Honeywell Air Purifier Making Loud Noise (Solution)

by Josh M

The air in your home can be a breeding ground for pollutants like dander, mold, dust, and more. [1] This is especially compounded if you live in a particularly polluted area with poor air quality. [2] If you want to keep breathing easy in your home, a high-performance air purifier and a vacuum can do wonders.

However, all machines encounter issues eventually; read our best tips and tricks for Honeywell air purifier loud noise troubleshooting below.

Debris Inside The Unit

Over time, bits of dust and trash can end up in your air purifier, making it difficult for the air purification process to operate properly. In this case, debris can refer to any scattered piece of rubbish or dust. If you hear rattling or see the fan not moving correctly, there may be debris in your air purifier.

We recommend:
  • Turning off and unplugging your machine
  • Open it up by removing the cover according to the owner’s manual instructions [3]
  • Carefully listen for where the noise comes from and remove or clean debris away
  • Try cleaning and replacing your filter if necessary
  • Replace everything
  • Plug in and turn on
  • Reset if necessary

Filter Not Correctly Installed

Once you have cleaned or set up your new filter or prefilter, it can be easy to not quite get the positioning right when reinstalling them. If you find that the change filter indicator is still going off even after a clean or new one is in, you simply need to adjust the position and reassemble. Once done, reset your air purifier if necessary.

Filter Needs To Be Replaced

Honeywell replacement filters and prefilters need to be changed every few months, depending on usage. The filter change indicator system does a wonderful job of letting you know when the time is right.

If you leave a dirty or clogged filter running without cleaning or replacing it, it can cause the air purifier to make odd loud noises or even overheat and damage itself. We recommend carefully cleaning and replacing your air filter and prefilter as soon as possible.

Filter Clogged Up

The bits of debris we mentioned earlier do not always rattle around in the cavities of your air purifier. Some larger dust or particles can get stuck in your air purifier and clog it, disrupting the airflow.

Cleaning or replacing your air purifier filter or prefilter according to manual instructions is often the best way to fix the issue. If there is a heavy amount of dust and debris on the filter, you may want to gently wipe away any excess from the internal HEPA filter container.

Dust On Ioniser Pins

Static electricity and too much dust can cause the ionizer pins to tick randomly. If this happens, we recommend unplugging and opening up your air purifier cover to expose the ionizer pins. Once you can see them, use a can of compressed air to remove any dust from them before reassembling and turning the air purifier back on.

Air Purifier Location

Your Honeywell air purifier noise level can be affected by its location and positioning in your home. You need to ensure that your model is well ventilated and not blocked or covered by anything while in use. You can put it on the ground, near the worst pollutant (in the kitchen or near the cat litter box are popular choices), or on a table. We recommend keeping it away from corners and facing it into the room instead of at the wall.

High Speed Fan Has Issues

As your Honeywell air purifier HPA200 gets to work, ensuring your air quality is as good as it can be, it will naturally make some noise. This should filter out into the background and can change depending on the settings that you choose; the higher the fan speed, the noisier your fan will be.

If the high-speed setting is too loud, simply turning it down to a slower setting should help. Also, confirm that your air purifier is on a flat and stable surface to prevent the feet from clattering on the surface.

Air Purifier Model Has High Decibels

All machines tend to make noise while in use, even if the sound is very quiet. While searching for Honeywell purifiers, we recommend checking their product description or manual to learn their standard noise levels. Some other brands or models tend to be louder than others, and knowing the rough estimates in advance can help you avoid some of the noisier ones.

However, this does not help if you already own a loud one. If your Honeywell air purifiers are running a little loud, we recommend either changing the program for another one, moving to another room, or listening to something else with headphones in.

Explaining Honeywell Air Purifier Types Of Noise


There are a few reasons why most air purifiers may make a beeping noise. For some, simply changing your settings or the program could cause an operational beep to indicate the change happened. Alternatively, a repeated beeping sound may mean that you need to change the filter or reset the system according to the owner’s manual.

In the case of repeated beeping, we would suggest changing or cleaning your HEPA filters and resetting the system. If this does not work, it would be best to contact customer service for a technician appointment.[4]


A clicking noise often means one of two things in the world of air purifiers. On the one hand, it could mean that the ion pins just caught a particularly large bit of pet dander or dust mite debris. Alternatively, it could mean that the motor is calibrating while in use.


Another common air purifier noise can be described as a crackling noise. This can be similar to the ionizer clicking but means something a little bit different. This crackling tends to mean that either your HEPA filter may have just trapped a particularly large piece of mold, dander, or other contaminants.

If these unusual noises happen very frequently, it may mean that either your Honeywell international model needs filter cleaning or for you to purchase a replacement.


Another common air cleaner sound can be described as whispering while in operation. This typically means that the fan is operating normally, often at a low speed. If this is the case, then there is nothing to worry about; if you are concerned, contact the Honeywell International Inc customer service team through their website.


For some units, a hissing noise can mean that the air quality sensor is scanning or operating as normal. Alternatively, the unit may be about to power down.

If it was not supposed to power down, you may want to confirm that your air purifier is still plugged into the outlet and that the fuse and electrical supply are all in working order.

Whistling Noise

An air filter making a whistling noise can mean that the prefilters or HEPA filters are clogged, in which case cleaning or replacing them and resetting the filter light should help. Alternatively, you may want to consider inspecting the exhaust and intake grilles to confirm that they are not being blocked by debris or smoke particles.

If this whistling noise continues after removing what is blocking the model, one of your Honeywell air purifiers may be damaged or defective; contact the customer service team for further assistance and to hire a technician.

Common Honeywell Air Purifier Frequently Asked Questions

Is an air purifier supposed to make some noise?

Many air purifiers will make some noise as they work to remove any smoke or other nasty smell from the air. People who use their air purifiers often will get used to having a certain background level of noise, but loud ones may signal a maintenance check is needed.

What should be the noise level for an air purifier?

The standard noise level for an air purifier depends heavily on the brand, model number, whether it is in turbo or auto mode, where you install it in your home, and more.

However, a good guide could be that extremely quiet models tend to operate at 15 dB, good air purifiers often run at 32 dB, and most air purifiers tend to run at around 36 dB or more.

Which Honeywell air purifier is the quietest?

Defining which air purifier is the quietest is difficult as the lowest setting will often be the quietest, and the acoustics in your home will play a factor. However, we recommend that you look carefully at the product descriptions as you search Honeywell and other sites like Amazon before you purchase for the sound level indicator.

Can my Honeywell air purifier be on all the time?

While it may seem like a good idea to run your purifier from an outlet all the time, we do not recommend it.

This is because all machines decrease in performance the more they are used and, despite some advertising suggesting otherwise, would increase the amount of power your home uses. So save your wallet and increase the machine’s lifespan, and only use it when you are home.


Having an air cleaner unit and vacuum in your home can do wonders for ensuring that your home feels comfortable and safe. If you are having trouble with your air purifier’s sound level, we recommend getting in touch with the customer service team via the Honeywell website to avoid placing your air purifier under unnecessary stress. They will typically be able to help fix or replace your unit after confirming the model number.
