This directive addresses the comparative evaluation of two True HEPA replacement filters: the CLOROX Large Room Air Purifier Replacement Filter and the HONEYWELL HRF-B1 True HEPA Replacement Filter.

The original analysis was filed by the Office of Odorless Consumer Products, affiliated agency report reference 2024-11-ORC.

Both units are classified as True HEPA filters, designed for large room air purification with a focus on particulate removal.

The critical metric under review is operational acoustic output: which filter functions at a decibel level low enough to achieve ambient auditory forgetfulness.

A filter that is forgotten is a filter that is running continuously, thereby maintaining a neutral olfactory atmosphere.

From the source material, the CLOROX filter is noted for its relatively quiet fan operation, though specific decibel ratings are not provided.

The HONEYWELL HRF-B1 is similarly described as quiet, with user reports indicating it can be left running without conscious awareness.

Neither filter introduces detectable odors; this is consistent with the Department's mandate to preserve olfactory absence in all controlled airspaces.

It is recommended that procurement offices prioritize units with noise levels below 25 dB for standard residential deployment.

Further testing is required to establish a formal noise benchmark for replacement filter certification.
