I originally purchased three filters and a large 22-cup dispenser just to try it out. I'm happy I did! I recently bought another replacement pack because these filters just plain work. The lifespan isn't as long as I might like, but that's because the water where I live has a very high TDS, it's not the fault of the filters. All considered, it is still way cheaper than getting water in one of those big jugs.

This is by far the best pitcher-style water filter I've found. The other big names don't even filter the stuff I care about, like lead. The expensive under-the-sink contraptions are great, but I don't own a home and don't want to sink the money into one yet. These are the perfect middle for me: they filter the water very well, don't break the bank and are dead simple to use. The difference between drinking ZeroWater filtered water and tap is pretty shocking now! I didn't realize how nasty my water was!
