A air purifier replacement filter. The pleats are what do the work – they multiply the surface area so air keeps moving through as the filter loads up.
The activated carbon layer is the part that handles smell rather than particles – cooking, pets, smoke – which a plain pleated filter will pass straight through. Filterbuy builds more than 600 sizes, so an odd opening is usually a stock item rather than a custom order.
Filterbuy has manufactured pleated air filters in the United States since 2013, at plants in Alabama, Pennsylvania, Texas and Utah. The company grew out of Talladega Machinery & Supply and employs around a thousand people. This filter is made in the USA.
