Select Purchase Option:
Bath time should leave your baby's skin feeling soft and comfortable - not dry, itchy, or irritated. Arius helps create cleaner, softer bath water by reducing contaminants and softening hard water.
What makes Arius different: It combines a water filter and a true water softener in one system, reducing chlorine, heavy metals and other impurities while also softening the water. Works the same way as bulky whole house water softening and filtration systems packed in a compact and apartment friendly design.
A filter and a water softener fix different parts of the problem:
Filters remove chlorine, odors, and some heavy metals
→ This can help with hair and skin issues
→ But they don’t remove hard water minerals, so they don’t fix everything
Water softeners remove calcium and magnesium (what makes water “hard”)
→ These minerals cause buildup, dryness, and poor lather
→ Removing them is what makes the biggest difference you actually feel
Why this matters:
Hard water leaves a film on your hair and skin
That film makes hair feel rough and skin feel dry
It also makes soaps and shampoos work worse
Arius does both — it filters impurities and softens hard water for a more complete solution.
At Arius, we believe you should only pay for products that deliver on their promises.
If you don't notice a difference in your child's hair and skin within 60 days, simply return Arius for a full refund.
No hassle. No risk. Just better bath water thats guaranteed to make a difference.
There are a lot of bold claims and empty promises in online shopping, especially in the water filtration space. That's why Arius is independently lab tested to actually remove what it says it does.

Frequently Asked Questions
Do I need a plumber to install Arius?
Not at all.
Arius was designed so you can install it yourself. Every kit includes the tools you need, along with easy-to-follow written instructions and video guides that walk you through the entire process.
Most customers are surprised by how simple the installation is, and how satisfying it feels to do it yourself.
Does Arius significantly reduce water pressure?
Not significantly.
Because Arius contains both a filtration system and a water softener, there is a small reduction in water flow as water passes through the filtration media. This is completely normal and a sign that the system is doing its job. For the vast majority of users, the trade-off is well worth it.
What does Arius remove from water?
It filters chlorine, chloramine, heavy metals (like lead, cadmium, chromium, arsenic), VOCs, disinfection byproducts (DBPs), and softens hard water by removing calcium and magnesium minerals.
How often do I need to replace the filters?
Filter replacement is recommended every 3 months. The softener does not need replacing, it just needs a simple salt recharge about once every two weeks for a household of two. The recharge is done with a twist of a valve.
