MIRA Safety MB-90 Powered Air-Purifying Respirator Blower

The MB-90 is designed for use with the MIRA Safety CM-6M and CM-7M gas masks, and is compatible with other NATO-CBRN standard gas mask platforms that use the standard CBRN blower connection port.

Yes. The MB-90 includes a CBRN-rated P3 filter meeting EN 143:2021 standards (99.95%+ efficiency) for protection against particulates, biological aerosols, and radioactive particles. NBC/CBRN combination cartridges providing protection against chemical agents are also compatible.

The MB-90 is designed to CBRN military-derived standards and not marketed as a NIOSH-approved PAPR under 42 CFR Part 84. It is intended for emergency preparedness, HAZMAT response, and military applications. For OSHA-regulated workplace use, consult your respiratory protection program administrator.

The MB-90 provides 4+ hours of continuous operation at full 280 L/min flow. For extended operations, carrying a spare charged battery is recommended.

The MB-90 is designed for the MIRA Safety CM-6M/CM-7M gas mask connection system. Compatibility with standard industrial full-face respirators depends on the blower output fitting. Consult MIRA Safety's current compatibility guide before using with non-MIRA equipment.

CBRN stands for Chemical, Biological, Radiological, and Nuclear — the four threat categories relevant to military, first-responder, and emergency preparedness applications. CBRN-rated filters are tested and certified against a broader threat spectrum than standard industrial respirator cartridges.

The MB-90 attaches via a belt clip and connects to the gas mask via a breathing tube. Its compact design minimizes interference with tactical gear, body armor, or other emergency responder equipment.

The MB-90 delivers 280+ L/min — more than double the NIOSH minimum of 115 L/min and significantly higher than many industrial PAPRs (typically 170-200 L/min). This creates strong positive pressure within the mask, reducing inward leakage risk.

The included P3 filter provides 99.95%+ efficiency against particles, including wildfire smoke particles. For chemical vapor hazards in wildfire smoke (such as VOCs from burning structures), a CBRN combination cartridge is required.

Charge the MB-90 battery via the included USB-C charger. A full charge typically restores battery capacity in 2-3 hours. MIRA Safety recommends storing batteries at 50% charge when not in use for extended periods.

The MB-90 is used by HAZMAT teams, emergency responders, and military units requiring CBRN-level protection with reduced breathing fatigue. Confirm with your agency's respiratory protection program that the MB-90 meets your specific hazard and regulatory requirements.

Check MIRA Safety's current compatibility documentation for the TAPR mask. The MB-90 is primarily designed for the CM-6M/CM-7M series. Contact MIRA Safety directly to verify compatibility with specific mask models not listed in standard documentation.
