Airborne debris like dust, dander,
pollen, allergens are very harmful to your health and lungs. However, there’s a
debate among the health community about the airborne nature of the COVID-19
virus. Whether the COVID-19 is an airborne disease or not, you shouldn’t take a
risk when it comes to your health. A furnace filter prevents all these airborne
particles from entering your body. Also, it protects the blower motor of your
HVAC system from dust and debris.
Furnace filter replacement is an
integral part of HVAC maintenance. It improves the quality of the air and
protects your HVAC components from dust and small particles. In this article,
I’ll give you the ultimate guide to furnace filters, including its types, costs,
things to consider and many more.
Ultimate Guide to Furnace Filter
Filter Types & Things to Consider
There’re different types of furnace
filters available on the market. It’s crucial to select the right furnace
filter for your HVAC system, especially when it comes to producing clean,
sustainable, and healthy home environment. You’ll have to consider a few things
before choosing the right furnace filter for your HVAC system. For example –
filter size, thickness, and efficiency of the filter.
The furnace filter is located on the
side door of your furnace’s filter cabinet. There are different furnace filter
sizes available on the market. But you should only choose one which fits
snuggly to your filter cabinet. If the furnace filter isn’t exact to the size
of your furnace filter cabinet, small particles and dust will do harm to your
HVAC system, and you won’t get the clean air. Many HVAC manufacturing company
produces its own furnace filter that is compatible with your furnace filter
cabinet and your furnace model.
Another thing which you’ll have to
consider is the thickness of the furnace filter. Generally, furnace filters are
1 to 5 inches thick. For longer use, you should buy the thickest one. However,
you should consider your HVAC system configuration, which determines the ideal
furnace filter thickness.
Furnace filters are disposable, and
you’ll have to change the furnace filter after a few days. However, there’re
some furnace filters that are reusable, and you can use it again after washing.
Some of the available furnace filter types are-
- HEPA or High-Efficiency
- Synthetic or Fiberglass
Now, I’ll tell you the cost associated
with furnace filter replacement.
Filter Replacement Cost
You maybe are worrying about the
furnace filter replacement in this difficult time. But don’t worry; it is
affordable. Few factors determine the value of a furnace filter, such as the
thickness of the furnace filter, MERV value, materials, model of your furnace,
etc. Based on these factors, a furnace filter can cost you $10 to $40 at most.
A fiberglass 1-inch furnace filter with low MERV value will cost you only a few
bucks, but it has a demerit. You’ll have to change the furnace filter
frequently. On the other hand, a pleated 5-inch furnace filter with a high MERV
value will be a bit costly, but it’ll last for a year. Most of the house owners
in the US prefer to buy this furnace filter as you don’t have to change the
furnace filter frequently. So, if you’re confused about buying a new furnace
filter, you should go with high MERV value and thickness.
You may be wondering what MERV value
is. Now, I’ll give you a brief idea about MERV value.
is a MERV Value?
MERV stands for Minimum Efficiency
Reporting Value. This rating is used to determine the efficiency of a furnace
filter. MERV value ranges from 1 to 16. Higher the value is, the more efficient
your furnace filter is and capable of removing small particles from the air. To
determine the ideal MERV value for your HVAC system, you should consult with an
HVAC professional. He/she will consider the indoor air quality and your HVAC
system to tell you the ideal MERV value. This will help you to utilize the
maximum capacity of your furnace and have clean air in your house.
Frequent Should I Change the Furnace Filter?
This completely depends on the
thickness of the furnace filter. If you buy a 1-inch furnace filter, you’ll
have to change the furnace filter every 3 months or 60 to 90 days. On the other
hand, if you buy a 5-inch furnace filter, you’ll have to change the furnace
filter once every year.
