F9K RO Replacement Set, NSF Certified, 1-Year, Alkaline, White

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.

Used in UK Midlands Area where normal tap water reads between 360-440ppi depending on a season these filters last me 8 months as opposed to 6 months and I'm getting the water levels down to 4-10ppi. I've been running the iSpring system for 1.5 year now and am super happy with it. I've used ZeroWater filter before, but it was too expensive to run it. Yes it cleared everything down to 0, but would last only for 48l (yes I was measuring) which we consume in 6 days just from drinking tea alone. So it costs about £13/week to run. This product is estimated for me to last for 204 weeks which costs £130 - £150 depending if you catch it with a discount. That's £0.63 per week to run this. Plus a little bit of wasted water. Investing into the iSpring system already returned my investment, not in £ yet, but in sanity of not having to refill my filter constantly. With these filters I'm making soup with clean water, washing vegetables, watering plants and it lasts me for months. I've seen the new filter that iSpring is introducing which is going to reduce PPI down to 0 in theory too. Plus it's very beneficial to get the UV filters as well, because most water in UK comes from contaminated lakes ponds and rivers. While changing the filters I've broken a part which costs £13, but the support team kindly sent me a replacement part for free from the US. Later on I found out that the part wasn't broken. I was just not experienced enough! I feel happy to have it now as a spare for many more years to come. All in all can't recommend their products enough.

Very good. Easy to install if you have instruction ( manual) from Ispring. I would also recommend to add on to this kit a RO filter from Ispring ( optional). Otherwise you have to search it separately. Thank you.

The set is for year and I can easily cook on this water with a beautiful taste of the food.

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.

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!

About three years ago we have purchased the ispring reverse osmosis system and have used it nearly daily. This system has brought our cost of drinking water down to about 0,10€/l. So we were looking forward to buy another filter set. And the customer service was excellent so far -We moved and lost some parts in the process. Ispring then sent us replacement parts for free. - The fresh water storage tank once broke, ispring sent us a new one for free - We've ordered the new filter set and some parts were missing, so ispring shipped them within a day. The only downside is that our reverse osmosis system also has an alkaline filter which has to be replaced and is not included in this set. We may have to order it directly from the US. So I still want to give ispring the 5 stars for their very good customer service.

This is a good kit because I like having a larger filter pack so that I don't have to keep buying one filter at a time. Only issue I had with this is it did not have any connectors for the alkaline and the FT15 filter in the box as expected. I contacted iSpring Support, got a response from Nick the next day, who has very promptly arranged to get these shipped to me. Would not hesitate to buy again!

The water filter arrived exactly as expected, and the quality is great. I did run into a small issue where some connectors didn’t fit my existing system, but the amazing customer service team quickly stepped in. They sent me the proper adapters free of charge, making the installation process smooth and hassle-free. Now that everything is set up, I’m absolutely loving the clean, crisp, and refreshing water! The filter works efficiently, removes impurities, and makes a noticeable difference in taste. I highly recommend this filter—not just for the great performance but also for the top-notch support that truly stands behind their product. Would definitely buy again!

Me gusta la calidad de estos cartuchos de repuesto, además que son más fáciles para cambiar en la purificadora.

خاضعة للمواصفات الامركية انصح بها لمن يبحث عن الجودة 👍

muy facil de remplazar :)

La description de l'article indique que les filtres sont compatibles RCC7P, pourtant je viens de me rendre compte que les filtres post carbone ("Stage 5") ne s'adaptent pas aux raccords à vis du RCC7P, impossible de l'utiliser!!
