The fresher the air we breathe, the likelier we are to enjoy restful sleep without snoring. This leads us to consider the pros and cons of getting an air purifier for the bedroom.
People with sleep apnea, obstructive pulmonary conditions, or allergies are likelier to find an air purifier beneficial. Most homes enjoy a significant improvement in air quality within 3 hours.
Air purifiers should be left running 24/7 with closed windows for best results. Lower the setting to medium or night mode to minimize sleep disturbance.
What Does an Air Purifier Do in A Bedroom?
An air purifier removes microscopic air particles, eliminating unwanted odors, dust, smoke, pollen, and mold spores. They also get rid of dander released by pets from the atmosphere.
This sounds enticing, especially as the journal Atmospheric Environment found that indoor air quality plays a significant role in everyday health.
Neutralizing air pollution is essential to sleep quality, especially if you live in an urban area.
Air purifiers suck air through filters, capturing pollutants and releasing clean air into the room. The filters must be changed periodically to ensure the air purifier works efficiently.
Does A Bedroom Need An Air Purifier?
If a bedroom contains pollutants, an air purifier is normally recommended. All bedrooms have impurities in the air, but pollutants are more likely to accumulate if the following apply:
- You smoke cigarettes or use vapes.
- Free-roaming pets, like cats and dogs.
- Living in a city with open windows for ventilation.
- The home is next to a busy road with air pollution.
- You have a wood-burning stove.
- Spray-based cleaning supplies, like air fresheners.
An air purifier is beneficial if you’ve recently plastered the wall because the appliance will remove fine particles from the air that can’t be seen with the naked eye.
The same applies if you’ve just painted a bedroom. If so, ensure the air purifier model captures volatile organic compounds (VOCs). Carbon air filters are considered the most effective.
How Long Does It Take An Air Purifier To Clean A Room?
An air purifier can cleanse the air in a bedroom in 30 minutes to 3 hours. Some of the factors that influence the speed of purification include:
- Size of the room, as larger rooms with high ceilings, take longer to clear.
- The severity of the air pollution in the room.
- The time elapsed since the last purification.
- Power and quality of the air purifier.
- Whether the windows are open or closed.
You’ll notice a significant improvement in air quality following air purification.
How Much Does An Air Purifier Cost?
The cost of air purifiers varies based on the make and model. An air purifier can cost $100 for an entry-level model or $2,000 to $4,000 for products with high-performance filters and advanced features.
Air purifiers must be well-maintained. You’ll spend up to $100 a year on replacement filters, and as air purifiers are powered by electricity, they’ll cost $5-7 a month to run.
How Long Do Air Purifiers Last?
While some air purifiers last for up to 5 years, most products last for 2-3 years.
Where To Place An Air Purifier in A Bedroom
If you want an air purifier in your bedroom, you must know where to place it.
If you’re wondering, “Can I sleep next to an air purifier?” the answer is yes. The appliance won’t emit radiation or dangerous chemicals. However, it does produce ambient noise and some heat.
The white noise it emits and its heat could keep you awake at night if you’re nearby. Also, an air purifier must be plugged into a wall outlet, so you risk tripping over trailing cables in the dark.
Keep an air purifier about 14 inches from your bed and 2 meters away from other electrical appliances like TVs and computers. Also, avoid anything that could block the filters, like curtains.
Will An Air Purifier Help Me Sleep?
You likely sleep better when you go on vacation to the countryside or some far-off retreat. This is because you’re away from daily stresses and strains and are breathing in pure air.
Unspoiled, unpolluted air in many locations is surprisingly uncommon. This is especially true in cities where opening windows invites plumes of vehicle exhaust fumes and toxins from nearby factories.
Unfortunately, keeping the windows closed isn’t a panacea. However, Indoor Air stated that there are likely even more pollutants in the atmosphere inside a house than outside.
Low-quality air can leave us short of breath at night, resulting in the mind and body exchanging panicked messages, waking us suddenly when our breathing is compromised.
It’s argued that people with respiratory conditions experience the most significant benefits.
A clinical trial outlined in Respiratory Medicine found that purified air reduced bronchial inflammation. An air purifier is good for people with obstructive pulmonary disease like asthma or COPD.
Do Air Purifiers Help with Sleep Apnea?
According to the Annals of the American Thoracic Society, there’s a strong correlation between obstructive sleep apnea (OBS) and indoor and outdoor air pollution.
Obstructive sleep apnea revolves around breathing, stopping and restarting countless times overnight. Improved air quality leads to reduced internal swelling, irritation, and congestion.
Air purifiers with HEPA and carbon filters help with obstructive sleep apnea but aren’t a CPAP alternative.
Most people with an air purifier in their bedroom breathe more easily and snore less.
Do Air Purifiers Help Control Allergies?
Air purifiers trap particulate matter (dander, pollen, dust mites, mold spores, etc.), returning pure air to the bedroom. Removing airborne irritants should help with allergies, but the science is unproven.
HEPA filters remove some (not all) animal dander (skin and saliva) due to their cleverly designed network of fiberglass threads capturing and removing tiny particles.
As particles are just 2.5 microns, aeroallergens can remain problematic for hours before capture.
Most people with allergies enjoy some relief upon introducing an air purifier to their bedroom. However, this doesn’t negate the need for good ventilation and doctor-prescribed medications.
Also, having an air purifier doesn’t mean you can sleep with the windows open in the summer.
Are There Risks To Sleeping with An Air Purifier?
Annoyances, like noise from air purifiers, can cause sleeplessness. If you’re among the affected, moderate noise pollution can be moderated by lowering the overnight setting.
HEPA removes particulates but not harmful gasses and fumes. Also, HEPA filters strip the air of moisture, leading to excessive dryness. If you have a cough and sore throat, it could cause further irritation.
Some models, especially older appliances, produce ozone, which doesn’t remove asthma triggers. The presence of ozone can even exacerbate asthma for some people.
Your energy bills will also increase because you run an electrical appliance constantly. However, high-end air purifiers are energy efficient, so you shouldn’t notice too much difference.
If you’re concerned about running costs, adding plants to a bedroom will be beneficial.
What Is The Best Air Purifier for Sleeping?
If you want an air purifier in your bedroom, consider these important factors:
- Size – You need a purifier big enough to do its job but not so large that it dominates the bedroom.
- Noise – Ensure your choice of model isn’t too loud while it’s running.
- Light – Avoid unnecessary flashing lights that could keep you awake at night.
- Clean Air Delivery Rate (CADR) – The most critical metric, CADR, measures how effectively the air purifier will remove pollutants.
When reviewing the CADR of an air purifier, learn the bedroom size is in square feet. The Association of Home Appliance Manufacturers recommends an air purifier with a CADR of 2/3 the room size.
Most of us will benefit from introducing air purifiers with HEPA filters to our bedrooms. However, not everyone with allergies feels better, so you have to determine how they affect you.
