NSF/ANSI 177 certified shower filters, checked against NSF's listing
Last reviewed 2026-10-16.
Two US-brand shower filters are on NSF's NSF/ANSI 177 listing: the Jolie Filtered Showerhead from Jolie Skin Company and the Weddell Duo (WD-100) from Weddell Water. Both are certified for free available chlorine reduction, the one claim the standard has. The Aquabliss SF100 is not on the listing.
Checked on 2026-10-16 in NSF International listing, NSF/ANSI 177 (https://info.nsf.org/Certified/DWTU/Listings.asp?Standard=177), which lists 7 makers and 11 products. Amazon offers read on 2026-10-16 for a US address.
NSF/ANSI 177 has one claim: free available chlorine reduction. A listing does not cover any other effect, and these pages make no other claim for any filter.

| Shower filter | Company on NSF's listing | Replacement element | Service cycle (NSF) | Certified claim | Buy |
|---|---|---|---|---|---|
| Jolie Filtered Showerhead | Jolie Skin Company, Inc. (Accord, NY) | Jolie Replacement Filter | not quoted (see the note below) | free available chlorine reduction | Amazon ↗ |
| Weddell Duo (WD-100) | Weddell Water (Irvine, CA) | WD-100F | 10,000 gallons per WD-100F filter, at 2 gpm | free available chlorine reduction | Amazon ↗ |
Listed alphabetically, not ranked: both hold the same single claim. The service cycle is the volume NSF lists for one replacement element. For the Jolie: NSF's table prints 1.4 in the service-cycle (gallons) column and 2400 in the flow-rate (gpm) column for this product. A 1.4-gallon service cycle and a 2,400 gpm flow rate are not possible, so this page does not quote a capacity or flow rate for it. Prices are not shown; check the listing for the current price.
How each product was matched to the listing
- Jolie Filtered Showerhead: NSF lists the product by trade name, The Jolie Filtered Showerhead, with no model number. The Amazon listing has the same name, brand Jolie Skin Company, and is sold by Jolie Skin Company, the company on NSF's listing. NSF also certifies it to NSF/ANSI/CAN 372, which covers the lead content of the materials, not what the filter removes from water.
- Weddell Duo (WD-100): The Amazon listing's item model number, WD-100BL, is the black colour of the Weddell Duo (WD-100) on NSF's listing. This page links the black WD-100BL only. NSF lists three colours: WD-100BL (black), WD-100WH (white), WD-100PN (pink).
The other makers on NSF's listing are Amway Japan G.K.; ATGENE Inc.; Coconutfilter; Seongill Chemical Co., Ltd; UBS Inc. Co., Ltd. Their products are not linked here: we did not match them to a US Amazon listing.

We do not test filters — we index what accredited certifiers publish, with attribution, and make no health or treatment claims. A certification covers a specific model against a specific standard; it is not a general seal of quality. We are not affiliated with NSF International.
