Here's what you want to know about water filter cartridges
Filter Encyclopedia
Healthy life, drinking water first water purifier has become a household necessity water purifier in bringing healthy and convenient drinking water at the same time, but also let some users confused: why just buy a water purifier, with a period of time will need to replace the cartridge?
In fact, there are different types of water purifier cartridges, different cartridges have different functions, each filter needs regular maintenance and replacement, so as to ensure the effect of water purification. The following is to share with you what are the common cartridges and their functions, as well as the recommended replacement time for each cartridge.
01 What kinds of water purifier cartridges are there? What are their functions?
The first level: PP cotton cartridge
PP cotton cartridge main raw material is polypropylene, also known as polypropylene meltblown cartridge, is the use of non-toxic odorless polypropylene particles made of tubular cartridges.PP cotton cartridge filtration accuracy of 0.5μm (micron) to 20μm ranging from the first stage of the filter is usually used as a water purifier cartridge. When the water flows through the PP cotton cartridge, the irregular pore size will be larger than the pore size of the material to intercept. PP cotton is mainly filtered out of large particles in the water, such as sediment, rust, colloids, insect eggs and other impurities, but also play a role in the protection of the subsequent cartridge.
The second level: granular activated carbon cartridge
Granular activated carbon is made of coconut shells, fruit shells and coal, etc., refined through a special process, the appearance of black irregular particles. Granular activated carbon set adsorption, filtration and interception, catalytic effect in one, with the removal of residual pesticides, organic matter, residual chlorine in the water, decolorization, deodorization function.
The third level: carbon rod activated carbon cartridge
Carbon rod activated carbon cartridge is the use of high adsorption value of coal activated carbon and coconut shell activated carbon as a filter material, and food-grade binder sintering compression molding. Carbon activated carbon cartridge can further adsorb foreign colors and odors in the water, chemical pesticide residues, residual chlorine and other substances, and at the same time to protect the RO membrane, to extend the service life of the RO membrane.
The fourth level: RO reverse osmosis membrane cartridge
RO is the abbreviation of English Reverse Osmosis, Chinese meaning reverse osmosis. The general flow of water from low concentration to high concentration, water once pressurized, will flow from high concentration to low concentration, that is, the so-called reverse osmosis principle: due to the aperture of the RO membrane is a millionth of a hairline (0.0001 micron), the general eye can not be seen, bacteria, viruses are 5,000 times as many as it is, only the water molecules and some of the minerals ions can be passed, and other impurities and heavy metals are discharged by the waste water pipe. Other impurities and heavy metals are discharged from the waste pipe.
RO membrane can effectively remove calcium, magnesium, bacteria, organic matter, inorganic substances, metal ions and radioactive substances in water, purified water crystal clear, sweet and sweet. In addition, reverse osmosis membrane element will produce waste water. Membrane elements that do not produce wastewater must not be reverse osmosis membrane.
The fifth level: after the activated carbon cartridge
Post-activated carbon cartridge is a new type of deep filtration cartridge, which is composed of selected coconut shell activated carbon with low heat fusibility adhesive. As silver atoms can sterilize and inhibit bacteria, some good activated carbon materials will be silver-loaded treatment for this reason.
As the last level of cartridge, the post activated carbon cartridge can improve the taste of water and inhibit bacterial regeneration, the water quality is purer, the taste is sweeter, so that the purified water tastes better.
How often should I change my 02 cartridge? How do I know to change the cartridge?
How often to replace various filter cartridges
A household RO reverse osmosis water purifier is generally a multi-stage composite, composed of PP cotton, activated carbon, front, RO, rear, etc. RO membrane is generally located in the fourth or fifth level of the position, the first few levels of the cartridge play a role in coarse filtration, and to a greater extent is also in the protection of RO membrane, so the first few levels of the replacement cycle is relatively short.
1 . PP cotton using meltblown filter cartridge made of polypropylene microfiber hot melt entanglement, generally used to intercept large particles of impurities, such as suspended solids in the water, sediment and so on. Replacement cycle is generally 3 months - 6 months.
2 . Activated carbon cartridge is divided into granular activated carbon (UDF) and compressed activated carbon, sintered activated carbon (CTO), the raw materials are mainly wood carbon, coal carbon, fruit shell carbon, petroleum coke, regeneration carbon and resin activated carbon categories. It is mainly used to adsorb residual chlorine, color and odor in water, and is usually used as the second and third level filter element of water purifier, and the replacement cycle is usually 6-8 months.
3 RO reverse osmosis membrane is mainly used to filter out small molecules of organic matter, bacteria, viruses, minerals, etc. in water. Service life and pretreatment cartridge (PP cartridge, activated carbon cartridge) and wastewater ratio, etc., generally 18 months -36 months.
How do I know I need to change the cartridge?
The following circumstances indicate that your water purifier should replace the filter cartridge:
1, the amount of water becomes small, after rinsing the amount of water is still very small, then it is likely that the water purifier cartridge in the “distress signal” that the RO membrane clogging.
2, the cartridge indicator color changes.
3, the TDS value of the filtered water to dozens.
4, the pressure of wastewater discharge in more than 6kg.
5, RO membrane use time more than two years.
03 What are the hidden dangers of not changing the core regularly?
1 spend more money
Water purifier cartridge from coarse to fine level by level filtration, each in its own way. If the former filter element is not replaced according to regulations, it will reduce the filtering effect or even failure, thus increasing the burden of the latter filter element. Originally only need to replace a cartridge, but now may need to replace the latter cartridge at the same time.
2 affect the use of effect, loss of machine life
Filter in the process of use, the more the surface of the pollutants, if not replaced in time, easy to be clogged, and then the water flow will become smaller, thus affecting the use of the effect and experience, but also loss of machine life.
3 breeding bacteria, endangering health
When the life of the cartridge reaches its limit, its surface may be adsorbed with a large number of organic matter, to provide conditions for bacterial growth, ultimately leading to filtered out of the water its bacterial content seriously exceeds the standard, at the same time, due to the removal of pollutants in the water cartridge has tended to be saturated with pollutants, unable to meet the requirements of water purification. Therefore, in order to better protect the family water safety, health, must be timely replacement of the filter.
Here Susan reminds all family members to remember to change the core on time to have a steady flow of healthy water ~!
