Best water filter for traveling? 💧

The next few years are going to be very heavy travel years for me - this Grow Network is demanding so much! (I'm not complaining... in fact I love it, but it's still quite intense).

I've gotten spoiled by very clean, beautiful water for the past years while I was living so remotely. And now, as I'm getting out more, I'm realizing just how bad the water supply in most cities is. Yikes!

What is your recommendation for a good travel water filter? I'm tending to be in a lot of AirBnB's and some hotels. I like to drink at least a gallon each day. More realistically is two gallons per day as I often cook for myself (that's why I like AirBnB's).

Do you have a favorite? Something light and compact...
