- RO500AK-BN Reverse Osmosis Water Filter, NSF 58 Certified, 500 GPD Tankless Under Sink RO System, Natural pH Alkaline Remineralization, 2:1 Pure to Drain Ratio, Brushed Nickel Faucet

This iSpring RO600 is excellent! I purchased this iSpring to replace a 5-stage RO system with a tank (a different popular brand), as I had bought replacement membranes for that system, but they produced a weird and horrible taste. When I contacted that former RO's customer service, they were difficult to get a hold of, then rude on the phone when I finally got through, then asked to send in pictures of the faulty system and filters via email. They ended up not helping us and were rude in the non-ownership of the problem their replacement filters had created. That lead me to research a lot of systems here on Amazon and decided to purchase this iSpring system because of all the wonderful features. The RO600 takes up less than half of the valuable under-sink space that the former 5-stage did; it is sleek-looking; and the water waste for purification is less than half of that of the 5- stage, which translates into more money in my pocket at the end of the month. I will never go back to a tank! The RO600 is very quiet and the water the iSpring puts out is clean, clear, refreshing, and tasteless. The RO600 puts out water much more quickly than my old system. Also, there is no guessing if everything is okay with the iSpring, or if a filter needs to be replaced, because of the 3 LED lights on it. It is also an easy process to change the 2 membranes, unlike traditional RO systems. So you don't end up with water all over the floor and old filters in your sink draining for hours after changing the 5 different membranes. The iSpring is plug-and-play and you don't need a special wrench for the task! The filters are very affordable when replacement time rolls around, especially since one of the two membranes only needs to be replaced every 2 years, and the second one, once a year. This saves a lot of money compared to 5 + membranes replaced each year with other systems. It comes out to less than $1.50 per week for a 600 gpd RO system. If you have any questions regarding the system, the customer service is outstanding. There's someone who can answer your questions that's based here in the U.S., and you feel like a valued customer. This is a night-and-day difference from my other experience, and I will be an iSpring customer for life! Finally, there were some reviews stating that it couldn't be hooked up to a fridge. Ours is spliced out to our 2012 Maytag and it works just fine. It has a tiny delay the first 1/4 second of operation, but runs smoothly after that. (I believe it's just the length of the connecting line, combined with gravity.) This does not bother me and I really wouldn't think anything of it, other than trying to be 100% honest in a review. I'm glad I chose the iSpring RO600 for my home. It was a great financial and healthy investment for clean drinking water for my family of four and a total upgrade from my old 5-stage RO system with a tank.

This ISpring Tankless RO is exceptional both in function and in the amazing service that is provided for ongoing support. Drinking water is THE major health issue for overall wellness, longevity, etc. First the product...it is tankless so installation under a sink is straightforward. I still had my plumber do it and he was done in 10 minutes. Then you get crystal clear on demand drinking water all day. Suddenly my coffee, tea, soups, etc. all taste amazing. Filter changes are a breeze...on a six month, one year, and two year cycle....it is just a quarter turn and done. It is easier than changing inkjet printer cartridges. Next, the service. ISpring provides support with REAL HUMANS. You call on an issue of filter change or anything else and a helpful rep with real expertise is there to guide you. In my case my system started to act up and not deliver water without unplugging and replugging the unit several times. I called ISpring and my rep -- NICK -- listened to the pattern I described and determined it was an issue with the pump....my unit was 21 months old and within the warranty and he promptly sent me a new base unit! This was amazing....they really do stand behind their product and the price is so reasonable for something that is essential every day. I tell everyone about this system because of its quality and for super service reps like NICK who truly care about their clients.!

It has been a few weeks since I installed the iSpring and it has worked flawlessly. The installation instructions, both written and video, were very easy to follow and the installation went off without a hitch. I'd have to say that the most difficult thing was registering the product online. LOL. The registration liaison, Sean, was very helpful and quick to respond. I've had the tank RO systems in the past and the tankless is a great improvement for us and the amount of clear, clean water that we go through on a daily basis. The only thing I had reservations about was the speed of water flow but it is completely adequate for all our needs. Everything, especially the coffee and tea, tastes better. Overall a great experience. I am hoping to have many, many filter changes in the years to come.

Using this along with the 6 stage Ispring reverse osmosis system I finally have safe drinking water (checked after a lab test from the hospital). I did have issues with my initial light, it made a loud buzzing noise and the light wouldn't stay on. I contacted Ispring support and Nick was quick to help(a day or two to respond through help tickets)and sent out a new one quickly. It still makes a slight noise but seems to be working fine.

YouTubeの動画を観ると説明書を見なくても取り付けできます。取水の分岐もアダプター無しでそのまま取り付けできました。音も静かで水量も充分です。

فلتر ممتاز ولكن يجب تزويد المنتج بأرقام الفلاتر ليتم استبدالها

Bought the Ispring RO 500 but came with missing parts. Not sure if this is an Amazon issue but regardless. Nick at Isping took care of the problem promptly and sent the missing items quickly. Ispring costumer support is exemplary and would not hesitate to buy more items here if I needed.

Muy elegante y compacto
