Exploring a Brita water filter

“For optimum performance, it is important to change your Brita filter on a regular basis. Replace filters every 151 liters or two months for the average family”


Seeing how they profit from making such a statement, I took it with a grain of salt. Besides, even if they are good intentioned, they are probably giving a safe estimate so they don’t get sued.

Therefore, I resorted to some real world advice from a friend. She said her family has been on the same filter for years. If her family can go off the same filter for years, then mine will probably last forever given that the filter only serves me. Fantastic!

Well, it mysteriously clogged up today. It didn’t slowly clog as one would imagine. It just went nope Jacky, no water for you today. Hmmm…

No idea how these things work, so without further thought, I went out and got a new one.


New one works great, but what do we do with the old one? Since I don’t know anything about these filters, curios Jacky decided to open it up.


This isn’t your causal pop the cap off deal, the top is held on by some strong adhesive. Clearly Brita doesn’t want anyone to do any maintenance here. What kind of “clean” secret is Brita hiding in there?


Since I have already sent this filter on a one way trip down by jamming a scissor into it, might as well take it a step further. For science!


Cap’s off! Well, I was expecting some fancy tech in there. Like layers of different material and stuff. This looks like the soil that was in my plant 😛 (link)


Same stuff all the way down to the bottom


Close up of the material


Hmmm doesn’t look like anything is “clogged” so not too sure why it wasn’t working. My guess would be the pathways in the activated carbon is clogged? But that’s microscopic and not something that me or my camera could see. Regardless, I got to see what is inside a Brita filter 😛
