How hard is it to suck water through the straw?Updated 3 months ago

Our tap water filter is surprisingly easy to drink from. In fact it makes drinking water more enjoyable than drinking from a glass. 

Our Everywhere Water Filter requires a little more effort as the filter is capable of removing 99.99% of contaminants from highly contaminated water, and it removes bacteria, viruses, and cysts from water which are tiny! So we think it's worth a little more effort. ;)
