Hard water is a real headache for many of us living up north in Chiang Mai. Chalky spots on your glasses or skin feeling extra dry after a shower can get pretty annoying over time. 

That’s where finding the best water softener in Chiang Mai comes in. With the right system, you can protect your home appliances and even enjoy softer hair and skin after every wash. 

We put this guide together to help you choose a water softener that actually makes a difference in your daily routine. Let’s check out some solid options that can finally solve those hard water problems for good!

1. HomePro Chiangmai Hangdong

Website: https://www.homepro.co.th/

Address: 433/4-5 หมู่ที่ 7 Chiang Mai, Mae Hia, Mueang Chiang Mai District

Contact: +6652005959

Hours: Monday-Sunday, 8:30 AM – 9:00 PM

HomePro Chiangmai Hangdong carries several whole-house resin systems from popular brands like MEX and Mazuma that can help reduce water hardness in your home. 

If you have an old unit, you might even get a trade-in discount on select products. 

They offer free standard installation and will remove your old purifier when they deliver the new one, making the whole process easy. 

They even include an 180-day installation warranty and do post-installation testing right away. You’ll really get peace of mind knowing the setup is covered for months.

One customer mentioned they first heard about this team while searching for handyman services, and they appreciated how clear and upfront the pricing was when their system was installed.

Just keep in mind you might pay extra for things like additional pipes or electrical wires.

2. Global House Wiang Kum Kam

Website: https://globalhouse.co.th/

Address: 99, 3 Somphot Chiang Mai 700 Pi Rd, Tha Wang Tan, Saraphi District

Contact: [email protected] | Call Center 1160 | +66922477504

Hours: Monday-Sunday, 7:30 AM – 8:00 PM

Global House Wiang Kum Kam is known for their modern warehouse style, so you can check out all the building materials and decorative items for yourself at your own pace. 

Their water system section has a special MEX softener with an automatic resin regeneration cycle. This means you won’t have to worry about cleaning the media or salt tank by hand. 

The model holds 100 liters and can filter lots of water each hour, too, making it a solid pick for bigger homes or small offices. 

You can have their professional team install it, or if you’re picking up smaller plumbing items, there’s a simple click-and-collect option.

One thing to note is their softener has just a one-year warranty. 

3. Big C Supercenter Chiang Mai Don Chan

Website: http://www.bigc.co.th/

Address: 208, Tha Sala Sub-district, Mueang Chiang Mai District

Contact: +6653262355

Hours: Monday-Sunday, 8:00 AM – 9:00 PM

Shopping for house items is much better when you can knock out other errands simultaneously. Luckily, Big C Supercenter Chiang Mai Don Chan acts as a one-stop supercenter, combining a hypermarket with a food center, banks, and shops. 

And with five local branches, you’re never far from a refill, and ordering your resin online is quick since express delivery matches in-store prices and promos. 

Service-wise, their staff can help you choose Mazuma ion-exchange media, which are specifically made to tackle calcium and magnesium in your water.

A clear limitation is that their main listed machine is just a three-stage drinking unit. It isn’t a large whole-house softener designed to treat all incoming water. 

Still, they’re incredibly convenient for minor needs or grabbing quick supplies.

4. World Chemical

Website: https://www.worldchemical.co.th/

Address: 261/3-6 Rd. Mahidol T. Sun Forest A City E

Contact: 053-204-446 | 0-5320-4446-7 | [email protected]

Hours: Monday-Saturday, 8:00 AM – 5:00 PM

World Chemical has been around since 1995, so with over three decades of experience in chemical distribution, you really feel like you’re in good hands. 

A big part of what they do is focus on bulk options to help you save on overall costs, especially if you need a lot of material at once. You’ll find huge bags of ion-exchange resin, plus high-purity regeneration salt. 

Beyond that, you’ll also find activated carbon and manganese media for people needing more advanced water filtration.

The only real downside is that their main softening cartridge for homes only lasts six to twelve months. This means you’ll need to plan on swapping it out regularly instead of expecting a permanent fix.

5. หจก.ซีเอ็มวอเตอร์เทค | CM Watertech
