New filters from Aug-Sep 2026: none yet confirmed in a certifier listing
Are the newest water filters from Waterdrop, iSpring and AquaTru certified?
Waterdrop, iSpring, AquaTru, Frizzlife and LifeStraw listed new filters between August 4 and September 27, 2026; as of October 23 we had not confirmed any of them in an NSF, WQA, IAPMO or CSA listing.
LifeStraw listed the plastic Home Essential pitcher (7- and 10-cup) on 2026-08-04. The brand says it is 'rigorously tested' and names no certifier.
Waterdrop listed the M6CG hot-and-cold countertop RO ($539) on 2026-08-20 and the M6HG instant-hot countertop RO ($429) on 2026-09-02. The M6HG page says 'NSF/ANSI 58 & 372 certified'; we have not yet matched that to a certifier listing.
iSpring listed the WRO4000 whole-house RO ($8,999.99) on 2026-09-17, and the RO10001F tankless RO ($579.99) and US31KF direct-connect under-sink series ($110.99-$160.99) on 2026-09-18. The US31KF titles say 'NSF/ANSI compliant', which is brand wording, not a certification.
AquaTru's second-generation Under Sink RO ($395-$420), announced 2026-06-16, has been listed since 2026-09-23; the brand cites certification for 84 contaminants, which we have not yet confirmed. Frizzlife listed the M800 WiFi tankless RO ($349.99) on 2026-09-27; its page claims NSF/ANSI 58 and 372, but we found no NSF/ANSI 58 listing for it.
Certifier listings often appear after launch. Until they do, we treat these claims as brand-tested and point to the closest certified model on sale.
