Question:
I’m looking at the off-grid system and had two questions - how long does the battery last on a single charge, and are replacement filters easy to find?

Hey Ryan, great questions!
The ARX+ Off-Grid water filter for RVs # GB54FR is rated for about 90 gallons of water per battery charge, which is more than enough for most RV setups. If you find yourself pumping more than around 90 gallons of water per day (which would be a LOT!), then it does come with a few charger options such as cigarette outlet in car, 12v battery connection, or AC outlet.
As for maintenance, yes - replacement filters are readily available. The filter pack # GB27FR comes with 3 replacement filters for the system, so you can swap one out quickly and keep it running like new. Average filter life span is 3-4 months according to Blue Tech, so this 3 pack would get you by for around a year.
Are you planning to use it as your main water source off-grid, or more as a backup when you run low? What kind of off-grid camper do you have?
