How long can I keep these filter in storage

Not really sure -- we've had ours for a year (bought them at the time we bought the system) and so far so good.

I am considering this unit for my 2nd home and expect to use sparingly-- is the filter replacement dependent on time elapsed or amount of water used?

Hi, Thanks for your interest in our product. Please note the lifespan of our products relies on two factors: time elapsed and amount of filtered water, when either of these two dimensions is reached, cartridge replacement is required. If you have any other questions, please feel free to contact us. Enjoy the rest of your day! Kind Regards Mia Lauren Customer Service Rep

Am i correct in my assumption that this is not an nsf certified water filtration system?

They were going through the NSF testing process for a while, but now their website and the product description on Amazon states that it is an NSF 58 & 372 CERTIFIED water filtration system with NSF certified replacement filters.

Will these filters work with the G2 system?

Hi Steven, Thanks for your interest in our Waterdrop WD-G2-B Reverse Osmosis System. We are sorry to tell you that those three filters for the G3 system can not work with the G2 system. The G2 system has two composite filters, which are CF filter and MRO filter. Both of them will be in stock in April. Here is the purchase link of there two filters for your reference. CF: http://www.amazon.com/dp/B082D1VZ4P?ref=myi_title_dp MRO: http://www.amazon.com/dp/B082CZV16X?ref=myi_title_dp If you have any questions, please feel free to give us a call between the hours of 8:00 AM-5: 00 PM (PST), Monday through Friday at 1-888-352-3558. We will try our best to help you out. Thank you very much. Best Regards, Mia Lauren
