## Description

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

## Features

- 5-Stage Efficient Filtration: With adoption of premium-quality coconut shell activated carbon, 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. If the water flow decreases or the filter has been used for a long time, you can remove the mouthpiece, flush it with clean water.

- Versatile Uses: The Water Filter Straw can be connected with water bags or water bottles to filter water for drinking. Both ends of it can be disassembled and connected with the water bags and the water bottles to offer you clean drinking water anytime anywhere.
- Warm Prompt: If the gravity bag is used to filter water, turn on the drainage valve first to empty air from the hose before connecting with the straw to avoid no water flow in a vacuum state.

### ⭐⭐⭐⭐⭐ Absolutely Exceeded Expectations!
*by J***N on August 8, 2025*

Absolutely Exceeded Expectations!I took this on a 2-night hike in the woods with a Trail Life troop — 8 adults and 11 kids — and this water filter performed beyond what I imagined. It provided clean, fresh water for everyone, and we even had extra water left over. It was reliable, easy to use, and incredibly effective. No complaints at all — we all loved it. Highly recommend for any group camping or hiking trip!Will be buying a second one

### ⭐⭐⭐⭐⭐ Great value!
*by B***N on August 9, 2025*

Easy to use. Fairly fast flow rate. Good quality (in 2 weeks, I've filtered about 14+ gallons through the filter without any issues). Back flushing is simple. Not a major deal, but the only thing I'd like to see is an adapter for the 28mm (soda bottle) threading so it would fit other size bottles/bags. Compared to other brands it a great value.

### ⭐⭐⭐⭐ Well designed and good value
*by S***H on August 17, 2025*

Very good alternative to the bigger brands. The gravity flow works well. The filter slowed down considerably after a few gallons, but was re-useable after flushing. Well designed water bag.
