Full Product Description

Enjoy safe, clean water anywhere in the world with Sawyer Select Water Filters and Purifiers which remove virtually all contaminants found in fresh water while also improving taste and odor. These systems combine a proprietary foam membrane in an durable silicone bottle with our 0.1 micron hollow fiber filter at the top — ensuring access to clean water in the backcountry, while you travel, at the office, or for emergencies.

The Foam Adsorption Technology used in these systems was developed with a partnership with Foamulations LLC to now be able to safely remove contaminants like heavy metals, chemicals, pesticides, and viruses while also improving taste and odor. Adsorption filtration is the process in which molecules adhere to the surface of the adsorbent foam membrane. This highly advanced filtration and purification process, combined with our 0.1 micron absolute filter will ensure that any and all particulate or pathogens above 0.1 microns are filtered out of your water, including bacteria, protozoa, cysts, dirt and sediment.

Frequently Asked Product Questions

Can I freeze the filter?

While we have no proof that freezing will harm the filter, we do not have enough proof to say it will not harm the filter, therefore we must say that if you suspect the filter has been frozen, to replace it — this is especially true with a hard freeze.

Are the filters and purifiers tested and approved?

Our filters and purifiers have been tested by independent and qualified research laboratories according to EPA standards for water filter and purifiers.

Are there any long term storage instructions for the Select filter or purifier?

You can store the bottle with either the Micro Squeeze filter or included white cap screwed on top of the bottle. The proprietary ingredients in the foam will make sure that your foam does not grow bacteria or develop an odor. Please do not compress these systems for long term storage. Store your bottles fully expanded to ensure that you do not inadvertently shorten their life.If you want to dry out your bottle for packing weight reasons (it can save approximately one ounce), store in a dry room with the lid removed and the moisture will eventually evaporate out. Be aware that after you dry the bottle out, your first bottle will produce much less water than normal since our foam is hydrophilic (meaning it attracts water) and will want to hold onto some no matter how hard you squeeze. Repeat steps for first use when you want to use your filter again.
