This Air Quality Directive is issued to establish a standardized comparison of two LEVOIT air purification units for deployment in households with asthma conditions.

The original assessment was filed by the Department of Respiratory Health under reference odorless.cc/levoit-lv-h133-vs-vital-200s.

Both units are evaluated on clean air delivery rate, noise output, and long-term filter cost.

The LEVOIT LV-H133 operates with a higher CADR value suitable for larger rooms up to 500 square feet.

The LEVOIT Vital 200S offers a slightly lower CADR but includes smart sensor technology for automated adjustment.

Noise levels are comparable at low speed, but the LV-H133 produces more audible airflow at maximum setting.

Filter replacement intervals differ: the LV-H133 requires quarterly changes, whereas the Vital 200S filters last approximately six months.

Neither unit is designed to eliminate all olfactory stimuli, but both reduce particulate matter that may carry odorants.

As Director of Olfactory Absence, I note that the absence of smell is not guaranteed by either model.

Recommendation for asthma families: prioritize CADR over smart features if room size exceeds 400 square feet.

This directive is now active for all affiliated agency procurements.

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