“The 40% Rule: Why Humidity is the Key to Home Health.”

The "Bio-Hazard" Zone When your home's humidity drops below 35% (common during our -20°C nights in Russell and Embrun), your house enters the "Active Zone" for:

• Viruses: Flu and cold viruses stay airborne longer in dry air.

• Bacteria: Respiratory infections spread faster in low-humidity environments.

• Respiratory Strain: Your body’s natural defense—mucous membranes—dry out, making you more susceptible to infection.

  
  

The Solution By maintaining a "Nominal" range of 40% to 60% humidity, you aren't just improving comfort; you are creating a "Kill Zone" for pathogens. As shown in the chart below, this is the optimal window for human health.
