Pearl OneFlow Hard Water Filter

You've arrived at the right place if you so frustrated with the limescale in your drinking water that you'll do anything to have a cup of scum free tea!

Our Pearl OneFlow is a high performance anti-scale drinking water filter system that prevents scale by transforming dissolved hardness minerals into harmless, inactive microscopic crystal particles. These particles make their way through plumbing systems without latching onto pipes, fixtures, valves or heating elements.

*Please note that this filter system does NOT remove chlorine or chemicals. You'll need our Oyster Taste and OneFlow hard water filter for that.*

You can install this filter either under your sink or on the bench top.

The housing dimensions are 34H x 14W x 13D (volume occupied in cm).

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.

Your kit will include:

• 1 x white filter housing
• 1 x single white housing bracket
• 1 x canister containing 250ml of Watts A8210 OneFlow anti-scale media

Important information about TAC media

Add water to the canister containing the TAC media and leave it to stand for two hours before dropping it into the housing. If you don't do this some of the smaller particles can escape into the pipework and be lost.
