Oreck Air uses a five-stage purification process to clean the air. The diagram below illustrates the various purification stages.

The five-stage purification process which Oreck uses effectively filters 95% of particles as small as 0.1 microns. First, a pre-filter captures large particles such as hair and lint. Electricity is used to positively charge smaller particles, which are then locked in by the alternately charged plates of the collector cell. An optional odour absorber uses activated charcoal to absorb common household odours, and finally, an Air Revitalizer emits negative ions to freshen stale air. No other purifier uses this powerful combination of technology.

The Oreck Air does not require any replaceable filters. It uses a permanent pre-filter to filter larger particles and hairs; the pre-filter can be rinsed off and re-used continually.

In addition to air purification, the Oreck Air provides the additional benefit of odour removal with its charcoal odour absorber.  The charcoal odour absorber is optional, and odour absorption effectiveness will gradually deteriorate over time unless the charcoal odour absorber is replaced. The Oreck Air will continue to remove harmful airborne particles with its permanent electronic collector cell even if you choose not to use the optional charcoal odour absorber.

IMPORTANT: DO NOT wash the charcoal odor absorber. Replace, if necessary.

The Air Revitalizer is the fifth stage of the Oreck 5-stage air purification process; it releases negative ions to revitalize the air.  The Air Revitalizer can be turned on or off on the Oreck Air. Turning the Air Revitalizer on provides a pleasant, clean smell, but does not impact the air purifier’s cleaning efficiency.

No, the Oreck Air is not an ozone generator because it does not rely on ozone as part of the cleaning process. Ozone is a natural by-product of many electrical appliances.

The Oreck Air's Air Revitalizer does produce very low levels of ozone, and can be turned on or off with a switch located on the front of the unit. Any ozone produced by the Air Revitalizer does not impact the Oreck Air’s cleaning efficiency. When the Air Revitalizer is on, the ozone produced by both the Air Revitalizer and the Oreck Air together is well under UL and FDA guidelines of 50 ppb (parts per billion).

Yes. As a large particle is captured in the collector cell, the Oreck Air may make a sparking or popping noise. Cleaning the collector cell may help. If your Oreck Air continues to make excessive popping noises, it may be damaged and should be returned.

The electronic collector cell cleans easily in detergent and water. The collector cell should be allowed to air dry before re-inserting. Oreck does not recommend the use of heated or compressed air as part of the drying process.

Oreck offers Assail-a-Cell® cleaner for particularly stubborn dirt and grime (such as tobacco tar); It is the fastest and easiest way to clean the collector cell because the high-action foaming cleanser liquefies dirt, tobacco, tar, and other residue.

Do not try to clean the collector cell by inserting a cloth, brush, or other device between the cell plates.  Inserting objects in the collector cell may damage the positive charging wires or collector cell plates.

How often you need to wash it depends on the environment. A good suggestion is to wash the cell after the initial four weeks of use and once every eight weeks thereafter, though you may find that a different cleaning schedule is better for you over time.

The red "Wash Cell" light is set off by a high amperage sensor. It is not necessary to wait for the red light before cleaning the collector cell. Very dirty collector cells or arcing will set off the red "Wash Light" cell, but Oreck recommends cleaning the cell on a regular scheduled basis (typically every two months or as desired) before the light goes off.

Pure oxygen is a combustible gas, and you should take appropriate precautions when using electrical appliances such as the Oreck Air in the presence of an oxygen machine or tank. We suggest that you consult with your oxygen and medical equipment providers regarding the use of the Oreck Air in the presence of oxygen or other combustible gases.

You’ll find best results using the Oreck Air in an appropriately sized room—Oreck suggests not more than a 30’ by 30’ room, though this size may depend on the environment (pets, foot traffic, frequency of opening and closing doors to the outside).
Of course, no air purifier can clean through walls; an air purifier is designed to be room specific.

You will likely see a difference as quickly as the first few days of use, but you should definitely begin to see a difference in the first two weeks.

The collector cell cleans as effectively on the Silence setting as it does on the high setting, however the fan moves slower. As a result, the Oreck Air cleans as well on low as on high, but will clean the room more slowly as it circulates less air.
To maximize cleaning effectiveness, you may choose to set the purifier on high or medium while out of the house, and set the purifier on Silence when noise is a potential issue.

Yes, but you may be pleasantly surprised at how infrequently. Using the Oreck Air helps to protect home furnishings from damaging pollutants and will keep the house looking cleaner longer.
