Fluoride removal Purifier Add-Ons:

The add-on white container is made of Food Grade High Denisty Polyethylene

• Size: 12” diameter x 14” height.
• It has 12 perforated Plastic cylinders with lids on either side, packed with lime stone pebbles doped and coated with our proprietary Fluorosorb (nano-material to break and remove fluoride ions) developed in association with PSG College of Science & Technology, Coimbatore.
• In regions with high fluoride content in water is present in water, these add-on white container with 12 perforated cartridges containing fluorosorb TM,R a proprietary material developed by Watsan acts as a fluoride remover, bringing it down to 0.7 mg/ltr much lower than the permissible standard of 1.5 mg/litre.
• Method of usage: This fluoride remover container along with the 12 perforated cartridges has to be used along with Terafil Standalone filter.

After soaking overnight (or minimum of 8 to 12 hours) the fluoride in the water is broken and seperated. The fluoride free water then, should be poured into our standalone water purifier in which other contaminants like pathogens, heavy metals and turbiditiy are removed and the water brought down to potable level.
• This does not have heavy pungent alumina smell like other fluoride removers.
• Added advantage of nano-dosage of calcium entering along with potable water in your body, to gain back the depleted strength of the affected persons’ bone and teeth.
