iSpring RO5004F Reverse Osmosis Water Filter with UV, 500 GPD RO System Under Sink, 2:1 Pure to Drain, Tankless RO Water Filtration System with Boost Pump, Filter Life Monitor, Reduces PFAS, TDS, Lead, Arsenic

Couldn��t be happier with my decision to install our water softener and reverse osmosis filter. The difference it has made in our water quality is incredible improving so many aspects of our life. Having pure clean water on top is such a luxury and we feel good knowing we are not reliant on moldy brita pitchers or endless water bottles. Our dishes and ice are better and we even noticed a difference in our skin and hair. Also 5 stars to Sean the service rep who helped me track down a sediment filter when they were in short supply. He personally made sure one was sent to me straight from the warehouse and he couldn��t have been more professional and courteous.

The installation for this product was fairly simple. It is pretty bulky so make sure you have enough space in your cabinet. The flow of the water has a slight delay like two seconds which I assume is how long it takes for the water to be filtered through the system. It��s slow but I think it��s the perfect amount to grab water for my water bottle and kitchen needs. Overall I really like this product as my town has frequent water boil notices and this will help my household have a piece of mind.

Ispring RO 500 ..I��ve been using this winter filtration for many years and I fall in with it. The problem I encounter is replacing the filters. Sometimes I didn��t do it right I either flush the system too long or pressed the wrong button and it caused malfunction: the blinking light come on.Anyway I'm still stuck with ISPRING because the customer service is super good they are very helpful whenever I needed them.Shawn is great. He went above and beyond whenever I needed his help regardless how long I have the system.I was impressed by Shawn��s willingness to help and provide solutions. he is exceptional!!!I recommend this unit to anyone who is contemplating to buy one do not hesitate.. the customer is super great they are always there to help.

Life changer! So grateful I got the chance to try this. Not only does the water taste great but it has also saved me so much money because I don��t have to buy water at the store anymore. The installation was simple and the steps were very clear. I like that it��s slim and doesn��t take up much space under the kitchen sink. The water quality has been great! Such an amazing water filter!!! 10/10

I've been really impressed with the RO5004F system. The tankless design freed up so much space under my sink and the water flow is surprisingly fast - no long waiting like traditional RO systems. The built-in pump keeps the pressure strong and runs fairly quietly.I love that it includes UV protection for an extra layer of safety and the filter life monitor makes maintenance simple. The water tastes crisp and clean and knowing it reduces PFAS lead and arsenic gives me peace of mind. Installation does require some DIY efforts but overall it's a high-performance reliable system that's worth it.

The spring R05994F is an amazing amazing osmosis water filtering machine with the technical quality superior to any other company I��ve come across and it is so quiet and the flow rate is ideal for a home or a Business and the water quality and taste is better than anything I��ve every used and it seems the durability will outlast my time in this home as for the maintenance it seems to be as easy as the install and super quick to change out the filters

I have been very impressed with the performance of this system. The water taste extremely clean and fresh and the UV features adds extra peace of mind. Installation was straight forward with clear instructions and the tankless design saves a lot of space under the sink the filter feels well build and durable and the system runs quietly with consistent water flow. Cost efficient and free of any leaks. The value of this product is amazing.

I am highly critical of water filtration claims but the iSpring RO5004D is a legitimately impressive system. Traditional RO systems use a storage tank which can unfortunately become a breeding ground for secondary bacterial contamination over time. The tankless design of this unit completely eliminates that risk and the addition of the final stage UV filter ensures any lingering bacteria are neutralized. Living in an area with heavily treated municipal water the difference in taste is night and day. Beyond the purity the 2:1 pure to drain ratio is incredibly efficient for an RO system. The 500 GPD flow rate is fast enough that you don��t miss the reservoir tank at all. If you want true lab grade clean water at home without sacrificing all your cabinet space this is the system for install.

Thank you I-Spring for making clean drinking water affordable and available. Lets face it, frig filters aren't enough against PFAS, TDS, lead and arsenic! The RO system was an easy self install. The water is crystal clear and tastes great. The warranty process was easy too. Sean was really helpful with obtaining my extended 3-year warranty once I sent him a copy of my receipt via email and after I registered my product with I-Spring website. Thanks, Sean!

I have nothing but very positive things to say about this RO filter and the iSpring company itself. Online only a few weeks it has performed flawlessly and water quality has been outstanding. My interaction with customer service has been a very bright spot. I have had the pleasure of working with Sean three times with questions about setup and adjustments/addition needed to system use with refrigerator ice maker/water dispenser. Sean's customer service skills and product knowledge was beyond reproach. He followed up on two occasions to make sure everything worked fine and I was happy with my system. Thank you!

My 5 star review is for the customer service that Nick gave me over the phone. In this day and age customer service usually is nonexistent. Nick thank you for getting right on my issue and sending out a new unit my original unit had a constant drain issue never shut off. I have several different Ispring filters in my system and have been very happy with those. Good to see a company care about their customers! Thanks Erick T

I researched this product and suggested this to my sister a a replacement for an older under sink RO system at our mothers house. Her plummer installed it. The system kept turning on/off with the green UV filter LED glowing every 15 seconds. Sis was going to return through Amazon. I looked at system and called ispring customer service. Sean was extremely helpful.........He picked up on the second ring and I was talking with a live tech support person in the United States....wow! I sent Sean a video of the issue and we determined that the reason for the system cycling like this was that this is a tankless system (the older system had a tank) and it's hooked up to an ice maker. The ice maker need a tank for the water supply. Once I turned off the valve to the ice maker the constant cycling stopped. Sean is sending a tank and we will install. GREAT customer service. Thanks Sean! This is a nice system. I would recommend this.

This system is unbelievable. An absolute game changer. I live in a city with pretty awful water and I am very sensitive to it. This has made my life so much easier and less stressful. The fact that it comes with the little faucet is such an awesome touch. Ill never stop raving about this system
