Everyday I find myself frequently refilling our brita water filter pitcher. This is a good thing because it means that my family is drinking a lot of water everyday instead of pop or sugary drinks. The brita pitcher is one of the most used items in our home, so I can confidently state that it's a great buy.
I haven't changed the filter out in a year or so, even though they recommend changing the filter out every month or two. I don't know if the change recommendation is due to brita needing to sell filters or because I really should be replacing the filter every month.
Do carbon filters really go bad and stop filtering? I haven't noticed a change in the flow rate of the water being filtered in my brita pitcher. It appears to be filtering the water fine.
I've even tested out the filtered water for chlorine... as I was curious to see if an old filter 6 months or older could no longer take out the chlorine from the tap.... and I found that the filtered water from the old brita filter was still chlorine free.
