Ozone generators like Prozone convert oxygen into ozone to oxidize certain compounds. They can reduce some odors but do not remove particles or carbon monoxide and can create harmful byproducts. Public-health organizations caution against using ozone generators in occupied spaces. For most homes, HEPA filtration and activated carbon are safer, more effective choices.

What a Prozone-style purifier claims to do

Prozone-style devices are ozone generators: they convert ordinary oxygen (O2) into ozone (O3), a reactive gas that can oxidize some airborne contaminants and odors. Older marketing for Prozone models describes creating ozone with ultraviolet light and sending it into the room to react with pollutants and odors.

How ozone reacts with pollutants

Ozone reacts chemically with some volatile organic compounds (VOCs), odor molecules, and certain microorganisms. Those reactions can reduce some odors and break down certain contaminants. However, ozone is not a universal "destroyer" of all indoor pollution. It does not reliably remove particles (dust, pollen) the way a HEPA filter does, and it does not remove carbon monoxide.

Safety and health considerations

Public health agencies caution against using ozone generators in occupied spaces. Ozone is a lung irritant and can worsen asthma, bronchitis, and other respiratory conditions. Ozone also reacts with indoor chemicals to form secondary pollutants (for example, formaldehyde and ultrafine particles) that may be harmful.

For these reasons, the Environmental Protection Agency and major respiratory-health organizations do not recommend using ozone generators as the primary means to clean indoor air.

Practical guidance for anyone using an ozone device

  • Prefer HEPA filtration plus activated carbon for most homes. Those systems remove particles, capture many odor-causing molecules, and do not produce ozone.
  • If you use a Prozone-style ozone generator: run it only in unoccupied spaces following the manufacturer's instructions, allow adequate time for ventilation before re-entry, and avoid continuous operation around people or pets.
  • Do not assume oxidation leaves only harmless "ash"; reactions can produce residues and secondary gases that need to be cleaned or ventilated.

Performance and device claims to check

Older Prozone materials describe a patented UV-based process and very low energy use (for example, comparing to a 50 W bulb) and recommend placing the unit high in a room for best spread. Those specific claims vary by model and age; verify them against current manufacturer specifications before purchase or use.

Better options for common problems

  • Allergies and particles: true HEPA air cleaners.
  • Odors and many VOCs: activated-carbon filters.
  • Mold or persistent water damage: fix the moisture source and consult remediation professionals.
If you are considering an ozone device for a specific problem (severe odor, smoke, or a health concern), weigh the limited benefits against the documented health risks and consult trusted indoor-air guidance from public health agencies.
  1. Verify whether modern Prozone models specifically use a patented two-UV-light ozone generation process and cite the patent or manufacturer specification. [[CHECK]]
  2. Confirm the manufacturer's stated energy use compared to a 50-watt bulb for the specific Prozone model being considered. [[CHECK]]
  3. Confirm any model-specific placement recommendation (for example, 6 feet above the floor) in current Prozone user manuals. [[CHECK]]

FAQs about Prozone Air Purifier

Is it safe to run a Prozone (ozone) purifier in an occupied room?
No. Health agencies advise against using ozone generators in occupied spaces because ozone irritates the lungs and can worsen respiratory conditions. If you run one, do so only in unoccupied rooms and ventilate thoroughly before re-entry.
Will ozone get rid of dust, pollen, and pet dander?
No. Ozone does not remove particles. Use a true HEPA filter to capture dust, pollen, pet dander, and other particulates.
Can ozone remove cigarette smoke and odors?
Ozone can oxidize some odor molecules and may reduce certain smells, but it can also form secondary pollutants. Activated carbon filters are a safer way to reduce many odors.
Does ozone eliminate viruses and mold?
Ozone can inactivate some microbes in laboratory conditions at high concentrations, but those concentrations are often unsafe for people. For mold, addressing moisture and remediation is the correct approach.
How should I choose an air cleaner instead?
For most indoor air issues choose a certified HEPA air cleaner for particles plus activated carbon for odors/VOCs. Increase ventilation and remove pollution sources when possible.
