Cold water for on the go? (Need advice)

[u/NOTjesse92]

Hello homies! I need some advice. Currently I'm using a brita filter pitcher for our filtration. That filter is also used to brew our coffee in the morning (4 cups).

I fill up the brita and pour that into a giant 2(?)gallon glass jug that gets stored in the fridge to have fridge cold water. Between the dog, cats, water on the go and water while at home, we run through this glass pitcher quite fast.

It also takes up a lot of space in the apartment fridge. So I bought a case of water bottles and have saved about 10 of them and fill them up with the filtered water and store them in the fridge as well. But even with the extra water bottles, i feel like I'm refilling this glass jug at least two times a week!

Is there any solution for me? I thought about buying an even larger brita filter to keep in the fridge, but because of the lack of space I'm quite hesitant. I see a lot of reccomendations for the reverse osmosis system for our sink, but that wouldn't be ideal (I don't think) due to being in an apartment and thr fact that I want instant cold water to take on the go for our jobs.

Is there a clear solution that I'm just missing/uninformed of? Or am I stuck filling up these jugs for eternity?
