Here we listed some common Honeywell Air purifier Troubleshooting: most common problems.
Problem 1:if it keeps turning off
This is a very common problem that Honeywell air purifier users face. When you turn it on, your purifier may turn off even if it is properly plugged in. There are some reasons for this. Let’s have a look at these reasons and their possible solutions.
The battery is too weak to run the purifier
A weak battery often causes this problem. If you have used your Honeywell air purifier for a long time, it may be time to change your battery. Remember to replace both batteries at once for optimal performance.
Solution: Replace the battery of your purifier. For this, you can call an electrician or a Honeywell service center.
Dust and molds are stuck into the filter.
If your air quality is poor, it’s not surprising if your Honeywell air purifier keeps turning off. Before you purchase a new battery, check and clean all filters. Filters will eventually clog up, especially in a place with moderate to high dust.
Solution: Clean the filters of Honeywell air purifiers. While cleaning your filters, take an opportunity to vacuum them as well.
The purifier is Overheated.
Many of us have accidentally put our air cleaners near a heat source, like a heater. If you have done so and your Honeywell air purifier keeps turning off, move it to a different location. A cool, dry place away from direct sunlight will help prevent overheating and ensure that your Honeywell air purifier stays on for as long as possible.
Problem 2: troubleshooting if Different colors of lights keep blinking
Different colors of lights indicate different things. Red and orange mean it needs to be cleaned, or something is wrong with your system; they are warning signs, not maintenance alerts.
Orange Light
The orange light indicates a dirty filter.
Solution: To clean it, unplug your unit and remove it from your home. Give it a good vacuuming, then replace it and plug in your unit to resume operation. If you don’t use your air purifier daily, consider leaving it plugged in so you can run a quick once-over with a vacuum before using it.
Red light:
The red light is on. Red light can indicate the faulty power cord, or if you see a lot of red around your unit, it could indicate heat buildup and overheat. Don’t worry; it’s easy to fix both of these issues.
Solution: Replace the cord of your purifier or place your purifier in a cool, dry environment.
On some purifiers, these lights indicate the air quality of your room. Green light means good air quality, orange means a little pollution, and red means highly polluted air in your room.
Problem 3: Honeywell air purifier troubleshooting if it is not turning on

This is another problem that is faced by a lot of people. Here are some reasons and solutions that you can try for Honeywell air purifier troubleshooting.
Fused circuit board
You’ve plugged your Honeywell air purifier in and ensured there are no blockages or defects, but it still won’t turn on. You may just have a bad fuse or circuit board. While you can replace either of these on your own with a quick trip to Home Depot, there are other possible causes for your
Improper wiring
Honeywell is not turning on; if it isn’t getting any power, that could be an issue with a clogged line or faulty wiring. It’s best to call an electrician before trying anything else. If your electrical outlet is working fine, check all wires and connections between your device and its plug—if they look good, try swapping out fuses or circuit boards from another device (such as a lamp) that uses similar parts.
The filter of your purifier is clogged.
A clogged filter can sometimes cause a Honeywell not to turn on. If your vacuum’s main filter is clean, but your machine still isn’t working, check its smaller dust collector filters—those are usually where dust builds up and can block airflow. Remove any obstructions you find here and clean them thoroughly before testing again.
The fan has broken
The fan of a Honeywell vacuum cleaner is controlled by a circuit board, which may also be what’s causing your Honeywell not to turn on. Unlike an air filter, a circuit board can burn out, so you’ll want to call an electrician to check and ensure there isn’t anything else wrong before replacing it.
Improper installation
If you’ve just installed your Honeywell vacuum and it won’t turn on, check if it has been properly connected. Before installing your Honeywell air purifier, read all directions for assembly and maintenance care. Check for any potential hazards or obstructions around where you plan to place your device. Ensure you have installed the purifier according to the Honeywell air purifier manual.
Problem 4: Honeywell air purifier troubleshooting if its screen showing different codes
Honeywell air purifiers sometimes can show some codes as an indication that there is something wrong with your purifier, and you need to pay attention to it. Here are some codes and the reasons behind these codes.
Code: E-01
This is shown by your air purifier when the fuse of the purifier is blown out. To fix this problem, you just need to replace the fuse.
Code: E-02
When your air purifier shows this code, it can indicate that your filter has been overheated. It might be due to faulty wires or improper installation. Call the electrician to make a proper check on your purifier.
Code: L-05
This error indicates that you have a power shortage or a problem with the fuse.
Code: L-07
Whenever your Honeywell air purifier shows this code, it means there might be something wrong with the electrical wires inside your Honeywell air purifier, so to fix this issue, you need to call an electrician or a service center for help.

Problem 5: Honeywell air purifier is not working properly

Honeywell air purifiers are known for their strong suction, but even they aren’t immune to troubleshooting issues. If your machine seems less powerful than usual or isn’t picking up dirt or pet hair at all, there may be some issues. Let’s have a look at these issues and their possible fixing.
A dirty or clogged filter
You’ll know that your filters are too dirty if you notice a decrease in suction power or an increase in fan noise. Make sure to clean your filter once every month and more often if you have pets or smoke in your home. If your air quality is poor, it’s particularly important to clean filters regularly as they can quickly become clogged with dirt and dust. Cleaning them regularly will help them last longer, but you may need to replace them every six months.
The motor is not working properly.
If your Honeywell air purifier’s motor isn’t working properly, you may notice that it makes a loud noise when turned on. To troubleshoot, check for any loose wires or other damage and ensure all your filters are in place. If you still notice a problem, contact Honeywell customer service for further assistance.
You haven’t plugged in properly.
All air purifiers work differently. For some, you’ll need to plug them into a wall outlet, but others come with their power sources. Check your machine’s manual to see if it can be plugged in or needs a special adapter. If so, ensure it is properly connected before starting your unit. In addition, check that your filter is installed correctly.
Improper installation
Make sure to place your machine at least four feet away from heat sources, like radiators or other heating appliances. Heat can weaken plastic components in your machine and interfere with its suction power. If you have multiple Honeywell air filters in one room, ensure they are each on a different wall. Placing more than one filter on a single wall will block airflow and reduce their effectiveness.
The room Is too large than the usual capacity of an Air purifier.
Some air purifiers work best in a small room with a ceiling height of 8ft. Any larger, you’ll start to feel like your machine is less powerful than it used to be.
Problem 6: Stop working after a power outage
If your air purifier stopped working after a power outage, try unplugging it and plugging it back in to reset it. Then go through your settings and check them. You may also need to clean your filter to get everything up and running again. If none works, be sure you’re connected to a dedicated circuit with enough amperage (if applicable), or contact your service provider for more troubleshooting help.
Problem 7: Unable to reset the filter settings
If you just cleaned the filters of your Honeywell air purifier and want to reset the filter settings, but you cannot do so, this may be due to some of the damaged wires inside the air purifier. To call customer service to get this issue fixed.
Problem 8: Honeywell air purifier producing strange smells
Many air purifiers are manufactured in China, so it’s no surprise that there can be an odd smell when you first turn on a new one. But once you run your machine for a few days, it should clear up and not return. If not, then there may be some reasons behind these unpleasant smells.
Producing a plastic smell may be some wiring or piece of plastic burning inside:
You’ll need to disassemble your air purifier and inspect all its internal components. Depending on where you bought it, they may replace it or do repairs free of charge. You’ll also want to ensure all hoses are properly attached, including power supply wires and vacuum inlets.
If your air purifier produces an ozone smell, it’s likely because of a buildup in debris or dust collected around it. These items can be sucked into your machine when you run it, so regular cleaning will help keep these particles away. Just don’t clean your unit while it’s running!
Frequently Asked Questions Honeywell Air purifier Troubleshooting
Here are the answers to your questions have a look.
My Honeywell air purifier’s filter is clogged with my cat’s fur; what to do about this?
If you have a Honeywell air purifier and your cat has been shedding, the fur may end up in the filter. The fur will block the filter’s ability to capture pollutants and bacteria, resulting in bad smells and potential health problems.
To prevent this from happening, take some time every week to clean the filter with a large brush or vacuum cleaner. Make sure to remove all of the hair before replacing it.
How long do HEPA filters last, and when should I replace them?
The average lifespan of a high-efficiency particulate air (HEPA) filter is about 6 months. However, the useful life depends on various factors, including the type of particle and how often it’s cleaned.
Normally, if a company like ours professionally installs your filters, they will do a periodic deep cleaning to keep them in good condition. But even without regular cleaning, HEPA filters should last for several years, provided they’re used in an area where high particles are not expected. You can replace the Honeywell air filter manually.
How do I know whether my Honeywell Air purifier is working or not?
On a basic level, you can tell if your Honeywell air purifier is working by checking the indicator lights. Each light should be illuminated when the device is operating as intended.
Additionally, you can use filters to check for dust and pet dander before they enter your home through the filter unit. If there are particles or smells that are not supposed to be in the air, then it’s likely that your filter needs to be replaced.
You can also test your air quality by putting on a face mask and taking a few deep breaths. If you feel better after doing this, it’s safe to say that the pollutants in the environment have been somewhat reduced thanks to your Honeywell machine.
Should I leave my Honeywell air purifier on all the time?
While having an air purifier running in your home is beneficial, you don’t always need to leave it on. Most experts recommend only leaving them on when they are needed.
This is because humidifiers and other appliances use energy and eventually wear out over time, even if they aren’t used. So just by turning them off every once in a while, you’ll save a lot of energy!
If you do decide to leave your air purifier on all the time, make sure that you consider its replacement cost before doing so. By monitoring the indicator light and replacing filters as needed, you can prolong its life considerably.
Which is the best place to put the Honeywell air purifier in my room?
It would help to consider a few factors when choosing where to place your Honeywell air purifier:
- Think about the size of your room and what type of air quality you’re looking for.
- Consider how often you will be using the device and whether it is important that the machine be close to an outlet.
- Determine whether or not pets or children will be visiting the room frequently.
- Choose a location away from heavy traffic and Noise Pollution Sources (NAS).
Each of these factors should be considered when selecting a location for your Honeywell air purifier.
