Welcome and thank you for your question about the FortiFilter compared to a Lifestraw.
Yes, the FortiFilter functions similarly to a Lifestraw as both are medical-grade ultrafilters. Ultrafiltration (UF) filters like the FortiFilter typically have pore sizes ranging from 0.001 to 0.1 microns (μm), with the FortiFilter specifically having a pore size of 0.01 micron. This pore size is larger than those used in nanofiltration and reverse osmosis but smaller than microfiltration membranes.
When choosing an ultrafilter, pore size is crucial, but another important factor is whether it supports backwashing. Ultrafilters can easily clog due to their fine pores, significantly reducing their lifespan. While some Lifestraw models can be backwashed with an additional tool, the FortiFilter simplifies this process by allowing users to clear the filter by blowing out water from the same end used for drinking.
In summary, both the FortiFilter and Lifestraw are effective ultrafilters, but the FortiFilter's ability to self-backwash enhances its usability and longevity.
