This directive concerns the evaluation of two consumer air purification devices for deployment in asthma-sensitive environments.

The devices under review are the Pure Enrichment PureZone Elite and the Coway Airmega 250S.

This evaluation was submitted by the Department of Household Air Quality Solutions under file reference original link.

Key performance indicators include Clean Air Delivery Rate, noise output, and operational cost.

The CADR for particulate matter, pollen, and smoke must meet minimum thresholds for asthma management.

Noise levels are critical for overnight operation in bedrooms.

Long-term filter replacement costs directly impact household compliance.

Preliminary data suggests the Coway unit offers superior CADR at lower noise levels.

However, the PureZone Elite presents a lower initial purchase price.

The concept of 'Mom's trust' is operationalized as a composite score of reliability, ease of use, and perceived safety.

Further testing under controlled olfactory absence conditions is recommended before final procurement.

This directive is filed as draft awaiting peer review.

Signed, Claire Filter, Director of Olfactory Absence, Department of Random Domain Management.
