Clear Flow Filter Replacement

(5 reviews) Write a Review

The Clear Flow Filter Replacement has been rigorously tested and surpasses EPA standards for removing E. Coli, Giardia and Cryptosporidium, and many other waterborne contaminants. The Clear Flow filters down to 0.1 microns without the use of chemicals, iodine or batteries. But the Clear Flow Filter Replacement goes one step further than most competitive products and also reduces heavy metals, such as iron and lead. The Clear Flow also reduces many chemicals found in the water supply as well as improves the taste and color of the water. Competitive products that only use hollow fiber do nothing to remove the dirty taste of water or improve the color of the water. It may be safe to drink, but it is still going to look and taste like dirty water. With the Clear Flow the water will be safe to drink and will actually look and taste good.

Once the Clear Flow filter has reached its capacity (1,500 liters / 400 gallons) it will no longer allow water to pass through it. The filter easily detaches from the bottle and can simply be replaced.

The filter replacement measures 5.75" x 1.25" and weighs only 2 ounces.

    I was so happy they had these replacement filters for my Clear Flow! Got mine last week and it was beyond easy to pop it back on my water bottle and go.

    I'm glad they have a replacement filter for my water bottle now. Bought the clear flow a couple years back and the flow rate wasn't as good anymore. Got one of these & my water bottle is like brand new again.

    worked just fine but kind of thought I could have just bought a brand new water bottle that comes with this already.
