Type of use

Reverse osmosis units are used for three reasons: Firstly, to soften the water a little, even if it is rather advisable to opt for a water softener if yours is very hard.

Then, aquarists use aquarium reverse osmosis units to provide their fish with very soft water, without which these animals would not survive. Finally, the most common reason is that the water purifier is used for domestic purposes to make tap water suitable for human consumption.

Freed from these particles, everyone, including those preparing baby bottles, can ingest the water. Another strong point is that it makes it possible to limit or even stop buying plastic bottles.

When the water is treated, it goes through three successive phases during filtering, which means that we can estimate, for some devices, that for a liter of pure water, 5 liters are discharged in terms of dirty water.

While the reverse osmosis unit reduces the use of plastic, this can nevertheless impact water consumption. To avoid waste, some brands advocate recycling this water for plants, among others.
