Review: PUREDROP - BEST ALL AROUND, GREAT PRICE, GREAT SUPPORT & A HIGH QUALITY RO SYSTEM - Wow Unbelievable. after 4 years - update. 2024. I called and talked with Nick again who provided the VERY BEST customer service I have ever gotten in my entire life. He answered the phone and within minutes my small install problem was solved and he is sending the part I needed at no charge. If you are looking for the best RO system, at the best price, you do not need to look any further. I did extensive research and found the Puredrop RO system to be the best overall. It has the best price, wonderful support, and is a very well-made quality system. ISPRING VS PUREDROP Puredrop is the same company that makes ISpring, which is also a very nice RO system. I was not sure if I should buy the Puredrop RO system compared the ISpring RO system, so I called support and asked the difference. I spoke with both Nick and Don who provided all the answers to my questions so that I could make an educated decision. ISpring RO t is more money, but you get more for your money: Larger Tank, a Clear 1st Stage tank, and a better faucet. In my case, it is just me and my wife, and I do not need a larger tank and I have a faucet from owning other RO systems and I would only be giving up the clear tank with the Puredrop System. CLEAR 1st STAGE TANK If you change your filters on time, there really is no reason to see inside the first stage. If you are forgetful, it may be a good idea to get the Ispring system with the clear first stage tank. FILTERS AND MEMBRANE I had other RO systems in the past, and the biggest issue I have found was the cost to replace the filters-especially the membrane, which can be as high as $40 for some name brands—especially if you have to have the check value built into the membrane. The Puredrop RO has the check valve as a separate component in the system, which eliminates having to buy a membrane one with a built-in check valve. PLUS, I love it that PureDrop provides an extra set of filters for the next time the filters need to be changed. After researching the filters, I found that I can buy generic filters for a lot less and if I wanted the Puredrop brand, it was not that much more. INSTALLATION AND SMALLER TANK The Puredrop RO system, which was easy to install with color coded water lines. So far everything is working fine and I really like the small compact tank, which gives me a lot more room for storage under the sink. There is no reason that I can see to have the larger tank for a family of two. CONCLUSION The Puredrop has been installed for a week when I wrote this review. I suspect that will not have any issues, but even if I do, I know that I can always call support: Nick or Don, and they will for sure take care of any issues I have for years to come.
Review: Very satisfied - We bought this during the latest prime day sale and we are happy with it. The installation went fine, though I did end up watching a couple videos along with using the manual to be sure I had things right. There were no leaks on startup despite there being at least 20 connections that could have a water leak. Most of those already come connected by the factory and you don't have to do them but they are still a possible leak source. I read a comment by a plumber that recommended putting something under the tank as the materials making up its valve are more likely to leak than others. This particular tank is smaller than most under sink systems so is better if it's tight under there. If you have a larger household you may want a bigger tank but I honestly think it's sufficient for most families and it is always refilling when water is depleted. My countertop had a hole already that was occupied by a soap dispenser, so I repurposed it for the included filtered water faucet and we fill a nice-looking dish soap dispenser that sits next to the sink now instead. Drilling the hole in the PVC pipe was much easier than I feared. Make sure it is done above the trap and the hole is the correct diameter. I purchased a digital total dissolved solids (TDS) device and the filtered water has been measuring 2 and 3 TDS, which is very good. The water tastes good to me despite there being no minerals and feels smooth in the mouth. It's nice knowing the water is pretty much as clean and pure as it possibly can be for us and our pets. The extra 3 filters included pushes out the filter buying time to 1 year. Reccomended.

### ⭐⭐⭐⭐⭐ Great taste, plenty of flow
*by S***N on September 25, 2025*

We have had it running for 3+ months with out any issues. The directions were pretty good but I did buy a garbage disposal ro waste adapter. I didn't have enough drain pipe to install the waste clamp so the adapter worked. Everything else came for a complete install for most people plumbing. I installed mine in the basement and ran the tubing up into the kitchen sink cabinet. I also installed a T so the output goes to the fridge and also the facet at the sink. It also comes with a complete set of extra filters so this will last year almost 2 years with out replacements. Water taste great and even the dogs love it.
