India’s first water

Yes, for municipal, borewell and tanker supply, as long as the incoming water is under 1,500 TDS. IAPMO India tested it on feed water from 250 to 1,500 mg/L at three hardness levels each, and the ten purification stages deal with microbes, chlorine and particles before the CDI cell does its work.

An RO membrane separates by size, so it removes contaminants and much of the natural minerals together, and sends roughly three litres to the drain for every litre you drink. Biofier’s patented CDI uses electrically charged surfaces to selectively pull out the unwanted dissolved ions, retaining more essential minerals and recovering up to 70% of the water.*

That is what the independent tests were for. TÜV SÜD analysed both waters from the same supply: Biofier water carried more calcium, magnesium and bicarbonate than the RO beside it, with every reading inside the Indian drinking-water standard. In the 15-day germination study, the seeds grown on Biofier water sprouted more, grew 42.1% longer by day seven and finished with more minerals in the plant.*

A remineralisation cartridge sits after the membrane: the RO first strips almost everything out, then a consumable doses a few selected minerals back in, at a rate that depends on the cartridge and its age. Biofier never removes them in the first place, so the water keeps more of its own natural mineral profile. One rebuilds water. The other preserves it.

The CDI chamber captures charged dissolved impurities, such as excess salts, sodium, chlorides, nitrate and dissolved heavy-metal ions, on its electrodes and flushes them away when it regenerates. Before that, a microbe-deactivating filter neutralises bacteria and viruses, activated carbon removes chlorine, odours and organic compounds, and sediment stages catch particles. Ten stages, each with one job.

A conventional RO can discharge around three litres for every litre it purifies. Biofier’s water efficiency is validated by IAPMO with a 5-star water-saving rating, and it recovers up to 70% of the water it takes in. For a typical household that adds up to thousands of litres a year that never go down the drain.*

Nothing for the first five years. Maintenance and consumables are included, so filter changes and service visits are taken care of. The CDI cell also cleans itself by reversing its polarity, and the Rhion app shows filter health and tells you when a service is due.

Scheduled service visits and consumable replacements for five years from installation, at no additional cost, so the purchase price is the only cost in that window. The standard product warranty applies alongside it.

Indian supply changes with the season and the source, which is why Biofier was tested across fifteen feed conditions rather than one. The CDI control adjusts to the incoming water, the live TDS display shows you what is coming out, and as long as the feed stays under 1,500 TDS the output stays consistent.

The water is identical from both. Terra Blu+ adds hot water on demand, with hot, warm and ambient dispensing, touch-to-dispense and 5 + 1 litres of storage. Terra Blu keeps it simple with push-to-dispense and 5 litres of storage. If you make tea, coffee or baby feeds often, choose Terra Blu+.

It logs every sip and understands what you drink, shows your daily hydration progress and mineral contribution, sets shared family goals, tracks your streaks and the water Biofier has saved, and monitors filter health and maintenance needs so service is proactive rather than reactive.

₹999 reserves your Biofier in the first production run and is fully adjustable against the purchase, at the pre-book price of ₹39,999 for Terra Blu+ or ₹36,999 for Terra Blu. It is fully refundable right up until your unit is dispatched.
