RO Unit

[ReEf BoSs]

I need to buy a RO unit where does everyone buy theirs ? As in best price to quality.

Is there really much of a difference from a 3 or 4 or 5 stage unit?
Its only going to be for a nano tank, so i don't think i need all the bells and whistles. I like reliable and simple, not just throwing money on what cost the most.It will be hooked up to a kitchen facet or garden hose depending on my mood and the weather.
Ideally it will only be used twice a month for less than a day each time if that means anything to the life span of filters/membranes good or bad.
Thanks

Aquasafe. Best price and its Canadian.

I started of using a 4 stage Kent RO/DI unit and it worked fine for years. Then it was time to switch out all the filters and resin and I came upon Aquasafe on Ebay. They had their 7 stage system with 3 years of filters for only $120 and free shipping (I haven't seen this offer since). This was about the same price as just a change of filters for my Kent unit so I gave them a go. The unit works okay but it comes with and adjustable flow valve where as most system come with a fixed flow restrictor matched to the membrane. So after some adjustment you get it dialed in. After awhile I found this was not a set and forget adjustment, it would suddenly stop producing much waste water then you would have to reset it, awhile later it was dumping tons of wastewater and little pure water. I also wasn't keen on 3 stages of DI resin. I ended up finding an inline line flow restrictor with a valve for flushing the membrane built in for the Aquasafe unit but ended up putting it on my Kent unit and went back using that one, changing the DI resin is simpler as well on the Kent unit. Any 4 stage ro/di unit will work well for you and give you great water, some have lots of features and better waste to filtered water ratios but in the end all will give you the same product.

I use the Vertex puratek 2 stage RO I 100gallons per day from J&L

I like it a lot (used for 3 years now still works like a charm)and it won't bust your bank account

I use this one and works well. The price was the reason I chose it, no issues so far with it.
