Why Choose Reverse Osmosis?

Reverse osmosis, also known as RO, is one of the most effective water filtration methods available, helping to reduce a wide range of unwanted contaminants while improving the taste, clarity and quality of your drinking water.

The result?

Cleaner, fresher-tasting drinking water

Confidence in every glass

Less reliance on bottled water

Better tasting tea, coffee and food

High-quality filtered water whenever you need it

How Reverse Osmosis works

Reverse Osmosis works by forcing water through a semi-permeable membrane, whereby some molecules pass through but not others. This process removes contaminants, impurities, and minerals from the water.

Profine ZERO Reverse Osmosis

ZERO is a patented non-electric RO system made in a compact form, including pre-treatment and post-treatment with bacteriostatic action capable of producing osmotic water with instantaneous high flow
rate.
