Air Purifier Troubleshooting: How to Fix Common Problems

Troubleshooting air purifier

Having an air purifier in your home is an investment in ensuring the air you and your family breathe is as clean and healthy as possible. The Appliance Guys is a great place to find an air purifier that suits your needs.  But, as with any appliance, things can go wrong. When your air purifier is malfunctioning, don’t panic – you can usually troubleshoot the problem so it runs effectively again.

Here are a few tips for troubleshooting your air purifier:

Troubleshooting Your Air Purifier When Something Goes Wrong

Failure to Turn on

If your air purifier won’t turn on, the first step is to check if it’s properly plugged in. If the cord is hooked up, but the unit still won’t start, check the outlet. Make sure it’s functioning properly and that the plug is securely connected. One last thing to check if your purifier is still not responding is the power rating if it’s too low or too high, it won’t work correctly. Always check the power rating mentioned in the product details and manual of the air purifier. An inaccurate power rating can damage your appliance, so you want to make sure it’s the right fit for the outlet.

Unresponsive Control

Most air purifiers come with control systems that are either push buttons or touch buttons. These let you control the speed and settings of your device. If this system is unresponsive or not working correctly, it can affect how well the air purifier works. Check if the buttons are clean and free from any dust or debris. If there’s too much dirt, it can interfere with the functioning of the control system. You should also check the filter cover; if it is improperly placed, remove it and place it back as outlined in your appliance’s user manual. If you notice any malfunction or defect in the controls, don’t hesitate to contact the manufacturer’s support team and let them know about your issue. They will be able to assist you with troubleshooting and provide help if needed.


One of the most common issues with air purifiers is that they sometimes make unwanted noises. This can be due to an improperly installed filter or a faulty motor. If you notice any strange sounds coming from your air purifier, turn it off immediately and find the source of the problem. Check the filter and make sure it fits securely in the cover. If it is too dirty or damaged, replace the filter with a new one. You can do this yourself by following the instructions in the user manual.  In case of a faulty motor, contact an expert.

Poor Performance

Your air purifier may be running perfectly but not performing as expected. This could be due to poor air quality, dust-clogged filters, physical items blocking the purified air from circulating throughout the room and incorrect placement of your purifier. To solve this issue, make sure the room is well-ventilated before running the purifier. Also, check that there is nothing blocking the air intake and outlet of the unit. Also, remember that air purifiers are not designed for large, open spaces, so make sure it’s the right size for your room.

Strange Smell

If your air purifier has started to emit a strange or unpleasant smell, the source of this odor may be smoke or other odors coming from inside or outside the house. To get rid of this smell, try ventilation: open the windows and doors for an hour to let fresh air in.  If this doesn’t help, install an exhaust or vent in the kitchen to eliminate any smell arising from cooking. Make sure to replace the air filter in your purifier periodically, as some filters, such as activated carbon, can create a strange smell. Find out how to remove junk from your home.

Improper Airflow

Proper airflow is essential for air purifiers to work.  If you observe that the air is not circulating well, first check the fan speed. Adjust it to a higher setting or switch it to auto mode. Check the plug and make sure it’s inserted securely into the outlet. If you’re still having issues, try cleaning the air vent and the filter cover to get rid of any dust or debris. In some cases, you may need to replace the air filter with a new one. If nothing works, contact the manufacturer’s customer service for assistance.

No matter how much you clean, sometimes your home doesn’t feel fresh. If you have an air purifier, it may be time to troubleshoot when something goes wrong. Check to see if any of these solutions match your problem. Don’t hesitate to contact the manufacturer for additional support or take your air purifier in for repair if needed. By keeping up with the maintenance of your device, you can ensure many years of easy breathing in your home.
