RO-DI Unit costs?

Featured Replies

I am looking to buy a RO-DI unit, what does a brand new 6 stage unit go for?

is $250 cheap it comes with tap adapter, 25 feet of tubing, pressure gauge and shut-off float valve? :D

just check when the cartridges were last changed, as they do wear out over time and replacement may up the price in the big picture, but still, that is cheeeep! :thup:

Having said that, 6 stage with full working cartridges should end up with 0-1ppm TDS, So insanely pure!

Its brand new

Check the size and litres rating of the pre-filters. Add the filtered water per day + permeate waste together as this will be the total water going through the prefilters.

It will give you some idea how long they will last. Check what they cost to replace and you'll get some idea of the running cost. Membranes last for a very long time if you have good quality prefilters.

Some of the cheap units used specialised pre and post filters and because they're proprietary they cost an arm and a leg to replace...

I ended up replacing my pre and post filters with standard readily available units with a much larger capacity and it lowered the running costs to approx 25% of the proprietary parts. It also gave me a much better selection of filters to use. As long as the unit already has standard filter housings it will be cheap to run.
