The prices of different brands and types of water purifier filter elements are different.
1. The price of PP cotton filter elements ranges from a few yuan to tens or hundreds of yuan. The ex-factory price of this PP cotton filter element itself is very low, so there is no need to buy particularly expensive ones.
2. Activated carbon filter element, the price ranges from 20 to 30 to 300 to 400, which is slightly more expensive than PP cotton.
3. Ultrafiltration membranes, the cheapest ones range from tens of dollars to thousands.
4. RO membrane, hundreds to thousands of dollars.
The filter element should be replaced when its service life is up. If it is not replaced when the time is up, the water purifier will lose its function. The filter element replacement time is as follows: PP cotton filter elements generally need to be replaced every 3 to 6 months. The activated carbon filter element should be replaced about half a year. Ultrafiltration membrane filters last for 2 to 3 years. RO reverse osmosis membrane 2 to 3 years. Post activated carbon for more than 1 year.
The above data are the most ideal conditions, and the actual service life will vary depending on local water quality and frequency of use. Where the water quality is good, the filter element has a longer service life, but in places where the water quality is poor, the filter element wears out faster.
