A small countertop water cooler/dispenser with a refillable filter bottle on top. (if you have the floor space, a stand up cooler is usually more energy efficient tho)
Something like this:

With one of these on top: https://www.zerowater.com/products/filtered-water-cooler
Clean filtered water, both boiling hot and almost ice cold, on-demand. Filling water bottles, cups, making hot chocolate, tea, instant noodles, even just starting to boil a pot using pre-heated water, taking so much less time. I love this thing.
When it comes to filters:
Zerowaters products specifically come with a Total Disolved Solids meter measuring in parts-per-million.
I was previously using a Brita filter jug which poured into a second filter from Aquapur ontop of my cooler.
My Tap water: 143ppm
Brita filter: 139ppm
Brita+Second filter: 87ppm
Replaced both with a single zerowater filter: 0ppm
After pulling close to 30 gallons through that filter its risen to ~8ppm (they want you to replace it at >6)







You don’t.
Seprate your work life and your personal life.
There’s nothing wrong with advocating for FOSS alternatives; but you don’t get to decide what you can or cannot use on work devices, that’s up to your employer. You should not be entering personal info/performing personal tasks on work devices.
If you’re unwilling to perform work with the tools (software) your employer provides/requires, find a new job. Refusing to do the work or tampering with the equipment provided is a great way to get fired.
For school; personal laptop. Or again strictly school tasks on their devices.
