Because my son and I got thru stages in water consumption, the '2 month' sticker on my Brita Pitcher isn't always accurate. I would love some kind of indicator on the filter itself showing when it needs changed. (much like the one on my fish filter and humidifier filter) I would have no problem switching it more often if/when it needed it, but I tend to hang on the filters a little longer because I do not want to be replacing it when it 'seems' like we haven't been using it much... And if I saw a warning, I would be less inclined to let it go - we all want the freshest water!!

I use my Brita pitcher to cut down on the amount of plastic I use, as well as to avoid adding garbage to landfills. I would love if Brita could create a biodegradable or recyclable filter to aid me in my quest to reduce my carbon footprint!
A lot of people and myself that dye or bleach their hair have trouble maintaining the color. The minerals in the water dull or tint the color and leave a residue on the hair even after being washed. A Filtering shower head would be AMAZING. I think it would sell great in hair salons or in stores.
I would like to see Brita water pitches in smaller sizes that kids can handle. Decorate them with characters kids love to get them to want to drink more water! The combination of being able to do it themselves and loving the container wil help encourage water consumption.
A huge plus to using Brita filtered water opposed to bottled water is the fluoride. I recommend pumping up the advertising about this fantastic fact. Filter out the bad but keep the good. Especially important for kids - so make sure doc offices and dentists get coupons to set out that will reach the parent audience. And I can just imagine cutesy commercials with crazy little toddlers running around being bad but taking a minute to get a glass of water from Brita filter with a halo forming around head. Just an idea..
Call me crazy but why shouldn't my two sweet dogs and my sweet cat have the luxury of a Brita water filter?
Wouldn't it be great if you could have Brita filtered water anywhere you go? It would be awesome to have a special Brita Water Bottle with a snap-on and snap-off filter at the top so when you refill it, no matter where you are, you can have wonderfully clean Brita water :)
It would be great to have brita filters available to install in public places-drinking fountains.
