ASIN: B079ZMDLJVModel: WD-F03Category: Household Water Filters
Overview
The Waterdrop WD-F03 is a single replacement filter cartridge, NSF 42 and NSF 372 certified, sized at about 1.97 x 10.5 x 1.97 inches. It's a single-unit reorder rather than the multi-packs seen elsewhere in this batch, aimed at owners restocking one filter at a time.
With only NSF 42 and 372 certification, the WD-F03 is built around chlorine taste and odor reduction and lead-free construction rather than the broader emerging-contaminant coverage that filters carrying NSF 401 and 53 offer, so it's a narrower-scope filter by comparison.
- NSF 42 / NSF 372 certified
- 1.97 x 10.5 x 1.97 in cartridge
- Single-unit pack
- Chlorine taste and odor reduction certified
Who it's for
Buyers who need a single replacement cartridge sized 1.97 x 10.5 x 1.97 inches and only need taste and odor reduction, not broader NSF 401/53 contaminant coverage.
Pros and cons
- NSF 42 and NSF 372 certified
- Sold as a single unit for targeted reordering
- Narrower certification scope than filters carrying NSF 401/53
- No compatibility list for specific systems
Performance notes
NSF 42 certification confirms chlorine taste and odor reduction was independently tested, while NSF 372 confirms lead-free construction of the cartridge itself. Neither certification covers the wider contaminant list that NSF 401 or 53 would test for.

Frequently asked questions
How many filters come with the WD-F03?
One, unlike the three-packs common elsewhere in Waterdrop's lineup.
What does NSF 372 cover?
It confirms the cartridge is built without lead, a construction standard separate from the NSF 42 taste and odor reduction certification.
Will it fit my existing housing?
Check the 1.97 x 10.5 x 1.97 inch dimensions against your current cartridge; Waterdrop hasn't published a specific compatible-models list in this data.
