What is a Reverse Osmosis Membrane (RO System)?

Water produced by reverse osmosis membranes is pure water containing almost nothing but water molecules.

Except for natural water, most water sold at convenience stores and delivered to your home in Japan, Thailand, and other countries around the world is produced by reverse osmosis membranes.

This is the most advanced technology in today’s water purification, including the production of commercial drinking water, the conversion of seawater into drinking water, and the conversion of sewage into drinking water during disasters. The reverse osmosis membrane water purifier is a water purifier that can easily produce pure water in your own home.

Polka Dots currently has rental contracts with over 2,782 households (as of April 2025) in the Sukhumvit area alone.

In an ordinary apartment, the main body of the water purifier is installed under the kitchen sink, and a special faucet for the water purifier is installed above the sink.
