CARBON BLOCK FILTERS

Chlorine, Taste & Odour

Whether you are looking for a filter to improve the taste and clarity of drinking water, or a pre-filter for a wider water treatment system our carbon filters are an excellent choice. Carbon is widely used for its ability to remove chlorine, but can also effectively treat a much wider list of contaminants including lead, pesticides and hormones to name just a few. Each size of carbon filter we offer comes with moulded end caps and an integrated gasket to ensure a positive seal with your filter housing, complete with an outer wrap to protect against sediment built up.

How Long Do These Carbon Block Filters Last?
We recommend changing these filters every 12 months for properties with 1-2 occupants and every 6 months for properties with 3 or more occupants. For commercial applications, the filter lifespan will depend on your daily flow rate.

Why Choose Our Carbon Block Filters?

Treats several contaminants in one filter cartridge
Effective treatment of hormones, organics and PCB’s
Integrated gasket and end caps for a positive seal
Available to suit flow rates up to 906 litres per hour

 Trustindex verifies that the original source of the review is Google. Very pleased with the service. 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!

 Trustindex verifies that the original source of the review is Google. Easy to order, quick delivery, good communication. Resclean worked a treat; one treatment cycle and soft water is back again from our 12 yr old softener!
