Analysis: Are filter taps useful?
Water is the source of life, and the quality of drinking water directly affects our health. However, due to environmental pollution, the quality of the water we quote is getting worse and worse. Therefore, many families have purchased water purifiers. Purified water is limited after all, so nowadays faucet filters appear on the market; then, is the faucet filter useful? How often do you change the faucet filter? Let’s take a look at the editor below.
1. Adjust the acidity and alkalinity of water quality
The water quality itself has hardness, acidity and alkalinity. Partial acid or partial alkalinity are harmful to human health. After using the faucet filter, the acidity and alkalinity of the water quality can be adjusted.
2. Filter impurities
Most of the water used in cities comes from water purification plants. However, chemical substances such as bleach and disinfectant are used in the process of water purification, and a certain amount of chlorine or ammonia will remain after use. In the process of transporting tap water, it will enter our kitchen and enter our lives through water pipes. Iron water pipes will inevitably produce some rust after long-term use. For these substances, the faucet filter can be a good solution.
How often does the faucet filter change
As the saying goes, illness comes from the mouth. We drink water every day. The safety of drinking water is closely related to our health.
Many families now use drinking fountains with filtering function or bottled mineral water. However, in addition to these direct drinking water, do you use tap water when you cook, brush your teeth, wash vegetables, and wash dishes? To ensure drinking water safety, the problem of indirect drinking water at home should also be paid attention to.
Although the tap water flowing out of the faucet is guaranteed by the disinfection treatment of the water plant, it is often prone to secondary pollution during the transmission process.
The so-called secondary pollution refers to the pollution produced during the transportation of water pipes after the tap water is treated by the water plant. It is mainly the by-products of rust and other impurities from the aging of the water pipes and the by-products of the chlorine preparation of the water plant.
The problem of secondary pollution of tap water is common all over the world. In order to avoid and reduce secondary pollution, households in developed countries such as the United States and Japan will use faucet filters-a mobile simple filtering device. In our country, the use of faucet filters is ignored by many families.
The faucet filter has a limited adsorption capacity. After a period of use, the adsorbent will be saturated. Not only can it not remove impurities, but it will release new pollutants. Therefore, experts remind: When using the faucet filter, try to replace it once a month.
The advice of experts is to choose a water filter containing activated carbon and sponge (or non-woven fabric). Sponge and non-woven fabric can filter out visible impurities such as rust, while activated carbon can adsorb organic matter in tap water. Both of these filter materials are common in supermarkets, and the prices are relatively low.
