| water pollution incident | Filtration technology, heavy metal removal | ★★★★★ |
2. Working principle of central water purifier filter element
Central water purifiers usually use a multi-stage filter element combination, with different levels corresponding to different filtration functions:
| Filter element type | Filtering accuracy | Main functions | Replacement cycle |
|---|---|---|---|
| PP cotton filter element | 5-10 microns | Intercept sediment and rust | 3-6 months |
| Activated carbon filter element | 0.5-1 micron | Absorb residual chlorine and odor | 6-12 months |
| RO reverse osmosis membrane | 0.0001 micron | Remove heavy metals and bacteria | 18-24 months |
3. Answers to hot questions about filter element replacement
Based on recent frequent user questions, the following key knowledge points have been compiled:
1.How to tell if the filter element needs to be replaced?When the water flow rate decreases significantly, the water quality and taste change, or the water purifier alarm prompts, the status of the filter element needs to be checked in time.
2.Can different brands of filter elements be mixed?It is recommended to use the original filter element. Third-party filter elements may have differences in size or filtration accuracy, which will affect the purification effect.
3.Can filter cleaning extend life?The PP cotton filter element can be rinsed briefly, but cleaning of activated carbon and RO membranes is not recommended. Forcible flushing may damage the filter structure.
