For just over $10, this NatureNova straw features a four-stage filtration system (including hollow fiber membrane, activated carbon, and PP cotton) that claims to eliminate 99.999999% of microscopic contaminants down to 0.01 microns. According to the product description, each straw can filter up to 1,500 liters (or 396 gallons) of water, which is quite typical for filters of this kind.
It’s designed to be highly portable and weighs less than 3.5 ounces, making it easy to pack in a bag. It also includes several useful accessories that are not always provided with inexpensive straws: an extension tube so you don’t have to get too close to the water source, and a backwash syringe to assist in cleaning the filter and possibly prolonging its lifespan. You can also attach it to standard water bottles.
