Main characteristic
Ultra-long service life
The activated carbon block filter has an extremely long service life and can supply a family of three to four for three months. The chlorine removal efficiency is up to 4 gallons of water. The tested water source is tap water. Please note that the actual service life depends heavily on the quality of your supply water and the frequency of your water use. The more often you change the filter, the clearer your water will be.- Great taste and fast flow
The under-sink water filter uses high-quality coconut shell carbon, which significantly improves water taste and removes odors, chlorine, and bad taste. The tested water flow of the FK99 under-sink water filter system is 2 GPM. You can get a cup of clear tap water within 3 seconds, whenever you want!
- Excellent quality
The under-sink water filter can withstand water pressure up to 600 psi and has passed the 100,000-fold water hammer test. All plastic parts are 100% BPA-free. Unlike most flimsy water filtration systems on the market, the FK99 features high-quality brass fittings that are 100% lead-free. No cracks or leaks.
- Cost-effective and environmentally friendly
Frizzlife follows the "GREENWAY" core filter replacement concept. You simply replace the inner core filter with a wrench. The outer casing is reusable for years. Less plastic waste! If recycling is too cumbersome for you, you can also purchase the complete cartridge with filter as a replacement.
- Multiple use
The water filter system can be installed in a variety of locations, including the kitchen, office, bathroom, and RV. No drilling is required for an additional faucet, making it ideal for rental properties. With the IMC-99 ice maker connection kit (Asin#B2RBMLR07), the FK26 water filter can simultaneously supply your sink and refrigerator.
- Super easy installation
The FK99 water filter system is incredibly easy to install. Only one additional hose is required. Fewer connection points reduce the risk of leaks. Everything you need for installation is included. With the help of detailed installation instructions and a video, you can install the system yourself in 3-5 minutes.

Q: What effect does the FK99 water filter have on TDS/PPM in water?
A: TDS is not a professional method for measuring water quality. TDS stands for total dissolved solids. For example, if you add a very small amount of salt (NaCl) to the water and measure the TDS level, you will find that the result is significantly too high. The same applies if your water is rich in minerals. Here, too, the TDS level will be very high.
The FK99 doesn't remove minerals from water, only heavy metals like lead, mercury, cadmium, and over 70–80 volatile organic compounds (VOCs), and largely removes chlorine from water. This is why the TDS value isn't as low as expected.
The TDS measurement method is commonly used in reverse osmosis systems because the RO filtration system also removes minerals from the water. If an RO membrane isn't performing well, the TDS will be relatively high. And if the TDS gets significantly higher, it's time to replace the RO membrane.
Therefore, please do not use TDS to test water other than the reverse osmosis system, as the result is meaningless.
Q: How often should the FK99 filter cartridges be replaced?
A: Regarding the lifespan of the SK99 filter cartridge, we recommend changing the internal filter every 12 months. Please note that the lifespan depends on the water quality and daily usage. All flow rate information on the sticker is based on laboratory tests and the water supplied. The more often you change the filter, the better your water will be.
Q: Why can't a water filter be used for well water?
A: This filter should be used with municipally treated drinking water or water that has been properly disinfected prior to use. The water filter cartridge is made of 0.5 micron activated carbon (premium quality), which can easily become clogged with dirt or debris from the well.
Q: How do I connect the FK99 filter system to the refrigerator/ice maker?
A: If you want clean and safe water from the Frizzlife filtration system for your refrigerator or ice maker, an IMC-2 ice maker kit is also available in our online store.
