell and flavor of tap water. It does not cover reduction of heavy metals, cysts, or pharmaceuticals. If you need coverage for those contaminants, look for a filter also certified to NSF 53 or NSF 401.
What does NSF 372 mean on the WD-F26B?
NSF 372 is a certification for drinking water system components that verifies the product is manufactured from lead-free materials, complying with U.S. federal and state drinking water regulations. It addresses the construction of the filter itself rather than what the filter removes from water.
How many filters come in one order?
One purchase of the WD-F26B includes 3 filters, making the per-unit cost approximately $10 at the listed price of $30.35. Having extras on hand means you can swap the filter on schedule without waiting for a new order to arrive. Confirm your refrigerator model compatibility with Waterdrop before ordering.
