Review: Travel WIN!!!! - Came home from Uzbekistan with the worst case of what my grandma used to call the “gogo-amago” ever. Figured it either came from carelessly rinsing iur toothbrush in tap water, or eating a fresh fruit washed in tap water. Made an advance plan for our next trip to a third world country. No salads. No fruit unless we washed it ourselves. No smoothies unless they used bottled water. Don’t use room water provided unless we saw them filter it ourselves. Have a plan in place to provide so we won’t dehydrate and for tooth brush. This little gizmo is AMAZING. It is lightweight, super easy to pack, easy to use once you get the hang of it, cheap to use, and saves tons of plastic. My only fear is, the straw part is very sturdy, and so far the bag part is, too, but it seems much more likely to wear out, crack, or get punctured (even though it’s a thick plastic) than the straw. I wish they’d include and extra bag or two, as well as instructions to clean and store straw and bag. Well worth what seems to be an initial “investment”. Other travelers were jealous, and asked for details. Will be packing it for our next trip, to rural Morocco. Wouldn’t dream of traveling without it now. Has earned a spot in our minimal packing. Os: bought extra straws, but it seems like these things last forever. Hope we’ll get to travel enough to use the extras! ## Features - 5-Stage Efficient Filtration: With adoption of premium-quality 0.1 um ultrafiltration membrane and other raw materials, the Water Filter Straw can effectively reduce harmful substances like chlorine, particulates, sediment, stones, sand, dirt, bad taste &odor in water to ensure the water safety and deliver better drinking experience. - Professional Combination: Waterdrop Gravity Water Filter Straw with 1.5 gal Gravity-Fed Water Bag is an exclusive water purification combination created for outdoor activities and first aid survival. The large-capacity water bag can hold up to 1.5 Gallons of water at a time, which is about 11 bottles of 500 ml bottled purified water, and can meet the all-day demand for outdoor water drinking. - Longer Lifespan: The Waterdrop Filter straw can provide safe drinking water up to 1,400 gallons (5,300 liters), and ensures the maximum water flow rate of up to 700 ml/min to provide more relaxed outdoor water drinking experience. - Recyclable Straw: With innovative backwash purifier function, the inside of the Water Filter Straw can be kept clean at all times and it is recyclable, safe and pollution-free.

I bought a second after being so pleased with this one. Flow rate is superb compared to competitor products. We had one or two days where an algae bloom heavily covered the surface water of the lake. We filtered water all week without problem. Backflushed easily on day 5 with clean water and was amazed to see the amount of algae and dirt that came from the back wash. Restored back to original flow rate. The bag is durable but I could see it getting damaged if not protected or stored properly. The water tasted good for the price point. Compact space saving design. ## Frequently Bought Together - Waterdrop Gravity Water Filter Straw, Camping Water Filtration System, Water Purifier Survival for Travel, Backpacking and Emergency Preparedness, 1.5 gal Bag, 5 Stage Filtration, Pack of 2 - Waterdrop Gravity Water Filter Straw, Camping Water Filtration System, Water Purifier Survival for Travel, Backpacking and Emergency Preparedness, 1.5 gal Bag, 0.1 Micron, 5 Stage Filtration, Blue - Aquatabs 397mg Water Purification Tablets (100 Pack).
