    How often should I replace the filter? Can I replace it by myself?

    The D4 RO system only requires replacement once a year. You don't have to estimate when to replace your filters. It's very easy for you to complete the replacement by opening the front panel and removing the old filter.

    Does the system need the electricity to run?

    Yes, the Waterdrop RO system need electricity.

    Can the reverse osmosis system be connected to the refrigerator so the ice is filtered as well?

    1. Generally speaking, yes, The RO system can be connected to your refrigerator.
    After completing the registration online, you could choose the accessory kit, which will help you connect the RO to your refrigerator/ice maker.
    Since different refrigerator/ice maker has a various requirement of water pressure, it's not possible for our RO system to provide them all.
    Connection under mismatched circumstances may result in many problems, including but not limited: slow ice making, frequent start-stop issues, etc.
    Therefore, it's NOT recommended to connect the RO system to your refrigerator/ice maker.
    2. To determine if the RO's outlet pressure is enough to be connected, you may need to acquire the refrigerator's pressure requirement first, which can be found in its user manual.
    For your reference:
    RO's outlet pressure: ca. 35 psi

    What does Pure to Drain Rate mean?

    The reverse osmosis water filter relies on a semi-permeable membrane to filter out impurities from drinking water. When the tap water is compressed through the RO membrane, it produced pure water and waste water. The ratio of pure water to waste water is called wastewater ratio. 1:1 wastewater ratio means 1 gallon water is wasted per 1 gallon purified, and 2:1 wastewater ratio means 1 gallon water is wasted per 2 gallon purified. The higher the wastewater ratio is, the less waster water produced during the filtration process. During the use of RO water filter, the actual ratio might be lower than the labeled, depending on many factors such as water quality, pH, pressure and temperature.
