Product Description

A woman drinking water from a clear glass. Text reads: ProOne water filters
A water filter. Text reads: High-quality filtration. Helps reduce over 200 contaminants.

  • 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.

  • 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.

  • We recommend cleaning your systems and filters at least once a month.

  • 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.

  • 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.

As you probably know, if you're ordering this replacement filter, these are great! Best tasting water ever. But the product image, showing 2 filters, is misleading. Read the print, you are just getting 1 in your order.

I purchased these as a back up set for my Berkey Travel filter. My Berkey, which I absolutely love, came with two black carbon filters. I have read that the ceramic filters are much better because they filter out fluoride as well so I purchased two of them with the intent of replacing my black carbon filters. But my black carbon filters are only about Six months old so I think I’ll use them for a while longer and just keep these as back up.

Loved the 2.0 filters. Worked great and lasted quite a while. These new 3.0 filters are absurdly slow. 12 hours to filter less than a gallon. Please bring back the 2.0

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.

They come with a cleaning pad, so you can clean them and reuse for much longer than recommended. I tested the water from a 1 year old filter and a new one. The results were the same except for the new one filtered out the chlorine slightly more.They are ceramic.
