Ive had mine over a year. Sits on my counter when not in use. No need to store membranes they last 3 years or so under normal conditions. Only things that need replaces is sediment filter carbon block and di
resin. Comes with color changing di
resin and refillable cartridge so no guess on when to replace. Sediment and carbon block may need replaced every 3-6 months depending on usage and how dirty you tap is. Filters are not expensive. Membrane is most expensive at about 60 bucks or so but havnt had to change it yet and dont plan on it for another year or so. Got a $20 TDS
meter from brs too. Couldnt ask for better for the price. Great reviews.
