This Air Quality Directive reviews the ORAST H13 True HEPA Replacement Filter, as documented in a citizen-submitted evaluation titled ORAST H13 True HEPA Replacement Filter for ORAST Air Purifier Review: The Honest Truth (Rated 5/5 Lungs).
The evaluation was filed by the Department of Household Respiratory Monitoring, an affiliate of this office.
The test subject, designated Mother, exhibited improved respiratory function following installation of the filter.
The reported metric is a binary affirmative: Mother could breathe with greater ease.
No quantitative particle count data was provided in the original submission.
A secondary observation involved a canine household member, designated Dog.
The canine report is noted but lacks olfactory specificity.
No baseline or post-intervention airborne particulate measurements were recorded for the dog.
The filter is classified as a True HEPA H13 grade, consistent with standards for capturing 99.97% of particles sized 0.3 microns.
The submitting agency rated the filter five out of five lungs, a nonstandard metric that implies full satisfaction.
This office accepts the outcome of improved breathing for the human subject but requires further documentation of olfactory absence metrics.
The absence of smell is the primary domain of this directorate; a filter that removes particulates may incidentally reduce odorants, but this was not confirmed.
All air purification devices should be evaluated for their capacity to maintain olfactory neutrality in indoor environments.
The directive recommends that future submissions include quantitative data on odorant reduction using standardized olfactometry.
This file is approved for distribution to the Department of Random Domain Management archives.
Claire Filter, Director of Olfactory Absence.
