Review: Excellent product, fantastic customer service! - If anyone is considering buying a good water filter, look no further! The iSpring 7-Stage 75 GPD UV Ultra Violet Alkaline Mineral Reverse Osmosis Water System is what you want. If you think you might need help, do not worry! The customer service is excellent! They will make you feel nice and comfortable when you contact them. I am not sure if I can find the right words to express how fantastic experience I have had with iSpring exceptional customer service! But let's start from the beginning (not from Adam and Eve though, do not worry! LOL). Why I have bought a water filter. Most people do not know that the mineral water sold in plastic bottles is not healthy at all. There are 7 types of plastics and plastic containers are marked with a triangle of three "chasing arrows", which encloses a number giving the plastic type. The plastics which are typically used to hold water but also soft drinks, juice, sports drinks, beer, mouthwash, ketchup, and salad dressing are made from a plastic marked as number 1. That indicates that those containers are made of Polyethylene Terephthalate (PET). Although that plastic is considered to be safe, it contains antimony, a metalloid element with toxic qualities, which leaches from PET. The rate of leakage increases with temperature and can yield unhealthy levels in bottles stored in higher temperature. Antimony can cause acute and chronic health issues, such as diarrhoea, vomiting, and stomach ulcers. Brominated compounds can also leach into PET bottles. They can irritate the skin, mucous membranes, and tissues. If you bear in mind that even though the levels of toxins leached from PET could be considered as on a safe level, they may accumulate in your system over a period of time becoming a serious health risk. That is why I decided to install a multilevel water filtration system at my home. Why I have bought iSpring 7-Stage 75 GPD UV Ultra Violet Alkaline Mineral Reverse Osmosis Water System. The iSpring 7-Stage 75 GPD UV Ultra Violet Alkaline Mineral Reverse Osmosis Water System seemed to be the best offer on the market. It cleans your water from everything you need for a good price. I was not sure if I should order the system with or without the booster pump. I live in a big city and I thought the city water pressure should be strong enough to work with the system so I decided to go for the one without the booster pump. My buying experience. The order arrived quickly and before I even started installing the system, I received an e-mail from iSpring to thank for the purchase and to say that if the Feed Water Adapter (AFW) that taps into the cold water line did not fit my plumbing specifications, they would fully refund (shipping included) for the order of the AFWs that I needed. They included two links to AFWs which I could choose from. Once I ordered the AFW, I e-mailed iSpring customer service and almost instantly I was issued the full refund for my order! My installation experience. The installation of the system was easy. The package contained a very easy instruction with colour photos leading you through all the steps of the process. If you do everything as the instruction manual says, you will be fine. I did not have any problem at all, no leakage whatsoever. My surprise. Everything was fine but I noticed that my water tank stored only 2-2.5 litres of water. I wanted to use filtered water not only for drinking and cooking but also for washing fruits and vegetables and that volume of water was not acceptable for me. My contact with the customers service. I e-mailed customer service and they replied very quickly giving me a short check list. It was very easy to follow the instruction and give the system a check. The whole process took a couple of minutes. Further instructions made us come to a conclusion that my water pressure was below 45 psi and that was a problem. I needed a system with a booster pump. I was too optimistic thinking that my city water should be fine and I did not need the booster pump. Once we identified the problem, the iSpring customer service came with a solution. To make it easier for me and avoid possibly a bit complicated installation of the booster pump and its components on my existing system, they offered ordering a machine head with a booster pump factory installed. And here comes the best! As they understood that the water storage was of great inconvenience to me, they reduced the price of the machine head from 90 to 50 dollars! Since it had to be shipped from iSpring office in the United States, not the shop in the United Kingdom, where I live, that would generate some extra costs of shipping and the import tax. iSpring customer service offered me splitting the costs of shipping and the import tax! Solving the problem. My problem was solved. After installation the machine head with booster pump, the tank stores about 10 litres of water and that is what I need! I can hardly hear the pump working. The water pressure is very good and the tank fills up very quickly. The water tastes fantastic, much better than bottled water, no plastic aftertaste. My final thoughts. What else would you want from a customer service?! They could not do anything more or better! They are exceptionally kind, understanding, efficient, and professional! I highly recommend iSpring water to everybody. They are like a good friend, who is always around when you need them. I was very lucky having chosen iSpring and their product.
Review: Great product - Easy to install, water tastes great, tds in my tap water is around 310pp after filtration it ranges around 25-30pp. Nothing to complain. Water tank gives around 10 liter of water at your disposal.

## Questions & Answers

**Q: Is the tank metal, plus are there alternative taps as we have a granite worktop so would be good to use existing whole and use a 3 way tap.**
A: The tank is metal and we've installed the whole set up outside in a protected space. I sold the provided tap on eBay and  connected the filter to our hot tap, so I don't imagine you should have any issue connecting to your 3way tap.

**Q: Good morning, I want to know how many liters of water can be filtered with a set of filters ?**
A: Hi, 
ISpring recommends changing filters once every 6 months. I did not like the idea of changing filters that are still Ok. Several things to take into consideration:
1. the (lack of) quality of the water to filter.
2. if you have any filtering installation before the iSpring.
3. the regular maintenance of the iSpring.

In my particular case, here is what I did:
1. water quality to filter is poor. Water is hard and there is mud from time to time due to old pipes breaking in the village.
2. I have several filters before the iSpring. One 50 microns, one 10 microns and then a resin system to remove calcium and magnesium from the water ( classical one with salt to regenerate the resin). They remove a lot of cheap already. Then finally comes the iSpring. 
3. Regarding the maintenance of Osmosis systems, it is recommended to flush the membrane on a regular basis. I do it once a month. You need to add one valve in the circuit for that, not included in the iSpring setup. Check YouTube.

I did some more additions. I placed manometers: One before the first filter of the iSpring and one after the third one. As the three first filters will fill-up with dirt, there will be more pressure drop while water flows through. 
I also do visual control of first filter, the transparent one. Changes color? Time to replace.
More important I invested in a double meter that measures ppm before and after the reverse Osmosis membrane. In my case 127 ppm before. When pre-filters lose efficiency this number goes up. And after the membrane it should stay close to 0. If it does not, time to change membrane and all pre-filters and probably post processing cartridge that adds minerals.
I also added a water counter right before the iSpring in the conditions above, I passed 7 cubic meters without issues in one year, no filter change needed so far.
The UV light, you can see if it works in the dark.
Last addition, I have put a T on the pipe that goes to the tank, a valve and a special cartridge to remove the last particles that still may be in the water. This cartridge is black when OK and yellow when content needs replacement. They describe it as an option in iSpring system but I did not find it on sale. So I bought one from another brand on Amazon. I use the valve and cartridge to produce "distilled" or rather demineralized water for clothes ironing.
Last thing, the tap provided does not look so good on the kitchen... and you need to punch an additional hole in the sink. But Amazon sells kitchen tap with two control knobs. One for normal warm/cold water and one for filtered water in the same tap. In chrome, looking good.
This system is the best investment I have done in years. It changed our life. No more bottles and all the plastic waste. The water tastes real good. You drink as much as you want. If interested in the additions I made to the system, check YouTube.

**Q: Hi. I just bought the 7 step osmosis filter. When the external pressure tank is full, does the incoming water stop going through the system?**
A: Hi there,

Thank you for contacting iSpring Water Systems. Yes, once the tank is full, your auto shut off valve will turn off the supply and will start when pressure is released when you turn on your RO faucet.

For immediate assistance, please call us or visit our website and click the "Support" link on top to create a support ticket. We will respond within 24 business hours.

We look forward to talking to you.

Kind Regards,

iSpring Water Systems

**Q: Can this pack be used for ispring rcc7ak 6-stage? (even if lamp is not needed) - still can it be used for 6 stage one? seems that it can. cheers**
A: Hi,

Thank you for asking this question. Yes you can. That's the same type of filters or search for iSpring F9K. That's specifically for the RCC7AK.

Kind Regards,

### ⭐⭐⭐⭐⭐ Great product
*by U***A on 24 September 2025*

Easy to install, water tastes great, tds in my tap water is around 310pp after filtration it ranges around 25-30pp. Nothing to complain. Water tank gives around 10 liter of water at your disposal.

### ⭐⭐⭐⭐⭐ Great customer support
*by A***M on 21 April 2025*

I bought the RO filter as we live in London and got tired of hard water distorting coffee/tea taste, causing constant descaling, etc. The filter was super easy to assemble, all connections were super well done and step by step YouTube installation video was super easy to follow. I have noticed that one of the factory connects was dripping, tried reconnecting it in different ways and contacted iSpring support in the end. They came back with a response in less than a day and shipped me a replacement for the faulty part. I was pleasantly surprised with the speed of reply and the help I received. I talked with Julius and I cannot thank him enough for such high quality service, especially today, when most companies just send you to AI bots, which often appear to be useless. Well done to iSpring, this is great customer support! I highly recommend buying their products!
