What are odors? Why is it a concern for IAQ? First of all odors are an indication of something else going on. For instance: musty odors could signal mold growth and off gassing. Rotting odors could signal bacteria growth. Odors signal something beneficial or harmful in our indoor environment. Odors can signal VOC off gassing which is harmful to the occupants. Odors can signal mycotoxins as small organisms digest their food source of dust, skin cells etc. All of which cause our bodies to have to react to the invaders in our breathing passages. Odors are to be taken seriously, not just a bother.

What is a power surge?
Perhaps you’ve heard this term and now you’re wondering exactly what it
is and why it is so important to prepare for them. A power surge occurs
when something boosts the electrical charge in the power lines. When
this happens, there is an increase in the electrical potential energy,
which can increase the current flowing to your wall outlet.
Power
surges can be caused by any number of things including lightning,
though lightning is not a very common cause. High-powered electrical
devices like elevators, air conditioners, and refrigerators are a common
cause of power surges. Turning these devices on and off creates
sudden, brief demands for power. This can upset the steady voltage flow
in the electrical system, causing a power surge. Faulty wiring, downed
power lines, or other problems with the utility company’s equipment can
also cause surges.
How can power surges be harmful? Many modern electronic devices like
DVD players, computers, and microwaves contain components that are
sensitive to current increases. Computers and any other home appliances
that contain microprocessors are particularly sensitive to power
surges. These devices depend on a steady flow of power at the correct
voltage. Power surges can shorten the life of computers, and
potentially wipe out saved data or destroy the whole system.
In order to protect your appliances from these unavoidable power
surges, it is a good idea to use surge protectors. Surge protectors
help maintain the constant flow of power that appliances like computers
and entertainment systems rely on. Surge protectors can help minimize
or eliminate the damage from small fluctuations in voltage flow, which
can extend the life of your appliances. It can be a hassle to use small
surge protector power strips for all of your appliances, especially if
you own many electronics. To be sure that your whole home is protected
from power surges, whole home surge protection should be used.
