How to detect the quality of water purifier
As people pay more and more attention to the safety of drinking water, water purifiers have become a must-have appliance for many families. However, there are many brands of water purifiers on the market with varying quality. How to judge the quality of a water purifier has become a big problem for consumers. This article will combine the hot topics and hot content on the Internet in the past 10 days to analyze how to detect the performance of the water purifier from multiple dimensions and provide structured data for reference.
1. Core testing indicators of water purifiers
The quality of a water purifier mainly depends on its filtration effect, filter element life, water outlet speed, material safety and other core indicators. The following are specific detection methods:
| Detection indicators | Detection method | Qualification standards |
|---|---|---|
| filter effect | Use a TDS pen to test water quality (the lower the TDS value, the better) | Purified water TDS value ≤50ppm |
| Filter life | Check the filter replacement cycle marked on the product | RO filters are usually replaced every 1-2 years |
| Water outlet speed | Actual measured water output per minute (liters/minute) | Household RO water purifier ≥0.8L/min |
| Material safety | Check whether there is NSF certification or quality inspection report | Comply with national GB/T 30307 standard |
2. Analysis of popular water purifier problems (data in the past 10 days)
According to search data from the entire Internet, the following issues have been hotly discussed recently:
| Popular questions | Discussion proportion | solution |
|---|---|---|
| Is the water purifier filter element universal? | 35% | Need to match the brand model, third-party filter elements need to be cautious |
| Wastewater ratio of RO reverse osmosis water purifier | 28% | Products with a wastewater ratio of 1:1 or 1.5:1 are preferred |
| Water purifier noise problem | 20% | Check whether the water pump is aged and whether the installation is stable |
| Abnormal fluctuations in TDS values | 17% | It may be that the filter element fails or the RO membrane is damaged. |
3. Practical testing steps
If you have purchased a water purifier, you can quickly test its performance through the following steps:
1.TDS detection: Compare the TDS values of raw water and purified water. The larger the difference, the better the filtration effect.
2.Taste test: Purified water should be free of impurities and odor. If it tastes astringent or has an obvious odor, check the filter element.
3.Water volume test: Fill 1 liter of water and time it. If the speed is significantly lower than the nominal value, the filter element may be clogged.
4.wastewater observation: RO water purifier drainage should be clear. If it is turbid, the membrane element may be damaged.
4. Purchasing suggestions (based on recent reviews of popular brands)
| Brand type | Recommendation index | Advantages |
|---|---|---|
| RO reverse osmosis type | ★★★★★ | High filtration precision, suitable for areas with poor water quality |
| Ultrafiltration type | ★★★☆☆ | Retains minerals but cannot remove heavy metals |
| Activated carbon type | ★★☆☆☆ | Only improves taste, limited filtering ability |
5. Precautions
1. Replace the filter element regularly (even if the nominal life is not reached, it needs to be replaced if the water quality drops).
2. Avoid buying off-brand products without after-sales guarantee. 60% of recent complaints involve after-sales issues.
3. Pay attention to antifreeze in northern areas, as low temperatures may cause the filter bottle to burst.
Through the above methods and data, you can comprehensively evaluate the performance of the water purifier and ensure the safety of drinking water. If any abnormality is found during the test, it is recommended to contact the manufacturer or professional maintenance personnel immediately.
