iSpring F9K 1-Year Reverse Osmosis Water Filter Replacement Cartridge Pack Set for 6-Stage Alkaline Mineral RO Filtration Systems, Without Membrane, White

Ordered replacement filters - experience of changing them was good. Using this filter systems from last 4+ years now. Good water taste and healthy for kids so far. Saves lot of plastic bottles and efforts to bring/recycle them.

Very fast delivery and easy to install. You need to run the cycles about 3 times before drinking the water again.

We've had our RO system for years and it's always easy to order the replacement filters. We've never had any issues!

The item arrived on time, and the packaging was good. My previous one stopped working after 7 months, and I was shocked to find the filter covered in rust and debris, which proves it's doing its job. Definitely recommend!

High quality. Great tasting water. Good support from Customer Service when necessary

Buy it, install it and get done with ever buying cases of bottled water!!

The delivery was on prompt. Product quality was good at reasonable price

Perfect fitment, super easy to install, love iSpring!

Not the best price, some after market are just as good for less cost. If you have a TDS meter, you will not get zero TDS, so zero water is better filter when it comes to lower number of TDS. I think i-spring filters' quality has gotten worse over the years. My first RO made by i-spring, I used to get zero TDS but not anymore.

had the system for a year, filter replacement video is inaccurate, replacing filters is too much trouble with connectors breaking in half and leaks common. i bought another system.
