PM Sensor

PM Sensor detects changes in indoor air quality, activating a response in real-time while proving its performance

The PlasmaGuard PM Sensor provides real-time feedback of particulate levels to the PlasmaGuard Smart Hub, signaling the patented PlasmaGuard Generator, installed in your HVAC system, to respond to air quality changes. This in-room sensor works by pulling in the air at a constant rate, drawing airborne particles through the laser particle counter, and reporting results every 90 seconds.

When the sensor detects that particle levels are too high, based on user-determined thresholds, the generator is notified, and the system operates until the sensor verifies that your air is purified and again within your target air quality levels.


  • Proprietary patented response technology

  • Continuously monitors indoor air and responds to changes in real-time

  • Measures particulates down to 0.3 microns in size including PM1, PM2.5, and PM10

  • Reduced particulate levels are proven on LCD indicator

The science of air and surface purification

When particulate levels are too high the PlasmaGuard™ PM Sensor activates the patented PlasmaGuard™ Generator. The Generator, which is installed in your central HVAC system, uses our patented bi-polar cold plasma process to begin sending an overabundance of natural high-energy ions through all of your air ducts.

Our patented blend of natural, long-life, positive, and negative ions flood every room and begin the purification process. Each register in your home or business becomes an air and surface purification system.

  • Neutralizes up to 99.99% of tested viruses, allergens, odors, and bacteria in occupied environments*

  • Reduces airborne aerosols and particulates in the breathing zone such as PM1, PM2.5, and PM10*

  • Patented PlasmaGuard O2 Catalyst converts unwanted ozone into oxygen*

  • Reduced particulate levels are proven with the PlasmaGuard PM Sensor’s laser particle counter

  • 5-Year Limited Warranty

Smart Hub

The Smart Hub immediately signals a response to changes in indoor air quality.

When a change in your indoor air quality is detected, the PlasmaGuard™ PM Sensor notifies the PlasmaGuard Smart Hub™, and the patented PlasmaGuard™ Generator is signaled to respond. The system operates to continuously purify indoor environments until the Sensor verifies that you have achieved your target air quality level. The Smart Hub then signals the Generator to enter standby mode, if your HVAC system is not actively operating.

The Smart Hub is compatible with popular digital assistants including Amazon Alexa and Google Assistant, as well as Zigbee-enabled smart home protocols and cloud-connected home automation devices. The Smart Hub is covered by a 2-Year Limited Warranty.
