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.

How to Find the Right Air Purifier for Your Bedroom

The most important factor when shopping for an air purifier is to know the size of the room where you plan to use it.

Measuring the room now will save you hassle and disappointment later. Go get your measuring tape. Don’t worry; I’ll be right here when you’re done.

Okay, now that you’ve multiplied the length by the width and you know how many square feet you need to cover, you’re ready to continue.

Airflow Is Key

With respect to air purifiers, it’s always better to err on the side of bigger. If you have a 200 ft.² bedroom, and you purchase an air purifier designed for rooms measuring 300 ft.² or more, you’ll be pleased with how well it works. You may never need to put it on the highest setting.

Air purifiers are rated for the entire size of the room as well as airflow. For example, here’s an example of CFM (cubic feet per minute):

CFM = Length x Width x Height x (Air Changes per Hour) divided by 60 minutes

200 CFM = 10 x 20 x 10 x 6 / 60

Therefore, this would be an air purifier that can exchange six roomfuls of air per hour.

CADR is another way to help you choose the best air purifier for your home. It stands for Clean Air Delivery Rate.

The higher the number, the better the filtration.

Also Consider These Features

Besides looking at the capacity of the air purifier, you’ll want to consider other features and facts.

First, how noisy is it? If you’re a light sleeper, never purchase an air purifier that makes more than 30 dB of noise.

Second, are you prepared to support the long-term costs? This includes replacing the filters and paying for the electricity. Happily, most air purifiers don’t use a lot of power.

Third, are there multiple speed settings? Does it have built-in sensors? Is there a remote control or a timer?

These are all factors that may influence your decision.

Now let’s look at the top bedroom air purifiers to help you find what you need.

Coway AP-1512HH Mighty Air Purifier

Coway’s Mighty Air Purifier is a top pick for many online review sites and magazines.

It provides good performance, has convenient features, and isn’t very expensive or difficult to maintain.

Although there are different models, the one we selected covers rooms up to 361 ft.². It has a CADR of 246 for dust, 240 for pollen, and 233 for smoke.

There are four stages to the filtration system. The pre-filter catches large particles and dust, and it’s washable. Then there is a deodorizer that removes cooking odors and reduces volatile organic compounds.

Next, a True HEPA filter captures 99.97% of particles like pollen and pollutants. Finally, there’s also a Vital Ion filter.

Choose from three fan speeds or auto mode. The automatic mode drops to eco-mode to save energy if no pollution is detected for half an hour.

In fact, the purifier has a colored LED to show you how clean your indoor air is.

Also, there is a timer and a filter replacement indicator light.

It’s rated for 77 W power consumption and 24.4 to 53.8 dB depending on the speed setting.
