I would avoid thefiltered water from your condo since the bacteria that many of us are susceptible to can accumulate in filter systems. A LifeStraw pitcher is on my counter that I use it for tea, coffee and making ice-cubes, etc. I have a LifeFilter squirt bottle for travelling or drink bottled water if it's labelled spring water. These are precautions for MAC bateria so I"m not sure it they aply to pseudomonas. Check discussion posts on pseudomonas.

I disinfect my showerhead and kitchen faucet when I remember every couple of months. You can find older discussion posts about how different people do this.
