Oyster Taste and OneFlow Hard Water Filter

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

Our Oyster Taste and OneFlow hard water filter 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.

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 filter also removes chlorine and chemicals; improving the overall taste and smell of your water. 

*If you only want to filter out limescale from your drinking water then all you'll need is our Pearl OneFlow hard water filter. 

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

The housing dimensions are 34H x 26W x 13D (volume occupied in cm).

• 1 x Watts F109009 coconut shell carbon block filter cartridge for chlorine, taste and odour reduction*
• 1 x canister containing 250ml of Watts A8210 OneFlow anti-scale media 
• A choice of 5 taps or you can choose the 'no tap' option.

• DIY instructions - No need for a plumber!

Cartridge details:

• Watts F109009 coconut shell carbon block filter cartridge for chlorine, taste and odour reduction in water.*
• 2.5 x 10".
• 5 micron - up to 99% chlorine removal.
• Chlorine reduction >4,000 gallons @ 1.0gpm or 12 months; whichever comes first.
• Thick wall carbon construction for superior performance.
• Outperforms granulated activated carbon (GAC) cartridges as it has superior chlorine reduction, lower pressure drop and will not channel.
• Media wrap between centre tube and carbon block to reduce carbon fibres.
• Maximum operating pressure - 125psi.
• Operating temperature - 50°F to 125°F / 10°C to 52°C.
• Tested and certified NSF/ANSI standard 42 for materials only.
• FDA grade components and materials.
• Tested and verified by independent laboratory testing.

* On some occasions a CTO 2510-05 cartridge may be used in the kit. This does the same job as the Watts F109009. They're just different brands.

And:

• Canister containing 250ml of Watts A8210 OneFlow anti-scale media / 2.5 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.  

What order do the cartridges go in?

In most circumstances the lowest micron rated cartridge goes last in the sequence (on the water out / blue tubing side). For the Oyster Taste and OneFlow hard water filter the 5 micron carbon block cartridge goes first in the sequence, followed by the canister containing 250ml of Watts A8210 OneFlow anti-scale media.
