F19K75

Pretty solid replacement set if you’re running an iSpring RO system. The gives you everything you need for about two years, which makes maintenance way easier instead of buying filters one by one. I like that it’s NSF certified and actually improves the taste of the water—noticeably cleaner and smoother. Installation is pretty straightforward if you’ve done filters before. It’s not the cheapest upfront, but considering it covers multiple replacements and includes the RO membrane, it’s a good value overall.

I’ve been using iSpring reverse osmosis systems for years, and this 2-year replacement filter set is a total game-changer. The F19K75 set has everything I need to keep my 6-stage RO system running like new, and the fact that it’s NSF certified gives me extra peace of mind about water safety. Installation was straightforward—even for someone like me who's not exactly a plumber. All the filters are clearly labeled and well-packaged. I especially love the alkaline mineral filter—it really improves the taste of the water and helps balance the pH. It’s crisp, clean, and noticeably better than bottled water. The 19-count set is a great value and lasts the full 2 years as advertised, so I’m not constantly reordering or worrying about when to change them. It’s a small investment for long-lasting, high-quality water right from my tap. Highly recommended for anyone with an iSpring system. You can really taste the difference!

Nick did a great job helping me with the changing of the filters and trouble shooting my installation!

Works great , on out small town water

Love the product but got a broken filter in this collection

I’ve been using iSpring filters for a few years now, and this F19K75 2-Year Replacement Pack is by far one of the most convenient and reliable options out there. The installation was straightforward — everything fit perfectly into my iSpring RO system without any leaks or hassle. If you’re maintaining a 5-stage or 6-stage iSpring system, this pack is a no-brainer. Great value, easy installation, and excellent water quality. Highly recommend!

I was having problems with my Home Depot Reverse Osmosis water filter made by GE. I decided it was time to upgrade to a better system. The GE system had two charcol filters and an RO filter. The cost for all three filters was over $100 and the cheap charcoal filters they are using now clogged the RO filter in 6 months. The iSpring system has a sediment filter inside a clear see through holder so you can see a problem before it ruins the RO filter. The filters on the iSpring F19K75 2-Year Replacement Supply Set was $122 dollars for a set of 12 filters and a RO filter. You're getting a 2 year 6 stage setup for $60 dollars a year! And you're getting a company located in Atlanta that is quick to respond to any problems you might have. My wife and I are really pleased with this system. It provides excellent tasting water that I am comfortable providing to my family. The Alkaline Remineralization Filter makes a big difference in the taste and the minerals it puts back in are good for your health. I have added the optional hookup to my ice maker and now I am getting crystal clear ice cubes. It really improves the taste of coffee and tea. I quit drinking and using tap water for cooking 20 years ago because I know what is in it. Every farmer from here to Canada is applying insecticides and pesticides that eventually reach the rivers and waters we drink from. These iSpring filters have reduced my total dissolved solids from over two hundred to less than 30 and most of the 30 is the good minerals I am putting back into the water. Read all the documentation and articles that iSpring provides on Amazon and you will be convinced you are dealing with a company that cares about providing chemical free drinking water to your family.

Love the iSpring products . Exceptional quality and great customer support . Nick is the best!

Muy bien pero me salió un filtro alcalino defectuoso. Me podrían mandar el repuesto del filtro alcalino defectuoso? Esta tapado!

2018年から使い出したRCC7P用にストックします。 ミネラルカートリッジも付いているので、配管含めて追加してみます。 入口が80～120ppmの水なのでフィルターの持ちが良い気がして、１～２年の交換周期を伸ばして使っています。基本的に浄水水量が確保されていれば、頻繁に交換する必要はないと考えている。

great filters for fantastic system, very happy :)

3年前と比べて30％もお安くなってます(￣0￣)☆-1。未使用のフィルターをストックしておくスペースはそれなりに必要です。交換サイクルは各戸の使用状況でかなり違うのではないでしょうか。今回のフィルター交換で一番の気付きは 圧力タンクの中も洗浄した方が良いということ。自転車の空気入れを使って全排出を数回試みました(笑)。

I’ve been using this water filter system for about two years, and it produces excellent water quality. I’ll never go back to using fridge filters again! The only issue I had was a minor leak once, but when I called iSpring, Sean patiently guided me through the troubleshooting process. Now it works perfectly. I’d definitely recommend this product to others!
