North Air-Purifying respirators are intended to be used for respiratory protection against hazardous
vapors, gases and/or particulate matter, depending on the air-purifying elements used
and the contaminant concentration and/or toxicity; but only if there is sufficient oxygen present
in the contaminated atmosphere to support life. These respirators are approved by the National
Institute of Occupational Safety and Health (NIOSH) and are suitable for use in workplaces
regulated by the Occupational Safety and Health Administration (OSHA). If you have converted
this respirator to a supplied air respirator, use the Instructions for Use that accompanied the
Airline Accessory.

North 7700 Series Half Mask Respirator
The 7700 Series is the most comfortable and durable half mask available. Its soft nonallergenic silicone seal provides excellent protection, comfort and fit. The half mask cradle suspension system allows the facepiece to seal evenly on the face without creating pressure points. Its low profile gives workers a wide field of vision and does not interfere with protective eyewear. The low inhalation and exhalation resistance of the 7700 Series makes breathing easier to reduce worker fatigue.
Features and Benefits
- Silicone facepiece material conforms to facial features and doesn't harden with age. Silicone is easy to clean, extremely durable and resists distortion ensuring a better fit, time after time.
- Contoured sealing flange and cradle suspension system eliminates discomfort caused by pressure points on facial nerves. Design of nose area provides excellent comfort and fit.
- Minimal dead air space improves worker comfort by limiting re-breathing of exhaled air.
- Direct cartridge to facepiece seal minimizes replacement parts and simplifies maintenance.
- Three overlapping sizes will comfortably fit most users.
- North 7700 Series Half Masks are compatible with all North cartridges, filters and accessories.
