Why a HEPA air purifier?
Everyday we typically inhale
the equivalent of two heaping tablespoons of airborne
particles that our bodies must process and eliminate.
The smallest of these particles can be inhaled and end
up settling deep inside the lungs in areas where the body's
natural mechanisms can't remove them and this in turn
can cause the greatest harm.
Air
purifiers draw in these particulates and filter them
out of the air you breathe.
The effectiveness of air
cleaners in removing pollutants from the air depends
on both the efficiency of the device itself (e.g., the
percentage of the pollutant removed as it goes through
the device) and the amount of air handled by the device.
For example, a filter may remove 99% of the pollutant
in the air that passes through it, but if the air flow
rate is only 10 cubic feet per minute (cfm), it will
take a long time to process the air in a typical room
of 1000 cubic feet. |
