This is a best quality system. I order 2 system from them in one moth. One of them has problem with the tank, the support team call me 2 hours after I was send the email, and the replace tank came three days after. Excellent tech support, and good price. Extra filters will save for another year. Fast delivery, Very easy installation. The system came with white housing and I request them to change all for clear housing. They change it with no extra charge. I can see all the filters though the clear housings. The water came into the first housing. When I see the filter dirty, I change this filter more frequently to keep other filers last longer. Thanks

I’m rating this 5 stars because the unit is as good as you could get for the money. Granted, for more money you could have more expensive fittings, etc, but they are really not necessary unless you are going to be constantly moving and reassembling.

I’ve just finished installation of your 5 stage home drinking reverse osmosis system and I have a few suggestions for improvement. It looks like the faucet included in the package is different than the one in the instructions. I like the upgrade, but it would be nice if you included a compatible quick connect adapter. The Quick Connect adapter that was included (pictured on the right) has threading that is too large to fit on the faucet. The packing nut attachment doesn’t work well with plastic tubing.

I’ve used a reverse osmosis filter for the past 13 years. Mine finally quit making water and the manufacturer wasn’t being helpful. I was going to start replacing parts until I found the bad one when I saw the price on this unit. It not only works as well as my much more expensive old unit, but it came with a spare set of filters. I could not be more pleased. I have mine mounted on a wall near my hot water heater because it is more convenient. Since I was replacing an existing unit I didn’t have to tap a supply line or drain.

the resulting water tastes very good. it comes out with alot of very fine bubbles making it look cloudy but when the bubbles dissipate the water is clear and crisp and clean and tastes great!

No more bottled water!

Well, we won’t be buying bottled water anymore! Our water now tastes better than the bottled water I was buying. This system will help save us money since I was buying 6 cases of water a month.
