Review: No fluoride for me - These are great filters. Extracts all the bad stuff. I live in the city with really processed water and these filters do the job well, leaving me with crisp clean tasteless water. You can smell how much it is actually filtering when you open the top lid. A little on the expensive side but we'll worth the money if you want to drink pristine water.
Review: Works great - I have had this filter for over a month and love it..i have it installed in a 3.5 gal bucket dripping into a 5 gal bucket..it takes about 5 hours to filter 3 gals of water but the amount would be faster if you keep the entire filter covered in water. It slows down drastically after entire filter isnt under water which is reasonable. Will buy again

## Questions & Answers

**Q: How do I set up my ProOne gravity filter for the first time?**
A: Scrub each filter under cold running water without allowing water to go inside the blue stem. After scrubbing your filters, cycle 3 batches of water through them and dump the water. Start drinking your water on the fourth cycle for the best taste.

**Q: How do I prep my ProOne gravity system for travel?**
A: Allow your filter elements to dry out, then wrap them in a cloth and store them in a safe place. If you store filter(s) inside the gravity system, make sure they have ample padding to prevent breakage.

**Q: How often should I clean my gravity systems and filters?**
A: We recommend cleaning your systems and filters at least once a month.

**Q: When and how should I store my filters?**
A: If you are not using your filters or system for more than 4–7 days, drain the water and air-dry the filters. Wrap the filters in a terry cloth towel and store them in a cool, dry place. Do NOT put them in a plastic bag or any enclosed container.

**Q: How many filters should I use?**
A: Each ProOne G2.0 filter has a general lifespan of up to 6 months with daily use. Using more filters at a time will increase their lifespan and flow rate at the same time. Using 3 filters at a time will provide the fastest flow rate.

### ⭐ BEWARE THEY KILLED MY CAT
*by A***A on January 9, 2026*

BEWARE this filter killed my cat! I ordered these from the Proone store and Amazon has since refunded thank you so much Amazon but neither of these filters work. Not only do they not work the PPM increased from my tap water to the filtered water. This is horrible as where I moved to the water is not good. I have used Propur filters for 15 years without issue then Culligan bought them up, turned them to Proone and they no longer are any good. I unfortunately didn’t think I needed to read reviews on a product I have used repeatedly for over a decade. But after reading them now I see I am not the only one. Because of their inferior products I have actually lost one of my cats. I changed out my filters and shortly afterwards, all 20 of my cats started getting diarrhea. I didn’t put two and two together. I changed food, took everyone to the vet spent thousands trying to determine what was going on. all while my older cat declined because we could not stop the diarrhea. I tried every single treatment, putting her through living hell. I was also about to list my house but when your entire household has diarrhea you kind of can’t have ppl coming over as I didn’t want to disrupt my cats and I can’t keep a house showroom ready while managing sick cats. I saw a video on YouTube about someone getting an RO system and a water tester. I thought I would get the water tester just for curiosity sake still not suspecting anything. Once it arrived I tested the water out of the tap a whopping 235 ppm then tested out of the proone expecting it to be in the single digits. Hell to the no it was 257!!! It was worse. I pulled the city’s water report an F one more reason to get out of here. I immediately went and bought RO water ordered a dispenser and started only drinking and using RO water for the cats. Thank goodness diarrhea in 19 cats subsided but my poor Kitten she was so far gone she had wasted away too weak to come back. I had to say good bye to her on 1/6/26 just two days ago. It was so painfully obvious after the fact the what I thought was protecting me and my cats was actually killing us. I have been lethargic and nauseous for a month now not knowing why. I have called, text, emailed and made ticket after ticket to proone without even a response. Except they did sign me up for their newsletter to clutter up my inbox and remind me of how horrific their company has become and how deadly!!! I even posted on their Facebook page, nothing! No response. I reported to Amazon and they seemed concerned. They said they wouldn’t sell their product any more but I see they are still available for purchase. Please for the love of God do not risk getting one of their bad filters I even saw one review where the person tested their lead levels and they were higher after using their filter. What in the world are in these filters that is contaminating our drinking water? We won’t know as this company is too slimy to even respond.
