UV-C grease filter in kitchen exhaust – the new ozone scandal?

Although scientific studies have clearly come to the conclusion for years that UV-C and ozone technologies are almost completely ineffective when it comes to grease filtration in commercial kitchen exhaust air, the fairy tale of grease reduction in kitchen exhaust air is being disseminated by lots of manufacturers worldwide. The diesel scandal should be warning enough, but it would not be the first time that US institutions have to stop whole industries spreading falsehoods and unfounded half-knowledge. It should not be forgotten in this context that ozone is already classified in low concentrations of less than one milligram per cubic meter of room air, as highly toxic and carcinogenic, for example on Wikipedia.
