Before you start up your heating furnace this fall, take the time to change your filter. Furnace filters are very low cost and are usually
sold in quantity packs to save you even further.
Replacing filters at least once a month not only improves the furnace's efficiency,
but also has other benefits for allergy sufferers.
Low cost furnace filters are usually sold in discounted quantity packs. Replacing filters at least once a month can improve your furnace's
efficiency and help to relieve allergy symptoms. When filters are clogged with dirt and particles and air cannot flow through easily, the
furnace must work harder. Clogged, the filter loses its ability to remove more particles from the air. A furnace that does not work
efficiently, will cost you more in energy bills. To know what type and size of filter you need, pull out the old filter. It would be
located at an easy-to-find spot on the furnace. For easy replacement, note how the old filter was inserted. Most filters have an arrow
and top/bottom noted to make it easier to insert correctly into the furnace. The size and type will be marked on it. Be careful to note
the full dimensions, as even thickness is important. You can bring the filter with you to make shopping easier. Filters are available
from hardware and department stores. There are some filters that are washable, but the low cost far outweighs the time spent trying to
clean and remove the particles.
The 3M Company makes a Filtrete® Micro Allergen Reduction filter that provides better filtration of dust
and other allergens. They cost slightly more than regular filters, but last longer and provide better filtration.
