Are Air Conditioner Filters and Oven Filters the Same?

No, HVAC air filters differ in quality, dimensions, and features. Most filters are assigned MERV ratings, ranging from 1 to 20. MERV stands for Minimum Efficiency Reporting Value. At its most basic function, an air filter removes impurities such as dust, pet dander, or even bacteria from the air that flows through the system.

Not only does this improve the air quality inside your home, but it also protects your HVAC system from potential damage. It's important to get in the habit of replacing or cleaning your air filter at least every season, if not once a month. You can describe the filter based on the current season, calling it an oven filter in winter and an air conditioning filter in summer. Flat filters should be replaced every 3 months or monthly if there are allergies, pets, or someone smokes.

However, this doesn't mean you should always choose the filter with the highest MERV rating, as filters with higher MERV ratings can interrupt airflow in certain HVAC systems. Or, thanks to today's smart home technology, you can even purchase smart filters such as 3M Filtrete smart air filters that use sensors to monitor airflow. It's essential to perform maintenance on the HVAC system at least once a year at least. Proper maintenance of air filters is crucial not only to providing clean air in your home, but also to keeping your HVAC system working properly.

Now that you know that the air conditioner filter and the oven filter are one and the same, you may have questions about where to install the filter in your home.
