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 WD-F46 is a third-party refrigerator water filter from Waterdrop, certified to NSF 42, which covers aesthetic impurities. The six-pack format means you can stock up and cut the cost per replacement significantly compared to buying single filters. At $24.19 for six, the per-unit math is hard to argue with.
With 17,800 ratings averaging 4.6 out of 5, this is one of the more broadly reviewed filters in its class. That volume of feedback is a meaningful signal that it fits a wide range of compatible refrigerator models without frequent fitment complaints.
The filter is made from a material described as 'Water Filter' in specs, which is not especially informative, but the NSF 42 certification is the real credential here. Dimensions run 5.71 by 3.54 by 7.09 inches, and the filter weighs 1.2 lb. Lead-free construction is noted in the product listing.

Performance notes
This filter carries NSF 42 certification, meaning it is certified to reduce aesthetic impurities such as chlorine taste and odor. No NSF 53 or NSF 401 certification is listed, so it should not be relied on for contaminant reduction beyond aesthetics. Dimensions of 5.71 x 3.54 x 7.09 inches and a 1.2 lb weight are consistent with a standard twist-in fridge filter format.
What buyers say
With over 17,800 reviews and a 4.6-star average, buyer response is strongly positive for a third-party filter at this price. That scale of feedback suggests consistent fit across compatible models. Occasional complaints tend to center on compatibility with specific refrigerator models, which is normal for third-party replacements.

Frequently asked questions
Is the Waterdrop WD-F46 NSF certified?
Yes, the WD-F46 is certified to NSF 42, which covers the reduction of aesthetic impurities like chlorine taste and odor. It does not carry NSF 53 or NSF 401 certifications. If you need certified reduction of contaminants such as lead or pharmaceuticals, look for a filter with those additional certifications.
How many filters come in the WD-F46 pack?
This listing includes six filters. At a price of around $24.19, that works out to roughly $4 per filter, which is significantly less than most OEM single-unit options. Buying in bulk like this makes sense if your refrigerator uses this filter format regularly.
How do I know if the WD-F46 fits my refrigerator?
The WD-F46 is a third-party filter designed to replace specific OEM fridge filters. Check your refrigerator model number and confirm it appears on the Waterdrop compatibility list before purchasing. If you are unsure, the product page typically lists compatible refrigerator models. Installing an incompatible filter can result in leaks or reduced flow.
