AquaHouse NSWS Scale Prevention system. The NSWS system prevents limescale using a filtration process with proven 99.6% effectiveness and will also descale existing pipework and appliances. Long filter life of up to 3 Years.
Cost effective chemical and salt free alternative to conventional water softener.
WFM-NSWS-S
Scale prevention system for use in small/average homes. Proven scale prevention technology at 99.6% effectiveness makes this a genuine alternative to conventional water softeners. If you would also like to filter your water at the same time as preventing scale (to remove chlorine, chemicals, etc) then please search for our EcoPlus whole house filter which features both scale prevention and water filtration in one unit.
The scale prevention effect takes place within the filter without adding any salt or chemicals into the water. The filter does this by using a process called Template Assisted Crystallization (TAC), which conditions the water and converts the hardness minerals in the water (Calcium and Magnesium) into harmless, inactive microscopic crystals. This prevents the Calcium and Magnesium from bonding together to form lime-scale, and also over time will de-scale existing pipework and appliances. Because of this process no natural minerals are lost from the water, and no chemicals or salts are added either.
Water which has undergone this filtration process has an effect which prevents scale from forming in pipework and appliances, around sinks and washbasins, and will help prolong the life and efficiency of your appliances. The scale prevention media has been tested independently against the international protocol for scale prevention and has achieved up to 99.6% effectiveness rating.
You will need to replace this filter in the system just once every 2-3 years (depending upon incoming water quality)
Template Assisted Crystallization compared to a water softener
![]() | ![]() |
| In an untreated hard water supply, the hardness minerals such as calcium form calcium carbonate - rock hard deposits we know as lime-scale. | The polymeric template beads attract the mineral ions on a molecular level in a process known as Template Assisted Crystallisation (TAC). |
![]() | ![]() |
| The minerals collect within the nucleation points on each polymeric bead and form microcrystals. | After forming, the microcrystals break off from the template beads and continue through the water supply, as inert particles unable to form hard scale |
![]() | ![]() |
| Hardness minerals in water treated by the TAC process pass through pipework and appliances, without sticking to form hard lime-scale, beneficial to plumbing fittings and heating systems. | Where water evaporates, the water marks left behind consist of the mineral residue in crystalline form, and wipe away easily with general cleaning, not requiring aggressive descaling. |
The system comes complete with new filter installed, pod, spanner, and mounting bracket. The system has 3/4" BSP threaded nipples pre-installed, and is simply connected in-line with your cold water mains pipe to filter the water for the whole home / premises. This is a very straight forward installation for any plumber.
We also have a full bore compression fittings bypass kit and flexible hoses available as an optional extra, these are useful for tight installations where the system cannot be installed in-line with the pipe and needs to go underneath / above the pipe instead. Please see "accessories" tab for fitting kits in 15mm and 22mm sizes,

At last, a limescale deterant that works!
I've had mine installed for about 2 weeks and the limescale build-up around the taps has already gone soft and can be wiped off.NSWS Proven 99.6% effective Scale Prevention, Water Softener Alternative
we had this installed nearly 3 weeks ago and it has made a noticeable difference to our limescale problems. There is now no build up around taps, sink etc and the kettle is completely clear - which for the water in this part of East Anglia is an excellent outcome. There is still some sheen appearing (silica?) which easily wipes off - nothing like limescale. Excellent product so far - easy to fit with no salt added to the environment. very happy with it.Not Convinced
I had one of these fitted to the incoming supply 3 years ago so now is the time to have it replaced. not sure if I'm going to spend £100 on a cartridge because I haven't noticed any difference in the scale build up around taps, inside the kettle etc. I gave a two star rating based on ease of fitting and I suspect it must filter something.
