Air3 Respirator by MicroClimate

the smartest, most comfortable PAPR respirator on the market.

The Air3 is a lightweight (just 3.17 lb / 1.44 kg), positive-pressure powered air-purifying respirator engineered for all-day comfort and reliable protection against airborne particulates. Its patented monocoque manifold design dramatically reduces weight and part count while delivering exceptional balance, so users can work for hours without neck strain or fatigue.

Standout Features

• Industry-leading visibility — Largest field-of-view visor available; users can comfortably wear glasses and even use facial recognition on their phones.
• Beard-friendly & no fit testing required — The loose-fitting, positive-pressure design eliminates the need for a tight face seal, making it OSHA-compliant for bearded workers and dramatically simplifying respiratory protection programs.
• First NIOSH-approved respirator with USB-C charging — Onboard lithium-ion batteries deliver over 8 hours of runtime; fast USB-C charging gets you back to work quickly. Add an optional external battery pack for truly unlimited runtime.
• Glove-friendly operation — Large power button, clear multi-color LED status indicators, and audible alarms for low battery or airflow.
• Tool-free maintenance — Filters, visor, and shroud can be swapped in seconds with no tools required. Electronics are conformal-coated for durability in harsh environments.
• Quiet & powerful — Delivers a steady 7 CFM (200 L/min) of HE-filtered air (99.97% efficient) with an Assigned Protection Factor (APF) of 25.

Proudly designed and built in Provo, Utah, the Air3 combines American engineering with practical innovation at a price that makes high-quality respiratory protection accessible. Whether you're in construction, manufacturing, remediation, welding (particulates only), or any environment with solid or liquid airborne particulates, the Air3 delivers serious protection without the usual compromises in comfort or usability.

Simple. Tough. Comfortable. Made in the USA.
