This and other products roughly similar to Brita filters all seem a bit ridiculous and wasteful. At least this one is glass and so free of plasticizers[1]. A simple drip-through filter isn't going to do that much to improve most U.S. water supplies.

Instead, just get a multi-stage reverse osmosis filter unit. That'll take out virtually everything potentially nasty and/or bad tasting: chlorine, flouride, metal salts used to control algae, misc. minerals and so forth. Coffee and tea brewers, you really owe this to yourselves. The maintenance amounts to replacing a few filters in an under-sink unit every one to three years depending on your local water supply. No remembering to refill a pitcher, just a little extra spigot on your sink.

[1] BPA-free isn't good enough. Replacing one plasticizer with another that also has high estrogenic activity is pointless.

Do you know what a plasticizer does? When it is used? In the preparation of what polymers? This is not an assault, just a hint.

Read up on BPA, then go to your local dept. store's bottle section. Most of the bottles will be made of polymers that do not even involve BPA or BPs, but still advertise as BPA-free. It's only marketing.

You can use a Brita pitcher in places where you're not allowed to install things under the sink, like when you're renting. But most importantly, a Brita pitcher gives you a good excuse to keep your drinking water in the fridge, so you never have to contend with having to drink warm or lukewarm water again.
Thanks--you inspired me to check these out. I'm pleasantly surprised to find that undersink units go for ~$200.
The U.S. has some of the cleanest drinking water in the world.
