Review on 🌬️ OdorStop OS900/6G: Professional Grade Ozone Generator Ionizer - Deodorize and Purify Bathrooms, Bedrooms, Cars, RV's, Boats & More! by Amanda Turner

This product works as advertised. It produces ozone, and ozone has an odor. It has no way of showing the concentration of ozone in the air, so when using the product, it cannot say whether the room is safe after the product is turned off. We have used it in our basement and in a rented hotel room. I run the unit for 20-30 minutes at a time and then let the area sit for another 20-30 minutes before entering. But without the ability to measure ozone I can't tell if the area is safe.
