“Tap water can be drunk by boiling, why spend a lot of money to install a water purifier?” “I heard that the water purifier can filter heavy metals, is it true?” “There are so many types of water purifiers, in the end how to choose?” The controversy about home water purifiers never stops. Some people think it's an IQ tax, while others regard it as a “life-saving device”. Today we are here to uncover the truth about water purifiers, and take you to understand the full set of logic of home water purification system!
01 Why do you need a water purifier at home?
You think that the water factory treated water can be drunk directly? In fact, from the water plant to your faucet, the middle of the way may be “crisis”. 1:
1. aging pipes: corroded metal pipes may leach lead, rust;
2. secondary pollution: community water tanks are not cleaned in time, breeding bacteria;
3. residual chlorine: the chlorine used to disinfect tap water may produce the carcinogen trichloromethane;
4. Water hard scale: high calcium and magnesium water in the north is prone to scale, injuring water heaters and clogging showerheads.
The core role of water purifier:
✅ Intercept sediment, rust and other impurities visible to the naked eye;
✅ Adsorption of residual chlorine, foreign color and odor;
✅ Filter heavy metals (lead, mercury), antibiotics and other harmful substances;
✅ Soften water quality, extend the life of home appliances;
✅ Realize the “freedom of drinking water”, say goodbye to bottled water.
02 How does the water purification system work?
A complete home water purification system, usually consists of 4 passes. 1:
1. The first pass: pre-filter Function: Intercept sediment, eggs, rust and other large particles of pollutants in the water pipe.
Location: installed after the household water meter.
Features: no need to change the core, regular manual flushing to protect the subsequent equipment.
2. Second level: central water purifier (optional)
Function: Improve the taste of water quality.
Applicable families: families with high requirements for living water.
3. Third pass: RO reverse osmosis water purifier (core!)
Function: Use 0.0001 micron RO membrane to filter bacteria, viruses, heavy metals, etc. and produce direct drinking water.
Key point: need to energize, discharge waste water, but the filtration accuracy of up to 99%, mothers and babies can drink directly!
4. Fourth level: pipeline machine
Function: connected to RO water purifier, 3 seconds of quick heat, realize “ice water/warm water/hot water” freedom.
03 Do you need to install a water purifier in your house?
3 self-test methods
1. Look at the kettle: the more scale, the harder the water. 2;
2. smell: after receiving the water to stand for 5 minutes, smell the pungent smell of chlorine indicates that the residual chlorine exceeds the standard;
3. Check the water quality report: in the local water authority website to check the TDS value (total dissolved solids), more than 200 recommended installation.
Key populations are recommended to install:
🔹 home with infants and young children or pregnant women;
🔹 old neighborhoods, high-floor households;
🔹 local industrial pollution is more serious areas.
04 Ultrafiltration VS reverse osmosis, which one to choose?
Type Ultra-filtration water purifier
Filtration precision: 0.01 micron
Can remove scale No
Whether to energize No
Applicable Scenario Water quality is good in the area
Type RO reverse osmosis water purifier
Filtration precision: 0.0001 micron
Can remove scale Yes
Whether electrified Yes
Applicable scenes Poor water quality, the pursuit of direct drinking
Conclusion: RO reverse osmosis for direct drinking, ultrafiltration for domestic water improvement only.
05 Guide to avoid the pit: 3 common misconceptions
1. Myth 1: “Water purifiers waste water!” Truth: RO machine wastewater can be recycled to mop the floor, flush the toilet, the actual loss <2 yuan / day.
2. Myth 2: “Installation of water purifier is very troublesome!” Truth: Kitchen RO machine occupies half of the cabinet, the installation of 2 hours to get it done. 3. Myth 3: “Imported cartridges are reliable!” Truth: Domestic Dow RO membrane technology is mature, the cost of core replacement is lower.
Summarize:
Water purifier is not a necessity, but a plus for a healthy life. Instead of obsessing about “whether to install”, why not spend 20 dollars to buy a water quality testing pen to check. If the water quality is not up to standard, the cost of a RO reverse osmosis water purifier ≈ a cup of milk tea money every day, but can change the whole family drinking water safety. After all, save what can not save health, RIGHT?
