Question:
We stay in Arizona a lot and I keep getting white buildup on faucets and shower heads. Will one of these systems fix that?

Expert Reply:
Hello Denise, for that kind of mineral buildup, you’ll want the AR3 Elite # GB59FR.
It includes the same 3-stage filtration as the Essential # GB39FR, but adds a water softener, which is what actually prevents that scaling. The softener is rechargeable with salt, so you can keep using it long-term.
The AR3 Essential # GB39FR filters well, but won’t help with hardness.
How long are you typically parked in one spot when you’re in Arizona? What areas do you like to camp in AZ?
