Our Inline Limescale Filters are an excellent solution for water-using appliances like washing machines and dishwashers – protecting them against limescale build up. The filter comes pre-filled with polyphosphate crystals which slowly dissolve into your water, preventing calcium and magnesium molecules from forming a hard scale. Once the crystals have dissolved, the system can easily be refilled thanks to a screw-top design. Complete with 3/4″ BSP threaded connections for an easy installation onto the feed of your appliance (such as a washing machine or dishwasher).

INLINE LIMESCALE FILTERS

Limescale & Corrosion Protection

Excess limescale build-up can cause costly damage to appliances over time, even leading to premature breakdown if left unmanaged. Our Inline Limescale Filters are designed to be installed on the feed to your water-using appliances, protecting them against limescale and corrosion using a technology called polyphosphate. The filter is quick and easy to install and starts working immediately, with no loss of flow or pressure. Featuring 3/4″ BSP inlet and outlet connections (male threaded outlet, female threaded inlet) supplied with washers for a leak-free seal.

How Long Do These Filters Last Between Refills?
Each refill lasts for up to 30,000 litres before replacement crystals are required (depending on your water hardness and water quality). The polyphosphate crystals dissolve slowly over time, so should be visually checked every 1-2 months. Each refill uses approximately 160g of polyphosphate crystals.

Water treated with polyphosphate can be heated up to a max temperature of 75-80°C beyond that temperature the media gradually loses its efficacy

There was an issue with the water softener I ordered initially, but then following communications made the replacement process quite pleasant. Happily recommend this company. Thanks to Becky for working with me. Great follow up support 😊😊😊

 Trustindex verifies that the original source of the review is Google. First time using this company and product and i wasnt dissappointed. Communication was easy and quick resulted in an easy order and now having fitted the filter i can say its a great product easy to install and appears good quality apart from the four mild steel bracket screws stainless would have been better considering the environment these are fitted. All in all, very pleased and would highly recommend .

 Trustindex verifies that the original source of the review is Google. Excellent local company and genuinely lovely people to deal with. Really helpful and knowledgeable, with great advice about my water softener and the correct salt to use. They even gave me some resin cleaner at no charge, which was a very kind gesture. Fantastic friendly service and I’ll definitely be returning for my salt in future. Highly recommended.

 Trustindex verifies that the original source of the review is Google. Excellent service.  Product proved my softener was not working as it should.  I fully serviced it and cleaned with Resin Clean returned to service and it is now working as designed.  Very pleased.

 Trustindex verifies that the original source of the review is Google. If you're thinking about a water softener then i HIGHLY recommend Ultra Soft Water Softeners Ltd.

Great softeners and exceptional customer service. The water softener I bought needed some adjustments with the installation setup where I supported throughout. The customer service is honestly next level. I had countless calls with Becky Gillett, the Sales Manager, over a period of months to get to the bottom of it. She was incredibly patient with me, staying on the phone and doing video calls to walk me through the programming instructions step-by-step while I changed the settings and ensured all was installed correctly.

All the staff here have been great, but Becky really stuck with me from start to finish to make sure it was sorted and working well. It runs like a dream now.

HIGHLY recommend them!
