What is a reliable RO filter? I see a million of them on Ebay, but the prices vary so much, I'm sure some are quality and some are junk... Can anyone reccommend a good one

Most all the outside parts are the same for most companies. The differences is in their set-up (filter array), and the quality of their filters inside the cartridges.
For the actual RO membrane, you want to be sure you get a DOW FilmTec membrane. Their 50gpd and 75 gpd membranes have a 97-98% rejection rate, which is the best in the biz. Get a 75gpd and you'll make about 3 gal an hour.
The best set-ups have a Sediment filter first, then Carbon, then another carbon, then to your RO membrane. Having dual carbons really protects the membrane from chlorine and chloramines, the two biggest killers of membranes.
The filter array (micron sizes) I recommend are:
10micron sediment filter, 5 micron carbon, 1 micron carbon, RO mem.
Try to avoid places that sell units starting with a 5micron sediment or less....they simply clog faster and you'll pad their pockets buying replacements.
Also, get a handheld TDS meter with any unit you get. This will allow you to test your source (incoming) water, and output to be sure the membrane is working good and will help you know when to replace filters.
Hope that helped some.
If I had to recommend a company to go with, it would be thefilterguys.biz
They have systems right at $125 that kick major butt. And their service is bar none the best I've ever experienced.

I checked it out and I wasn't too impressed with the specs for the cost compared to other models.

like i said....other models cost less.... but then again...they also waste more water.
you pick

I'm taking a huge guess here but I think u asked where to get a RO filter and how they work. Get one on EBAY, they work by hooking up to your homes water supply and cleaning that water. If u are talking about something else, sorry u threw a lot of jibberish in there....

I'm learning about these so my arguement may be irrevelant, I just want to get the most bang for my buck in the long run. LB your machine gets out between 95- 98% of toxins, etc..., I found a portable Aquarium RO filter that claims 99.9% (0ppm) u think that will make a difference?

lol.... im getting 000ppm from my 'treated' water....

one of what?

The only reason I didn't think u would be is because the company only claims 98%, most places I see claiming that also claim about 15ppm... The aquarium ones seem to have the best rating, but if u are getting 0ppm I'm not going to go by that anymore...
How long have u had it? What is the efficiency of the filters, does it take standars replacements? It sounds like u have a good system to me.

well im not sure....it could be the fact that i have low ppm inlet/input water?
i havent had the unit for too long.... a little over 2 months? im not sure about filters and such. im pretty sure it takes standard replacements....if not ill gladly pay for special filters!
