Product Description

Anti Scale / Scum Removal Unit - for Very Hard Scale Areas

This filter contains 100% anti-limescale solution - the same top anti-scaling and anti-heavy metals powder used by major brands like Brita. It is designed for very hard scale areas and should last you *up to 6 months - possibly more - depending on your local area. 

Please note this filter only removes limescale. It doesn't improve the taste and odour of your water. Solution: if you want your water to taste better aswell, simply twin your current housing unit with this housing unit.

You can read more and buy that here. Or call us for further details on 0800 009 6611.

This is a simple plumbed in system so it goes under your sink. No cutting of pipework is required.

It assumes you already have a water filter connection and tap. If you don't simply choose your tap here. And your self-tapping water filter connection to your water supply here. (Simply add these to your basket before you checkout).


Quick and easy installation: You could be drinking fully de-scaled water within 15 minutes of receiving your kit.

It takes us 2 minutes to set up one of these systems. Of course we've done it many times, but we're saying this to give you an idea of how easy it is. You can expect it to take you between 10 to 15 minutes or so, to set it up yourself.

Fit it once and use it forever! (These systems are very tough and should last you at least 20 years).

Plus: Special Bonus: Order today and we'll include a Free easy-change spanner (Usual price £7.39).

You get a free and friendly after sales helpline.

Features Summary:

  • 3 litres per minute flow rate - That's fast enough. No waiting around
  • Compact design requires little space under sink
  • Simple installation: No plumbing required
  • Easy cartridge changes
  • Economical - a replacement cartridge costs £29.97 and lasts *up to 6 months. Save ££s on bottled water - plus it's healthier. 
  • Guaranteed for 3 years - Buy with confidence. If there are any problems we'll replace it for you.


Special Note: Your Options

This anti-scale filter only contains anti-scale powder/media. So while it's very good at combating scale it doesn't filter out chlorine and other impurities or improve the taste of your water.

However if you want that capability aswell there is a simple solution. You can "twin" the total scale filter with a great taste and odour filter. 

Twinning filters simply involves two housing units sitting side by side under your sink.

ie Unit 1: this excellent taste and odour water filter twinned with Unit 2: this anti-scale housing unit (which contains this Anti Scale Ten Inch Cartridge). 

If you want this solution we can offer you a £20 discount on the extra housing unit. 

To get this call us on 020 8761 6611 and we can do it all for you.

If you prefer order direct then call us or email us afterwards and we will refund your payment with the £20 discount.


*Changing Your Cartridge

Your filter cartridge *should last *up to 6 months in 95% of UK Water Areas

Depending on local water chemistry.

Please note that it's hard for us to be totally certain this filter will stop scale in your drinking water for a full 6 months. This is because there are thousands of local water treatment plants in the UK. Each has a unique water chemistry - which can change regularly. (And it’s hard to tell by exact area because even within the same postcode the water source can vary). 

However, having said that, please rest assured that the cartridges do usually work well for the full 6 months for 95% plus of our customers.

However, even if you're in a particularly bad area the filter should last for 3 months plus. What can make a big difference is the flow rate of water going through the filter. The slower the better. You might need to reduce to 2 litres a minute. (This will fill your kettle for a cup of tea in a few seconds). 

To adjust the flow rate simply use a flow restrictor / shut off valve. If you don't already have one ask us and we'll send one for free with your new filter. (Usual price £6.97). Ask us!

We guarantee this filter will remove scale for at least three months. If it doesn't send it back and we will refund you on a pro-rata basis - click here for more details

No scale - Amazing result!!!. We have some of the hardest water in the country, spent a fortune on brita and other inline filters, but within a couple of weeks the scale would be back. Not with this filter, the results are amazing, the kettle is completely free of scale weeks after install...could not be happier with the result!!!!". Independent Review by monkeyball

What Type of Plastic is this Housing Made From?

These housing units are made of PolyPropylene (PP).

If you're concerned about plastics - we think you're right to be.

Plastics like BPA's (often found in food and water containers) and Phthalates (in PVC products etc) are linked to cancers, fertility problems, obesity, hormone / endocrine disruption and God knows what else. 

The problem is they leach into the food or liquid they're holding.

However PolyPropolene (ie our housings) does not contain BPA's or Phthalates. and is thought to be much safer because it doesn't leach chemicals like some other plastics do.

PolyPropolene is one of the oldest and most commonly plastics with no known negative health effects after seventy years in widespread use (Sources: ESIS – European Chemical Substances Information - and the Hazardous Substance Data Bank (USA).
