LifeStraw’s pitcher comes in a bunch of options, including a glass container, which we think is one of the best-looking pitcher filters around. There are also several colorways to complement your countertops or kitchen decor, and all models come in both 7 and 10 cup capacities.
One thing to note: If you’re interested in the glass version of the LifeStraw home as a no-plastic alternative to standard pitcher filters, this probably isn’t’ the product for you. While the aesthetics of the glass pitcher are great, the section housing the LifeStraw filter remains constructed from plastic, so filtered water can still come into contact with a plastic surface when the filter is especially full.
The LifeStraw home combines three types of filtering to produce a best-in-class pitcher, which is capable of removing nasty tastes, smells, bacteria, microplastics, and other common harmful contaminants.
Alongside the micro membrane that catches contaminants over 0.2 microns in size, an activated carbon filter is used to adsorb organic (carbon-based) chemicals such as chlorine. Added to these two stages is an ion exchange resin. This filtering process removes ions dissolved in water (including heavy metals like lead) by exchanging them for non-harmful ions bound to the filter fibers, as the water passes through.
LifeStraw’s three-stage filtering process makes it unique among the pitcher filters we’ve looked at, in that it’s the only model able to reduce or remove PFAS. PFAS are an emerging drinking water contaminant in the US, often derived from industrial foams as well as many household chemicals found in food packaging and stain repellents.
Here’s the Performance Data Sheet for Lifestraws Home pitcher.
LifeStraw sets different lifespans for the different elements of their filtering system, which may cause annoyance for some users. Their Membrane Microfilter is estimated to last up to 264 gallons, or 1 year of regular use in areas where water isn’t especially hard or contaminated. The activated carbon and ion exchange component of the filter has a much shorter shelf life, at approximately 40 gallons, or 2 months.
Further complicating the filter replacement process for the LifeStraw is the fact that the pitcher contains no filter indicator, and that replacement filters may be more difficult to source than other cartridges from more mainstream brands. One reviewer from Canada noted that they were only able to buy extra filters from the LifeStraw US website, costing them extra for shipping.
LifeStraw don’t submit their products to the industry-leading certifying body, the NSF. However, they do claim to test their products to NSF standards via their own labs and third-party overseas certifiers. According to the brand, their filter meets NSF standards:
- 42: improves the taste and smell of water.
- 53: reduces or removes listed harmful contaminants
- 401: reduces up to 15 emerging contaminants cited by the NSF.
- P473: reduces PFAS chemicals below the EPA healthy advisory limit (70 pp trillion)
Lots of reviewers of the LifeStraw Home were big fans of this product’s design, with one describing it as “classic with a hint of the science lab.” At the same time, others found the glass version frustratingly thin, resulting in them having to be overly careful when using it.
