Is anybody using either of these on-demand systems from future of cleaning, if so what are their thoughts about them.  Or can anyone recommend an alternative on demand system.

Thanks in advance

Looks like single DI,no good.

You don't have to buy a ready made.You can buy the filters and di vessels and strap them on a trolley.

And you can make it even much better by using sediment+Fibredyne filters and double DI.
