Need a techy person to really explain but in my simple terms its this.

RO - Using filters and membranes the tap water is purified to a minimal TDS reading and then finally polished of using a DI vessel.

The benefits are the water is produced at the cheapest cost.

Downside is unless you have a static tank your vehicle is stood overnight filling up. Ours takes 12 hours.



DI - A cannister that basically you send tap water through that then gets reduced down to 000 TDS

The benefits - Quick fill time, mobile in van

Downside - COST !!!! The more you use it the quicker it will be expired. I used a 12.5 ltr DI vessel and was averaging 1000 litres at 000 before the levels started to rise. Bag of 25kg Resin is about £60 - £80

Hope this helps Mark.

Best wishes,

Trev

You will need a RO Mark

With a di your water is so dirty you will use 100€ worth of resin a month

A RO will allow you to produce the water at home

Although you will need to produce a bloody lot if the glass is a dusty/sandy as it is here..
