BLUONICS5 Stage Undersink Reverse Osmosis Water Systems for Drinking Water. NSF Certified Membrane. RO Home Purifier with 4G Tank and One Set of Filters

I paired this 50GPD Bluonics 5 Stage RO system with a ERP-500 permeate pump and it definitely exceeded my expectations! I went from 600+ppm to 10-20ppm. Color tubing is a really nice plus for a neat install. I highly recommend this if you are having water quality issues.

I like the way the r/o system is put together the color coded lines help a lot. All connection are push to connect, comes with all faucet line adapters, a faucet, and tank. The bad is the faucet adapter shut off is poor design where the 1/4 line connects and I had a leak on the pressure tank valve where the blue turn handle is.

The first RO unit I purchased several years ago was from ISpring, no complaints, OK filter. The next I bought is this little jewel from Bluonics. Whats the difference?? The small details. Better design, one piece filter housing manifold rather than 3 separate units screwed onto a support, integrated flow restriction unit, built in filter flush, higher quality filter elements and membrane. The ispring unit delivered a consistent 90 to 100 ppm water (down from 400 ppm feed water. Bluonics consistently provides 12 to 18 ppm day in, day out down from 400 ppm feed water (same source)One year in, and zero complaints. Very good quality, install and run. I have an aquarium and do weekly water changes, so the load on the unit is an additional 10 to 15 gallons weekly. Conductivity running in the 14 to 20 ppm range.

Product leaked and constantly drained and wasn’t worth it for me I lost the box so I couldn’t return it

This filters the water well. Great taste. The only issue is that the tank is a little smaller that our liking. We have a big family and sometimes we drain the tank to quickly. It takes time for the water to be filtered to refill the tank. I would suggest a bigger tank.

I received the system as advertised. Good system for the price. The only thing missing from the one I received was the 3/8" to 1/4" faucet adapter, so I just had to use my old one.

Replaced my old 29 year old RO system with this unit, easy installation, I didn’t need the instructions although they are very complete and easy to understand, love the clear filter housings.

The RO membrane is not good. Water doesn't flow through. I read one of the review about the exact problem, but chose to ignore it, and now it got me. Please send me a different RO membrane.Update: Got it to work, for now. I'm still concerned about the flushing go every time I change filters.Manual is not clear on the steps. They give caution about flushing, but make it a warning instead of one step.Page 10 last line mistake Red line to Tank.Did not indicate which position is On or Off for the front blue valve (for flushing).Flushing step does not indicate output water is clean from where, faucet or waste line.Flushing is a hassle. Never had a system that I had to do flushing before installing RO membrane. Does that mean every time I replace filter, I must remove the RO membrane and do a flushing and then reinstall?Like I mentioned above, after a day leaving the tank on, I do the tank flush and found out there's no water at all.I'll leave my 2 stars here until seller respond.
