Families only solve the problem of drinking water. Generally, they choose a filter water purifier, and then choose different filter elements of the water purifier.
Filter element type Water purifier filter element includes activated carbon filter element KDF, ultrafiltration membrane, RO reverse osmosis, etc. It is said that the filter elements of hollow fiber ultrafiltration membrane (UF) and reverse osmosis membrane (RO) are changed every three years. The water quality in the north is hard and suitable for reverse osmosis water purifier, while the water quality in the south is soft, so ultrafiltration water purifier is generally used.

The shell is durable, beautiful and generous, and will not produce any toxic and harmful substances. However, the use will produce scale, and descaling is more troublesome. It is heavy, has serious heat conduction and is easy to burn.
3. Ceramic electric kettle
Exquisite appearance, many colors and high grade. Non-toxic and harmless, easy to clean. However, the ceramic products themselves are fragile, so we should handle them with care, otherwise it will damage the pot body and affect the appearance. The price is more expensive.
