Fixed Water Filter Kit For Under Sink In DIY Camper Van Build - RAM ProMaster

Published 03/24/2026

Question:

We’re upgrading our van build Ram ProMaster and want clean water at the sink for cooking and brushing teeth. Is there a way to filter just inside the van instead of setting stuff up outside every time?

Hey Chris, yes - that’s exactly where the Blu Technology SOLO filter # GB64FR shines.

It installs directly into your water line inside the van usually under the sink, so everything coming out of your faucet is filtered without any setup at camp. It’s compact and uses a 0.2-micron filter, so it’s a big upgrade over the basic inline options.

A lot of van builds go this route to keep things simple and self-contained.

Are you pulling from a fresh tank with a pump, or planning to hook up to city water sometimes too?
