RELATIVE HUMIDITY IN THE HOME
According to the (EPA) Environmental Protection Agency relative humidity should be between (30-60% RH).
Excess moisture can cause mold and mildew growth on surfaces.
Building materials provide nutrients for mold to grow.
Mold growth will occur on sheetrock or drywall, behind wallpaper, porous materials such as wood studs, and upholstery materials.
Mold will feast on materials until total decay.
REDUCING RELATIVE HUMIDITY INDOORS
- Controlling Indoor Temperature
- Air Conditioning
- Increase Air Movement
- Dehumidifier
- Air Breach in Windows, Door Seals
- Moisture Leaks
- Fix Faulty Plumbing
- Control Foundation Moisture
- Control Condensation
- Reduce Vapor Pressure
HOW TO TEST FOR RELATIVE HUMIDITY
Relative Humidity is measured by a Hygrometer.
The accuracy from device to device can range up to 10% plus or minus.
This is a huge discrepancy! Accuracy is important when determining indoor moisture problems.
Equipment should be factory calibrated to assure accurate readings measuring the 30-60% threshold for relative humidity tolerance.
