Things To Know When Choosing Your Portable Water Filter

Last updated: September 17, 2026 Dan DeBaun By Dan DeBaun

Water has always been considered the universal thirst quencher and something we could never live without. Portable water filters make it convenient to filter water on the go, cutting down on single-use plastic and saving money compared to bottled water. The popular Berkey Sport water bottle filter does just this.

Why A Portable Water Filter?

Investing in something like the Sport Berkey bottle filter can add up to real savings compared to a steady habit of bottled water. All you need is one portable filter bottle, and the case of bottled water on your counter starts to disappear. It's inexpensive and frees you from spending a few dollars a day at the store or a vending machine.

If you're picturing a bulky system resembling the countertop unit at home, that's not the case. The Sport Berkey is 11 inches tall, 2.5 inches in diameter, and has a loop for clipping onto a bag or belt loop. The convenience of a reliable, high-quality filter bottle you can refill throughout the day is the main reason people switch to one.

Portable water filters come in different shapes, sizes, prices, and levels of performance. Our most popular option is the 22-ounce Sport Berkey. It uses an ionic adsorption microfiltration process to reduce chlorine, taste and odor, and a range of chemical contaminants when refilled from treated municipal tap water.

The Sport Berkey is built to reduce many common chemical contaminants found in treated tap water, and it's simple to use. When you first receive your bottle, flush the filter with water twice to clear manufacturing dust, and you're ready to go. From there, refill it from a tap water source and squeeze to drink.

The Sport Berkey filter provides clean-tasting water over a long duration of use. The filter inside is rated for about 640 refills from a treated tap water source such as your home, car, or office before it needs to be replaced. Rinsing it after use and letting it air dry will help the filter maintain its integrity. Once the filter reaches the end of its rated capacity, simply swap in a Sport Berkey replacement filter, a process that takes about 30 seconds.
