How long can I use the energy water bottle for?

Unlike similar products on the market with filters that last a mere 3 months, the energy water bottle’s pre-fitted filter lasts up to a whole year - depending on how often you use it. A replacement filter can be ordered for only more or less Php250 plus shipping charge. When no in use, the flask should be drained. Please refrain from leaving water in the flask overnight. It is imperative that the filters are given a rest, and should be drained and removed outside the flask to dry overnight.
