      • Layer 3 (middle):

        • High-efficiency, melt-blown, non-woven polypropylene that can filter smaller substances.
    • How long will a PM2.5 filter last?
      • With respect to our PM2.5 filters, it is recommended that the filter be replaced after a maximum of 12 hours of use. For instance, if you use the filter continuously at work for 8-12 hours a day, it is recommended that you replace the filter after every single use. If you use the filter occasionally for 1-2 hours at a time, you may be able to reuse the filter more than once, up to a maximum of 12 hours. Another useful rule of thumb is to replace whenever inhalation resistance increases – when it becomes harder to draw a breath, even if the 12-hour maximum use time has not elapsed.
