At what intervals does the unit indicate that the filter needs to be replaced? Every 3 months or every 2 weeks? Is it possible to make a general statement? Since the unit itself decides when it needs to be replaced.... I would like to calculate how much I have to spend on filters per year. Thanks in advance Stefanie
