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 WDP-F07 comes in a 3-pack at $34.99, or roughly $11.67 per filter. What sets it apart from most aftermarket refrigerator filters is its triple NSF certification: 42, 53, and 401. NSF 42 covers taste and odor. NSF 53 certifies reduction of health-effects contaminants, and NSF 401 addresses emerging contaminants including certain pharmaceuticals and personal care product compounds. That breadth is uncommon at this price tier.', 'The dimensions are 7.09 x 2.36 x 8.07 inches and the pack weighs 1.9 lbs. This profile is consistent with a standard push-in refrigerator cartridge for common side-by-side and French-door models. No compatible model list is provided in the available specs, so verifying fit against your fridge part number is necessary before purchase.', 'Over 5,100 reviews averaging 4.7 stars makes the WDP-F07 one of the more thoroughly reviewed filters in this roundup. A 4.7 score at that volume is a strong signal of consistent performance and reliable fit across a wide install base.']

Performance notes
NSF 42 certification covers reduction of chlorine taste and odor and certain aesthetic impurities. NSF 53 certifies the filter is designed to reduce health-effects contaminants, which may include lead, cysts, and volatile organic compounds depending on the specific test protocol. NSF 401 covers emerging contaminants such as certain pharmaceuticals, hormones, and pesticide byproducts. The combination of all three is unusual in the under-$35 segment. Dimensions of 7.09 x 2.36 x 8.07 inches and 1.9 lb pack weight indicate a standard-profile push-in cartridge.

Frequently asked questions
What contaminants is the WDP-F07 certified to reduce?
The WDP-F07 is certified to NSF 42, 53, and 401. NSF 42 covers chlorine taste and odor reduction. NSF 53 certifies reduction of certain health-effects contaminants, which can include lead and cysts depending on the specific tested claims. NSF 401 covers emerging contaminants such as trace pharmaceuticals and personal care product compounds. For the complete list of specific contaminants covered, refer to Waterdrop's NSF certification documentation or contact [email protected].
How does NSF 401 certification differ from NSF 53?
NSF 53 covers regulated health-effects contaminants that have established EPA maximum contaminant levels, such as lead and cysts. NSF 401 was created specifically for emerging contaminants that do not yet have federal regulation but are increasingly detected in water supplies, including certain over-the-counter medications, personal care products, and some pesticide degradation products. A filter certified to both provides a wider range of potential coverage.
Does the 3-pack represent good value for a filter with these certifications?
At $34.99 for three filters, each filter costs about $11.67. Most filters certified to NSF 53 and 401 in the aftermarket segment tend to cost $12 to $20 each, so this pack pricing is on the lower end of that range. Whether it is good value depends on how often you replace filters and whether the wider certification scope addresses actual water quality concerns in your area.
