Allergy Furnace Filters - Can They
Alleviate Your Allergy Symptoms?
See Allergy Furnace Filters
Indoor air pollution can often result from dust mites
and pollen; pet hair and dander; reduced air circulation and
ventilation; high concentration of organic materials; and chemicals from
common household products such as toluene, chlorine, or even
formaldehyde. These contaminants can then lead to exacerbated allergy
symptoms such as hypersensitivity pneumonitis, sneezing, watery eyes,
and other respiratory disorders.
Fortunately for allergy and asthma suffers, allergy furnace filters are
a relatively inexpensive way to clean the air, and they have been shown
to be over 90% effective at capturing larger particulates from the air
such as dust and dander. These high efficiency air filters come in the
form of pleated panels that are inserted into the filter opening of a
home's furnace or air conditioning unit, and they are perfect for asthma
or allergy sufferers, as they do not use harmful ionizers or ozone to
remove pollutants. Some allergy furnace filters can be washed or reused,
but many models are conveniently disposable, and can be tossed when
dirty.
An allergy furnace filter usually consists of a frame and filter media.
The frame allows the filter to withstand the pressure created by the
heating and air conditioning system. When choosing a high-efficiency
allergy furnace filter, look for models that are composed of highly
specialized, synthetic filtration media, as these provide a combination
of electrostatic and mechanical filtration to ensure sustained
performance. The gradient layer of this media has the ability to capture
particulates while minimizing airflow resistance, and will not absorb
moisture that will lead to the growth of microorganisms such as bacteria
and mold.

How an Allergy Furnace Filter Works |
Also, another factor to consider when choosing an
allergy furnace filter is the Minimum Efficiency Reporting Value, or
MERV rating. This measurement is a rating of a filter's ability to
capture larger particles between 0.3 and 10 microns, and can be very
helpful in comparing the performance of various furnace filters. The
higher the MERV rating, the more effective a filter is at trapping
specific types of particles.
Lastly, another added benefit of using an allergy furnace filter is ease
in maintenance. Installation is usually quite simple, as no tools are
required. To install an allergy furnace filter, follow these simple
steps:
1. Remove any plastic or paper wrap from the filter, and do not cut,
crimp, bend, damage, or remove the cardboard frame around the filter
media.
2. Remove and dispose of the existing filter in your home furnace or air
conditioning system, and keep in mind that the used filter can contain
particulates that, with improper handling, can be re-introduced into the
air. Immediately place the soiled filter in a plastic garbage bag, tie
the top, and dispose of it properly.
3. Insert the allergy furnace filter in the filter opening of
your home furnace.
Be aware that while allergy furnace filters are very effective at
trapping harmful particulates, they are best used in combination with an
air purifier as part of an all-out campaign to reduce airborne
allergens.
