Reverse osmosis (RO) water purifier is a type of water filtration system that removes impurities and contaminants from water by pushing it through a semi-permeable membrane.
This membrane allows water molecules to pass through, while blocking larger contaminants like bacteria, viruses, and minerals.
RO is one of the most popular and effective methods for water purification as it removes 99% of impurities including dissolved salts and harmful chemicals such as lead, chlorine, and arsenic, resulting in clean, safe drinking water.
Some of the advantages of an RO water purifier are that they are low maintenance, easy to use, and have long-lasting filters that only need to be replaced every 6 to 12 months, depending on usage.
Additionally, RO units are usually compact and can easily fit on a kitchen counter or under a sink, making them a great option for household use.
