556 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 ADQ36006101 carries certification to NSF 42, 53, 401 and 372. NSF 42 covers aesthetic contaminants such as chlorine taste and odor, NSF 53 addresses certain health-related contaminants, and NSF 401 covers emerging compounds including pharmaceuticals and pesticides. NSF 372 confirms low-lead construction. That breadth of certification is notably more extensive than filters that carry only NSF 42.
The two-pack format at $32.99 puts each filter around $16.50, which is competitive for a filter with multi-standard certification. The compact form factor, measuring roughly 3.6 by 1.8 by 7.2 inches, is sized for in-door or in-grille refrigerator installation.
With 556 reviews and a 4.7 rating, the review base is moderate but the satisfaction signal is strong. Buyers have found fit and filtration performance consistent enough to return and rate highly.
Pros

- 4.7 star average across 556 reviews indicates consistent buyer satisfaction

What buyers say

Frequently asked questions
What contaminants is the Waterdrop ADQ36006101 certified to reduce?
It is certified to NSF 42 (aesthetic impurities including chlorine taste and odor), NSF 53 (select health-related contaminants), NSF 401 (emerging compounds such as pharmaceuticals and pesticides), and NSF 372 (low-lead construction). Always check current NSF certification listings for the full contaminant list covered under each standard.
How long does each filter last?
The manufacturer does not publish a specific gallon capacity for this filter. Most refrigerator filters are designed for roughly six months of use under average household consumption, but actual life depends on water quality and usage volume. Follow the replacement reminder on your refrigerator and replace sooner if you notice taste or odor changes.
Is the ADQ36006101 safe regarding lead?
The filter carries NSF 372 certification, which confirms that the materials used in construction meet low-lead requirements. This is separate from any claim about reducing lead in your water supply. If lead in your water source is a concern, look for a filter additionally certified to NSF 53 for lead reduction and verify that specific contaminant appears on the certification listing.
