Moby Taste and OneFlow Hard Water Filter

Improve the taste and smell of your mains water and remove chlorine and sediments.

Also solve your scale problems with our OneFlow cartridge.

Our Moby Taste and OneFlow hard water filter fits to your cold water tap so there's no need for a separate water filter tap.

If your water is harder than 25 grains (427 ppm CaCO3) then OneFlow may not be suitable for you. Check with your local water supplier who will be able to tell you what the hardness measurement is. 

Please note that a TDS meter may give you a higher reading but it's measuring all total dissolved solids and not just CaCO3. This is another reason to contact your local water supplier.

This is an undersink water filter and when fitting allow for a minimum of H 38cm x W 60cm x D 18cm.

This is not a water softener. The Moby Taste and OneFlow Hard Water Filter is much more environmentally friendly than one of those. Take a look at our recent blog post about OneFlow by CLICKING HERE.

or on some occasions a different cartridge may be used in the kit. This does the same job as the Watts WCBFF975. They're just different brands.

And...

• Watts canister containing 500ml of A8210 OneFlow anti-scale media / 4.5 x 10"
• Chemical free scale prevention and protection - converts hardness minerals to harmless, inactive microscopic crystals.
• Virtually maintenance free - just replace your OneFlow cartridge every 1-2 years.
• No control valve, no electricity and no wastewater.
• OneFlow is not a water softener. It does not add chemicals into your water or remove the beneficial minerals. 

Do you have to install a mains water filter under the sink?

No, you don't. You can install your mains water filter wherever the cold water supply enters your house. This could be a utility room, garage, or other location. 

What order do the cartridges go in?

In most circumstances the lowest micron rated cartridge goes last in the sequence (on the water out side). For the Moby Taste and OneFlow Hard water filter the 5 micron carbon block cartridge goes first in the sequence, followed by the canister containing 500ml of Watts A8210 OneFlow anti-scale media.
