RZ Mask F1 Mask Filter - 3/Pack - Large

F1 STANDARD ACTIVE CARBON FILTER: 3/PACK

The F1 is our standard filter consisting of two filter layers, the outer particulate filter, and the internal active carbon element. The outer layer of the F1 filter is capable of trapping particulates down to .1 micron in size. The inner layer, known as the Active Carbon element is effective towards fumes and odors. Combining the two technologies this filter has been laboratory tested to be 99.9% effective. 

How long does an RZ Filter last? 
The life expectancy of the RZ Filter depends on many variables, such as; particulate exposure density, particulate exposure duration, and user breathing rate. With that said, below are our general guidelines – as the user will have the final call given your exposure.

+ 20-30+ hours of continuous use in heavy dust exposure to things such as; grain bins, off-roading, construction/demolition, etc.

+ 30-40+ hours of continuous use in light dust exposure to things such as; grain bins, off-roading, construction/demolition, etc.

+ 50-60+ hours of continuous use when protecting against allergens, pollutants, odors, etc.
