Review: Best domestic water filter backed by truly *Excellent* Customer service - 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 desertcart 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 desertcart) 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. Review: Superb Product and Support. - 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. ## Features - Individually wrapped 1-year high capacity filter replacement cartridge pack for 6-stage RO systems - Experience clean, safe, and good-tasting water every time you turn on the faucet. Enjoy crystal clear ice cubes, fresher tea and coffee, better tasting foods, healthier baby formula – even better than most bottled water - The RO membrane removes not only harmful pollutants but also a few helpful minerals. As a result, a standard 5 stage RO system produces slightly acidic water with a pH of 7. 0 or below. Alkaline mineral filter produces alkaline water with restored healthy minerals such as natural calcium, magnesium, and potassium ions, which ph-balances the RO water. - 9 pieces of 10" x 2. 5" replacement water filters included: 2x sediment filters, 2x granular activated carbon filters, 2x carbon block filters, 1x post-carbon filter, and 2x alkaline filters - This filter pack does NOT include an RO membrane. Updated FA15 alkaline mineral filters and FT15 post-carbon filters are built with a secure push-fit quick connection, which allows faster filter replacement. If you have trouble installing the filters, please refer to the user manual or contact us ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00BOASJ1M | | Benefits | Removes harmful contaminants, restores natural alkalinity and mineral balance, and provides great-tasting mineral water. | | Best Sellers Rank | 25,258 in DIY & Tools ( See Top 100 in DIY & Tools ) 18 in Replacement Under-Sink Water Filters | | Brand Name | iSpring | | Compatible Water Purifier Models | iSpring RCC7AK | | Country Of Origin | China | | Customer Reviews | 4.6 4.6 out of 5 stars (5,779) | | EU Spare Part Availability Duration | 1 Years | | External Testing Certification | ANSI | | Global Trade Identification Number | 00662425058518 | | Included Components | 2x sediment filters, 2x granular activated carbon filters, 2x carbon block filters, 1x post-carbon filter, 2x alkaline filters | | Item Dimensions D x W x H | 6D x 11W x 22H centimetres | | Item Type Name | 1 Year Set with AK filter | | Item Weight | 2.7 Kilograms | | Manufacturer | iSpring | | Manufacturer Part Number | F9K | | Material Type | carbon | | Model Number | F9K | | Number of Items | 1 | | Set Name | 1-Year Filter Pack | | UPC | 662425058518 | | Unit Count | 1.0 count | ## Product Details - **External testing certification:** ANSI - **Item weight:** 2.7 Kilograms - **Material:** carbon - **Product dimensions:** 6D x 11W x 22H centimetres ## Images ![F9K 1-Year Reverse Osmosis Water Filter Replacement Cartridge Pack Set for 6-Stage Alkaline Mineral RO Filtration Systems, Without Membrane, White - Image 1](https://m.media-amazon.com/images/I/710Va9Yu4hL.jpg) ## Available Options This product comes in different **Model** options. ## Questions & Answers **Q: Can I buy the membrane separately? I’ve bought this one, didn’t realise. The membrane will need replacing in 5months** A: Yes. The membranes are standard sizes. **Q: Hi i have a 6 stage reverse osmosis from Geekpure water are your replacements compatible with this brand?** A: Not sure, better to ask manufacturers/suppliers **Q: Is this the correct filter kit for rcc7ak?** A: Yes but ... That kit is two changes of the filters that should be changed every 6 to 12 months and one change for the filter that needs to be changed every 12 to 24 months. That's the "Yes" part. Its five of the six filters in the water filter. The "But" is that there is another filter that needs to be changed every 3 to 6 years. That's the reverse osmosis membrane itself. That is not included. If your water filter is due a membrane change, you need that membrane filter too. **Q: Does this filter pack include the membrane filter?** A: No it doesn't. Membrane filter needs to be changed every 2 years so it has to be bought separately. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Best domestic water filter backed by truly *Excellent* Customer service *by T***. on 24 May 2021* I've had an iSpring RCC7AK 6-stage filter system since November 2017.

I would also recommend to add on to this kit a RO filter from Ispring ( optional). Otherwise you have to search it separately.
