Will An Air Purifier Help You Sleep Better?

An air purifier will improve on your sleep quality by removing 99.97% of the irritants in the air as small as 0.3 microns e.g. dust, dust mites, pet dander, mold spore, pollen, and bacteria. With cleaner air, you will no longer have to deal with allergies like, stuffy nose, chronic sneezing, sinus, headache, shortness of breath, or choking cough that causes you to stay awake at night. By placing an air purifier in your bedroom, you will sleep faster, able to reach deep sleep, and wake up feeling completely refreshed the next day.

Air purifiers can also produce white noise for those that enjoy sleeping with a soothing background sound. The equal frequencies wavelengths act as calming ambient sounds or relaxing lullaby for the baby. The white noise generated from the air cleaner’s fan can also drown out external noise e.g. TV from the living room, neighbor, highway. Some air cleaners like Alen BreatheSmart HEPA FIT50 produce pink noise that is scientifically better than white noise by 25% according to one study. This is because pink noise blends into the background with a lower soothing tempo without the irritating high pitch sounds.

Little do we know that fresh air can also cool down the room temperature, burn calories, and rest easier. An air cleaner circulates clean air and prevents air from being stagnant. Having purified, fresh air means there are fewer allergies to breathe in and deprive us of sleep. With a night of good sleep, our health is able to restore physically, mentally, and emotionally.

Can You Sleep With An Air Purifier On?

You can and should leave the air purifier on all night while you sleep. This is because air purification is a continuous process from the constant air quality shifting. Turning an air purifier off may result in indoor pollutants to build up overnight. A good example is chemicals like formaldehyde, VOCs, or radon that off-gas from flooring, furniture, and wall. Outdoor pollutants like Carbon monoxide will also flow into our home through cracks in walls or gaps between windows and doors. As an air purifier will need to run for at least a couple of hours to clean the air after a restart, we might be inhaling the toxic gases without us realizing it.

Is It Safe To Sleep With An Air Purifier?

It is perfectly safe to sleep with an air purifier on as it is designed to run day and night without fail. For better safety assurance, make sure the air purifying device is UL listed or AHAM certified. If you have any concerns about the surge in electricity bill, glaring LED light, or fan noise, pick a model that comes with Auto mode and Sleep mode e.g. Winix 5500-2 or MinusA2. In auto mode, the air purifier will automatically adjust the fan speed accordingly when there is a high volume of pollutants detected. When there are low pollutants in the air, the air cleaner will remain in low speed to conserve energy and keep the noise level down. In Sleep mode, the air cleaner will maintain the fan speed to low and dim down the indicator light.

Frequently Asked Questions FAQ

Do Air Purifiers Help With Sleep Apnea?

Having an air purifier in the bedroom can help with sleep apnea by capturing all the bad allergens in the air. Clean air can make a huge difference to a person with sleep apnea. Research from the American Thoracic Society shows that sleep apnea is linked with prolonged exposure to air pollution. Sleep apnea is a sleep disorder where a person stops breathing for 10 to 30 seconds repeatedly in their sleep due to airway blockage. When you breathe comfortably throughout the night, you will snore less, enjoy better sleep quality with longer sleeping hours. You will unlikely suffer from grogginess, gasping for air, or waking up in the middle of the night with a HEPA air cleaner.

What Are The Causes of Sleep Problems?

Chronic sleep deprivation is linked to many health issues. According to research, air pollution can increase poor sleep conditions up to 60 percent compared with those that lived in clean air areas. Inhaling to PM2.5 pollutants, fumes, and bad odor can irritate our lung's respiratory system. When a person does not have enough sleep, it will affect their health, mood, work performance, and concentration level. If you are suffering from Chronic Idiopathic Insomnia that takes hours to fall asleep, here are some of the know causes.

  • Physical - For example headache, chronic pain, headaches, fibromyalgia
  • Medical - For example asthma
  • Psychiatric - For example depression, anxiety disorders, stress
  • Environmental - Air pollution, bright street light, outside noise, partner snoring, weather, dirty room
  • Genetics - For example narcolepsy, a neurological disorder

What Are The Signs Of Sleep Deprivation?

If you sleep on time consistently yet still feeling sleepy and tired the next day, you could be experiencing poor quality sleep due to allergies. Having insufficient sleep could cost you dearly on academic and career performance. You could be failing an exam, missing out on a deal of a lifetime, or a big promotion because you constantly zoned out. Here are the symptoms to look out for:

  • Constant yawning
  • Moodiness/ easily irritated
  • Fatigue/ drowsiness
  • Clumsy
  • Depressed
  • Forgetfulness
  • Inability to concentrate/ inattentiveness
  • Lack of motivation
  • Increased in appetite

Poor air quality is one of the common reasons for sleep deprivation. Investing in an air purifier can help you get through the night by capturing all airborne impurities.

What Type of Air Purifier Do You Need?

There are many types of air purifiers that can remove impurities in the air while you slumber. From HEPA air purifying machine, Odor eliminator, UVGI cleaner, PCO air cleaner, Ionizer, to Electrostatic precipitation. Knowing the kinds of contaminants that lead to poor sleep can help you decide which air purifier to buy. If you are having trouble with dust and non-gas particles, a filterless air cleaner will do just fine. If you are living in a heavily polluted industrial area that is constantly exposed to unpleasant smoke and odors, you will need an air purifier with a carbon filter.

Ultimately a HEPA air cleaner is always our recommended type. It is safe, supports multi-layer of filtration, and can remove gas and non-gas particulates including odors. Look for the following filtration:

  • Pre-filter - The first-stage filter designed to block out large particles like dust and hair.
  • True Hepa Filter - Look for a model that comes with a True HEPA filter rather than a HEPA-type filter.
  • Activated carbon filter - A must-have filter to remove strong fumes, smoke, and unpleasant odors.
  • Ionizers - Electronically charge particles in the air so it will fall for the air purifier to capture.
  • UV-light - Very effective in killing sleep disruptive bacteria and viruses.

Notice we did not include an ozone generator in the list here because it is a dangerous device that can aggravate your health instead of improving your sleep issues.
