The Working Principle of Water Purifier: Reveal The Magic of Purification
Pre-filter: to the pipeline “wear” on a layer of solid armor
Pre-filter is like a loyal little guard, it is installed in the front of the family intake pipe, always vigilant to filter the water of large particles of impurities.
Imagine it as a miniature “sieve” that intercepts sediment, rust, suspended particles and other such large lumps so that they cannot enter our plumbing system.
Its filtration precision is generally between 5 – 100 microns, through the stainless steel filter or stacked filters, for the pipeline to wear a layer of strong armor, protecting the subsequent water purification equipment, to extend their service life.
PP cotton filtration: letting the water “pass through” the layers of fine mesh filters
PP cotton cartridge is like a super “Filter Man”, it is made of polypropylene fiber material made of meltblown cartridge, can effectively remove smaller particles of impurities, colloids and suspended matter in the water.
When the water passes through these layers of fine filters, it is like traveling through a mysterious labyrinth, those small particles of impurities are intercepted on the surface of the cartridge, making the water clearer and purer.
Its filtration precision is generally in 1 – 5 micron, and low cost, good filtration effect, replacement is also very convenient, like a small guard on standby, every 3 – 6 months will take the initiative to “change the guard”, to ensure that the filtration effect is always the same.
Activated carbon adsorption: with “magic” to retain the odor and impurities in the water
Activated carbon cartridge is like a magical “magic wand”, it has a rich pore structure, like a small sponge, able to adsorb foreign colors, odors, residual chlorine and a variety of organic matter in the water.
When the water passes through the activated carbon cartridge, it is like a gentle iron absorber, adsorbing those molecules with odor and impurities on its own surface, making the water fresh and sweet.
Common activated carbon includes coconut shell activated carbon, fruit shell activated carbon and coal activated carbon, among which coconut shell activated carbon has particularly good adsorption performance.
However, the activated carbon cartridge also needs to be replaced regularly, otherwise it will lose its effect after it is “full” of impurities, and may even cause secondary pollution.
Reverse osmosis filtration (RO): like a super “sieve” like filtering out pure water
Reverse osmosis technology is simply a super “sieve”, which relies on the semi-permeability of the reverse osmosis membrane, under the action of pressure, so that the water from the high concentration side to the low concentration side of the permeability.
Imagine that the reverse osmosis membrane is like a fine filter, intercepting dissolved salts, heavy metal ions, microorganisms and other impurities in the water, and allowing only water molecules to pass through.
Its filtration precision is extremely high, reaching 0.0001 micron, almost all the impurities in the water can be filtered out, producing high quality water close to pure water.
However, this process produces a certain percentage of wastewater, like a small “side effect”, and the wastewater ratio is generally around 1:2 – 1:3.

Ultra-filtration filtration: the “little secret” of retaining beneficial substances in water
Ultra-filtration water purifier is like a smart “little guardian”, it adopts ultra-filtration membrane for filtration, the filtration precision is generally between 0.01 – 0.1 micron.
It is capable of removing large organic molecules, colloids, bacteria and viruses from water, but has a relatively limited effect on the removal of dissolved salts and heavy metal ions.
Its advantage is that it does not require electricity, relies on water pressure for filtration, and has a large water output and no wastewater discharge.
Like a small “magic box”, it retains the minerals in the water that are beneficial to the human body while filtering, making the water both healthy and delicious.
