Maintaining a warm and cozy home during chilly seasons largely depends on the efficiency of our furnace. At the heart of this efficiency lies an important component: the furnace air filter. However, if not properly maintained, furnace air filters can also lead to problems.
Here, we will discuss some common issues affecting your furnace air filters and how to fix them. One of the most important factors is the filter size, usually measured in inches. For example, 16x25x4 furnace air filters are suitable for many standard furnaces, but you should always check the manufacturer’s specifications before buying a new filter.

Clogged or Dirty Furnace Air Filters
Clogging or dirtiness is a common issue faced by furnace air filters, hindering airflow and reducing efficiency. This can lead to increased energy bills, compromised performance, and fire hazards. Signs of a clogged or dirty filter include:
- Reduced airflow from your vents.
- Uneven heating or cooling in different rooms.
- Frequent cycling or short run times of your furnace.
- Loud noises or vibrations from your furnace.
- Dusty or musty odors in your home.
To address this issue, regularly replace your furnace air filter based on the manufacturer’s guidelines. Replacement frequency varies depending on filter type, quality, dust/allergen levels, and furnace usage. Typically, filters should be replaced every one to three months or more frequently for homes with pets, smokers, or individuals with allergies or asthma.

Wrong Size or Type of Furnace Air Filter
Another common problem affecting your furnace air filters is using the wrong size or type of filter for your furnace. This can cause several issues, warns Markham Services, a professional mold inspection company in Tampa area, such as:
- Reduced airflow and efficiency of your furnace.
- Damage to your furnace components.
- Poor indoor air quality and comfort.
- Increased risk of mold growth and health problems.
To fix this problem, always use your heating system’s correct size and type of furnace air filter. You can find this information in your furnace’s owner’s manual or on the existing filter’s label. You should also consider the MERV rating of the filter, which stands for Minimum Efficiency Reporting Value.

Leaky or Improperly Installed Furnace Air Filters
Leaky or improperly installed filters can pose another issue for furnace air filters. Gaps or spaces between the filter, filter housing, or ductwork can allow unfiltered air to bypass the filter, compromising its effectiveness and indoor air quality. Signs of a leaky or improperly installed filter include:
- Dusty or dirty surfaces in your home.
- Increased allergy or asthma symptoms.
- Higher energy bills.
- Lower indoor air quality.
To fix this problem, you should ensure that your furnace air filter fits snugly and securely in its place. In addition, inspect the filter housing and ductwork for cracks or holes, sealing them with duct tape or caulk as necessary. Regularly check the filter for damage or wear and replace it if required.
