What You Need to Know About Furnace Filters
If you were asked to name components of your furnace, you would mention filters, but how much do you know about these filters? While furnace air filters are likely the least of your worries, they should be a top priority. Without an air filter, your furnace won’t be effective or efficient. Here is everything you need to know about a furnace air filter.
Why Does My Furnace Need a Filter?
Furnace filters help improve the furnace’s efficiency by decreasing dust or particle buildup in the furnace’s air ducts. Thus, they allow free airflow within the system, improving its efficiency.
Filters also help improve the health of household members since they remove irritants and allergens from the warm air as it circulates around the home. After filtering the air, there is a lower chance of someone with allergies getting a reaction.
What Size of Filter Does My Furnace Need?
Knowing the right filter size for your furnace will help you buy the right filter size when making replacements. It will also help prevent damage and furnace repairs. But how do you know the right size of filter for your furnace?
When you remove the current furnace filter, you will find a label on the filter with details about the filter’s length, width, and height. If there is no old furnace filter to refer to, you can consult a HVAC specialist for filter information.
What Are the Different Kinds of Furnace Filters?
There are different types of furnace filters in the market, each serving a certain purpose best. The most common type of filter is fiberglass filters since they are the most affordable and offer the least air resistance.
Other types include pleated filters that are expensive and more effective than fiberglass filters. Electrostatic filters are disposable and washable, while carbon filters are best for trapping gasses.
What Are MERV Ratings?
MERV- Minimum Efficiency Reporting Value is a filter rating that measures the size of debris the filter captures. A high MERV rating indicates the filter can collect smaller quality.
To enjoy better air quality, go for a higher MERV rating. The ratings range from 1-16. If anyone in the house has allergies, aim for a rating not below 12.
