Airthereal B50 Mini Ozone Generator Air Purifier- Removes Odors and Sterilizes Air in Small Spaces Up To 320 Sq Ft - Plug in Mini Air Ionizer, Adjustable Ozone Output of 10-50 mg/h

This Ozone generator works at removing bad smells!! We have a wine cellar that had a permanent "perfume" like smell which was very off putting. We are not the original homeowners so we could not figure out where the smell was coming from, and it would not go away even after leaving the cellar door open for days. We got this ozone generator and left it running at the smaller setting for about 2 weeks. The smell is now gone for good!!!

Great at cleaning the air where my cats litter box is. Keeps dust down. Each one lasts about a year.

I wanted to update my reviewe as i was contacted by the seller after i flagged my broken device and i was delivered a replacement device. The service was very quick and efficient. I recommend this seller. Device broke few months after purchase and now makes ungodly sounds. It initially did good job eliminating smok odor and one could feel the ozone scent but it quickly turned into a noise maker.

I purchased two of these and they are able to pump out tons of O3. I have had one set up on a timer to give my basement an occasional spritz. It freshens up the entire floor. I wouldn't recommend it for constant use. It generates far too much ozone. It probably wouldn't be healthy. It is amazing for occasional use, though. It would work great to deodorize a room. Even a large one. I did have one unit burn out after a few months. I think moisture got to it and the dielectric broke down. It was just sending an arc right through rather then generating a corona.

These are great little ozone purifiers. I have them in several rooms and one of the closets. They really work!

WORD OF WARNING: All ozone generators are meant to only be used in unoccupied spaces. Don't let people and pets enter the area until 30 minutes after ozone generation ends. Not available for sale in California; EPA Est. No. : 99066-CHN-1. Manufacturers and vendors of ozone devices often use misleading terms to describe ozone. Terms such as "energized oxygen" or "pure air" suggest that ozone is a healthy kind of oxygen. Ozone is a toxic gas with vastly different chemical and toxicological properties from oxygen. Several federal agencies have established health standards or recommendations to limit human exposure to ozone. The phrase "good up high - bad nearby" has been used by the U.S. Environmental Protection Agency (EPA) to make the distinction between ozone in the upper and lower atmosphere. Ozone in the upper atmosphere--referred to as "stratospheric ozone"--helps filter out damaging ultraviolet radiation from the sun. Though ozone in the stratosphere is protective, ozone in the atmosphere - which is the air we breathe - can be harmful to the respiratory system. Harmful levels of ozone can be produced by the interaction of sunlight with certain chemicals emitted to the environment (e.g., automobile emissions and chemical emissions of industrial plants). These harmful concentrations of ozone in the atmosphere are often accompanied by high concentrations of other pollutants, including nitrogen dioxide, fine particles and hydrocarbons. Whether pure or mixed with other chemicals, ozone can be harmful to health. for many of the chemicals with which ozone does readily react, the reaction can form a variety of harmful or irritating by-products (Weschler et al., 1992a, 1992b, 1996; Zhang and Lioy, 1994). For example, in a laboratory experiment that mixed ozone with chemicals from new carpet, ozone reduced many of these chemicals, including those which can produce new carpet odor. However, in the process, the reaction produced a variety of aldehydes, and the total concentration of organic chemicals in the air increased rather than decreased after the introduction of ozone (Weschler, et. al., 1992b). In addition to aldehydes, ozone may also increase indoor concentrations of formic acid (Zhang and Lioy, 1994), both of which can irritate the lungs if produced in sufficient amounts. Some of the potential by-products produced by ozone’s reactions with other chemicals are themselves very reactive and capable of producing irritating and corrosive by-products (Weschler and Shields, 1996, 1997a, 1997b). Given the complexity of the chemical reactions that occur, additional research is needed to more completely understand the complex interactions of indoor chemicals in the presence of ozone. ozone does not remove particles (e.g., dust and pollen) from the air, including the particles that cause most allergies. However, some ozone generators are manufactured with an "ion generator" or "ionizer" in the same unit. An ionizer is a device that disperses negatively (and/or positively) charged ions into the air. These ions attach to particles in the air giving them a negative (or positive) charge so that the particles may attach to nearby surfaces such as walls or furniture, or attach to one another and settle out of the air. In recent experiments, ionizers were found to be less effective in removing particles of dust, tobacco smoke, pollen or fungal spores than either high efficiency particle filters or electrostatic precipitators. (Shaughnessy et al., 1994; Pierce, et al., 1996). However, it is apparent from other experiments that the effectiveness of particle air cleaners, including electrostatic precipitators, ion generators, or pleated filters varies widely (U.S. EPA, 1995). Ozone has been extensively used for water purification, but ozone chemistry in water is not the same as ozone chemistry in air. High concentrations of ozone in air, when people are not present, are sometimes used to help decontaminate an unoccupied space from certain chemical or biological contaminants or odors (e.g., fire restoration). However, little is known about the chemical by-products left behind by these processes (Dunston and Spivak, 1997). While high concentrations of ozone in air may sometimes be appropriate in these circumstances, conditions should be sufficiently controlled to insure that no person or pet becomes exposed. Ozone can adversely affect indoor plants, and damage materials such as rubber, electrical wire coatings and fabrics and art work containing susceptible dyes and pigments (U.S. EPA, 1996a). When inhaled, ozone can damage the lungs. Relatively low amounts of ozone can cause chest pain, coughing, shortness of breath and, throat irritation. It may also worsen chronic respiratory diseases such as asthma as well as compromise the ability of the body to fight respiratory infections.

Lasted for about 6 months running for 15 minutes per day. It worked surprisingly well for its size while it lasted, but I think you'll be lucky to get a year out of it.

This really does dispel bad odors. The room will have a weird smell after using but that dissipates pretty quickly after opening doors an windows for a few minutes.
