Bests & Worsts Reviews from Amazon

My old RO filter (with UV) was not working right, even after replacing all the filters. So I was looking for a new RO system with good reviews and decided on 2 systems: Tap Master TMAFC Artesian Full Contact Reverse Osmosis with Alkaline by Perfect Water and iSpring 6-stage with RO Alkaline. The Tap Master had tons of great feedback, but so was iSpring (the non-alkaline model). The only reason why I ended up purchasing iSpring was the price. DAY 1 The system came in a well packaged box and I found everything easily including some spare parts for future use, which I appreciate. Fittings and pipes were included. All I need was the tools (wrench, scissors, etc) and a Teflon sealer that I got from Home Depot. I noticed a little trace of water and I found out that iSpring did a real test for quality control so that's a good thing. Installation was not hard, but it took me 45-60 minutes because I had to make sure that all fittings were tight and I also labeled the in/out just for future references, steps that most people won't do or not required to get the system up and running. The manual is clear and upon my purchase, the seller emailed me a youtube link that shows how to install it. Once everything was installed, I ran the water for about 10-20 minutes just to flush the system. I used HM Digital TDS-EZ TDS Water Quality Tester and got 150+ PPM (parts per million) in the beginning, and got better as I continually ran the water within minutes to as low as 20 PPM. I also tested a very popular bottled water that I like, and it showed the same 20 PPM with similar taste, which is great. After about an hour or two, it seems to stay within the 15-45 PPM range. Note on PPM: 0-50 PPM = ideal water 50-100 PPM = carbon filtered water 100-200 PPM = hard water 200-300 PPM = average tap water 300-400 PPM = high total dissolved solid (TDS) 500 PPM = US EPA's high contaminant level I've run it off and on for a few hours now and saw no leak. Everything works great. The water quality is crisp and better yet, the Alkaline level is better than just an ordinary RO (alkaline has many benefits and will help you detoxify your body naturally). DAY 2 Tested the water often and I get 20-40 PPM. Water came out with less bubbles. DAY 3 As of now, the PPM is constantly in the low 20s with very little bubbles. This system runs very quietly and I've never heard any noise from it. I will update this review if I see some degradation in quality other than normal wear/tear or scheduled filter change (which is recommended every 6 months for some, 1 year for the other). Overall, I am happy with the quality and most importantly, I have a good, clean and great tasting water again. I will not have any problem recommending this system to anyone.
