Fits the FS10 pro one blue water filter housing perfectly.
I was worried I had to buy an entire new housing and do a lot of manual work to replace the housing since proone is discontinued. Thankfully I found this website and they had the exact filter replacement that fits the original housing of the fs10. Swapping out the filter was seamless. Make sure to run the water for atleast 10minutes and I had to wait out for atleast 1-2 days for the water to stop tasting like a muddy sediment aftertaste. I still drank the water with the slight muddy aftertaste, but after about 2 days, the filter is most likely soaked fully and properly where the water should taste clean and crisp. Will be buying again from this website from now on.
