Face Mask, North N95 Filter

thingiverse

Cartridge replacement for North Brand Mask is a straightforward process. First, replace the regular cartridge with an 80mm N95 prefilter. This will ensure that you're breathing in and out through the same filter, protecting both yourself and those around you from potential airborne contaminants. To do this, simply attach the adapter and one prefilter in place of the exhaust check valve. Print caps can be used to block off the regular cartridge attachments, further safeguarding your health. However, please note that using a cap will only protect you, not others nearby. Alternatively, if you prefer, you can use N95 prefilters as direct replacements for the standard cartridges. While this approach won't safeguard those around you, it's still an effective solution for personal protection.
