Our Refillable DI Resin Filter Kit allows you to produce small volumes of deionised water on demand. Commonly used in aquatics and lab settings, or as a ‘final polish’ stage after a reverse osmosis system to bring the TDS down to 0ppm. The DI resin filter supplied with this kit comes pre-filled with virgin MB-115 mixed bed de-ionising resin, which once expended can be opened, emptied and refilled multiple times to reduce plastic waste and reduce operating costs.

Estimating Resin Capacity

The pure water production capacity of DI resin depends on several factors, with the most important being your feed water TDS. The higher your feed water TDS reading the lower the lifespan of your resin. To get an approximate capacity figure please refer to our DI Resin Calculator for more information.

REFILLABLE DI RESIN FILTER KIT

Produce Pure Water On Demand

Deionising resin is a popular water treatment technology, as it removes all dissolved minerals leaving you with pure water at 0ppm (parts per million). Our Refillable DI Resin Filter Kit makes producing small batches of deionised water easy. The kit comes with everything you need to get started including a 10” clear filter housing (with 3/4” inlet and outlet), wall bracket, spanner and a refillable DI resin cartridge. Replacement DI resin is available to purchase separately in 1L and 25L volumes, with the filter containing 1L~ per refill.

What Is The Lifespan Of The DI Resin Filter Cartridge?
The resin inside the filter has a finite life – so needs to be replaced when it is expended. We recommend using a TDS meter to test the quality of water produced and replace the resin when the TDS increases. On mains water (300ppm) you can expect approximately 65L of pure water before the resin is expended, where as with RO water (10ppm) you can expect up to 12,000L.

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!
