RJK30 HITACHI Automatic Water Purification Filter

Review HITACHI Automatic Ice Water Purification Filter Japan

The Hitachi RJK-30 Automatic Water Purification Filter is a state-of-the-art water filtration system designed to provide clean and safe drinking water for homes and offices. This filter utilizes advanced technology to remove impurities and contaminants from water, ensuring that every drop is of the highest quality.

The RJK-30 is an automatic reverse osmosis (RO) filter, which means it uses a semi-permeable membrane to filter out particles as small as 0.0001 microns.

Additionally, the RJK-30 comes with a multi-stage filtration system that includes a pre-filter, activated carbon block filter, and the RO membrane. The pre-filter removes larger particles, while the activated carbon block filter eliminates chlorine, volatile organic compounds (VOCs), and other tastes and odors.

This filter also features an automatic self-cleaning function, which helps to maintain the filter's efficiency and prolong its lifespan. The system automatically backwashes the RO membrane with a solution of salt and water, which helps to prevent scale buildup and maintain the membrane's integrity.

The RJK-30 is easy to install and maintain, with a sleek and compact design that fits neatly under the sink. It comes with all the necessary components for installation, including a faucet, hoses, and adaptors. The filter also includes a tank for storing purified water, which ensures a steady supply of clean water for drinking and cooking.

Moreover, the filter has a high-capacity tank that can store up to 3.2 gallons of purified water, which is perfect for households with larger water usage. The tank is also made of food-grade materials, ensuring that the water remains safe and free of contaminants.

The Hitachi RJK-30 Automatic Water Purification Filter is an excellent investment for anyone looking for a reliable and efficient water filtration system. With its advanced filtration technology, easy installation, and automatic self-cleaning function, it provides peace of mind and clean, safe drinking water for years to come.
