The manufacturer behind cleaner shower water
Zooshen designs and manufactures shower water filters that remove chlorine and improve bathing water. Founded in 2019 and headquartered in Shenzhen, China, we operate a single 12,000 m² manufacturing facility with an annual capacity of 2.4 million units and export to more than 40 markets — backed by ISO 9001:2015 and NSF/ANSI 177 certification.
Overview: what Zooshen does
Zooshen is a dedicated shower water filter manufacturer - not a trading company. We engineer, test, and produce complete shower filtration systems in our own factories so that wholesale buyers get consistent quality, real certifications, and dependable supply.
Shower filters are the simplest upgrade most households never make: a compact cartridge fitted inline or inside a showerhead that removes chlorine and other impurities from bathing water. Zooshen manufactures the full range - inline shower filters, filtered showerheads, handheld filters, and replacement cartridges - so there is a product for every plumbing setup and market.
Because we control manufacturing directly, we can offer private label and wholesale programs with reliable MOQs and repeatable quality - the two things commercial buyers need most from a factory partner.
- Founded in 2019 in Shenzhen, China
- Single owned factory in Shenzhen, approx. 12,000 m² plant area
- Annual capacity of 2.4 million units
- ISO 9001:2015 quality system; NSF/ANSI 177 certified
- KDF-55 filtration media across core products
- 60+ staff, including 9 R&D engineers
Why Zooshen exists
Most people never think about what is in their shower water. Municipal chlorine - added to keep drinking water safe - also strips moisture from skin and hair during every shower. Zooshen exists to make better bathing water affordable and easy: a shower filter that installs in minutes, removes chlorine effectively, and is honest about what it does and does not do.
That honesty extends to every claim on this site. Where we state a certification, it is earned. Where we state performance, it is tested. See Standards & Certifications for the current status of every claim.
Mission & values: how we operate
Four principles guide every product decision at Zooshen. They sound simple; they are the hardest part of manufacturing honestly.
We do not claim our filters turn shower water into mineral water. We publish what our products remove, what they are certified for, and what they cannot do. Buyers can compare us against competitors and trust the comparison.
Claims on this site are backed by our NSF/ANSI 177 certification, ISO 9001:2015 quality system, and documented test methods. If a claim is not verifiable, it does not go on the page.
Filtration media and cartridge housings are engineered for repeat use, with replacement cartridges designed to extend product life rather than force frequent replacements.
Shower filtration is full of confusing chemistry. Our Learn library explains chlorine, KDF-55, flow rates, and cartridge life in plain language, so buyers can make informed decisions.
The result for our partners
These values matter commercially. When you source from Zooshen, you sell a product backed by real certification, consistent manufacturing, and documentation you can show your own customers. That is why more than 60 brands, hotels, spas, and retailers already stock Zooshen products across 40+ markets.
