How ToJudge The Purification Effect Of Water Purifier
In daily life, water purifiers have become important equipment for many families to ensure drinking water safety. But how to judge the purification effect of the water purifier? Here are a few ways to help.
Observe water quality appearance
Clarity: The purified water should be clear and transparent, with no suspended matter, sediment or turbidity. The purified water can be poured into a transparent container and observed in front of the light. If the water is clear and there are no obvious impurities, the purification effect is better.
Color: Normal purified water should be colorless. If the water appears yellow, brown or other abnormal colors, it may be that the purification effect of the water purifier is not good, or there are other problems.

Detection of water quality index
TDS value: TDS (Total Dissolved Solids) is the total dissolved solids in water. A TDS detector pen can be used to measure the TDS value of the water before and after purification. In general, the TDS value of purified water will be significantly reduced. If the TDS value decreases greatly, it indicates that the purification effect of the water purifier is better.
pH value: The pH value of water reflects the pH of water. Normal drinking water pH is generally between 6.5 and 8.5. You can use a pH test strip or a pH meter to test the pH of the purified water. If the pH value is within a reasonable range, it means that the water purifier is more appropriate to adjust the pH of the water.
Residual chlorine content: Tap water usually contains a certain amount of residual chlorine for disinfection. Residual chlorine detection reagent or residual chlorine detector can be used to detect the residual chlorine content of water before and after purification. The residual chlorine content of the purified water should be close to zero, and if the residual chlorine content is significantly reduced, it indicates that the water purifier has a better removal effect on residual chlorine.
Taste and smell
Taste: The purified water should taste fresh, sweet and odorless. If the taste of the water is not good, there is bitter, salty or other odor, it may be that the purification effect of the water purifier is not good, or the filter element needs to be replaced.
Odor: Normal purified water should have no odor. If the water has a pungent smell, such as chlorine, fish or other odor, it indicates that the purification effect of the water purifier is not good, or there are other problems.
Check the status of the filter element
Filter life: the filter element of the water purifier has a certain service life, and when the filter element is used for too long, the purification effect will gradually decline. You can understand the service life of the filter element according to the instruction manual of the water purifier, and replace the filter element regularly.
Filter element appearance: When replacing the filter element, you can observe the appearance of the old filter element. If there is a large amount of dirt, impurities or discoloration on the surface of the filter, it indicates that the purification effect of the water purifier is better, and the filter element has played its due role.
Refer to the report of professional testing institutions
If there is doubt about the purification effect of the water purifier, the purified water can be sent to a professional testing institution for testing. The testing institution can conduct a comprehensive analysis of the indicators of water and issue a test report. Through the test report, you can understand whether the purification effect of the water purifier meets the national standard.
In short, judging the purification effect of the water purifier can be comprehensively considered from the appearance of the water quality, the water quality index, the taste and smell, the status of the filter element and the report of the professional testing institution. Only by choosing a water purifier with a good purification effect and regularly maintaining and replacing the filter element can we ensure the safety and health of family drinking water.
