Water quality is a common issue that is a concern around the world. To provide healthy drinking water, RIFENG has now launched two pre-filters, R1 and R2.
Pre-filter for primary filtration of home users' water supply systems. Usually installed after the water meter of the inlet pipe, before the first water equipment. Use the precision filter to directly intercept impurities in the water, and effectively filter rust, debris, sediment, red worms, and algae in the source water to protect health and other equipment in the water supply system.
• Purifies water in micron filtration
The micron filter cartridge can stop particles over 40 microns, protect faucets and valves, and ensure household water quality.
• Easy maintenance for a long service life
The filter cartridge can be detached to be cleaned or replaced.
• Visible purifying process
Through the transparent bottle body, it is convenient to check the water quality and impurities.
• Wide range
According to different installation demands, the copper body has two types of structure, general fixed and 360 rotation, and various joints and colors are available to match.
• Pressure balance technology and pressure monitoring can effectively protect water equipment.
• Double scrub and two filter cartridges to make cleaning better.
• More convenient to use backwash design and automatic wash without dismantlement.
• A memory scale for regular cleaning and a filter flush reminder make cleaning easier.
