In the pursuit of a healthy lifestyle, the quality of household drinking water has become a major concern for many consumers. Recently, an under - sink RO water filter has become a hot topic in the home furnishing market with its outstanding performance and innovative design, offering people a better choice for high - quality drinking water.

This water filter adopts an advanced 4 - stage deep purification system, consisting of PP cotton, activated carbon, reverse osmosis membrane (RO), and granular activated carbon filter elements. The PP cotton serves as the first line of defense, effectively intercepting impurities with a diameter larger than 5 microns, such as rust and sediment. The activated carbon further adsorbs pesticide residues, residual chlorine, and organic solvents in the water. The high - precision reverse osmosis membrane, the core component, has a filtration accuracy of up to 0.0001 microns. Almost only water molecules can pass through it, physically separating harmful substances like bacteria, viruses, and heavy metals. The final granular activated carbon filter element can remove organic matter and residual chlorine in the water, improving the taste of the water quality, ensuring that the effluent is clear and sweet, and meeting the national direct - drinking water standards.

The reverse osmosis technology it uses is the key to ensuring water quality safety. Through this technology, the water filter can efficiently remove various harmful pollutants such as heavy metals in the water, providing reliable protection for healthy drinking water in families. At the same time, the water filter is equipped with an automatic flushing function with 4 filter element flushing modes. It can automatically flush the filter elements in different situations, such as when starting up, during water production, after a certain period of cumulative water production, and when the water level drops. This effectively maintains the freshness of the water quality and extends the service life of the filter elements.

Considering the convenience of users, this water filter is designed with a self - service core replacement function. Users can easily replace the filter elements at home with just 3 simple steps, without having to wait for professionals to come, which greatly saves time and cost. In addition, the water filter pays attention to noise reduction in its design. The working noise is controlled below 45 decibels, which will not affect the daily life of the family. Its lead - free stainless - steel faucet eliminates lead and heavy - metal pollution, ensuring safe and pollution - free water discharge in the last step.

With its advanced filtration technology and practical functional design, this under - sink RO water filter provides a strong guarantee for the drinking water health of modern families. It is expected to become a must - have appliance in many home kitchens, leading a new trend in healthy drinking water.
