Essick Air FILTERWATCH 127-001 - Manual (Page 3)

The CADR is the single most important thing to know about air purifiers.
CADR is the amount of clean air (in cubic feet) the machine, with its filter, will
deliver into a room. It measures the net effect of the filter material and the air
flow of the unit.
No other measurement tells you how well a unit works in your home. The
higher the CADR rating on a specific particulate matter, the more efficient
that model is at removing that particulate. As you can see from the AHAM
CADR ratings seal above, the True HEPA Media Air Purification System is a
state-of-the-art appliance which, when used in accordance with the instruc-
tions, will clean the air in a localized area in your home or office. The True
HEPA Air Purification System is specially designed to help eliminate dust,
pollen, smoke, viruses, bacteria, and other allergens from the air.
Secondly, it is good to know exactly what area or room size you wish to
clean. This air purifier will remove 99.97% of the airborne particles entering
the unit, and will clean a 18 x 14 square foot room with 5 air charges per
hour, based on the CADR rating of the product. Air Purifiers may be used in
any room in the house. Typically, they are used in rooms where people spend
the most time: the bedroom and the family room.
Remember, opening a door or window will introduce more airborne particu-
lates to the room and, therefore, increase the time indicated to clean a room.
