Level 1: PP cotton: removes various visible substances/dust and impurities from tap water.
Second and third stages: Pre activated carbon: Some low-end water purifiers also use PP cotton in the third stage, which removes chlorine and organic impurities with carbon. It can also absorb the odors, colors, and odors produced by organic compounds in water.
Level 4: Ultrafiltration or reverse osmosis membrane: The membrane is capable of removing bacteria, viruses, spores, and other substances from water.
Level 5: Post activated carbon device: further improves taste and removes odors.
Most water purifiers adopt a progressive structure based on the principle of blocking screen filtration, consisting of multi-stage filter elements connected in series from beginning to end. The precision of the filter elements is arranged in order from low to high, in order to achieve the distribution and interception of pollutants by multi-stage filter elements, thereby reducing filter clogging, manual sewage discharge, disassembly and cleaning, and extending the cycle of filter element replacement. There is also a new design concept that applies the principle of separation and circulation to a self-cleaning structure. Its design idea is no longer to provide as much space as possible for storing dirt and grime, but to adopt the principle of separation and separate a small part of clean water, while also allowing the raw water to flow as usual, so that the dirt can be carried away with the water flow in a timely manner, achieving the goal of preventing water from rotting. This not only purifies the water, but also prevents or reduces the sedimentation of pollutants inside the machine, avoiding secondary pollution and greatly reducing filter loss. The water quality is better, safer, energy-saving, and low-carbon.
