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.

Peace - OGH
