1. Understand the water quality
Before choosing a water purifier, you must first understand the local water quality status. Information such as the hardness of the water quality, the pH value, and the types of harmful substances contained in it are very important to choose a water purifier. You can self-test by purchasing a water quality test kit, or you can consult your local water company or a third-party water quality testing agency.
Second, the type of water purifier

1. Activated carbon filter: Suitable for removing residual chlorine and organic matter in water to improve taste.
2. Reverse osmosis (RO) purifier: It is suitable for water sources with high water hardness, heavy metals, bacteria and viruses.
3. Ultrafiltration (UF) purifier: It can remove suspended solids, bacteria and most viruses in water, but cannot remove dissolved heavy metals and hardness.
4. a water softener: It is mainly used to solve the problem of water hardness and is suitable for hard water areas.
5. Ultraviolet (UV) sterilizer: Suitable for clean water sources that have been filtered but need to be sterilized.
Third, the core technical parameters
1. Filtration accuracy.
1) Micron (m) class: It can remove large particles such as sediment and rust.
2) Nanometer (nm) scale: It can filter out smaller particles, such as bacteria.
3) Reverse osmosis RO membrane: Usually has 0The filtration accuracy of 0001 microns can remove more than 99% of pollutants.
2. Water output.
The water output refers to the amount of water that the water purifier can treat per hour, and the appropriate model is selected according to the household water consumption.
3. Filter element life.
Filter replacement intervals are also a factor, as long-life filters reduce replacement frequency and maintenance costs.
4. Performance and certification

Get feedback on the use of the product through the Internet, family and friends, and other channels. User reviews can be used as a reference for actual use results.
The selection of household water purifiers needs to comprehensively consider many factors such as water quality, water purifier type, technical parameters, performance certification, budget range, design and installation needs, maintenance services and user evaluation. After careful comparison and consideration, you can choose a water purifier that suits your needs and enjoy safe and healthy drinking water.
