Review on Mini Aer Humidifier Revitalizer Fragrance by Susan Oliver

We bought 2 of these at a house show about a year and a half ago to use in rooms where we had litter boxes. They worked great! But only for a short time. After about 3 months, one of them became very noisy. I contacted Triad and they replaced it under warranty and all I had to do was pay to send the bad one back. However, shortly after the 1-year warranty expired, both stopped producing ozone, which removes odors from the air. Which makes them literally useless. I really liked them but for the price they should last longer.
