Air Purifiers
There is a growing awareness of the importance
of purified air, especially among
those sensitive
or allergic to pollutants and
dust. Air purifiers
vary greatly between models and
manufacturers.
Before buying an air purifier,
here are some
features to consider:
- functionality - different types of technology are used
to accomplish different types
of purifying.
Purifiers are designed to remove
smells and
odors, remove dust, remove
mold and mildew,
remove allergens and bacteria,
or a combination
of these. Make sure the model
you pick meets
your needs
- size - units can only clean a fixed volume of
air per hour. While larger
units can provide
a wider area of coverage, furniture
and walls
can block air flow and diminish
a unit's
effectiveness. It might be
more effective
to have a smaller unit in each
room than
one large unit for several
rooms. Smaller
units can also be placed on
furniture or
shelving instead of the floor
- maintenance - maintaining the unit is important for
effective operation; understand
the frequency,
cost, convenience, and availability
of parts
required to maintain the unit
- cost - in addition to the purchase price, consider
the ongoing costs of operating
the unit;
fans consume a lot of electricity,
and many
purifiers require replaceable
filters that
can quickly exceed the initial
price of the
unit
- noise - especially important if you are placing
the unit in your bedroom where
fan noise
will disturb your sleep
- automatic timer - so that the unit only runs when you want
it to
- indicator lights - help you know when to cleaning/replacing
filters to minimize maintenance
while maximizing
efficiency
