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: Best water I’ve tasted and will pay for itself in a few short months - Easy to install not a problem with leakage at all , I personally drained my storage tanks twice then connected my uv up and drained a third time water tastes great like rain water only way I can explain it , the design makes it pretty self explanatory and is a good quality product I’d recommend it especially if your on well water and share a well that doesn’t get much attention . Thank You !

### ⭐⭐⭐⭐⭐ Solid product
*by N***E on October 13, 2025*

I honestly wish I had something bad to say about this system. But I got it at a really good price (127$) and it’s working flawlessly. It was pretty easy to set up. The instructions were a little confusing. But overall very easy set up and it works pretty good. I also like that it comes with replacement filters. Got my water down to about 20 ppm but don’t quote me on that because I can’t guarantee the accuracy of my meters ha ha. It fits under the sink nicely. I don’t use it for drinking water, but I do use it for my humidifier and I haven’t seen any residue buildup in the room since I’ve switched to RO.
