Hi, Today preparing to install this FreshPure Energy Water System.
4 pieces filter built-in the box. If you want to know more about filters detail. (Reference Page)
Extended pre-filter is ceramic candle, filtering 0.9 micron. Cleaning every 2 weeks to 1 month.
Connect the 2 way adapter valve to faucet for water supply.
And then connect inlet & outlet piping.
If you don’t know how to install it, you can refer this installation guide.
Many certified of this Freshpure energy water system.
