Frequently AskedQuestions

How do I know when it is time to replace my filters or when they have stopped working?

The LifeStraw Activated Carbon and Ion Exchange filter lasts approximately 40 gallons (150 liters). We estimate that it should be replaced every 2 months. This assumes that a household uses approximately 2.5 liters per day or refills the 7-cup filter housing approximately 5 times per day. If you are using the product less, you can adjust your estimate of length of time needed before you must replace the activated carbon and ion exchange filter. Another way to tell if the filter has reached its lifetime capacity is if you can detect that the taste of your water has returned to the original tap taste. This may be more apparent for some people than others. Heavy metals and chemicals rely on prolonged exposure to cause sickness so if your activated carbon and ion exchange filter has a short lapse in timespan, you should not be at immediate risk.
The membrane microfilter lasts 264 gallons (1,000 liters). We estimate that it should be replaced once per year. This filter ends its lifetime when flow rate becomes drastically reduced or completely blocked out of the filter. It will never allow bacteria, parasites or microplastics to filter through it. This is critical as these contaminants can cause immediate sickness unlike most chemicals and heavy metals found in water.

Does your filter measure total dissolved solids? How does it perform against them?

In general, concentration of heavy metals such as Lead, Mercury, Cadmium, Chromium, etc. in tap/ground water (excluding sewage, industrial waste water) is only in ppb level (part per billion) and is extremely low compared with concentration of normal minerals such as Potassium, Calcium, Magnesium, etc. in the same source of water which is in ppm level (part per million)
Our activated carbon fiber and ion exchange filter is specifically designed to selectively remove heavy metals while keeps healthy minerals in the water through a complex process: physical adsorption resulting from Van der Waals forces and chemical adsorption where chemical bonds are formed to trap heavy metals in the porous and high surface area of the adsorbent material. In theory, this process can reduce TDS in the water but only in µg/L level which cannot be detected by a normal reading when taking into account the deviation of TDS in raw water (e.g city tap water), accuracy/repeatability of TDS meter & measuring operation.
In general, we caution against the use of TDS as a measure of efficacy and you can read more about why on our recent blog post: https://www.lifestraw.com/blogs/news/do-you-know-what-s-in-your-tap-water

What is the capacity of the filter? How long does it take to fill?

It takes approximately 5 to 6 minutes to filter each batch (filling the filter housing to the top). It takes about 3 fills to get to the bottom of the handle (which is the max fill line). The capacity is 7 cups (approximately 1.66 liters).

Product description

The award-winning LifeStraw water filter technology has evolved with the addition of a 2-stage filtration system and a sleek, durable steel straw body. In addition to the hollow fiber membrane found in the original LifeStraw personal water filter, which filters out virtually all bacteria and protozoa, the LifeStraw Steel offers the additional benefits of a replaceable activated carbon capsule, which reduces chemicals such as chlorine as well as organic compounds—including pesticides and herbicides—for up to 100 liters. The result is better tasting and odor-free water, straight from the source. Removes a minimum 99.9999% of waterborne bacteria (>log 6 reduction) and surpasses EPA standards for water filters, and removes minimum 99.9% of waterborne protozoan parasites (>log 3 reduction) and filters to an amazing 0.2 microns. As with the original LifeStraw, the LifeStraw Steel requires no batteries, pumping or waiting, providing quick access to clean water on-the-go from lakes, rivers, and streams. The food-grade stainless steel housing is sturdy and meets FDA standards, and the sleek, portable design makes it ideal for camping, backpacking, and international travel. An essential component of any emergency prepardness or disaster survival kit, no home, car, or bugout bag should be without one. The filtration straw includes a steel cap for extra durability. Membrane filters up to 1,000 liters. Measures 9 x 1 x 1 inches; weighs 4.2 ounces. For each LifeStraw purchased, one child in a developing community receives safe drinking water for an entire school year
