Moisture
Meters: Measure/Monitor Moisture Levels in Building Materials
Moisture meters may be helpful for
measuring the moisture content in a variety of building materials
following water damage. They can also be used to monitor the process
of drying damaged materials. These direct reading devices have a
thin probe which can be inserted into the material to be tested
or can be pressed directly against the surface of the material.
Moisture meters can be used on materials such as carpet, wallboard,
wood, brick, and concrete. |

Gauges or Meters: Monitor Moisture Levels in the Air
Humidity meters can be used to monitor humidity
indoors. Inexpensive (<$50) models are available that monitor both
temperature and humidity.
Humidistat: Turns
on HVAC System at Specific Relative Humidity (RH)
A humidistat is a control device that can
be connected to the HVAC system and adjusted so that, if the humidity
level rises above a set point, the HVAC system will automatically come
on.
HVAC System Filter:
Filters Outdoor Air
Use high-quality filters in your HVAC system
during remediation. Consult an engineer for the appropriate efficiency
for your specific HVAC system and consider upgrading your filters if appropriate.
Conventional HVAC filters are typically not effective in filtering particles
the size of mold spores. Consider upgrading to a filter with a minimum
efficiency of 50 to 60% or a rating of MERV 8, as determined by Test Standard
52.2 of the American Society of Heating, Refrigerating, and Air Conditioning
Engineers. Remember to change filters regularly and change them following
any remediation activities. |
