iSpring F28K75 RO Replacement Set, NSF Certified, 3-Year, 28-Pc, Alkaline

I've had an iSpring RCC7AK 6-stage filter system since November 2017. It was fitted by my local Kitchen & Bathroom company, alongside a new sink/tap and a Harvey whole-house water filter. It has provided brilliantly clear and tasty drinking water since installation, at an annual price of around what we used to pay for bottled tap water. At the time, I also bought a water quality hardness test meter - which showed a TDS (total dissolved solids) value of around 30, compared with tap water's 300. I'm so used to our lovely filtered water that a recent stay at a friend's house gave me a nasty shock when I drank her unfiltered tap water - I could both smell and taste the chlorine! Yuk. Anyway, I'm now starting my second set of replacement filters - best bought as a 3 year supply when the Amazon price is lowest - and found that one of the cartridge filters had a small leak from a screw-in connector; unscrewing it and remaking the joint with PTFE tape just didn't fix it, so I asked for help from iSpring Europe. A very nice man named Don asked me to register my problem on their American website (where I could attach an image of my replacement filter order from Amazon) and then he helped me by sending a set of replacement fixtures, plus some spare connecting pipe. A big bag of connectors (more than I needed, really) came all the way from the USA by Fedex in 4 days and has *completely* fixed the problem. I fitted it in minutes, along with some of the replacement pipe (because I predicted that the angle of the exit pipe in relation to the next filter in the set would probably be different - and it was). No leak, no worries. Wonderful. Now, in case anyone is thinking "well it shouldn't leak in the first place" my response is that this connector has been made/remade several times and is the only part that has ever had a problem. Every other joint has been 100% water-tight. More importantly, I understand the the latest versions of the cartridge-type filters already have this fitting built into the filter - so when I buy my next replacement filter set, all I will have to do is to push-fit in the connecting tube, making changing them very simple indeed! So, if you are looking for a multi-part (and therefore professionally engineered) drinking water filter system, look no further than iSpring. In my view, they sell the best comprehensive water filter which is compact, efficient and delivers a very cost-effective way to drink purified water - with absolutely no plastic bottle waste! On top of that, their customer service is *amazing*. You simply can't do better.

I've decided to buy 3 year pack of filters as they are good value for money. When I received the parcel I was really concerned about 5th and 6th stage filters as the fitting is different than in my system, and about the RO as it is packed in dry non vacuum sealed packing with no GPD label. I have contacted the iSpring support and they responded very quickly with helpful information. Even though my iSpring filter system is only 4 months old, the 5th and 6th stage filters were upgraded with quick fitting and iSpring offered to send me free of charge proper adapters so I will be able seamlessly use new type filters in my system. The RO is packed in dry packing for longer storage and have correct 75GPD rating. I like my iSpring filter system and I'm really pleased with vendor's support, I can't really say much about the filters apart from them being genuine product. I'm going to replace filters in 2 months so in case of anything worthy of saying, I'll update the review.

Very happy with the filter set. Does the job very well. You only realise how good they are when you drink water away from home. Not cheap, but well worth the money. Good seller. +++++

Was missing connection part, contacted customer care, excellent service, issue sorted by Nick. Good value for money and excellent customer service

Good quality. Recommend

I bought this water filter about 18 months ago and we are very happy with it. Installing the filter was a bit of a faff and pretty time consuming, but the instructions are not bad at all - just takes 2-3 hours. Once installed it has worked perfectly - we have quite chlorinated water and the filter completely deals with that. The taste is very fresh and the last filter which puts minerals back into the filtered water gives it a pleasant taste. We also bought a large box containing all the filters that we will need for 2-3 years. Changing the filters (some twice a year, some once a year) is fairly easy and takes 5-10 minutes depending how many you are changing. Change done, you hang the filter back on its hooks, close the cupboard door and forget about it for another 6 months!

Fast Shipping and excellent products.

Product arrived promptly but with little instruction however when referring to u tube the dis assembly and assembly instructions were amply illustrated

muy facil de remplazar :)

Muy buenos y buen precio en oferta.

Sehr Gute Osmose Filter

I recently purchased the iSpring RCC7AK 6-Stage Reverse Osmosis System and it arrived exactly on schedule. They have a great customer service I contacted customer service and spoke with Nick, who was incredibly professional. He walked me through the installation steps. Now that the system is up and running, I couldn't be happier. The water tastes fantastic, and my whole family loves it. I was so impressed with this RO filter that I’ve already ordered the 3-year filter replacement supply, which is very reasonably priced. I already told my friends about this RO filter system I highly recommend this system to them and anyone else who is looking to purchase a new RO system! Thank you iSring team for the great RO water filter and wonderful customer service.

Great tasting water! I have been very happy with this filter. Nick from customer service has been very helpful!
