Why it earns a place

Useful preparedness gear should make sense before an emergency. Learn it on ordinary trips, maintain it, and know its limits before conditions are difficult.

Product details & specifications

Don’t settle for anything less than crisp, clean air. The Air Sentry 300 by UltraLux Health delivers powerful multi-stage filtration to a 300-square-foot space — no matter where you live.

The Air Sentry 300 is designed to capture and reduce:

  • Dust and pet dander
  • VOCs and PM2.5 particles
  • Smoke and airborne particles
  • Common household odors

With the Air Sentry 300, air in your space is cycled approximately every 10 minutes through a True HEPA 13 filter that captures 99.97% of particles 0.3 microns or larger.

Fresher air. Noticeably cleaner. You’ll feel the difference.

Shipping & returns
