How often does the filter cartridge of water purifier change

1. PP cotton filter element

The melt blown filter element is made of polypropylene superfine fiber by hot melt entanglement, which is generally used to intercept large particles of impurities, such as suspended solids and sediment in water. The replacement cycle is 3-6 months.

2. Activated carbon filter

Through high temperature, compression, sintering and other steps, coal, sawdust, fruit shell and other raw materials are transformed into active factors to adsorb the sediment. It is generally used to adsorb different color and peculiar smell in water. The replacement cycle is 6-12 months.

3. KDF (copper and zinc alloy) filter element

This kind of filter element is mostly used in central water purifier to remove chlorine and heavy metals in water by oxidation-reduction. The replacement cycle is about 12 months.

4. EM-X ceramic filter element

EM-X ceramic filter element controls the pH value of water by releasing trace elements. The replacement cycle of this filter element is long, generally 5 years.

5. Reverse osmosis membrane (RO)

The pore size of RO membrane is 260000 times that of hair. In addition to clean water molecules, other bacteria, viruses and heavy metal ions are difficult to pass through, and the filtration effect is very strong. Generally, the replacement cycle of this filter element is 2 years, but it needs to be tested by TDS test pen. If the TDS test pen reading is maintained within 10 ppm, it can be used normally.
