It was developed from the same advanced air purification technology used by the US Navy submarine fleet. Here's how it works. The permanent mesh prefilter traps larger particles as dirty air is drawn in from the room. The air then passes through the Truman cell's electrostatic curtain, which positively charges those tiny particles. The negatively charged collection plates then capture these particles like a powerful magnet. Next, VOC shield not only reduces tough household odors, it also reduces harmful chemical fumes and gases. Then the oxygenator converts ozone into pure oxygen. And finally, the air revitalizer freshens the air before it's sent back into the room. Now to learn a little more about the Oreck Air Purifier's key features, state tuned. The Oreck Professional Air Purifier does more than just look good. Let's take a closer look at some of its features. Yep, that's the one that turns the air purifier on. This button has three settings, depending on what your needs are, and each is indicated in the panel above the button. High for accelerated cleaning like when you accidentally burn dinner and that house is full of smoke an unpleasant odors. Medium for normal everyday use. And silence for silence technology, the quietest setting. Regardless of your power setting, you'll find the Oreck Air Purifier remarkably easy on your ears. But you have to move the air to clean it. So if you hear the fan running, you know the unit is filtering your air. When an Oreck air purifier is running in any mode, occasionally you'll hear sharp snapped or arcing sound.

If you appreciate the way the air smells and feels fresh after a thunderstorm, you want to keep the air revitalizer button in the On position, and enjoy the negative ions emitted. When the Truman cell is ready for a cleaning, this light comes on. It resets automatically when the collector cell has been removed for cleaning. The optional odor absorber is usually good for 12 months, so it's very helpful to have a light go on to remind you that it needs changing, that way you can continue to reduce household orders and volatile organic compounds. That's right, the Oreck XL Professional Air Purifier even has a night light installed. It's up to you to use it or not.
