About
The Coldstream FTO Plus ceramic water filter replacement cartridges protect against chlorine, chloramine, heavy metals, chemicals, pesticides, herbicides, bacteria, parasite cysts, microplastics, and fluoride.
The Coldstream FTO Plus ceramic gravity filters are also water purifiers, made by KLT Filtration, located in Norfolk, UK. Established in 2013, they have developed a unique ceramic injection moulding technology and a state-of-the-art manufacturing facility to produce high performance ceramic water filters to effectively remove 99% of known contaminants from drinking water. Determined to achieve zero waste, their facility is powered by energy generated from wind and solar panels.
KLT Filtration’s ceramic filters are sold under their Coldstream brand to provide water containing only beneficial minerals and electrolytes, which naturally give water its fine taste.
The outer shell of the Coldstream FTO Plus gravity filter is a unique and specially formulated ceramic which gives maximum protection against bacteria and removes all particles and micro-plastics.
The interior of the filter contains black granular activated carbon for the adsorption of chemicals and heavy metals.

Performance test data
Click here for Performance test data
Accredited test results show that each Coldstream FTO Plus ceramic water filter maintains very high contaminant reduction rates to 3000L (792 US gallons) of use. (See exceptions.)
Once wetted, it is recommended that the filters be replaced after a maximum of 12 months.
Actual service life of your gravity filter will depend on the unique chemistry of your water source.
Exceptions
Water treated with fluoride or containing significant levels of nitrate, nitrite, sulphate, and selenium are exceptions to this performance. Sustained protection from these challenging contaminants will require more frequent replacement of the filters.
Watermatters recommends water treatment with a reverse osmosis system or with a water distiller for customers with elevated levels of these compounds in their tap water.These challenging compounds are not present in the tap water that most of our customers run through their water filter. Check your local water quality report to learn more.

Installing the Coldstream FTO Plus ceramic water filters
- Fit the rubber washer over the threaded stem of the filter.
- Insert the threaded filter stem through a hole in the bottom interior of the upper chamber.
- Secure the filter in place with the wing nut provided.
- Repeat with second filter.
- Flush multiple passes of water through the upper chamber until the finished water tastes clear. The filter is now ready for use.
Note
a. It is normal to see black carbon fines in the first flush of water. Once flushed, the filter will produce clear water.
b. The newly installed filter will not achieve maximum flow rate until it has become fully saturated. Up to 45 minutes may be required to achieve saturation, depending upon the characteristics of the water being flushed.
Cleaning the Coldstream ceramic FTO Plus gravity filter
After a period of use, if the flow rate has dropped off significantly, simply remove the filter from the housing and carefully clean the outer ceramic surface by brushing lightly with a scouring pad (no soap!) under cool running water.Do not let any water enter the stem of your filter during the cleaning process.
Re-install the filter.
Wash your hands before and after cleaning your filter.
We recommend that you clean your entire gravity water filter system once per month.
What to do with your Coldstream FTO Plus ceramic gravity filters during vacation or periods of disuse.
- Empty your system and remove the filters.
- Place the filters in a cool, dry, clean and well-ventilated area.
- Upon return, re-install the filters and flush them with 4 litres (1US gallon) of water before resuming use for drinking.
Note
Alternatively, during periods of hot weather, the filters can be sealed in an airtight plastic container or Ziplock bag and stored in the refrigerator. (Not the freezer!)How to store new, unused Coldstream FTO Plus ceramic gravity filters.
When storing new, unused Coldstream FTO Plus water filters for future use, be sure to store them in a clean, cool, dry environment.
