Will a Dirty Furnace Filter Make Your House Dusty?

Oven filters separate dust and other dirt particles from the air that circulates around the house. When these filters become dirty or clogged, they are unable to perform this task, resulting in more dust and debris circulating throughout your home. This dirty air will settle on surfaces, spreading contaminants such as dust, dirt, pollen, pet dander, bacteria, plant and fungal spores, and even smoke. A clogged or dirty air filter can also restrict system airflow, forcing your HVAC system to work harder and consume more energy.

This can make ducts dirty and leave a lot of extra dust throughout the house. Additionally, dirt on the fan blades is a sign that your filter needs to be replaced. A dirty filter won't be able to protect your air conditioning system either. Your oven can only be as efficient as if it is properly maintained.

Particulate buildup due to a dirty air filter can reduce efficiency, increase service calls, and prematurely fail the unit. All the dust you see on the used filter is dust that is removed from the circulation in your home. However, when the filter becomes clogged, the system cannot efficiently clean dust from the air, so much of it remains in the living space. Cleaning and dusting your home regularly is a good way to extend the life of your oven filters.

A clogged oven air filter will adversely affect airflow throughout the house and the HVAC system. The lack of fresh air in the oven will cause the heat exchanger to become too hot and deactivated. Dirty filters indirectly cause short cycling problems and will make it difficult to maintain heat in your home. We recommend replacing the clogged air filter before the summer season to avoid damaging the air conditioner compressor.

If you have some furry friends in your house, this could definitely be a cause for oven filters to dry out quickly. Allowing the filter to get too dirty can cause the oven to run short cycles or cause the air conditioner to freeze. Leaving them untreated can not only destroy your oven filter quickly, but it can also lead to higher energy bills. One of the purposes of an air filter is to filter out all microscopic particles, such as dust, pollen, pet dander, bacteria, plant and fungal spores, and even smoke. Flat filters and media filters are physical barriers that trap particles as air moves through them.

Keeping the oven air filter clean will also prevent dust accumulation in the ducts and may extend the life of the unit. If the filter becomes too clogged with dust, dander, and dirt, the fan will have to work harder to get air through the clogged filter. This can mean higher energy bills than normal, premature system wear and tear, and polluted air so your family can breathe. Not all filters are created equal, and filters with a higher MERV rating may be more successful at trapping particles as air moves through them. To ensure that the air in your home is safe to breathe, it is important to continuously replace the oven air filter to prevent dirt and debris from seeping into the air supply. Pleated filters made of disposable nonwoven fabric have smaller pores than flat surfaces, allowing them to hold more particles than a flat surface. Replacing your oven filter frequently will help keep your HVAC system running efficiently while keeping your family safe from pollutants.
