【Long Durable Life Span】: To ensure your machine operates at peak performance, we recommend replacing the black carbon filter every 5,000 gallons per pair and the white fluoride filter every 1,000 gallons per pair (Filter performance may vary based on local water conditions). Attention: If the local water quality is hard (high mineral content) or turbid, it may be necessary to shorten the replacement interval (such as 500-1000 gallons in advance).If there is a high content of fluoride or other chemicals in the water, it is recommended to replace it every 800 gallons to ensure filtration efficiency.Please note that you have to totally submerge the carbon filter about once a week in order for the drip system to siphon properly

• 【Attention to installation steps】:First, Please connect the faucet to flush the black carbon filter and fluoride filter for at least 1-3 minute before use. In an effort to wash loose activated carbon and natural mineral synthesis material powder away in advance.
