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.

Overview
The Waterdrop UKF8001 replacement targets one of the most widely used refrigerator filter footprints, which is the UKF8001 form factor found across many Maytag, Whirlpool, and Amana models. That broad compatibility is likely a major driver behind its 9,500 buyer reviews, which is a notably large sample for a model-specific filter.
NSF 42 and NSF 372 certifications are present. NSF 42 means the filter has been independently tested for reduction of chlorine taste and odor. NSF 372 confirms lead-free materials in the wetted components. The filter measures 7.09 x 2.36 x 8.07 inches and weighs 1.88 lb, which aligns with the standard UKF8001 housing dimensions.
At $26.99 for three, the per-filter cost is approximately $9. That positions this well below OEM pricing for the same filter footprint, which typically runs $25 to $50 per unit. Combined with the 4.8-star rating across nearly 10,000 reviews, it represents a strong value proposition for compatible refrigerator owners.
Pros
- NSF 42 and NSF 372 dual certification
- 9,500 reviews at 4.8 stars provides very high confidence

Cons
- NSF 42/372 does not cover health-concern contaminants such as lead in source water
- No gallons-per-filter capacity is listed
- Some refrigerators may require a manual filter indicator reset after installation

Frequently asked questions
Which refrigerators are compatible with the Waterdrop UKF8001?
The UKF8001 footprint is used in a large number of Maytag, Whirlpool, Amana, and Jenn-Air side-by-side and French door refrigerators. Check your refrigerator model number against the Waterdrop compatibility list before ordering, as some models use visually similar but physically different filter cartridges.
How does this compare in price to the OEM Maytag UKF8001 filter?
OEM Maytag UKF8001 filters typically sell for $30 to $50 per unit at major retailers. The Waterdrop three-pack at $26.99 brings the per-filter cost to roughly $9, representing a savings of $20 to $40 per filter compared to OEM. That savings compounds quickly for households that change filters every six months.
Does NSF 42 certification mean this filter reduces lead?
No. NSF 42 covers reduction of aesthetic impurities like chlorine taste and odor. Lead reduction requires NSF 53 certification specifically. NSF 372, which this filter also carries, only confirms the filter's own construction materials are lead-free. If lead in your source water is a concern, look for a filter certified to NSF 53 for lead reduction.
