I want clean water.

When it comes to home safety, at first, everyone's concern was anti-theft, and later it became formaldehyde. Recently, many people backstage are talking about the problem of water use. In fact, it's not that we care more and more about our lives, most of them are forced by the environment. If the home is safe, who will take the trouble to study clean water? About domestic water, I checked the information for you and told you what I learned:

water filter

Let's talk about the water purifier first. There are two main places to use water, the kitchen and the bathroom. The kitchen is the key. Because drinking water is directly related to health, it is necessary to install a water purifier. At present, there are two kinds of water purifiers on the market: ultrafiltration and reverse osmosis (RO membrane). Ultrafiltration can hold hundreds, and reverse osmosis is more expensive, generally 2500+. It can be seen from the price that the two filtering effects are different.

Ultrafiltration can remove impurities such as rust, sediment, residual chlorine and odor in water, and retain the original mineral elements in water. The filtered water can be used for washing vegetables and cooking. Reverse osmosis filtration is more accurate, which can filter out minerals and heavy metal ions intercepted by ultrafiltration, and the filtered water can be directly drunk. Is that ultrafiltration or reverse osmosis? Feimojun prefers ultrafiltration, because minerals in drinking water are good for health, and reverse osmosis filtration is too thorough, so it is uncertain whether long-term drinking will affect health.

However, ultrafiltration may leave slight harmful substances, which should be boiled before drinking. While people in China are used to drinking hot water, it is estimated that few people can get used to drinking water from the tap. The installation of the water purifier is also very convenient. Generally, in the space under the sink, there will be room for installation in the renovated house.

Whole house water purification system

Some people have high requirements for the quality of life, and simple water purifiers can no longer meet the needs of water safety. Then you can consider the whole house water purification system, not only drinking water, but also washing and cleaning water. A complete whole house water purification system includes pre-filter, central water purifier, central water softener, terminal direct drinking machine and pipeline machine.

Prefilter

It is the first stage of water treatment, and its main function is coarse filtration to remove rust, sediment and large particles, thus protecting water pipes and prolonging the life of water-using equipment such as showers, water heaters and toilets.

central water purifier

Purifying the water in the whole house can not only remove large-particle impurities such as rust, sediment and suspended solids, but also remove residual chlorine, water-soluble metals, organic compounds such as pesticides and pesticides, carcinogenic substances such as trihalomethane and carbon tetrachloride, and retain trace elements and minerals needed by the human body.

Central water softener

Remove calcium and magnesium ions from water, soften water quality, make domestic water more comfortable, and prevent scale from blocking pipelines. The water softener is generally installed in the bathroom, because there are no calcium and magnesium ions in the water, which is not suitable for reference. Don't answer the kitchen.

Terminal direct drinking machine

On the basis of filtration by the central water purifier, the direct drinking machine can completely separate heavy metal ions, organic matter, bacteria, viruses, pesticides and so on. And retain the original trace elements in the water, so that the water can be directly drunk.

Pipeline machine

The water purifier has built-in filter components, which have three kinds of effluent: refrigeration, heating and normal temperature. It can be used to make coffee and milk tea, and can be drunk as soon as it is hot. Generally installed in the corner of the living room, study, bedroom and other leisure places.

In this way, as long as the water that can be touched at home is filtered layer by layer, there is no need to worry about unhealthy water use.

However, it is not cheap to install clean water in the whole house. Depending on the brand and family area, the price is between 2W and 3W. I can't afford to install it now, so I can reserve the position of water inlet pipe, drainage pipe and power supply, and then install it when I want to install it later.

That's all I know about the water purifier. As for what to pack at home, it depends on your economic ability and brand. I haven't studied it, but choosing a big brand is definitely more reliable and the filtering effect is guaranteed.
