Do Air Purifiers Improve Sleep? – Yes, Your Body Will Thank You

“Do air purifiers improve sleep?” – We confirm again “Yes, definitely.”

Don’t be surprised, knowing that bedroom air quality can significantly impact your sleep. Of course, other factors also decide whether you would be able to sleep soundly like your mood, the excessive cold or heat, noise, light pollution, or even a messy bedding area. However, air quality is often underestimated.

This is a rather dangerous thing to do because poor air quality possibly affects your upper airways, leading to sleep apnea. Not to mention, bacteria and airborne allergens can cause stuffy noses, sneezing, congestion, headaches, short breath, etc. that wake you up in the dead of night.

Fortunately, air purifiers can help.

Air purifiers enhance your sleep quality in 3 ways:

Getting rid of unwanted particles


How many times do you wake up in the middle of the night because there is something stuck in your nose? The small dust, a strand of pet hair, or the like? Well, no matter what they are, we can all agree that they suck!

Even worse, some airborne particles landing on the skin can cause allergies and widespread rashes. At that time, you might suffer from irritation and itchy feelings that prevent you from getting a sound sleep.

Thankfully, the air purifiers with their HEPA filters can trap almost all particles like dust mites, pollen, pet danders, and even more. Plus, high-quality air purifiers with advanced filters can even do away with invisible viruses, bacteria, and smoke – the dangerous factors that can pretty much be the reasons behind illnesses like cancers, asthma, and other respiration issues.

In the end, only clean air is given back to your bedroom.

Removing annoying molds and odors

Who can sleep soundly in a stinky room?

Even when you clean your house frequently, the high humidity in the air still creates molds at the corners of the room and causes unwanted smells. What’s more, Your pets can also be another source of the undesired odor.

Good to know, some air purifiers can even reduce the humidity level and minimize the odors.

However, remember that not every air purifier can do so. You must go for a machine with the activated carbon filter.

Creating the fresh airflow continuously

Some of you might not know of this, but air purifiers have different “Clean Air Delivery Rate” (CADR rating) and “Air Exchanges per Hour” (ACH rating.)

The former refers to how well a purifier can clean the air within a specific coverage area. Meanwhile, the latter refers to how often per hour the machine will filter all the air within the room.

Reasonably high ratings mean the air in the room is circulated and purified. For that reason, you can sleep longer and better in a healthy bedding environment.

How to Improve Sleep with an Air Purifier?

Now that you have decided to buy an air purifier to enhance your sleep quality, the next step is to know how to use the device properly.

Step 1: Choose a suitable air purifier

Do you want a whole-house air purifier or just a portable unit for your bedroom? Whichever you choose, measure connected rooms into account so that you can figure out a suitable capacity.

Next, consider indoor air quality. Ask yourself vital questions like Whether you need multiple filters to purify the air to the fullest?

Finally, take your budget into account.

Step 2: Put the purifier in the right place

To improve sleep quality, you should invest in at least one air purifier for your bedroom. Of course, it is a rule of thumb to place the air purifier close to the possible source of air pollutants.

For instance, if your partner smokes in the room, place the air purifier where he or she often sits. Also, give the purifier a reasonable amount of clearance between walls and large furniture to streamline the air circulation. We recommend a 360-degree rotating air purifier to distribute clean air evenly. Otherwise, you can also put the machine 10 feet ahead of your bed and let it point toward you.

And where is better: on the floor or the table?

There is no clear answer to this. It depends on the construction of the air purifier. Still, regardless of where you choose,  remember not to pose the machine as a trip hazard for your children.

Step 3: Turn on/off the device at the right time

For your sake, you might spend 8 hours and more in the bedroom.

Of course, you can turn on the purifier all the time because the indoor air is constantly changing. Especially when there is a smoker in your family or you have babies and kids.

However, to keep the electricity bill from being overcharged and the machine from overworking, you should leave the air purifier on whenever you and your family are present in the room.

More effectively, go for models with auto turn-on/off function. They will flexibly adjust the settings based on the impurities in the air.

Step 4: Run low settings at night

Noise is one common source of sleepless conditions. Unfortunately, the fan in the air purifiers is pretty loud and can disturb your dream. At that time, the tool does more harm than good.

Ideally, you should consider getting quiet air purifiers such as the Blueair’s HEPASilent.

One last thing: At night, keep the windows and doors closed, if possible, to prevent outdoor air from invading and the clean air from leaking out.

Step 5: Maintain and replace the filters frequently

The standard HEPA air purifiers trap the harmful particles through the filters. Those filters become dirty over time and lose their max capacity. Even worse, some particles might find their way back to your indoor air once this happens.

Hence, you must clean and maintain the filters as well as the outer cover periodically. Moreover, tidying up your bedroom every day to minimize the sources of air pollution is a must.

Most importantly, read the manual guide carefully to figure out the time of replacement and make the change – even when the purifier does not clog much.

Wrapping Up

After reading this blog, have you got yourself the answer to  “Do air purifiers improve sleep or not?”

Yes, It does. And, every household should have at least one air purifier in the bedroom – the place you might spend your time more than any other place. Not to mention, having a sound sleep every night will keep your mind fresh – the very next morning.

Anyhow, Before you go, keep in mind that “ Prevention is better than cure.” In addition to the air purifier, you should also reduce your carbon footprint inside and outside the bedroom for a better living environment.
