5 Best Air Purifiers For Bedroom In 2022: Compared, Reviewed, Rated (2022)

Where to place an air purifier? In the bedroom, of course.

According to the EPA, we spend up to 90% of our time indoors (alongside the 2x to 5x more polluted air than outdoors). At least 8 hours per day is spent in the bedroom (if we’re lucky). That’s why bedroom air purifiers are the ones most people want to get.

All air purifiers can be placed in the bedroom, but not all air purifiers are best equipped to be bedroom air cleaners. There are some requirements for the best bedroom air purifiers to follow. These include:

  • Silent operation. Nothing over 60 dB.
  • True HEPA filters to capture even the smallest air pollutants.
  • Ability to deem lights.
  • Preference: Smartphone controls. Because when you’re tucked in your bed, the last thing you want to do is to untuck and change the air purifier’s setting.

Air purifiers for bedrooms are designed to be left on all night.

We will cover the 5 best air purifiers for beds, based on these criteria, and with the respect to the specification such as coverage area, CADR rating, airflow, and filtration system. All of them filter out the most common bedroom air pollutant: Fine dust, and other allergens.

Before we look at all of them, a word about the Alen BreatheSmart series. BreatheSmart is the only air purifier series with validated dependent ScoreSleep Lab studies. In essence, all Alen BreatheSmart air purifiers were specifically designed (and tested) to improve the quality of sleep.

Here are the findings of this bedroom air purifier study:

These specs might not be the easiest to understand. Let’s look at some of the key one. We’ll start with the most important part of all bedroom air purifiers: Filtration System.

Filtration Systems, Appropriate For Bedroom Air Pollution

To pick the best air purifier for bedrooms, it needs to have a filtration system that can capture air pollutants we commonly find in bedrooms.

The main bedroom air pollutant is dust. For dust removal, it’s essential that the bedroom air purifier has a HEPA filter.

HEPA filters are tested to capture more than 99.97% of dust particles that are as small as 0.3 microns in the bedroom. Along with problematic dust particles, HEPA filters also capture pollen, smoke particles, and other allergens that might hamper your sleep.

In the bedroom, we also find a larger concentration of large air pollutants like hair, as well as unpleasant odor (sweat, for example). It’s not hard to understand why:

We spend 8 hours per day sleeping. All the hair that falls out and all the sweat we produce during that time stays in the bedroom.

That’s why best bedroom air purifiers include two additional filters, namely:

  • Pre-filter for larger particles. This takes care of hair, pet dander, and protects the HEPA filter.
  • Activated carbon filter for sweat odors. This charcoal filter adsorbs gaseous air pollutants mechanic filters like HEPA and pre-filters are unable to remove.

The result of this 3-stage filtration is alleviated bedroom air quality.

Some air purifiers can have additional filters. Hathaspace HSPoo1, for example, includes an extra pre-filter that is necessary if you have an above-average concentration of fluff in your bedroom – that usually happens if you have pets; dogs or cats just love sleeping with us.

CADR Rating For Bedroom Dust, Pollen, And Smoke

The CADR rating is the most important metrics that tell us how efficient bedroom air purifiers are at removing 3 main air pollutants. These are:

  • Dust in the bedroom. Specifically, 0.09-1.0 µm dust particles frequently found in sleeping areas.
  • Pollen in the bedroom.
  • Smoke in the bedroom.

Air purifiers are independently tested by AHAM to measure the CADR rating. The average CADR rating is about 200. For better, it’s best to get a 200+ CADR rating air purifier in order to significantly improve bedroom air quality.

Bedroom Coverage: Small, Standard, And Large Bedrooms

It’s important to properly size an air purifier to the square footage of your bedroom. According to CreditDonkey, an average bedroom size in a home is 219 square feet.

If you check the comparison of the best air purifier for the bedroom above, you can see that all of them have a maximum coverage area above 219 sq ft. Does that mean that all of them would be most appropriate even for a master bedroom?

Not at all. The recommended room coverage is just square footage manufacturers use (usually based on 2 air changes per hour). For a bedroom, it’s recommended to use 5 ACH in the square footage calculation.

That means that all the air in a bedroom would be exchanged every 12 minutes; recommended for areas with high allergen concentration. It’s always better to buy a little bigger air purifier for bedrooms in order to ensure the highest bedroom air quality during the nights.

For reference, here are the bedroom sizes:

  • Small bedroom: 100-200 sq ft.
  • Standard bedroom: 200-400 sq ft.
  • Large bedroom: 400+ sq ft, including master bedrooms.

Now, let’s look at the one metric that really matters during the nights:

Quiet Operation That Doesn’t Bother Your Sleep

Bedroom air purifiers should be running all through the night. Of course, the silent operation is essential for that. When you place it in the bedroom, the distance between where you sleep and the position of the air purifier is usually 10 feet or less.

The choice of the best bedroom air purifier must take noise levels into account. Many air purifiers can produce more than 60 dB while running at full speed. Alen BreatheSmart 45i, for example, produces only 49 dB at the highest speed.

Many bedroom air purifiers have the so-called Sleep Mode. That’s the rest mode; people do confuse it with ‘Mode-While-Sleeping’. When you actually go to sleep, you don’t put an air purifier in the bedroom into Sleep Mode. You just reduce the fan speed setting to medium, or even low. Noise levels at that speed are very quiet.

Before we look at the review of individual air purifiers that are best fit for bedrooms, here’s another unnecessary but useful feature:

Smart Air Purifiers – Smartphone Connectivity

Older air purifiers are controlled via the purifier’s own display. Some even have remote controllers. The modern bedroom air purifier can be controlled via a smartphone.

For bedroom air purifier, this is a convenient feature. The last thing most of us look at before falling asleep is a smartphone.

It’s quite handy to use a smartphone app to control the air purifier in the bedroom. That means you don’t have to untuck, go to the air purifier, set the fan speed, or dim the lights.

Smartphone connectivity might sound unnecessary until the very moment you have to remove your blanket. Then you quickly realize that every top-rated bedroom air purifier should come with the smartphone app.

With all that in mind, let’s look at the very best air purifiers for the bedroom. And none is better than the Alen BreatheSmart 45i:

Bedroom Air Purification FAQ

A bedroom is where air purifiers are most commonly used. Can they be used all night, and do they improve the quality of sleeping? We’ll answer these and some other questions about bedroom air purifiers below:

What Is The Best Air Purifier For A Bedroom?

The best air purifier for the bedroom is silent, has a high CADR rating, a HEPA-based filtration system, and so on. All these qualities are joined best in the Alen BreatheSmart 45i. That makes it the best bedroom air purifier.

Of course, if you have a big bedroom, Coway Airmega 400 might be a better option.

All in all, check for silent operation and high CADR rating. Those are important for efficient removal of dust, pollen, and smoke particles from the bedroom, and peaceful sleeping.

Do Air Purifiers Help You Sleep Better?

We do know that high indoor air pollution might be negatively impact sleeping patterns. For example, a higher concentration of allergens might cause more allergic reactions.

Air purifiers do remove allergens and increase the quality of bedroom air. Therefore it might be prudent to conclude that air purifiers help you sleep better. However, scientific studies that connect the sleeping quality with air purifier directly, are few. Studies usually research the relationship between sleeping quality and indoor air quality.

One study, conducted by SleepScore Labs, shows that Alen BreatheSmart air purifiers positively affect how well-rested we wake up.

Is It OK To Leave Air Purifier On All Night?

Most air purifiers are supposed to run 24/7 to continuously keep the bedroom air quality high. That, of course, also includes the nights.

It is OK to leave an air purifier on all night. That’s exactly what you should do. Knowing air purifier will run all through the night prompts air purifier producers to design quiet units.

If you don’t get one of the quietest bedroom-friendly air purifiers, you can still reduce the fan speed setting in order to reduce the noise levels of that particular device. Quiet operation and sleeping go hand-in-hand.

Is It Bad To Sleep In A Dusty Room?

When we sleep, we breathe in the surrounding air. If the surrounding air has a high concentration of dust, that dust will enter our lungs, and might even trigger smaller responses measured by the body.

That doesn’t necessarily mean that sleeping in a dusty from is the worst thing that can happen. Fortunately, however, we have methods to increase indoor air quality like opening a window or using an air purifier.

It’s actually very easy to decrease the total concentration of airborne dust in a room.
