How Often Should You Change The Filter?
Blueair advises you to change your filter at least once every six months. However, you can change them as often as you see fit, especially if you live in a dusty area. The unit has a filter replacement indicator that lights up when the filter needs to be replaced.
It’s important to note that you cannot wash or clean the filters. You can only replace them. But, the fabric pre-filters can be vacuumed or washed together with your laundry.
And, when the filter light remains red even after replacing the filter, you need to reset the appliance. To reset, press the filter button and hold it down between 5 and 30 seconds. When the light turns from red to blue, you have successfully reset your appliance.

Air Purifier Filter Problems And How To Troubleshoot
The filter can be the cause of some problems in your air purifier. The information below discusses some of these problems and how to troubleshoot them:
Unusual Noises
Don't ignore any strange noises coming from your appliance. To check what is wrong, turn it off and open it. The most common cause is an incorrectly installed air filter. First, check for any damages, and if there are none, re-install it correctly. If it has any damage, replace it immediately.
Dusty Air
The air filter works by blocking out dirt, dust, and debris so that your air purifier can produce clean air. But, if the quality of the air is not clean, have a look at the filters. Dirty filters can compromise the quality of the air you breathe. That is why you need to replace the filters often, as well as regularly wash the pre-filter.
Improper Air Flow
If there isn’t a proper flow of air, you might have forgotten to remove the filter packaging. Open the unit, and remove the packing from the filter.
In addition to this, you may have to check the fan. Increase the speed of the fan if it is low. If the airflow is still not good enough, place it in an area with enough clearance around it.
How The Air Purifier Improves The Quality Of Air Around You
Air purifiers improve the quality of air to reduce health issues, remove odors, and help you sleep better. The ways your purifier does this is by:
Having More Than One Filter
Some purifiers can have two to four filters that can clean the air more thoroughly. Some catch the big particles, and others trap the finer particles.
However, most have two filters, like the Blue Pure 211, which has a HEPA filter that traps particles such as pollen, spores, and large dust particles. Inside it, is an activated carbon mesh that traps harmful chemical odors or prevents off-gassing coming from volatile organic compounds.
By Capturing MPPS
The HEPA (High-Efficiency Particulate Air) filter is important because it filters the MPPS (the most penetrating particle-size particles). The MPPS are the particles that can penetrate your airway walls, causing illnesses.
If you suffer from ailments such as allergies or asthma, a purifier with a HEPA filter can help ease the symptoms.
By Trapping The Tiniest Particles
This is a Blueair purifier suitable for large rooms that you can find on Amazon.
Some of the highest-quality air purifiers can trap particles that are small as 0.1 microns. The coronavirus fits into this category since it has a diameter of 0.1 microns. This virus attaches itself to the respiratory droplets in the air. An air purifier cannot trap the virus, but at least it can catch the droplets.
There are many other tiny viral particles in the air such as mold spores and bacteria. Some of these are not harmful. However, if you are exposed to them for a long time, they can end up causing health problems.
Additional Ways To Improving Quality Of Air Indoors
Your air purifier will work more efficiently when you regularly change the filters. If you don’t do this or change them as per the required schedule by the manufacturer, you may not experience the benefits of an air purifier.
Other steps that you can add to improve the quality of air include:
- To prevent the buildup of allergens, vacuum the carpet and clean the floor at least once a week.
- Indoor plants can help filter the air naturally.
- Use a dehumidifier to minimize the growth of mold and mildew.
- When you are not using your appliance, open the windows to allow fresh air into your home.
In Closing
An air purifier is an appliance that you can find in many homes. It cleans the air, and as a result helps you sleep better, improves any ailments you may have, and reduces allergies. But, for your purifier to work optimally, you will need to change the filters often or as per the manufacturer's schedule.
There are problems that can arise if the air filter is clogged or not installed properly. However, you can troubleshoot these and other problems coming from the filter.
