Are you concerned about the air quality in your home? If so, you’re not alone. Many people are realizing the importance of clean air and are investing in air purifiers, such as the Air Doctor. One crucial aspect of maintaining an effective air purifier is regularly replacing the filters. This step-by-step guide will walk you through replacing filters in your Air Doctor cleaner, ensuring you and your loved ones can breathe fresh, clean air.

Removing The Filter Cover

First, you’ll need to remove the filter cover from your Air Doctor purifier. This cover is usually located on the back or side of the cleaner. Carefully inspect the purifier to locate the filter cover. Once found, follow these simple steps:

  1. Unplug the purifier from the power source to ensure your safety.
  2. Gently remove the filter cover by sliding it off or unhinging it, depending on the design of your Air Doctor purifier.
  3. Set the filter cover aside in a safe place that won’t get damaged or lost.

Taking Off The Plastic Covering From The New Filter(S)

Now that you have successfully removed the filter cover, it’s time to prepare your new filter(s) for installation. Most filters come with a protective plastic covering that needs to be removed before use. Here’s what you need to do:

  1. Carefully take the new filter(s) out of their packaging.
  2. Locate any plastic covering on the filter(s) and peel it off completely.
  3. Ensure no remnants of the plastic covering are left on the filter(s) before proceeding to the next steps.


Removing The Old Filter

With the new filter(s) ready, it’s time to remove the old filter from your Air Doctor purifier. Follow these instructions to ensure a smooth and efficient process:

  1. Look for an easy-to-grip white tab on the filter. This tab is usually located on the top or side of the filter.
  2. Hold the white tab firmly and pull it in the direction indicated on the tab. This action should release the old filter from its position.
  3. Set the old filter aside or dispose of it properly, following the manufacturer’s instructions.

Inserting The New Filter(s)

Now that you’ve successfully removed the old filter, it’s time to insert the new filter(s) into your Air Doctor purifier. Follow these steps to ensure proper installation:

  1. Locate the arrows on top of each filter. These arrows indicate the correct direction for insertion.
  2. Start by inserting the UltraHEPA Filter first. Align the arrows on the filter with the corresponding arrows or guides inside the purifier.
  3. Once the UltraHEPA Filter is securely in place, move on to the Carbon/Gas Trap/VOC Filter. Again, align the arrows on the filter with the corresponding arrows or guides inside the purifier.
  4. Ensure that both filters are inserted correctly and securely. Improper installation can affect the overall efficiency of your Air Doctor purifier.

Turning Off/Resetting The Change Filter Alert

Congratulations! You have successfully replaced the filters in your Air Doctor purifier. It’s time to turn off or reset the Change Filter alert to prevent false alarms. Follow these instructions:

  1. Locate the Auto and Dim buttons on your Air Doctor purifier. These buttons are usually located on the front panel.
  2. Press and hold the Auto and Dim buttons simultaneously for a few seconds.
  3. The alert light(s) on your Air Doctor purifier will flash three times and then turn off, indicating that the Change Filter alert has been reset.
  4. Your Air Doctor purifier is ready to continue providing clean air for your home.


Regularly replacing the filters in your Air Doctor purifier is essential for maintaining optimal air quality in your home. Following the step-by-step guide in this article, you can quickly and effectively replace the filters, ensuring that you and your loved ones can breathe fresh, clean air. Refer to the manufacturer’s instructions for specific details regarding your Air Doctor purifier model. 

It is generally recommended to replace the filters in your Air Doctor purifier every 6 to 12 months, depending on usage and air quality. However, if you notice a decrease in air flow or a drop in air quality, it may be necessary to replace the filters sooner. By staying on top of filter replacements, you can help prolong the life of your purifier and ensure that it continues to remove pollutants and allergens from the air effectively. Additionally, regularly clean the purifier’s exterior to prevent dust and debris from accumulating and affecting its performance. These simple maintenance steps will help you and your family enjoy cleaner, healthier air in your home.


Q1. How often should I replace the filters in my Air Doctor purifier? Answer: It is important to regularly replace the filters in your Air Doctor purifier to ensure maximum efficiency and effectiveness. The recommended time frame for replacing the filters is approximately every 6 to 12 months, depending on the usage and surrounding air conditions. However, keeping an eye on the filter indicator light, which will signal when the filters need to be changed, is also essential. Following the manufacturer’s instructions for proper maintenance and filter replacement is necessary to ensure clean and healthy air in your home or office. Neglecting to replace the filters can decrease performance and potentially result in harmful pollutants recirculating the air. Therefore, staying on top of filter replacements is best to ensure air quality in your space.

Q2. Can I reuse the old filters if they still look clean? Answer: It is not recommended to reuse old filters, even if they still appear clean. While they may not have visible dirt or debris, filters can become clogged with microscopic particles that can impact their effectiveness in filtering out pollutants and impurities. Additionally, filters can develop cracks or tears that may not be visible over time, allowing contaminants to bypass the filter and enter your air or water supply. Replacing filters according to the manufacturer’s recommendations is best to ensure clean and safe air or water.

Q3. Where can I purchase replacement filters for my Air Doctor purifier? Answer: Multiple options for purchasing replacement filters for your Air Doctor purifier are available. Firstly, you can visit the official website of Air Doctor and browse through their selection of replacement filters. They offer a variety of options to choose from, making it easy to find the right filter for your specific purifier model. Another option is to visit online retailers such as Amazon or Walmart, where you can find a wide range of replacement filters for the Air Doctor purifier at competitive prices. You can also check with local home goods stores or appliance stores, which may carry replacement filters for Air Doctor purifiers. By exploring these options, you can easily find and purchase the correct replacement filters to ensure your Air Doctor purifier functions effectively and provides clean air for your home. Also, you will find filters on Amazon.

Q4. Is it necessary to turn off the cleaner before replacing the filters? Answer: Turning off your purifier before replacing the filters is highly recommended. This is important to ensure the users’ and the purifiers’ safety. When the purifier is turned off, it prevents potential electrocution or other accidents. Turning off the cleaner also allows the filters to cool down, making them easier to handle and replace. Furthermore, leaving the purifier on while replacing the filters may cause the filters to be clogged or damaged, reducing their effectiveness and potentially harming the air quality. Thus, it is always better to err on caution and turn off the purifier before replacing the filters.

Q5. How can I tell if the filters in my Air Doctor purifier need to be replaced? Answer: To maintain clean and quality air in your home, it is essential to regularly check and replace the filters in your Air Doctor purifier. One way to tell if the filters need to be replaced is by looking at their color. If the filters appear dark or discolored, it is a sign that they have reached their maximum capacity and should be replaced. Another way to tell is by checking the airflow. If the airflow seems weaker than usual, it could be due to clogged filters, indicating that they need to be replaced. Additionally, most Air Doctor purifiers come with a filter replacement indicator, which will light up when it is time to change the filters. Following the manufacturer’s recommendations for replacing filters is essential to ensure that your purifier continues to clean your home’s air effectively.
