Prevent the Spread of Airborne Contaminants

Captures particles at the source

Our innovative family of products enable users to limit the transmission of respiratory particles including while administering respiratory treatments and procedures in a portable negative pressure environment.

SafER treatment and transport

You can turn any setting into a negative pressure environment to reduce airborne particles.

Product Kits

The plug and play SafER Portable Negative Pressure System™ is a customizable system useable in many environments.

Our system is flexible and inexpensive yet delivers tremendous value to organizations by preventing exhaled particles from entering the environment while allowing for treatments and procedures as well as user mobility.

CFD Study Executive Summary

A computational fluid dynamics (CFD) study was performed to characterize the performance of a new respiratory shield. The study was intended to assess the ability of the respiratory shield in removing micron-sized water droplets. The suction, located at the base of the respiratory shield, creates an inwards flow of air towards the user which removes over 93% of 0.5 micron sized particles exhaled. The remaining particles are suspended within the shield or re-inhaled by the user. The study also showed that when the user is given inhaled medications the intended level of medication is still delivered to the user from the nebulizer and ventilation system with this innovative air containment system.

Summary and Observations

May see an average of 99% effectiveness in removing exhaled particles from the work environment.

  • Captures 93% of particles exhaled by user(240 L/min)
  • Enables re-inhalation of particles not yet removed from air (6%)
  • 1% of exhaled particles remain in flow domain (after re-inhalation)

Suction system does not reduce the number of nebulizer particles delivered to users receiving inhaled medications.
