Step-by-Step Guide: Replacing Filters in the AirDoctor 5000


If you own an AirDoctor 5000 air purifier, you know how important it is to change the filters to keep the unit running efficiently and regularly. Replacing filters may seem daunting, but fear not – we’re here to guide you through it step by step. In this article, we will provide a detailed process for replacing the filters in your AirDoctor 5000. Following these simple instructions ensures that your air purifier continues providing clean and fresh air.

Step 1: Turn off and unplug the unit

Before starting the filter replacement process, turn off and unplug the AirDoctor 5000. This is a crucial safety step to avoid accidents or electric shocks while handling the unit.

Step 2: Pull the front cover towards you and remove it

To access the filters, start by pulling the front cover towards you. The front cover is held in place by a set of tabs that need to be released before removing the cover.

Step 3: Lift and pull the tabs on both sides to remove the filters

Once you have removed the front cover, you will see the filters inside the unit. To remove the filters, lift and pull the tabs on both sides simultaneously. This will loosen the filters and allow you to take them out.

Step 4: The Pre-filter is the first filter to be removed and the last filter to be installed

The first filter to be removed is the Pre-filter. This filter captures larger particles such as dust, pet hair, and lint. It is important to note that the Pre-filter is also the last filter to be installed when replacing the filters.

Step 5: Insert new UltraHEPA® and Carbon/Gas Trap/VOC Filters

Now that you have removed the old filters, it’s time to insert the new ones. Start by inserting the UltraHEPA® filter, which captures 99.97% of particles as small as 0.3 microns. Make sure the filter is aligned correctly and securely in place.

Next, insert the Carbon/Gas Trap/VOC filter. This filter helps eliminate odors, chemicals, and VOCs (volatile organic compounds) from the air. Like the UltraHEPA® filter, ensure the Carbon/Gas Trap/VOC filter is correctly positioned and firmly inserted.

Step 6: Insert the bottom of the inlet grill first, then snap the upper part of the front cover back into position

Once the new filters are in place, it’s time to reassemble the unit. Begin by inserting the bottom of the inlet grill first. Please make sure it is correctly aligned with the unit. Once the bottom part is securely in place, snap the upper part of the front cover back into position.

Step 7: Make sure the bottom hooks of the front cover are correctly in place before closing it

Before closing the front cover completely, double-check that the bottom hooks are appropriately aligned and in place. Closing the cover without ensuring the hooks are secure may result in an improper seal, affecting the air purifier’s performance.

Step 8: To reset the Change Filter alert, press and hold the Auto and Dim buttons for 5 seconds until the alert light(s) turn off

After replacing the filters, reset the Change Filter alert on your AirDoctor 5000. To do this, press and hold the Auto and Dim buttons simultaneously for 5 seconds or until the alert light(s) turn off. This step will ensure that the unit accurately monitors filter replacement in the future.


Replacing the filters in your AirDoctor 5000 is a simple process you can easily do at home. By following the step-by-step guide we provided, you can maintain the efficiency of your air purifier and continue enjoying clean and fresh air in your living space.

Turn off and unplug the unit, remove the front cover, replace the filters correctly, and reset the Change Filter alert. For more information and to purchase replacement filters, visit the Official AirDoctor site.
