About PureSipSpring
PureSipSpring exists because of one sentence that keeps appearing on product listings: reduces 50+ impurities. It is not a standard. It has no list, no protocol and no certifier behind it, and it sits comfortably next to sentences that do. Telling those two kinds of sentence apart is the entire job of this site.
Everything here comes from two places. The first is the text of a product listing, which is repeated as a listing statement and never upgraded into a fact. The second is a published standard, described by its scope and linked to a source you can check. 54 listings, 5 standards pages, 9 cartridge codes and 30 vessels with a stated volume.
There is no testing here. Nothing was filled, timed, dropped, driven around or measured. That claim is the easiest lie in this category, and the sites that make it rarely publish a method. This one does not make it.
The rules this site writes under
Certification comes from the listing, never from the shape of the box
If a listing names NSF/ANSI 42 and nothing else, this site shows one filled cell and two empty ones. It does not promote a cartridge to 53 because a similar cartridge holds 53.
Seller claims are labeled as seller claims
Reduces 50+ impurities, 99% microplastics, cold for 24 hours, leakproof, BPA-free. Every one of those appears here as something a listing states, not as something that is true.
There is no testing here and never was
Nothing on this site was measured, timed, filled, dropped or driven around. Claiming otherwise is the easiest lie in this category and the one this site refuses.
No health claims, on any page
Standards are described by their scope. What lead, PFAS or microplastics do to a person is a medical and toxicological question, and the EPA, the CDC and a clinician are the places for it.
No advice on how much to drink
Not in ounces, not by body weight, not eight glasses. The tools accept a volume you supply and say plainly that the number is yours.
Genuine and aftermarket are kept apart everywhere
On every model page, in every table, in the finder. Sometimes the aftermarket listing names a standard the genuine one does not, and that is shown too.
What this site is not for
No filter in this catalog makes unsafe water drinkable. Household drinking water filters are designed for water that is already fit to drink. They are not intended for microbiologically unsafe water and they do not replace a boil water advisory from your utility or health department.
This site does not tell anyone how much water to drink. Intake depends on the person, the climate and their health, and drinking too much water carries its own risks. Any volume you type into the tools on this site is your own figure.
There are no medical claims anywhere on this site. What lead, PFAS or microplastics do to a person is a medical and toxicological question, and a catalog of water bottles is not qualified to answer it. The pages that touch those substances describe the scope of a standard and then point at the EPA, the CDC and your local health department.
Corrections
Listings change. A cartridge that named three standard numbers in 2026 may name two next year, and when that happens the page here is simply wrong until it is fixed. If you find one, the fastest route is Contact, and a link to the listing is worth more than a description of it.
