Malaysia Water Purification Base
HisoAir's water purification partner Mona brings 28 years of industry experience to a Malaysian production base in operation since March 2026. Filters and control electronics are developed in-house by the group, mass-production testing matches its Shaoxing headquarters, and country of origin is confirmed in writing for each program.

Why This Facility
Johor Bahru sits about 15 minutes from the Singapore border, with Senai Airport and Singapore Changi both within an hour. For water purification brands, it offers a non-China production option backed by a group with its own filter and electronics capability.
Non-China Origin for Water Programs
A Malaysian production base in operation since March 2026, giving North American and European brands an alternative country of origin for countertop RO platforms. Origin is assessed per product and confirmed in writing before shipment.
Core Components Under Group Control
Mona develops and manufactures its own filter cartridges and PCBA control boards. The components that determine water quality and product safety are not sourced from an outside vendor.
Capacity Ready Without New Construction
Production lines are running with capacity available for new programs today. Two adjacent standard buildings can add 8,000 m², with expansion from fit-out to line commissioning planned within about four months.
Headquarters-Level Testing On Site
Mass-production testing at the Malaysia base matches the group's Shaoxing plant, so a Malaysia-built unit is released against the same criteria as its China-built equivalent.
Core Capabilities
This facility's contribution to the HisoAir network is healthy-water production outside China — clean assembly, group-controlled core components, and North American certification experience.

Clean Assembly Environment
Production areas built toward cleanroom standards, with all water-contact injection parts moulded in a clean injection workshop.

Standardized Production Lines
Two standardized lines covering pre-assembly, assembly, testing and packaging under documented operating procedures.

In-House Filter & PCBA Development
Filter cartridges and control electronics developed and produced within the group, securing the components that define water quality and safety.


Full-Scope Reliability Testing
Functional, aging, environmental, noise, transport simulation, drop, high- and low-temperature operation and water hammer testing.

North American Certification Experience
Hands-on experience securing NSF/ANSI certification through CSA, NSF and WQA, including NSF/ANSI 58 for reverse osmosis and NSF/ANSI 372 for lead content.
Products & Manufacturing Support
This facility supports the Water pillar of HisoAir's Indoor Health Framework — Healthy Water — with countertop platforms built for installation-free use.
Countertop RO Purifiers — Instant Hot
Installation-free countertop reverse osmosis platforms with mineralized multi-stage filtration, instant heating and stepless temperature and volume control.
Countertop RO Purifiers — Hot & Cold
Countertop RO platforms adding compressor or electronic cooling to instant heating, delivering chilled, ambient and hot purified water from one unit.
Quality, Verification & E-E-A-T
For drinking water products, certification is where market access is won or lost. We document it per program, per facility, per model.
Standard Quality Control Process
NSF/ANSI and other drinking water certifications are issued to a specific certificate holder, model and manufacturing location; they do not transfer automatically between models, facilities or brands. Certification status for a given program is confirmed in writing before production. Shipment from Malaysia does not by itself establish Malaysian country of origin; origin is determined per product under the rules of the destination market, based on the bill of materials and the transformation performed at this facility. HisoAir does not provide customs or legal advice and recommends customers confirm classification and duty treatment with their own broker or counsel.
