Waterdrop WD-RPWF Water Filter Review
Our verdict
The Waterdrop WD-RPWF is an NSF-certified two-pack refrigerator filter priced at $29.74 and available in a compact form factor at 3.74 x 1.97 x 9.84 inches. With 242 reviews and a 4.4-star rating, it has a smaller feedback base than many Waterdrop filters, so there is less certainty around long-term performance consistency.

242 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 Waterdrop WD-RPWF is a two-pack replacement filter rated at 4.4 stars from 242 buyer reviews. The NSF certification it carries indicates it has been evaluated by a third-party lab, though the specific NSF standard number is listed simply as 'NSF' without further breakdown.
At $29.74 for two filters, the per-unit cost is roughly $14.87, which is reasonable for a Waterdrop-branded NSF-certified filter. The physical dimensions of 3.74 x 1.97 x 9.84 inches give buyers a reference point when confirming it will fit their filter housing.
The 4.4-star average is lower than most other Waterdrop filters in this category, and the review count of 242 is modest. Buyers should read recent reviews carefully to check for any fit or flow-rate issues specific to their refrigerator model before committing to a purchase.

Performance notes
The filter lists NSF certification, which indicates third-party laboratory testing. Without a specific NSF standard number confirmed in the facts, the scope of that certification cannot be precisely stated. The filter is designed to reduce chlorine taste and odor as a minimum performance expectation for NSF-certified products. No capacity figure is available from the listing.
What buyers say
At 4.4 stars from 242 reviews, buyer satisfaction is acceptable but below the typical 4.6 to 4.8 range seen in this product category. The smaller review base means results may reflect a narrower sample of use cases. Buyers looking for high confidence may want to check a model with more reviews.

Frequently asked questions
Does the Waterdrop WD-RPWF include the full NSF certification number?
The listing notes NSF certification but does not detail which specific NSF standard. Common refrigerator filter certifications are NSF 42 for taste and odor and NSF 53 for health-concern contaminants. If your specific water quality concern matters, contact Waterdrop directly to confirm which standard the WD-RPWF is tested to.
How does the two-pack pricing compare to the OEM option?
At $29.74 for two filters, each comes to roughly $14.87. OEM refrigerator filters for compatible models often range from $30 to $60 per unit, so the Waterdrop two-pack offers a meaningful cost reduction if the filter fits correctly and performs to your expectations.
