Does the new bottle have an odd smell?
A slight odor is normal for brand-new TPU bottles. Simply rinse it thoroughly with clean water before first use, and the smell will fade quickly.
Why does very little water come out when I use it?
The filter needs to be fully soaked in water beforehand for smooth flow. Prime the filter with water before use, then you will get steady water output.
Do I need to squeeze hard to get water out?
The filter naturally slows down the water flow. Just apply moderate pressure for smooth water output. Made of 0.4mm TPU, thicker than the common 0.3mm material, it is durable and easy to squeeze.
How to clean and maintain this filter bottle daily?
Cleaning is super easy. Rinse the bottle and filter with clean water and shake gently. No backwashing needed. Just air dry thoroughly before storing it.
What water sources can this filter be used for?
It fits freshwater, perfect for camping, hiking, traveling and daily use. Do NOT use it on heavily polluted water or water with high heavy metal content.
