Should You Sleep With An Air Purifier On? Here Is The Truth


Most of us know that a regular night of sound, restful sleep is the cornerstone of a healthy and happy lifestyle. Physical and mental health depends on getting enough sleep, and studies show that those who make a decent night’s sleep a habit live longer. While one may be aware of the significance of sleep for health, one may not know the connection between sleep quality and air quality.

According to a recent study, airborne contaminants and inadequate ventilation have a considerable negative impact on sleep. Dust, pet hair, human dander, mold, and other allergens are prevalent in bedrooms. These have the potential to trigger respiratory irritations that keep people up all night. Using an air purifier in your bedroom can help in overcoming poor indoor air quality while sleeping. Many of the top air purifiers available today have a “sleep mode” setting that allows to enjoy all the advantages of an air purifier while minimizing additional problems that would negate the purpose and keep you awake.

What Does The Air Purifier’s Sleep Mode Do?


Every owner of an air purifier is aware of its sleep mode. But how does it function? The machines often change the CADR to adapt to the working noise. And the sleep mode’s CADR determines whether it is appropriate for a bedroom. Many people are accustomed to switching on the automatic gear for a lengthy run in the bedroom. This eliminates worries by allowing the air purifier to automatically alter the wind speed and gear position in response to variations in the ambient air quality.

The air purifier makes the slightest noise and has the lowest CADR score, making it the best for sleeping. A bedroom air purifier can typically accommodate rooms from 50 to 112 square feet when in sleep mode. If the air purification system is not working, you might check to see if it is in the fitting room.

Is It Okay To Use An Air Purifier While Sleeping?

According to the US Environmental Protection Agency, air pollution is the root cause of 68% of human ailments. The immune system is at its weakest when a person is sleeping. At this period, the human body is more vulnerable to invasion by pathogens, viruses, and other hazardous substances. A Harvard School of Public Health study also discovered that air pollution could stimulate the central nervous system, lead to upper respiratory tract infections, aggravate sleep-disordered breathing, lead to apnea, and result in hypoxia. This is especially true in the summer when pollution levels are high.

Let’s now address the subject of whether or not an individual can sleep with an air purifier on. The air purifier is ideal for sleep since it removes various airborne contaminants, such as formaldehyde, germs, viruses, and PM2.5. It makes home safe and one can also replicate the natural environment by cleaning the air. People can sleep well in a comfortable setting because negative ions help people coordinate with the living room.

4 Benefits Of Using Air Purifiers While Sleeping


More than one may have imagined, air purifiers can help improve sleep.

1. An Air Purifier Protects Immune System

Our immune systems are too weak to defend against germs, bacteria, or other microscopic dangerous substances. Through the air, they might enter our bodies and harm our health. An air purifier can help us in this situation, especially for those who frequently shut their windows and doors while they sleep. Some hazardous microorganisms thrive in a contained environment like a room.

As a result, the constantly produced toxic compounds are breathed into the mouth and nose by the human body, creating a variety of unpleasant reactions in the body and even leading to severe sickness. They can be effectively removed using a HEPA air purifier with a HEPA filter.

2. Air Purifier is Compatible with All Seasons

People prefer to sleep with the air conditioner in summer or winter. In contrast, overused air conditioners are more likely to produce a significant amount of pathogenic bacteria in the filter, including Escherichia coli, Staphylococcus aureus, Bacillus, and Legionella. In an air-conditioned room, the indoor oxygen level will decrease by 13.2% after 5 to 6 hours. The air conditioner’s breeze blows these bacteria into the bedroom, which can induce uncomfortable reactions in persons with weakened immune systems while sleeping. An air purifier can remove all contaminants in various temperatures, keeping you always in an environment with clean air.

3. Air Purifier Gets Rid of Formaldehyde


In a new home, air contaminants, including formaldehyde and the benzene series, are constantly volatilized throughout the year. Its concentration is frequently considerably higher in the air that does not circulate at night than when the windows are opened for ventilation during the day, which will also result in more severe harm to human health. So, use an air purifier in the bedroom. It’s also suggested that should use the air purifier at night.

The bedroom is where the air purifier is set up to work. It can rely on its potent adsorption abilities to draw dangerous airborne contaminants into the body, filter and purify through the filter, and then release clean, healthy air, ensuring the user’s sleep.

4. Sleeping with Air Purifier Makes Minimal Sound

The air purifier is more essential, though, when sleeping at night. Most people would put one near the foot of the bed, where it can effectively cleanse the air within and lessen the effects of noise on sleep.

One need not worry about noise in the bedroom when choosing a silent air purifier because they all offer sleep features. Most air purifiers’ sleep gears make a noise of roughly 30 dB, and anything less than 35 dB is barely audible when we are sleeping quietly.


Time must be as valuable and nourishing as possible as we adjust to the new normal and spend more time at home. It’s essential to choose air purifiers that improve indoor air quality and support a comfortable, relaxing environment if one wants to have a healthy, tranquil, and fulfilling home life. An air purifier’s built-in sleep mode capabilities will assist in creating a clean, non-intrusive environment.
