What type of oven filter is right for you?


Anyone who lives in a cold weather climate knows how important your home stove is. Keeping your oven running at its most efficient capacity is important not only for your heating bills, but also so that the life of your oven is not shortened by having to work harder than it should.

An oven circulates the air inside your home through an intake, passes it through the oven filter to remove dust particles and impurities, heats the filtered air and then sends it out through the various ventilation ducts throughout your tube furnace.

The oven filter is an important part of heating your home, and it can be harmful for your oven to forget to replace this filter regularly. Fortunately, it is a simple task to replace your oven filter that can be performed by even the least practical homeowner.

A dirty oven filter does not catch as many dust particles circulating through your home as a clean filter will. This can be especially bothersome for people who suffer from allergies or asthma. A dirty oven filter also reduces your oven's energy efficiency, leading to higher bills and possible expensive repairs. In some cases, maintaining your furnace filters may not lead to hazardous conditions, including house fires, because the clogged filter does not allow enough air through.

By changing your oven filter regularly, you save money, improve air quality and protect the moving parts of your oven itself.

Furnace filters are classified on a scale called the MERV (Minimum Efficiency Reporting Values ​​scale), an efficiency rating from 1-20, although most home filters only go up to approx. 12 on the MERV scale. A lower MERV rating means lower efficiency from the filter.

When choosing a furnace filter, consider the type of furnace you have, how much money you want to invest in maintenance, and how often you want to change your filter.

Disposable fiberglass

The cheapest and probably least effective oven filter setting is the disposable fiber filter. With a MERV rating of 2-3 and a price typically below $ 2 each, this filter is approx. 1 inch thick of spun fiberglass. It can trap larger particles of dust, lint and dirt from clogging your oven, but does not filter out smaller objects from getting through. These filters are great for renters or those who do not have allergies or asthma.

Disposable pleated

A popular filter because they are relatively inexpensive and offer more filtration properties than the fiberglass version at a price of $ 4 to $ 5 each with a MERV rating of 6. These are constructed of polyester or cotton paper and will trap particles such as spores and mites. These filters are denser, therefore add more resistance to airflow and often need to be replaced so they do not clog or tax your oven system, making it less efficient and more expensive to operate.

Disposable electrostatic

These filters contain self-charging electrostatic cotton paper fibers that attract and trap small particles such as pet hair. A MERV rating of 10 and a price of approx. $ 10 each puts them in the middle of the road in terms of efficiency and pricing compared to other filter options. Good for homes with pets and smokers, these are great for standard size oven filters, but if your oven requires a custom size, the cost can be high if you replace them on an ongoing basis as needed.
