The Lab: Recent Research

How CADR, airflow, sealing, filter condition, and room size determine a HEPA purifier’s real-world performance.

A clear comparison of five durable outdoor air monitors focused on pollutants, weather resistance, power, data storage, and maintenance.

Explains how ozone oxidizes odors and microbes, its limits, safety steps, and why it’s only for vacant-space, controlled treatments.

Higher indoor humidity often boosts ozone’s surface virus kill rate, but dose, surface type, and safety monitoring determine real results.

Validate ozone dose, control worker exposure, and keep records to meet FDA, EPA, and OSHA ozone requirements.

Remove stubborn car odors: clean, dry, fix the source, then use ozone safely in an unoccupied, ventilated vehicle.
