FACHIOO2PCS 7" Ceramic Filter, Replacement Filters Candle Activated Carbon for ProOne® Countertop Gravity Water Filter System, Household Water Bucket,Water Cooler Filtration Systems

Certainly not as high quality as original ProOne USA filters but I doubled up in my Traveller + and they’ve been going strong for at least 6 months now. I have yet to get any bad taste or improper filtering from them yet which very much surprised me at this price point. Would recommend in a double filter capacity.

I had an issue with a filter and they were so responsive and worked hard to correct the situation. Don't hesitate to contact Fachioo. They are great!

I live in a region with hard water that is not drinkable. Bought these to go with the filtration system and have to say I was prettt impressed with how much stuff they filter out. Our water tastes great now and no more yucky stuff.

They seem to work

I soaked the filters before use as instructed. I made sure I didn't tighten the wing nuts too tight. But still, these 2 filters together could not drain the 4 gallon tank. They stalled out about 2/3 through. So I dumped it all and started over. The same thing happened! I picked up the tank to dump it again, and the movement caused a bunch of water to suddenly run through. These filters aren't right, and I missed my return window so I'm just throwing them away.
