Whether you believe it or not, the air quality inside the home is usually heavily polluted Trusted Source Indoor Air Quality - EPA “Indoor air quality” refers to the quality of the air in a home, school, office, or other building environment. The potential impact of indoor air quality on human health nationally can be noteworthy for several reasons . This pollution is the result of different things. Some of the things that can cause this pollution include chemical fumes, VOCs, mold, dust, pollen, smoke from cooking, and so on. Oreck is an excellent brand that makes air purifiers. One of the best air purifiers from the brand is the Oreck XL air purifier. You must maintain this appliance, and in this post, we will show you how to clean Oreck XL air purifier.

This air purifier from Oreck comes with several nice features, including four modes to clean the air. These include the silence, medium, high, and turbo modes. This excellent unit uses special pre-filter and other filters to keep the air clean of any contaminants. Cleaning the filters is relatively easy and straightforward as we will show you in this review.

Filters in the Oreck XL Air Purifier

As an air purifier, filters form an essential part of the Oreck XL.

It comes with 5 filtration methods. A consideration of these filters will help you to better understand the steps that are to be taken in cleaning the purifier.


First filter is the pre-filter. This filter is a very important part of the device for several reasons. For one, it helps with improving the cleanness of the air. Due to the filter, large contaminants like debris, dust, and dander are kept out of the air.

The pre-filter is also important because it will prevent these large contaminants from reaching the other filters in the device, thus freeing them up to do their job effectively and prevent any clogging. The pre-filter found on this model will last throughout the lifespan of the appliance. One of the best options we have found in reviews is the Oreck Airvantage Plus due to the durability and excellent filtration ability.

Truman Cells

The second line of defense are the Truman cells. These are ionizing plates that create ions. The negative and positive ions are created here and work to help reduce the pollutants in the air. The ions attach to the pollutants in the air, making them heavier which will drag them to the ground.


Next is the oxygenator, which as the name implies, has something to do with oxygen. Since the Truman cells create ions, the oxygenator works to convert the ions and ozone into oxygen. It is important because it ensures your safety.

UV Light

UV radiation is a powerful means of killing any contaminants. In this model, the technology works to kill off any bacteria or harmful microorganisms that lurk in the air. It is perfectly safe for humans while deadly to contaminating organisms.

Activated Carbon Filter

How to Clean Oreck XL Air Purifier?

If you are looking to get rid of odors in the air, then this filter is what is needed, and it is excellent that it has been added to the unit. It will work to remove the smells and fumes in the air. It will also work to eliminate other smaller pollutants.

As is evident, all of these filters combine to form a purifier that will help you to remove contaminants. It results in an air purifier that is perfectly capable of allowing you to enjoy good quality air to breathe all day long.

How do I clean an Oreck XL air purifier?

Now that we have considered the important parts of the Oreck XL purifier, let us now see how you can clean the appliance.

Unplug the Purifier

The first thing that you must do before you start cleaning the purifier is to unplug it. Since you will open it up, you should unplug it. This will help to eliminate the possibility of getting electrocuted by the appliance.

Remove and clean the Pre-filter

The pre-filter of the Oreck XL will last for as long as you use the appliances, as long as you are using it correctly. One way to maintain it is to clean it. First, remove the pre-filter.

How to remove the pre-filter depends on the model. There are two models; one is the tower model while the other is wall-mounted. The Oreck WK15500B is one of the best tower models that we have found in our research according to the numerous customers reviews. For the tower model, hold the edge of the filter door on the front panel of the unit, press the button and pull it outward gently.

The pre-filter is identified as the small rectangle that slides out of the appliance.

To clean the pre-filter, wash it in warm, soapy water. Before washing it, though, soak it in the water for up to two hours. Once washed, rinse it off. Then wait until it is completely dry.

Clean the Cell

First, disengage the Truman cell collector. You remove it the same way that you remove the pre-filter. However, it will need to be unscrewed.

Once removed, place it in warm, soapy water for at least two hours. Take care that you don’t scrub the collector with anything. Just rinse it in water to remove any dirt on it. After rinsing, dry it off completely.

Clean the Air Direction Grills

These are similar to air vents found in vehicles. As these are right in the way of the incoming air, they might be dusty. It is therefore important that you clean these regularly.

If you have purchased an original model, it should come with a small brush under the top cover. You will use the brush to remove the dirt and debris on the air grills.

Clean the Oxygenator

This important part of the appliance should also be cleaned. Due to what it does, it lies on the rear of the model.

To clean it, slide off the top cover. You will identify this oxygenator as a flat area inside the appliance. You cannot remove it, so you can vacuum it gently. Never use liquids to wash the oxygenator.

After you do this, return the cover.

Odor Absorber

The odor absorber lies inside the unit. So, you have to open the front control panel and press the button that is labeled Fragrance Cartridge. This will slide out the cartridge and you can replace it. For the odor absorber, find it above the collector cell. Once identified, slide it down and replace it with a new one.


After all the parts have been washed and thoroughly dried, then you should put them back into the appliance. Close the grill and test the device.

Final Thought

From our research, the Oreck Xl is one of the best air purifiers from the manufacturer. Many users have remarked on the impressive features and good air filtration. It employs a technology that is usually found in more advanced HVAC systems. With the combination of pre-filter and Truman cell collector, you have a unit that will keep contaminants out of the air. The pre-filter is permanent and can be cleaned for re-use.

Follow the steps we have listed on how to clean Oreck XL air purifier, and you can rest assured of continued good performance.
