Ozone Generators for Grow Room Odor Control
Ozone generators produce ozone (O3) -- a highly reactive form of oxygen that oxidizes and neutralizes organic odor compounds, VOCs, and some pathogens on contact. In grow room applications, ozone generators are used for odor control in exhaust air streams and for surface sterilization between crop cycles. XPOWER produces the primary inline ozone generator products at Hydrobuilder, including air mover units with integrated ozone generation (M-25, M-27) and programmable sanitizing systems that combine HEPA filtration with ozone for comprehensive air treatment. DL Wholesale provides UV-based ozone generation units and portable UV wands for surface treatment applications.
Inline vs. Room-Type Ozone Units
Inline ozone generators are installed in the exhaust duct between the grow room and the exterior -- ozone is injected into the exhaust stream where it oxidizes odor compounds before the air exits the facility. The ozone breaks down before reaching the exterior, and residual ozone in the duct degrades to oxygen quickly. Room-type ozone generators or air mover units (XPOWER M series) circulate air through the generator in the grow space itself -- producing higher localized ozone concentrations. Room-type ozone at elevated concentrations requires vacating the space during operation; residual ozone should be allowed to dissipate before re-entry. The XPOWER Olympus PLUS and Everest PLUS programmable sanitizing systems combine HEPA air purification with ozone generation and digital timer control for managed, cycle-based sanitization protocols.
Safety and Usage
OSHA regulates ozone exposure in occupied workplaces. At concentrations effective for odor control and surface sanitization, ozone is harmful to respiratory health -- never operate high-output ozone generators in occupied spaces. Inline duct applications that inject ozone downstream of occupied areas are the safest operational format. Browse carbon filters and odor control as a primary odor management approach.

Ozone Generators FAQ
How does an ozone generator control odors in a grow room?
Ozone (O3) is an unstable molecule that readily oxidizes organic compounds on contact -- the extra oxygen atom in ozone attaches to and breaks apart the molecular structure of VOCs and odor compounds, converting them to simpler, odorless compounds (water, CO2, and basic organic molecules). When exhaust air from a grow room passes through an ozone-enriched zone in a duct, the ozone reacts with odor compounds in the airstream and neutralizes them before the air exits the facility. The ozone itself breaks down to normal O2 oxygen within minutes to hours, leaving no residue. This makes inline ozone injection a highly effective final-stage odor treatment for facilities where carbon filtration alone is insufficient.
Is it safe to use an ozone generator in an occupied grow room?
Ozone at high concentrations is a respiratory irritant and is regulated as a workplace hazard. OSHA sets a permissible exposure limit of 0.1 ppm for 8-hour occupational exposure. High-output room-type ozone generators designed for sanitization operate at concentrations far above this limit -- these units require the space to be vacated during operation and adequate ventilation time before re-entry. Inline duct ozone injection (where ozone is added to the exhaust stream after the air has left the occupied zone) does not expose workers to elevated ozone concentrations in the work area and is the operationally safe format for grow facilities with regular human presence.
What ozone output do I need for my grow room?
Inline duct ozone generators are sized by their ozone output (mg/hr) and the exhaust flow rate of the ventilation system. A general guideline for inline odor control: 200-500 mg/hr for 200-400 CFM exhaust flow; 500-1000 mg/hr for 400-800 CFM. The goal is adequate ozone concentration in the air stream for the contact time available in the duct run -- longer duct runs from ozone injection point to exterior allow more contact time and work with lower concentrations. For room sanitization applications, the XPOWER M-series units produce 5,000-10,000 mg/hr -- sized for timed sanitization of empty spaces rather than continuous occupied-space odor control.
