The ZShield Reveal comes with a replacement filter, based on average exposure and usage, we recommend replacing your filter cartridge once per week or after 40 hours of use, whichever comes first.
Your needs may vary based on environmental and personal usage considerations. In very dusty or contaminated environments, you should change your filter cartridge more frequently.
