Best Air Purifiers For A Bedroom


The air in your bedroom may not be as clean as you think, and in fact, it may be leading to several health problems ranging from asthma and allergies to poor sleep quality.

The bedroom is where most people spend the majority of their indoor time.

Many families are therefore installing air purifiers in their bedrooms to ensure that they have access to clean, breathable air around the clock.

Finding the perfect air purifier for your bedroom, however, can be a rather daunting task. You need a purifier that clears out most of the pollutants, is small enough to fit your space, quiet enough to let you sleep in peace and also set at a price that you can afford.

With so many options available in the market with considerable variations in the price, appearance and performance, a new buyer can be easily confused.

If that sounds like you, then in this post we’ll discuss ten of the best air purifiers available in the market today and compare their features to help you pick the right device for your bedroom.

Let’s get started.

Why Do I Need An Air Purifier For My Bedroom?

According to a WHO report, air pollution kills up to 7 million people every year. One may expect that most of these deaths are a result of pollution from vehicles, forest fires and the like, but almost half of these are actually attributed to pollutants found inside your house.

In fact, according to the EPA, some pollutants can get concentrated inside your house, or bedroom, almost 2 to 5 times higher than outdoors!

Many of these indoor pollutants are biologic (which includes animal dander, mold and dust mites, among others), while some are chemical (including radon, asbestos, lead and smoke from stoves).

These substances pose a risk to your health, causing problems ranging from:

  • Irritation of eyes
  • Respiratory diseases
  • Heart diseases
  • Even cancer.

For instance, asbestos, commonly found in old decorative ceilings, is a known cause of lung cancer. Similarly, dust mites and pet dander are known triggers for asthmatics.

Considering how the average American spends approximately 90% of their time indoors, these health risks cannot be ignored.

An air purifier is a device that is especially designed to remove pollutants from your home so you get to breathe cleaner, healthier air.

While no air purifier can deal with heavy amounts of pollution, many offer a great degree of filtration to clear out most contaminants from the air.

Best Air Purifiers For Your Bedroom

With this information, let us look at 10 of the best air purifiers that you can purchase for your bedroom based on their aesthetics, performance, cost, noise and overall functionality. Feel free to click on the images or links for more information on Amazon about each air purifier.

1. Blueair Blue Pure 311 Auto

The Blueair Blue Pure 311 Auto has got almost every feature you can ask for in an ideal air purifier for your bedroom, including compact size, aesthetic appearance, fantastic performance, quiet functioning and an affordable price:

The first thing you’ll notice about the Blueair Blue Pure filter is its unique design that appears almost custom made for a bedroom.

The sleek cylindrical device with a fabric finish has a small footprint of just 10.2 inches but stands tall at over 20 inches. As a result, the filter not only ‘fits’ your room but can even enhance its appearance.

The most attractive feature about this device, however, is its capable of completely filtering the air in a master bedroom of up to 388 sq. feet within just 12.5 minutes of starting.

It filters out more than 99.97% of fine particles including dust, pollen, viruses and other particulates less than 0.1 micron in size.

This performance is better than that offered by most devices on our list. This is due to its combination filter that includes a fabric pre filter, a true HEPA filter and an activated carbon filter that work together to remove particulates of varying sizes, ensuring that you get clean, healthy air at an amazing speed.

This performance, in fact, has been independently evaluated and certified by Association of Home Appliance Manufacturers (AHAM), making it an impressive choice for many customers who are skeptical of the performance offered by most air filters.

The Blueair Blue Pure air purifier is impressively quiet, keeping the noise at 23 decibels at normal functioning (like a whisper) and up to 53 at maximum capacity (which is about as loud as a household refrigerator).

Additionally, the Blueair Blue Pure 311 Auto goes a step further and provides users with features like auto mode setting and an LED air quality display that gives you real time information on the quality of air inside your room. It also includes a dust and a gas sensor, which is lacking in most devices on our list today.

The device has been priced at $249.99 and is available on Amazon.

2. Conway AP-1512HH Mighty

With sleek aesthetics, high filtering performance, low noise and an affordable price, Coway AP1512HH Mighty is another great air purifier that you can get for your bedroom today.

At first glance, the Conway Mighty air purifier looks quite futuristic with its glossy black and silver finishes, but the minimalistic appearance still manages to fit a regular bedroom without appearing out of place.

The purifier comes in a handy size of 16.8*9.5*18.3 inches and a weight of 12 pounds, making it one of the more compact devices in our list today.

Where the device truly stands out is in the wide array of features it provide along with a stellar filtering performance. Suitable for rooms up to 361 sq. feet, it uses a four-stage filtering mechanism.

  • At first, the air passes through a washable, permanent ‘pre filter’ which catches larger particles like dust, pet dander and hair, making the air healthier for people with allergies.
  • The next stage is the activated carbon filter that acts as a deodorizer for your bedroom air.
  • Next, the air passes through a true HEPA filter that removes even more minute particles like viruses and dust particles as small as 0.3 microns.
  • The final filter is an ionizer that traps any particles which may have escaped the previous filters, giving you clean, fresh air to breathe.

The device can function in three manual speed modes, but there is also a fourth ‘auto’ mode that can automatically adjust performance based on the level of pollution in your room. Additionally, there is an ’eco’ mode that keeps the filter at standby when the air does not need filtering.

Another feature that makes the purifier suitable for bedrooms is how quiet it is, producing less than 54 decibels of sound even at maximum capacity.

It also comes with a pollution sensor that shows the quality of your bedroom air in real time using bright colored LEDs, and an indicator to let you know when it is time to replace the filter unit.

All these features are available to you at $170 to $204 on Amazon.

3. Conway Airmega 200M

In contrast to the Coway Mighty, the Conway Airmega 200M differs significantly in terms of the aesthetics. With a size of ‎21.42 x 19.53 x 11.89 inches, the device comes with a rectangular grille and a black glossy finish. It weighs more than the Mighty as well at 17 pounds.

The Coway Airmega 200M is another great air purifier that combines an amazing filtering performance with energy efficiency, low noise and an attractive array of features, making it one of the best choices for your bedroom.

When it comes to functionality, however, the Coway Airmega 200M perfectly mirrors the Coway Mighty as it, too, is equipped with the same cutting edge four-stage filtering mechanism designed to remove dust, pet dander, odor and even minute particles like viruses from a room of up to 361 sq. ft.

It also comes with a timer, an eco friendly low energy consumption mode, a pollution indicator and a replacement indicator, making it an extremely user friendly device especially suitable for first time buyers.

This filter is available at around $224 on Amazon.

4. Levoit Core 400s

The Levoit Core 400s stands out in our list not only because of its attractive look and high filtering capacity but also because of its quiet functioning and smart features like voice control and an inbuilt smartphone app.

The filter is cylindrical with a height of 10.3 inches, a diameter of 9.7 inches, and comes with a textured white finish. It also weighs very little at just 1 kilogram, meaning you can easily set it on top of a side table or an ottoman and you won’t even notice the filter is there.

Despite the compact size, Levoit has spared no detail when it comes to performance. It is equipped with a high efficiency activated carbon filter, a preliminary nylon filter and a true HEPA filter that the company claims is safer than medical grade surgical mask materials.

Combined, these filters can remove up to 99.97% of dust, smell and allergens as small as 0.3 microns from a bedroom of up to 270 sq. ft within just 8 minutes.

In addition to these, the filter comes with its own veSync app that enables you to monitor the quality of the air in your bedroom, receive notifications or change purifier settings remotely.

You also get a voice control feature where you can link your purifier with third party softwares like Amazon’s Alexa to control the purifier entirely with your voice.

This can therefore be a great choice for someone looking for easier control in addition to basic filtering performance as it offers additional features at roughly the same price as others on our list.

Available on Amazon for around $220.

5. Levoit LV H128

If you are looking for a budget device that offers most essential features and functioning without breaking your bank, look no further than Levoit LV H128.

The device is quite small at 6.7*6.7*10.4 inches and has a portable weight of 3.3 pounds. The appearance is not exactly spectacular, but the compact size makes it easily fit into most spaces with appearing too out of place.

Performance-wise, the Levoit LV H128 is suitable for small to medium sized bedrooms of up to 161 sq feet.

Like many others, it too consists of a preliminary filter, a true HEPA filter and an activated carbon filter than can remove up to 99.97% particles as small as 0.3 microns, including dust, pollen, pet dander, mold, or even odors from the kitchen.

The filter is also incredibly quiet, running at a sound as low as 28 decibels in sleep mode.

In contrast to many other filters we are discussing today, it also has the added feature of functioning as an effuser for essential oils and aromatics.

Where the Levoit LV H128 truly stands out is in its budget. It is priced at only $50 on Amazon, making it the undisputed best purifier available for its budget range.

It does lack some features like the replacement indicator or a real time air monitor, but the incredibly affordable price still makes it one of the best investments that you can make, especially if you are a first time buyer and want to test an air purifier out before deciding to make a bigger purchase.

6. Fellowes Aeramax 100

Another great addition in the budget category is the Fellowes Aeramax 100, which, although not as established as some of the other brands on our list, offers an incredible performance combined with an attractive design and affordable prices.

The design appears very unique at first glance with its slender shape and dimensions of 8.5*7.5 inches at the base and a commanding 27 inch length.

It comes in a glossy white finish and a black inset with clean, minimalistic blue buttons/display, making it particularly suitable for clean, minimalistic rooms, or for those that prefer a futuristic, ‘tech-y’ look.

It is designed for relatively small rooms of 100 to 200 sq feet.

It uses an advanced four-stage hospital type filtration system that includes:

  • An activated carbon filter for odors and large airborne particulates
  • A true HEPA filter for germs, allergens and mold
  • An ‘Aerasafe’ antimicrobial layer to offer additional protection against germs, and
  • A plasmatube ion emitter that safely removes additional airborne impurities.

The filter also offers an ‘Aera Plus’ mode that increases the air turnover rate by up to 35%, which is particularly suitable in case of added pollution from smoke or traffic.

A few users have complained that the device did not last them very long, but at a price less than $140 on Amazon and a three year warranty, we do not think this should be too concerning.

7. Winix 5500-2

While not the most affordable purifier in our list, the Winix 5500-2 offers a great value for money with excellent room coverage, four different fan settings, and an eco friendly washable carbon filter replacement.

The device has dimensions of 15*8*23.6 inches and weighs 15.4 pounds. With only a charcoal grey color available and its broad face, many would not find the design truly attractive or user friendly.

What it lacks in design, however, it makes up for in performance.

Like most other air purifiers, it consists of a prefilter, a true HEPA filter and an activated carbon filter that can reduce majority of pollutants from your air, but also features a hydroxyl releaser to neutralize bacteria and viruses. 

The filter is AHAM certified for a large area of 360 sq feet, and unlike other filters, the activated carbon filter is also washable, making it a great choice for those concerned about their impact on the environment.

Additionally, the device also features a remote control system (that most other filters lack), an LED air quality indicator, four different fan settings which can be changed manually and also based on its automatic sensors.

It also features an auto mode, a light sensor and a quiet sleep mode feature to increase its energy efficiency.

It is available on Amazon for around $150.

8. Blueair Classic 605

If your bedroom (and your budget) is particularly large, then the Blueair Classic 605 may be the perfect choice for you.

Owing to its capacity, the device is rather bulky as one would expect at 13*20*26 inches dimensions and a has massive weight of 31 pounds.

As such, this is not a purifier that you will be shifting around as per convenience.

The performance, however, is praiseworthy. Few filters of its price range are AHAM certified to clean out air from a bedroom as large as 700 square feet within just 12 minutes of operation.

It uses its HEPAsilent technology that is capable of filtering out up to 99.7% of viruses, mold, smoke, odors, pollen and most other contaminants.

At low speed, many customers have noted its whisper quiet functioning, though at high speeds it does tend to get noisy.

It is also one of the few devices on our list that has an Energy-star rating for energy efficiency, as well as a 5 year warranty to go with the purchase. Additionally, it offers many useful features like voice control, smartphone control and wifi connectivity.

However, these features do come at a price. You should note that the annual operating costs including replacement filters can also go quite high, making it unsuitable for small to medium rooms.

The only caveat to this filter is it’s hefty price of just shy of $500 on Amazon.

9. Germguardian AC4825W

Although seemingly simple at first, the Germguardian AC4825W air purifier is unique in terms of its filtering mechanism and its design, making it an attractive choice for bedroom air purifiers in the $100 to $200 price range.

The filter has one of the best designs in our list today, featuring a sleek 10.25*6.75*21.5 inch tall frame in a black and a white finish.

The elegant design is topped with a silver cap and a metallic blue rim that houses the control buttons.

The filtering mechanism includes a prefilter, a charcoal filter and a true HEPA filter like the majority of devices on our list, but it also includes a UV-C light that helps reduce airborne biological contaminants and a titanium treatment layer to go with it.

The company claims that it makes the filter especially suited to remove viruses and bacteria in air, but some users have complained that the blue light is rather distracting.

The filter is suitable for rooms up to 167 sq ft and can function at three interchangeable fan speeds.

The noise level however is higher than most purifiers we have discussed today with an intensity of 40 Decibels even in its lowest setting (which is a bit quieter than a fridge).

The filter does not come with smart features like wifi connectivity, but considering its price range, the performance and design, it is certainly worth the investment.

10. Alen Breathesmart Classic

Although the last mention on our list, Alen Breathesmart Classic Air Purifier has the largest filtration capacity of any filter we have discussed today and comes with an equally large size (and a price tag) to go with it, making it especially suitable for those with large master bedrooms or open concept floor plans.

The 21 pound device is 10×17.75×26.75 inches in dimensions and is available in multiple color options including white, graphite, brushed stainless, espresso, weathered gray, and oak.

It uses a medical grade filtration system that removes 99.99% harmful airborne particles including dust, dander, allergen and pet fur using the usual prefilter and four different advanced HEPA filter options.

It is capable of cleaning a massive 1100 sq ft area every 30 minutes, meaning it is definitely not suitable for a typical bedroom, but can be an amazing option if your bedroom is particularly large or if you have an open floor plan.

It is also unusually quiet with just 49 decibels even at high performance setting.

Lasting more than three to five months longer than ordinary filters, the Alen Breathesmart Classic offers the additional function of a soothing sound (called ‘pink noise’) with sleep friendly frequency. 

There are also the usual features of an LED indicator to display room air quality in real time and has an energy star certification for efficiency.

The filter is available at $649 and above on Amazon.
