262 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 WDP-F22 sells as a single filter at $19.99. That per-filter price is moderate for an NSF-certified aftermarket refrigerator filter sold individually. For households that replace filters once a year rather than every six months, buying one at a time may be preferable to stocking a 3-pack.', 'The available specs do not list dimensions, weight, capacity, or compatible refrigerator models. The NSF certification is noted without a specific standard number. That absence of detail makes it harder to compare directly against competitors or confirm fit without external research.', 'With 262 ratings and a 4.6-star average, the review pool is smaller than many competing Waterdrop models but still meaningful. A 4.6 score from 262 buyers suggests the product generally delivers on its core promise without widespread fit or performance complaints.']

Performance notes
The WDP-F22 is listed with NSF certification but without a specific standard designation such as NSF 42, 53, or 401. This means the scope of certified performance, whether it covers taste and odor only or extends to health-effects contaminants, cannot be confirmed from the available data. No filter capacity or rated service life is listed. No dimensions are provided, which limits the ability to assess physical fit from specs alone.
What buyers say
At 4.6 stars from 262 reviews, buyer sentiment for the WDP-F22 is positive. The review count is on the lower side for a Waterdrop product, which may simply reflect a narrower compatibility range. The score itself is consistent with a product that works as intended for a specific set of refrigerator owners.

Frequently asked questions
What NSF standard does the WDP-F22 meet?
The WDP-F22 carries NSF certification per the listed product data, but the specific standard number is not provided in the available specs. NSF 42 covers chlorine taste and odor, and NSF 53 adds health-effects contaminant reduction. For the exact certification scope, refer to Waterdrop's product documentation or contact their support directly.
Why would someone buy a single filter instead of a 3-pack?
Single-pack filters make sense when you are trying a new aftermarket brand for the first time and want to confirm fit and performance before committing to a multi-pack purchase. They also work for households where refrigerator usage is low enough that a six-month replacement cycle means buying only one or two filters per year.
How do I know if the WDP-F22 fits my refrigerator?
No compatible model list is included in the product specs available here. The best approach is to locate the part number printed on your current filter cartridge and compare it to Waterdrop's compatibility information on the product listing page. You can also check your refrigerator's owner manual for the OEM filter model number.
