What Is a Hydroxyl Generator and Is It Safe?

A hydroxyl generator uses ultraviolet light and moisture in the air to create hydroxyl radicals. These reactive molecules interact with odor-causing compounds, volatile organic compounds, and some microbes, breaking them down into harmless byproducts like carbon dioxide and water.

This process is similar to what happens naturally in the atmosphere. The technology is often used in water damage cleanup to address musty smells and lingering contaminants without the need for harsh chemicals or extensive ventilation.

These generators are useful after water damage, especially when drying out a home and dealing with persistent odors. They can be run in rooms while you are present, making them a practical option for ongoing cleanup.

You might use one in a basement, attic, or other affected area, but they are not a substitute for proper drying and removal of wet materials. They complement, rather than replace, thorough water damage cleanup.

• Use after removing standing water and wet items
• Run continuously for several days for good results
• Keep doors and windows slightly open for airflow
• Place on a flat, stable surface away from walls
• Do not point directly at people or pets

If you are dealing with significant water damage, consider contacting local water damage pros for an inspection. They can assess the extent of the issue and advise on drying, cleaning, and repairs.

For minor odor problems, you might rent or buy a hydroxyl generator yourself. For larger jobs, the pros often use these units as part of a broader cleanup process.

Policies vary, and your insurer decides what is covered.

• Inspect affected areas for hidden moisture
• Remove wet carpet, drywall, or insulation promptly
• Use fans and dehumidifiers to speed drying
• Check for mold growth on surfaces
• Keep records of any cleanup steps you take
