When it comes to furnace filters, the nominal size is used to simplify the size of the filter. For instance, one of the most popular oven filter sizes is 20 x 25 x 1 inch, but the actual size of the oven filter measures 19.5 x 24.25 x 0.75 inches. Both sizes are printed on the sides of the filter for your convenience. To guarantee you get the right size filter for your furnace, it's important to measure the existing filter or consult the manufacturer's specifications. This will enable you to find a larger and stronger oven filter that will improve your indoor air quality and energy efficiency.
Generally, oven filters with a thickness or depth of one inch should be changed more often. The length, width and depth of a filter are printed in small numbers along the filter frame, on the cardboard edge of a Filter King brand filter. If you're having difficulty finding the right size air filter for your air conditioner, you can look for the model number on the filter near your central furnace or air conditioning unit. This will help you locate the right size air filter for optimal energy efficiency and appliance performance. Most people won't find the size of air filter they need at their local home improvement store. The size of the oven filters determines how effectively they can clean the air and contribute to energy efficiency.
It's important to replace oven filters with a thickness or depth of up to one inch once every one to three months. Choosing the right air filter size is essential for reliable performance and energy conservation. If you ever find yourself in need of a new air filter, make sure you take all necessary measurements and consult with a professional if needed. When selecting an oven filter, it's important to consider not only its size but also its MERV rating. MERV stands for Minimum Efficiency Reporting Value and it indicates how effective an oven filter is at trapping particles in the air. The higher the MERV rating, the more efficient an oven filter is at trapping particles such as dust, pollen, pet dander, smoke, and mold spores. The largest furnace filter size available is typically 20 x 25 x 5 inches.
This size is ideal for larger homes with multiple rooms and high levels of air pollution. It's important to note that this size may not be suitable for all furnaces, so it's best to consult with a professional before purchasing a new furnace filter.
