  • +How much water can be filtered/purified per day?

    The flow rates of the filters and purifiers are determined by a combination of four variables:

    • Head pressure (The distance from the top of the water to the filter)
    • Altitude (The higher the altitude, the slower the flow rate)
    • How clean the filter is
    • The filter itself (there are slight variations between filters)

    The PointONE Filter with a 1 foot hose (Model SP180) attached to a standard five gallon bucket at sea level is capable of filtering up to 295 gallons (1117 liters) of water per day. The PointZERO TWO Purifier with a 3 foot hose (Model SP190) attached to a standard 5 gallon bucket at sea level is capable of purifying up to 87 gallons (327 liters) of water per day. If you increase the head pressure by either lengthening the hose, attaching the filter to a larger container like a 55 gallon drum, or constantly keep the bucket full so the top of the water is as high as possible, this will increase the flow rate.

    To estimate the flow rate of your filter based on the altitude where you will be filtering water and the inches (or centimeters) of head pressure:

  • +How often do you have to clean or backwash the filter?

    The frequency of cleaning depends on how dirty the water is. With relatively clear water, backwashing may only be necessary every 1,000 gallons whereas with extremely turbid or muddy water, backwashing may be required every 10 gallons. Nevertheless, backwashing is an extremely simple process and takes only a minute.
