Do air purifiers help you sleep better?
Let’s look at the facts.
At least one in every five people has allergies (1).
Allergy flare-ups cause congestion and other respiratory problems.
But the best bedroom air purifiers remove pollen, mold, dander, and other allergens from the air.
When you can breathe easier without a stuffed-up or runny nose, you’ll sleep better, too.
Air Pollution Causes Poor Sleep
Unfortunately, it’s not just dust and allergens that cause you to lose sleep.
Other pollutants like small particulates (PM 2.5) and gases like NO2 (nitrogen dioxide) interfere with your rest (2).
Symptoms are more severe for those with asthma, respiratory illnesses, and cardiovascular disease.
With wildfires happening more often, air pollution is affecting more people these days.
How Air Purifiers Make It Easier to Breathe
Typically, air purifiers use a fan to draw air through a filter to screen out pollutants like allergens.
Most of them use a HEPA filter to mechanically remove 99.97% of particles larger or equal to 0.3 µm (3).
But regular HEPA air purifiers don’t get rid of odors or gases, so they often have an activated carbon filter as well.
They may also have a pre-filter that catches pet hair or dust.
As a result, when you purchase an air purifier, you can be sure of two things.
One is that you’ll need to replace filters on occasion. Depending on usage, it could be every few months or every couple of years.
And two, if you’ve never used one, you’re going to love having an air purifier because you will breathe easier like never before. [Read more…]
