GETTING THE MOST FROM YOUR AIR CLEANER
For greatest efficiency, the air cleaner should
run all the time. To do this, set the fan switch on
your thermostat to ON, and make sure the air
cleaner is switched on. The fan and air cleaner
will run even when the furnace or air conditioner
is off. Note: A manual fan switch may be built
into the furnace fan controller.
The air cleaner itself uses less power than a
40 watt light bulb (two-cell model—33 watts;
single-cell model—22 watts). You will also have
the cost of running the system fan to consider.
Generally the added cost is more than offset by
the added benefits of full time air cleaning and
improved air circulation. Some people feel that
room temperatures stay more even when the
fan is always on.
Even if your thermostat does not have a fan ON
position, you can obtain maximum available air
cleaning benefit by making sure the air cleaner
is always switched on so it operates whenever
the furnace or air conditioner is on.
Although the air cleaner is designed to be
efficient over a wide range of cell loading
conditions, regular cleaning is your best
assurance of consistent performance. Also, a
very dirty cell and prefilter reduces air flow and,
in turn, this reduces the efficiency of the furnace
or air conditioner.
