What is the Best Furnace Filter to Buy?

If you are concerned about indoor air quality, the best furnace filter to buy is a disposable electrostatic filter. These filters contain self-charging electrostatic cotton or paper fibers that attract and trap small particles, and they have a MERV rating of 10. This makes them an affordable and effective solution for homes with children, pets, or smokers. Custom sizes are available, but they can be expensive if replaced regularly over several years.HEPA filters are very dense and can reduce the airflow entering the oven, so they are generally used only in commercial ovens or hospitals. With a MERV rating of 16-20, they block the highest level of particles in the air and provide better air quality.

However, they are not suitable for most residential ovens. Oven filters come in dozens of sizes, with the three most common being 16 by 20 inches, 20 by 25 inches and 16 by 25 inches. The thickness of the filter varies from one to five inches, and in general, the thicker the filter, the more particle blocking capacity it will have. Before choosing a filter, you will need to consult the owner's manual or operating manual, as not all ovens accept a thicker product. As the filter becomes thicker, the oven must work harder to draw air through it, reducing its efficiency and service life. The Filtrete AC oven air filter is presented as our best overall oven replacement filter.

The preferred type of oven filters are pleated and electrostatic disposables because of their ability to filter lint, dust, pet dander, soot, pollen, and mold spores. While many picks are unable to filter out smoke and bacteria, most of these options come in various sizes and thicknesses to be compatible with your oven. As for MERV ratings, most of the above products range from 8 to 12 without impeding airflow. The selected selections listed above may last longer than 2 to 3 months at a time, but for convenience some will last longer than 12 months or come with multiple filters. Special features such as arrows included in the frame to direct placement and airflow; odor control; HEPA filters; Bluetooth capability; car emissions; humidifier dust; Legionella; tobacco smoke; bacteria; virus carriers; microscopic allergens; etc., are also available. According to a CNN article HEPA filters with MERV ratings of 17 to 20 are best at reducing the spread of viruses but most household ovens cannot draw air through a dense HEPA filter.

Many oven filters need to be changed every 2-3 months so many options come with 4-6 filters per purchase but some options may last 9 to 12 months before requiring a replacement. Oven filters are an important part of maintaining good indoor air quality so make sure you choose one that fits your needs!.
