What Type of Air Filter Is Best for Your Air Conditioning Unit?
are many different types of air filters and air conditioning cleaning systems
used to not only filter the air in your home, but also protect the often costly
heating or cooling equipment used to protect and maintain your unit. In this
article we will cover some of the different types of air filters, and cleaning
systems available to consumers.
we get into the details about air filters and air cleaning systems, it's
important to understand why having a high efficiency air filter is so
important. You might be, or might not be surprised, to find out that the air
inside your home or apartment is far more contaminated and polluted than the
air you and your family breathe outdoors. We are talking about the air you and
your family breathe on a daily bases, most of the time.
The indoor air that you
and your family breathe can be contaminated with micro-particles such as dust,
smoke, and lint. In many homes, pet dander, mold, and bacteria, complicate the
problem even more. In fact, 99% of the particles circulating in your home or
apartment air are one micron and smaller which is less than 1/40th the diameter
of a human hair. These micro particles can aggravate your allergies, and
irritate your respiratory system or simply make your home or apartment dusty
most common air filter that you would find at a hardware store tends to be very
basic only capturing very large particles, therefore not protecting you from
the more dangerous contaminants floating through the air and eventually your
The first step to moving toward cleaning the indoor air in your home is
to pay attention to the MERV rating of the air filter in your unit. A national
organization, ASHRAE, developed the standard for testing air filters. With this
test, the results are expressed in MERV (minimum efficiency reporting value).
Simply stated, the higher the MERV rating, the more efficient the air filter
will be in removing contaminants and pollutants from the airflow.
It is always
best to try and find an air filter that fits your unit with the highest MERV
rating available. If you would like to take it one step further, you can have a
system added to your unit that uses HEPA technology, however this solution is
often very expensive, and the replacement filters are also very costly. While
HEPA filtration is very effective it is often times not necessary. Always be
sure to choose an air filter with the highest MERV rating available.
