It's always a bit of a surprise to pull out an old stove filter and see how much dust it's collected in a few months. My particular system uses a 2" x 20" x 20" filter - a size not always available at home centers. "big box"." meant - and I found that filter , which were offered by local providers, looked quite low quality in terms of the degree of filtering. As an allergy sufferer I was happy to be able to purchase a higher level of filtering which should reduce the movement of allergens, although the air conditioning in my home these filters serve my needs very well and are fairly reasonable. In my house, the furnace is in the attic and the filter is just behind the grille on the ceiling of the central hall. Filter sizes are typically slightly smaller than nominal, allowing for a "three-handed" installation (solved by turning on a system fan to allow airflow to hold the filter in place by covering the grille holding the filter). in place.) The filter is not in close contact with the walls of the filter box, but the air duct behind the filter is slightly smaller, so the air pressure holds the filter to the air duct during operation and provides an adequate seal. The filter looks solid and should do the job. without destroying the structure.
