5 Best Water Treatment Systems in Vietnam if You’re looking for Water Softeners
If you’ve ever looked at your faucet in Vietnam and wondered why it’s covered in a crusty white layer, you’re not alone.
I used to think my skin was just naturally turning into sandpaper until I realized the culprit was flowing right out of my showerhead.
In some parts of Vietnam (especially where homes rely on groundwater), hard water and mineral buildup are common, and certain regions have documented arsenic risks
After scrubbing enough limescale to lose my mind (and my manicure), I decided to find a permanent solution. I wanted a system that would actually protect my health and my home, rather than just a machine taking up space.
So, I dug into the market to find the providers that deliver on their promises.
Here are the best water softeners in Vietnam that stood up to our research on tech, durability, and service.
How much do water softeners cost in Vietnam?
Costs vary heavily depending on your specific needs. If you are looking for a basic manual valve to fix up a Do-It-Yourself (DIY) system, you might only spend around 150,000 to 250,000 VND. However, for a fully automated residential setup or a system robust enough for a busy commercial kitchen, you should expect to pay thousands of dong.
1. HOA PHAT ECO INDUSTRIAL SOLUTION AND ENVIRONMENTAL TECHNOLOGY JSC
Website: https://hoaphat-eco.com/en/solutions-services/water-treatment/
Address: No.18, Street 2, Van Phuc Urban area, Hiep Binh Phuoc Ward, Thu Duc City, Ho Chi Minh City
Contact: 028 6682 2579 | 0906 903 987 | [email protected]
Hours: Mon-Sat 8:00 AM – 6:00 PM
Hoa Phat Eco is a strong option for anyone needing high-tech, automated water treatment.
Rather than just selling you a machine, they act as a full-scale EPC (Engineering, Procurement, and Construction) contractor, handling your entire project from the initial design down to the final legal paperwork.
They’re known for advanced processes like nano-filtration and arsenic removal, and they easily customize setups for sensitive industries like food or pharma.
Plus, their ability to design large-scale, automated water softening systems makes them perfect for industrial boilers and cooling towers that need strict mineral control.
Just keep in mind that they are strictly a B2B, project-based company. If you’re hunting for a simple under-sink filter for your apartment, you’ll need to look elsewhere.
But if you’re a factory owner needing a reliable system, their backing by the Hoa Phat Group offers some serious long-term peace of mind.
2. XNK MÁY LỌC NƯỚC ĐÀI VIỆT (Dai Viet Company)
Website: http://daivietprotech.com.vn/
Address: 67, Street 16, Cat Lai Ward, Ho Chi Minh City
Contact: 1900 636 509 | 0903 331 339 | [email protected]
Hours: Mon-Sat 7:30 AM – 5:00 PM
If you’re looking to start a water brand or need heavy-duty filtration, Dai Viet Protech goes way beyond basic setups.
Since 2006, they’ve built a solid reputation for installing complete bottling lines and even medical-grade dialysis systems for hospitals.
What really stands out is their quality control. Instead of relying on generics, they import key components directly from Taiwan, Korea, and the US.
They are especially known for effectively treating notoriously difficult water sources in the Mekong Delta using advanced reverse osmosis. Handling these tough conditions so consistently has made them the go-to water treatment partner for major commercial facilities in the region.
There is a small catch, though. Because their support team is highly centralized, you might experience slower maintenance response times if your business is out in a remote province compared to being in a major city hub.
3. Waterco Vietnam Company Limited
Website: https://www.watercovietnam.com/
Address: Apt no.00.20, Ground Floor, Thu Thiem Lake View 1 Condominium – No. 19 to Huu Street, Thu Thiem Ward, Thu Duc City, Ho Chi Minh City
Contact: 028 3622 7780 | [email protected]
Hours: Mon-Fri 8:30 AM – 5:30 PM
With over 40 years of experience and a spot on the Australian Securities Exchange, Waterco Vietnam’s reputation speaks for itself.
I actually stopped by their Thu Duc office recently to check out the units in person. I remember knocking on a filter tank in there, and it felt incredibly thick and solid, which was a huge step up from the flimsy plastic you get with cheaper models.
Plus, their specialized internal piping ensures even water flow through the filter bed, making them highly efficient.
It’s reassuring to know they have a corporate team right here in HCMC for warranty support. But be prepared to open your wallet. They’re a premium provider, so the upfront investment is noticeably steeper than standard mass-market brands.
Nevertheless, they’re a reliable choice if you want established reliability for anything from residential pools to commercial water treatment.

4. Mitsubishi Cleansui Vietnam
Website: http://mitsubishicleansui.vn/
Address: 12 Hoang Trong Mau Street, Tan Hung Ward, Ho Chi Minh City
Contact: 1800 8171
Hours:
- Mon-Fri 8:00 AM – 5:00 PM
- Sat 8:00 AM – 12:00 PM
The Mitsubishi Cleansui is a fantastic option when it comes to under-sink water filters. For anyone living in a tight apartment, its compact design is highly practical. You don’t need a massive tank or even electricity to run these units under your sink.
Unlike bulky Reverse Osmosis systems that strip your water completely bare, this compact unit doesn’t need a massive tank or any electricity to run.
Instead, it uses dense fiber membranes to sift out the bad stuff while leaving healthy minerals (like calcium and magnesium) perfectly intact. The result is crisp, natural-tasting water from hardware that is 100% made in Japan.
However, their ongoing maintenance costs are one catch to keep in mind.
While the initial setup is sleek and highly practical, you’ll need to budget carefully for the replacement cartridges. They have to be swapped out annually and are noticeably pricier than standard sediment filters.
Customer Reviews
The service is really good
My family has been using the machine for more than a year, I must say the service is really good, the support staff are very enthusiastic, the after-sales service is also very good, the goods are imported from Mitsubishi Japan so the quality is worth the price. I have acid reflux, using alkaline ionized water from Cleansui machine, I feel completely cured, my skin is also more beautiful.

I feel more secure
The sales person is enthusiastic. The item is small, I’m busy so I don’t have much time. My house is also near the sales person’s company, so he came to my house to help me install that small model and give me more advice. I’m planning to install an additional kitchen area. The goods are imported from Japan so I feel more secure. I think the service is very good, everyone. After the house renovation, I bought an alkaline ionizer for the kitchen.

5. Song Phung Water Equipment
Website: https://filter.vn/
Address: 11A Ly Dao Thanh Street, Phu Dinh Ward, Ho Chi Minh City
Contact: 0913 907 274 | 0984 620 494
Hours:
- Mon-Friday: 8:00 AM – 5:00 PM
- Sat 8:00 AM – 12:00 AM
For B2B buyer or an experienced DIYer, Song Phung can be a solid choice. This is because they prioritize speed and carry a massive inventory of over 18,000 items ready for immediate fulfillment.
Because they’re a major distributor for top global brands like Runxin and Clack, you never have to worry about cheap knock-offs. You’re pretty sure that you’re getting genuine parts.
Another huge perk is their fast turnaround time. Their team can actually design a custom system for you in under 24 hours!
That said, Song Phung is definitely geared toward people who already know their stuff. If you’re just looking for a simple, plug-and-play appliance and have no idea what a control valve is, navigating their massive catalog will likely feel overwhelming.
The selection process can also get complex pretty quickly, so it’s best suited for those with a solid baseline of technical knowledge.
