Purewell is a water-filtration brand registered in Hong Kong. It sells mainly online, and RV Parts Giant carries its 5-stage water filter straw. Here's what the brand makes, how to read its claims, and where its products make sense for RV owners.
What Purewell makes
- Countertop stainless gravity filter systems
- Under-sink filters and countertop reverse-osmosis (RO) units
- Outdoor gear: pump filters, filter bottles and personal filter straws
- Replacement filters for its systems

How to read Purewell's certification claims
Purewell's listings mention several third-party labs and standards. They don't all mean the same thing:
| Claim | What it means |
|---|---|
| SGS / TÜV | Independent testing labs. A report from either shows a product was tested, but you need the report itself to see what was tested and the results. |
| "Tested to meet NSF/ANSI 42" | Standard 42 covers aesthetic effects, such as reducing chlorine taste and odor. It isn't a claim about bacteria or viruses. |
| "Tested to meet NSF/ANSI 372" | Standard 372 covers lead content in the product's own materials, not lead removal from water. |
| "NSF certified" | Means the product is listed in NSF's public certification database. "Tested to" an NSF standard is not the same as NSF certification. Check the listing. |
This isn't a knock on Purewell; many filter brands word their claims the same way. Know the difference when you compare brands.
Is the Purewell straw a good pick?
For a go-bag or RV emergency kit, it's a reasonable choice:
- Five stages, including coconut-shell carbon, so it improves taste as well as filtering out bacteria and parasites through its hollow-fiber membrane.
- Light and simple: no pump, bottle or power.
- Limits to know: like every filter straw, it doesn't remove viruses or chemicals (CDC guidance), and it serves one person at a time. Pair it with Aquatabs, and use a gravity bag for a group.
Purewell's own listings quote different capacity figures for different straw versions, so check the rating printed on the box you receive.
Bottom line
Purewell is a mainstream online filter brand with a wide range, and its straw does the job a straw should. Read its certification wording carefully, and plan your water kit around what filters can and can't do.
