Air filters such as Honeywell air purifiers help eliminate bad odors and improve the airflow inside the house. Yet, sometimes, it can be annoying when the unit starts to indicate errors. Don't have any idea what to do when your Honeywell air purifier's "Check Pre-Filter" is turned on? We've researched this topic, so you don't have to!
The "Check Pre-Filter" light on your Honeywell air purifier will turn on when the pre-filter is already clogged with dirt and needs replacing.
You can replace the pre-filter and then press the "Check Pre-Filter" button for 2 seconds until the light stops blinking. Your air purifier should resume working without errors after doing so.
It can be overwhelming when your air purifier keeps on showing error signs. If you're wondering how to stop the error lights from blinking, we will dive into further details about this topic, so stick to the end of this post to learn more.
Honeywell Air Purifier Says Check Pre Filter - What To Do?
A Honeywell air purifier helps provide better airflow within the house. It can clean the air in rooms of up to 465 sq. ft. amp space. Honeywell manufacturer also claims that it can get rid of up to 99.97% of microscopic air particles from 0.3 microns because of its three-stage air filtering system.
This provides better and cleaner air within the household, but if the pre-filter of the device is clogged with dirt, the air purifier will have a hard time. Good thing Honeywell air purifiers have built-in indications to let you know when your pre-filter and filter need to be changed.
The "Check Filter" and "Check Pre-Filter" lights on the left part on top of the device will help you know which filter needs to be replaced. Otherwise, the error message will not go off until you change the dirty filter.
However, there are instances when you've already replaced the pre-filter, but the error light is still blinking. When this happens, all you have to do is reset the pre-filter.
To reset the pre-filter light after changing the pre-filter, press the "Check Pre-Filter" and hold the button for two seconds until the light refrains from flashing. This feature helps users know when the pre-filter is saturated with dirt and other air pollutants.
When and How To Replace The Pre-Filter In Your Honeywell Air Purifier?
The pre-filter in a Honeywell air purifier is used to eliminate odor and smoke. Unlike the HEPA filter that can last 3-5 years, depending on how frequently you are using the air purifier, it is recommended to replace the carbon pre-filter every three months.
When the pre-filter is already clogged with dirt and bigger debris of air pollutants, the air purifier's motor will require more energy to work since the blockages in the pre-filter impedes the proper air regulations.
You can do a weekly check-up on your air filter to ensure that the pre-filter is in good condition, or you can check the pre-filter light in your device to know if you need to change the pre-filter.
If you have no idea how to replace the pre-filter by yourself, here is a simple guide you can follow.
- Turn off and unplug the unit to avoid electrical hazards.
- Remove the grill on the front side of the air purifier. Hold the upper right corners to do this and press it until you hear an audible click.
- Remove the pre-filter. The pre-filter is the black rectangular filter placed in front of the primary HEPA filter.
- Insert the new carbon pre-filter into the tabs to secure it in place.
- Place the grills back and turn the unit on.
- Reset the pre-filter light by pressing the "Check Pre-Filter" button for two seconds until the light stops flashing.
Can You Wash a Honeywell Air Purifier Filter?
You can use a vacuum to clean the HEPA filter twice a year, but Honeywell does not recommend reusing the carbon pre-filter if you want the pre-filter to continue filtering odor and smoke.
The carbon pre-filter will no longer be efficient in clearing up odor and smoke after three months of usage. It can still filter visible air particles. Although some filters are washable, cleaning them with water can make the filter's pores bigger, making it harder for the filter to trap air pollutants.
Why Should You Use a Pre-Filter in Your Air Purifier
Remember that the carbon pre-filter is your air purifier's first line of defense. It traps visible particles such as dust. Since the primary HEPA filter has a fine mesh, more significant air pollutants can easily clog it. That's why the carbon pre-filter filters the air before passing through the main filter.
In addition, the pre-filter helps the primary HEPA filter to last longer since it catches the bigger particles from reaching the primary filter. Also, carbon pre-filters can neutralize volatile organic compounds. These are types of gasses that cause health issues when absorbed by the body.
Although pre-filters have a shorter lifespan than the main HEPA filters, pre-filters are made of cheaper materials, so they are less expensive than the main filter.
Can I Keep My Air Purifier Running All Day?
Yes, you can. Air purifiers are designed to keep the air within the space free from pollutants.
However, letting your air purifier on all day will consume more energy. In addition, you might need to replace or clean your filters more frequently when doing so. When running an air purifier all day, you can set it on its lowest setting to reduce noise production.
Honeywell air purifiers have light indications that will tell you when the filters should already be replaced. These light indications are located on the left of the top part of your Honeywell air purifier.
Can An Air Purifier Help Cool The Room?
Generally speaking, air purifiers are not designed to cool down the temperature in a room since their components are created to provide cleaner air within the space by pulling the air and filtering it before circulating it back into the room.
However, you might think that the air purifier lowers the temperature level when its fan directly points at you. You are experiencing this sensation because air purifiers have fans that help the device circulate the air while filtering it. Some air filters draw air from the ceiling downward. That's why it is good to keep these air purifiers on during winter.
On the other hand, there are summer-friendly air purifiers as well, though air purifiers are not designed to decrease or increase temperature levels. All it does is circulate the air while filtering it.
Can You Turn The Air Purifier On When Sleeping?
Leaving it on at night can help you sleep better since it regulates cleaner air. Study shows that air purifiers can help improve the quality of your sleep by providing cleaner and better air circulation within the room.
Purifiers help eliminate pollutants that can irritate the lungs, nose, and eyes. This soothes the body during sleep by making your breathing zones pollutant-free.
In addition, air purifiers do not produce the same level of noise air conditioners produce, so it's less likely that air purifiers can ruin a good night's sleep.
Wrapping It Up
Air purifiers are becoming more and more essential these days due to their health benefits. Always maintain your Honeywell air purifiers by paying attention to their filter and pre-filter lights. Maintaining a clean pre-filter will not only help clean the air within the space. It will also help your device last longer.
On top of that, we should ensure that we are inhaling healthy air free from harmful pollutants. Taking care of your air purifier by paying attention to its filters is one way of doing this.
