You should replace the water filter cartridge in time, which is a guarantee for safe and healthy water. Each water filter has its own life and you need to replace the filter cartridge on the basis of knowing their life.
Some common water filter cartridges: PP water filter, activated carbon water filter, filter membrane (microfiltration membrane, ultrafiltration membrane), reverse osmosis membrane (RO), etc.
PP water filter: It can filter large particles such as suspended solids and sediment, saving water and being cheap; but it can't effectively filter small particles.
Activated carbon water filter: It can filter toxic compounds, solve organic pollution and odor problems, and be used for pre or post-treatment of filtration; however, when water temperature is high and water alkalinity is high, its adsorption capacity will be affected.
Membrane (microfiltration membrane, ultrafiltration membrane): The microfiltration membrane has large voids, removes large particles such as sediment and rust in water, and is used in front of ultrafiltration membrane and reverse osmosis membrane to prolong the service life of the subsequent membrane. Ultrafiltration precision High, capable of filtering small molecules such as bacterial viruses and organic matter, and retaining mineral elements.
Reverse osmosis membrane: It can remove heavy metals, small molecular organic substances, bacterial viruses and other substances in water, but the waste water is large in output and expensive.
When do you change the water filter cartridge?
Check the color of the water filter cartridge. For example, the pp water filter, if the color of the filter cartridge becomes black or brown, the filter element needs to be replaced.
Check the time. The commonly used water filter cartridges are used for 6-12 months, but some filter cartridges such as the ro membrane are used for 2-3 years.
