How to use pre-filter
The pre-filter is the first line of defense in a household water purification system. It is mainly used to filter large particles of impurities in tap water, such as sediment, rust, etc., to protect subsequent water purification equipment and extend its service life. The following is a detailed guide on the use of pre-filters, combined with relevant discussions in hot topics across the Internet in the past 10 days.
1. The function and principle of pre-filter
The pre-filter intercepts impurities in the water through physical filtration. The core components are mostly stainless steel filters or PP cotton filter elements. Here are common types of comparisons:
| Type | Filtering accuracy | Service life | Applicable scenarios |
|---|---|---|---|
| stainless steel filter | 40-100 micron | 3-5 years | Areas with hard water |
| PP cotton filter element | 5-20 microns | 3-6 months | High turbidity water source |
2. Detailed explanation of installation steps
1.Site selection: Priority is given to installation after the main valve of the household water pipe, and a drain outlet and operating space must be reserved.
2.Turn off water: Close the main valve and drain the remaining water in the pipeline before installation.
3.Connecting pipes: Use union nuts to fix the water inlet and outlet. Note that the direction of the arrow is consistent with the water flow.
4.test: After opening the main valve, check whether each interface is leaking.
3. Precautions for use
According to the feedback data from e-commerce platform users in the past 10 days, common problems focus on the following aspects:
| Question type | Proportion | solution |
|---|---|---|
| Water pressure drops | 42% | Backwash or replace filter element regularly |
| The interface is leaking | 35% | Check whether the sealing ring is aging |
| Poor filtering effect | 23% | Check if the filter is damaged |
4. Maintenance skills
1.Flush cycle: It is recommended to flush manually once a month. For automatic flushing models, keep the power supply open.
2.Filter element replacement: When the water output is significantly reduced or the water quality deteriorates, it should be replaced immediately.
3.winter protection: Antifreeze treatment is required when the ambient temperature is below 0℃.
5. Comparison of popular models
Based on the recent popularity of social media discussions, three high-profile products are listed:
| Brand model | Filtering accuracy | Flushing method | price range |
|---|---|---|---|
| A brand X3 | 50 microns | Double sided scraping | 500-600 yuan |
| B brand T7 | 40 microns | siphon recoil | 800-900 yuan |
| C brand P5 | 100 micron | Manual rotating brush | 300-400 yuan |
6. Answers to common misunderstandings
1.Myth: Higher accuracy is better: Actual selection should be based on water quality. Too high precision can easily lead to frequent blockage.
2.Myth: No maintenance required: Failure to rinse for a long time may breed bacteria and affect water quality.
3.Misunderstanding: Substitute for other water purification equipment: The pre-filter is only basic filtration and cannot remove microorganisms and chemical pollutants.
Through reasonable selection and use of pre-filters, household water quality can be effectively improved. It is recommended to check the status of the equipment every six months and adjust the maintenance plan in conjunction with professional water quality testing.
