I got the OADE20 dehumidifier was a warranty replacement for a ODE20 that was suffering from an intermittent glitch that corrupted the LCD display.
The newer model appears to work more efficiently and remove more water from the air. (It's used during Winter to reduce the moisture levels in the house and reduce wet windows on cold mornings.) The OADE20 has an Ioniser/ Titanium Dioxide button that is supposed to purify the air. I suffer from hay-fever/ sinus issues and have noticed that when that function is activated it does seem to help redu...ce my blocked sinus and hay-fever issues. Quote: "The Ioniser/Titanium dioxide button (16) is used to help clean the air. Running the Air Ioniser function produces negatively charged ions which are released into the air, attracting airborne particles (including bacteria) and removing it from the air. Titanium dioxide, when placed under a UV light, is a photocatalyst, which gives it sterilising and deodorising properties. Press the button once to turn on both functions (Ioniser/Titanium dioxide indicator (6) turns on). Press a second time to turn the functions off."
