These simple charcoal water filters are easy to use. Put in your water and each removes absorbs impurities. Every other week boil the filter. I use one in my Brida water in the fridge; I use the other in my teapot. I exchange every other week. Read more

These work fantastically! The water tastes so much better than regular filtered water, and the charcoal sticks are easy to use, plus they look so much better than the plastic filters. Also, these are so much better than the plastic versions, last longer, make the water taste better, and look so much better in the water pitcher. Read more

My water tastes better with these in it. I put one stick in a 2 liter glass bottle of tap water and wait 4 hours for the water to filter. I use 2 glass bottles and 2 sticks and alternate use. I used to use Zero water pitchers but I want to avoid microplastics, if possible, which is why I made this change. Boiling the stick for 10 minutes every 2 weeks refreshes it for another use, and is not too much of a pain if you do it while you're cooking or doing other stuff around the kitchen. Read more

Have only been using these filter sticks for a month but am happy so far. Bought these as an alternative to expensive pitcher filters, which worked fine.... but the cost! I believe it said it would filter 2 qts in 3-4 hrs but I find that our water needs at least 5 hrs to filter to the taste we prefer. To be honest I was skeptical about these but am glad I decided to take a chance and try them. Would definitely recommend. Read more

I would not agree with reviewers who claim the water tastes amazing. It tastes like water with the heavy minerals from the tap filtered out. One of the two logs severed in a 90-10 split, immediately, but I do not think this is a failure of the product. My 2L vessel has an undulating design, and it caused an impact. Just be careful with them to avoid damaging the integrity of the structure. Product provides valuable utility. Read more

I really like this product. It’s easy to use, sustainable, and instructions are super easy to follow. I really like that there are two charcoal sticks in one box. I recommend! Read more

I would have given this more stars except the water doesn’t always taste good. I’ve used this for about a week. I fill up a 4 L pitcher with tapwater and put two of the sticks in. I find that leaving it overnight works best. When I pour a glass of water in the morning, there’s zero taste of tapwater and it’s excellent. However, if I don’t finish the full glass of water and leave it out for a few hours, then the icky taste of tapwater comes back. I have no idea why that is. I don’t have that phenomena happen with bottled water. Read more

I order these every 6 months through Subscribe & Save to put in my water pitcher I fill from the tap. I keep the pitcher in the door of my fridge and let it steep over night and the water tastes much better. Been using them fr a few years now. Read more
