UV does have it's applications.

However, It is expensive for the normal, low maintenance homeowner.
UV does have a 1/2 life...

OK - The Honeywell products are not *that* expensive, and UV is used in
*many* water treatment systems and they are not that expensive... UV
half-life? No. You mean a radioactive half life expressing the rate of
decay? That's like saying light has a half-life, or radio waves have a
half-life - they do not. Half life is an expression of the rate of decay
of a substance (or a biological system) - not the MTBF or service life of a
product. Maybe you mean the phosphors that are used to create the UV
radiation has a half-life?

All things wear out - UV bulbs included, but what I like about some of the
the Honeywell units is that they can sense when the air is moving and then
turn on - extending bulb life past the usual one year.
