When it comes to air filters, don't be fooled by the FPR hype. Home Depot filters, such as Honeywell and Rheem, are not necessarily bad, but they can be deceptive and overrated. The Filtrete AC oven air filter is presented as the best overall oven replacement filter, with a high-efficiency MERV-12 rating that captures microscopic allergens and a lifespan of about three months. If you can't find Nordic Pure in your size, or if you need a new filter right away, Honeywell's FPR 9 filters and Filtrete's MPR 1500 filters are similar and widely available in retail stores.
The filter is only available in two sizes: 16 inches by 25 inches by 4 inches and 20 inches by 20 inches by 1 inch, so make sure to measure your current filter before purchasing the Honeywell extended-use filter. Filtrete uses exclusive 3-in-1 technology to trap lint, dust, pet dander, soot, pollen and mold spores while allowing fresh air to flow through the filter. It also comes with Bluetooth technology to monitor filter usage. If you don't have a Honeywell, Aprilaire, Space-Gard, or Trion Air Bear unit (which are the brands Honeywell can replace), you can find branded replacement filters for other brands.
For those looking for a filter that goes in your home's return air filter, you can generally find 17 different sizes under the Honeywell brand. For a more durable filter, check out the Honeywell Home MicroDefense AC air filter that lasts up to 12 months before needing to be replaced.
