5. Sawyer Products Select Series Water Filter bottle
Highlighted Features
The Sawyer S3 can bring the dirtiest water to be clean and drinkable in a mere 10 seconds, making it one of the fastest working filters on our list. Boasting a massive list of hardness particles, the S3 water filter is a great option for those of you on-the-go. Packing it is extremely easy due to its foldable, squeezable design.
It also features a 0.1 Micron filter making it one of the best-filtered water bottles for travel. The filtering bottle uses two distinct stages to remove bacteria and other contaminants. The first stage is a foam filter to target bacteria, protozoa, odors, and other chemicals. The 2nd stage removes anything leftover and looks for viruses and heavy metals to remove from the water.
It’s lightweight and easy folding system makes the Sawyer S3 a great option for water bottle filters, but its performance does not leave anything to be desired either. Even if you’re not a traveler, you can use this at home or in the gym and still reap the benefits.

7. Brita 36387 Premium Water Filter Bottles
Highlighted Features
Brita is a home-leader in water purification products and has been for many years. This premium filtered water bottle is no exception. The wide variety of colors and options are a nice feature right off the bat, but more importantly, it does its job when it comes to filtering the water.
One thing I loved about this Brita self-purifying water bottle was the weight. It is super convenient, weighing only 7.7 ounces and is easy to carry when it is full or empty. The design of the bottle is a longer, more slender shape, which made it easy to keep in a cupholder or the side pouch on my backpack.
When it comes down to the nitty-gritty, the Brita product is a fan favorite thanks to its reliable brand name and its ability to provide clean and odorless drinking water with no bells or whistles. If you are looking for a larger, easy to carry a bottle, this may be your choice.

10. Sport Water Bottle with Filter
Highlighted Features
Hikers and campers are going to love this self-filtering water bottle. It is fully collapsible and squeezable, which gives it so many uses. You can use it as a simple water bottle or use the squeezable bottle to clean or wash dishes while on the campsite.
The nozzle at the top of the bottle did not reduce the water flow by any means, and it was super easy to drink with. By simply pulling the nozzle up, you have access to water that is purified and filtered. There is no straw in this bottle, which can be convenient as those types can sometimes take a while to filter water out.
The packability and durability of a fully collapsible and squeezable bottle is my favorite feature. You can literally roll it up into a small plastic bundle and save so much space in your bag or backpack. While it’s full, it is a nice carrying loop for easy carrying.
