Why do we need to switch from RO water purifiers?

Reverse osmosis water purifiers use a semi-permeable membrane to remove ions and unwanted particles from the water to make it drinkable. RO water purifiers are now an incorrigible part of the household. They provide us with pure water in the comfort of our house. Now we don’t have to struggle for pure water. But, are these water purifiers really that great? Are ROs solving our problem for pure water or are they contributing their fair share in the world’s water crisis?

Everybody knows we are going to face a water crisis in the near future if we don’t adopt effective measures to cut down our water wastage. Five times as much land as today is likely to be under “extreme drought” by 2050. In 2050 the growing population will result in a 19% increase in agricultural water consumption. Agriculture has cut down its water requirement drastically by adopting drip irrigation. But, can we say the same for households (I would say “Certainly not”)?

Here are some reasons why you might want to shift from conventional ROs to more efficient alternatives.

1. They purify less and waste more

Did you know that for every gallon of water that RO (Reverse Osmosis) purifiers purify, it wastes about four gallons of water? So, this leaves most of the ROs with just 25% efficiency (Doesn’t sound too great). This means if we make 10 gallons of water a week, we will be wasting about 40 gallons of water.

2. Removes minerals too

RO removes impurities from water and along with them, it removes essential minerals such as magnesium, iron, calcium, and sodium, which when removed from water may cause mineral deficiencies. The deficiency of essential minerals can disturb the osmotic pressure and create an electrolyte imbalance. The removal of minerals also decreases the pH of water.

3. RO Purified water absorbs minerals from the body

 The World Health Organization has confirmed that reverse osmosis water doesn’t contain any minerals, and when consumed absorbed minerals from the body. This means the minerals that we consume through food are being removed from the body by urination.

The solution to the problem

Nowadays, the market has modern and better alternatives for purifying water without depriving it of any essential minerals.

Gravity based water purifiers are available in the market. They don’t just purify the water without any wastage but are also much cheaper than RO purifiers. Unlike RO purifiers, these purifiers don’t require electricity for purifying water and hence are sometimes referred to as off-line or non-electric water purifiers. These Gravity based water purifiers typically use activated carbon, which is made up of small carbon granules to absorb impurities from water. The activated carbon also reduces bad odor, pesticides, and colors from the water. Gravitational water purifiers also require less maintenance than the RO purifiers. These can be the solution to our water problems. So, the next time your RO needs maintenance, you might want to consider buying one of these.
