ozone generator, solar powered vents, 20yrs liveaboard never a single spec of mold
No they don't disagree with me if you use it properly. Our Heavenfresh 300C air purifier with HEPA filter, UV filter, charcoal filter, ion generator and ozone generator ran 24hrs/day except for the ozone which was only engaged while not on board.The US EPA disagrees with you, as does every other health authority, it seems.
Table 1. Ozone Heath Effects and Standards
Health Effects Risk Factors Health Standards*
Potential risk of experiencing:
Decreases in lung function
Aggravation of asthma
Throat irritation and cough
Chest pain and shortness of breath
Inflammation of lung tissue
Higher susceptibility to respiratory infection Factors expected to increase risk and severity of health effects are:
Increase in ozone air concentration
Greater duration of exposure for some health effects
Activities that raise the breathing rate (e.g., exercise)
Certain pre-existing lung diseases (e.g., asthma)
The Food and Drug Administration (FDA) requires ozone output of indoor medical devices to be no more than 0.05 ppm.
The Occupational Safety and Health Administration (OSHA) requires that workers not be exposed to an average concentration of more than 0.10 ppm for 8 hours.
The National Institute of Occupational Safety and Health (NIOSH) recommends an upper limit of 0.10 ppm, not to be exceeded at any time.
EPA's National Ambient Air Quality Standard for ozone is a maximum 8 hour average outdoor concentration of 0.08 ppm (see - the Clean Air Act - Title I | Clean Air Act | US EPA)
