Easy Fix for Airlock Issue

One common issue that some users have experienced with the LifeStraw Flex Advanced Water Filter is the tendency to get an airlock in the tube between the water bag and the filter. When this happens, the flow of water is significantly reduced. However, there is a simple solution for this problem. By using the syringe provided with the product, you can attach it to the filter end and pull the water down into the line and filter, filling the whole thing with water. After squirting out the water from the syringe, the whole system will be primed and water will filter and flow freely.

Perfect for Outdoor Adventures

Many customers have praised the LifeStraw Flex for its performance during outdoor activities. One user mentioned that their sons used the filter during a hiking trip and were extremely satisfied with its performance. The filter successfully removed any strange taste from the water, leaving it clear and drinkable.

Reliable Water Source

Another customer shared their experience of using the LifeStraw Flex for a week at a lake. They solely relied on the filtered water from the lake and never felt sick. They also mentioned that initially, the drip was slow, but after figuring out how to remove air bubbles, the flow became much faster. They recommended using a jug to let the water filter into and then filling water bottles from that, ensuring a passive water supply.

Emergency Preparedness

While hoping to never need it in an emergency, a customer appreciated having the LifeStraw Flex as a precautionary measure. The product provides peace of mind knowing that they have a reliable water filter that can remove potentially harmful substances.

Minor Design Improvements

Although generally satisfied with the LifeStraw Flex, one customer suggested a few minor design improvements. They mentioned that it took some time to get the hang of using the filter, and the water flow was occasionally disrupted by wind. They also wished for a faster way to refill the filter while it was hanging. Overall, however, they stated that the water tasted excellent, and they remained healthy throughout their trip.

Cons

  • Limited Gravity Bag Capacity: While the gravity bag is a convenient component of the LifeStraw Flex Advanced Water Filter, it has a capacity of only 1 gallon. If you’re in a situation where you require a larger volume of filtered water, you may need to refill the bag multiple times, which could be time-consuming and inconvenient.

  • Filter Replacement: Although the LifeStraw Flex Advanced Water Filter’s membrane microfilter has a long lifespan, the activated carbon and ion exchange filter needs to be replaced after filtering approximately 26 gallons (100 liters) of water. While filter replacements are readily available, it’s important to keep track of the filter’s usage to ensure optimal performance and maintain a supply of replacement filters.

  • Gravity Bag Durability: Some users have reported that the gravity bag may not be as durable as expected, with concerns about leaks or tears over time. It’s recommended to handle the bag with care and avoid excessive strain or rough treatment to ensure its longevity.

This means you need to physically suck the water through the straw or hang the gravity bag to allow water to flow through the filter. While this may not be a significant issue for most users, it’s worth noting that it requires some effort compared to automatic filtration systems.

the LifeStraw Flex Advanced Water Filter with Gravity Bag offers versatile filtration options, efficient purification, and a positive social and environmental impact. While there are a few limitations to consider, these are outweighed by the product’s many advantages.
