Tankless RO System – Reducing the Risk of Bacterial Growth, Providing Better Water Quality

The tankless RO system utilizes advanced reverse osmosis technology to treat tap water into pure water that can be directly consumed. Compared to traditional water purifiers with tanks, this system features fast water production, no need for a storage tank, reducing the risk of bacterial growth and secondary water pollution, providing fresher and purer water. This system has a compact structure, taking up less space in places such as the kitchen and under the sink, saving space.

Description

The two-stage filter cartridge tankless RO system uses a two-stage filtration technology. The first-stage filter cartridge is a PCT composite filter cartridge, which is used to remove large particles, sediment, rust, odors, residual chlorine, and other pollutants from water, protecting the RO membrane from damage by large particle impurities. The second-stage filter cartridge is an RO membrane filter cartridge. It can remove dissolved pollutants as small as 0.0001 microns from water, including heavy metals, bacteria, viruses, and chemical substances, ensuring the purity of the water reaches a level suitable for direct drinking. It is suitable for small households, offices, and other places.

Features
  • Space-saving. The tankless design eliminates the need for a storage tank, making it compact and ideal for small kitchens and homes with limited space.
  • Fresh water quality. Instant filtration allows water to flow directly to the outlet after filtering, reducing the risk of secondary pollution and ensuring fresh water quality.
  • Reduced bacterial growth. Without a water storage tank, the risk of bacterial growth from prolonged water storage is avoided, ensuring safe drinking water.
  • Reduced replacement frequency. Simplified filter cartridge configuration for easy maintenance, equipped with a self-cleaning function for the filter cartridge, resulting in a lower replacement frequency and reduced usage costs.,
  • High water flow rate, fast water output. The tankless design, with its advanced instant filtration and drinking technology, provides a fast water output speed to meet users' immediate drinking needs.
  • Pure &filtered dual water outlet. The faucet offers dual modes for pure water and filtered water, allowing users to switch between direct drinking water and domestic water as needed.
  • Efficient impurity removal. The filer rating of the RO membrane can remove most dissolved harmful substances, such as heavy metals and pesticide residues, effectively improving water quality.

Description

The four-stage filter cartridge tankless RO system uses four-stage filtration technology. The first-stage filter cartridge is a thickened PP cotton filter cartridge, used to remove large particles, sediment, rust, and other contaminants from water. The second-stage filter cartridge is a CTO filter cartridge, using imported carbon source sintering technology, efficiently removing chlorine and heavy metals. The third-stage filter cartridge is an RO membrane filter cartridge. The RO membrane can remove dissolved pollutants as small as 0.0001 microns from water, including heavy metals, bacteria, viruses, and chemical substances, ensuring the purity of water reaches a level suitable for direct drinking. The four-stage filter cartridge is a T33 activated carbon filter cartridge, with coconut shell acid-washed activated carbon to improve the taste of water. It is suitable for small to medium-sized households, offices, and other places.
