Frizzlife FZ-2 Replacement Filter Cartridge For MP99, MK99, MS99 Under Sink Water Filter & MV99 RV Filter

I changed one of these out after a year, and you couldn't even tell it had been used, I use it on my LG refrigerator, I'm not even going to mess with it until 3 years have passed, the water is clear, it doesn't have a chlorine taste, and it was fairly easy to install under my sink, I was having a problem with the built-in filter on the refrigerator leaking, after talking to a technician, he suggested that the water pressure was too low, I knew that wasn't the case because I tested the pressure going out of the filter, and it showed 70 pounds, so I removed the built-in refrigerator filter, and installed this filter, and have had no problems since. BTW, this filter will save a lot of money in the long run, those refrigerator filters are expensive, and they need to be changed every 6 months, I highly recommend these filters.

Water filter cartridges from the manufacturer of the filter system. Originally purchased the filter system on Amazon. Everything continues to work very well. These are replacement cartridges. Fit perfectly and are easy to change. Recommend both the Fizzlife filter and replacement cartridges

I use these filters both on my RV and for my under-counter system. I have always had great results using Frizzlife filters.

I purchased this filter several months ago and initial installation was fairly easy. I did it myself. I liked that it was under the faucet and therefore didn’t need to be stored in the fridge. Water quality tasted better, so figured it worked well. I just installed the replacement filter, which was also fairly easy (though it didn’t come with instructions). I also purchased a water tester to compare the tap water vs. filtered water. I tested the old filter level, which came out to 160 ppm. The bathroom water was at 149 ppm, so it was almost worse to have the dirty filter in! After replacing the filter, I let it run for 5-10 minutes and level went as low as 110ppm, which I figured it would continue to go down with use. After several uses (maybe 15-20 times), I took another reading... 149ppm! I am disappointed. Ideal drinking water is below 50ppm, however the level that it is at now is well within the safe range to drink. Because it does taste better, it is probably doing what it claims by removing the chlorine, and any possible metals. After looking at the item description, it does claim to leave behind the trace minerals, that are good for you which explains the relatively high ppm.

Been using these for years, never disappointed. Good water good price and excellent customer service.

We have had the undersink filter system over 5 years and re-ordered cartridge replacements as suggested. All of our cold water is filtered, at least we feel confident if anyone should happen to drink straight from the tap - it will taste great and be as clear of harmful content as much as possible.

We use this filter in the Frizzlife water filter system for our cold-water source, making it perfect for brewing coffee, cooking, and providing drinking water for us and our cat. These filters work great and make a noticeable difference in the taste of our water.

Like using these filters for my rv. Easy to get, easy to change out and good life span. We (family of 4) full time rv and it last about 4-6 month with no pressure loss. Filters pretty good I feel. Price is good also, we all would like things cheaper of course.

I've been using the Frizzlife MK99 system for a while now, and this replacement cartridge continues to impress. Installation was quick and tool-free—just a simple twist to remove and insert the new filter. The used filter (as seen in the photo) clearly did its job, catching visible contaminants, while the water output remains crisp and clean-tasting. I appreciate the dual-stage filtration—one for sediment and one for finer contaminants. It fits perfectly and seals well with the double O-rings, so there are no leaks at all. The build quality is solid, and the filter lasts for several months with consistent performance. Highly recommended for anyone using the MK99 system. Clean water, easy maintenance, and peace of mind!
