5 Best Quiet Air Purifier for Bedroom (Small & Silent)

5 Best Quiet Air Purifier for Bedroom (Small & Silent)

Dealing with air pollutants and noise in the streets in bad enough, but it becomes an annoyance when the same invades your home.

See, a home is meant to serve as a sanctuary where you can enjoy peace and serenity. Though air purifiers usually provide respite from the polluted air, many of them are a nuisance due to the noise they generate.

A noisy appliance is more than an annoyance, but it makes it difficult to hold conversations and can disrupt a good night’s sleep.

But does this mean that you’ve to sacrifice your peace over clean air? No. You can still enjoy the benefits of an air purifier and still maintain serenity at your home.

But this goes down to choosing the right air purifier. In my comprehensive review guide below, I have compiled the top 5 quiet air purifiers in the market.

All the purifiers on my list have a lower than average noise rating and are highly adjustable to suit the needs of various environments including the bedroom and bathroom.

Here are the Top 5 Quiet Air Purifiers for the money

1. Rabbit Air MinusA2 SPA-700A

The Rabbit 700A ticks all the boxes for the best quiet air purifier. From the top-notch filtration system, noiseless operation, expansive coverage to multiple fan speed, the Rabbit 700A is a big jump from its predecessor Rabbit BioGS 2.0 and a worthy rival to the big guns.

Design and Size

The Rabbit 700A is part of the Rabbit Air Minus edition. Visually, the Rabbit 700A is nothing like other Rabbit Air Purifiers.

The Rabbit 700A is visually appealing, thanks to the customized panel featuring images from artists such as Claude Monet, Van Gogh to Hello Kitty.

As such, the Rabbit 700A is more than an air purifier, but can also complement the aesthetics of your house. Dimension-wise, the Rabbit 700A comes with a slim profile, measuring 24 x 22.8 x 9.8 inches.

The subdued profile makes this unit an incredible option where space is of the essence. Simple and elegant, this unit is highly adjustable and can either be mounted and stand on its own.

Finally, weighing 9.4 pounds, the Rabbit is among the lightest units in the market, making it easy for you to move it from one place to the other.

Filtration System

Filtration is the most crucial criterion for determining the power of a purifier. Rabbit 700A offers a multi-stage purification, a six-stage system that works to remove almost all the air contaminants. The six filters on this unit include;

  1. Pre-filter: It captures all the large particles including pet hair and dust mites
  2. Medium filter: Traps large pollen, mold, pet dander and any other large particles that have passed the pre-filter
  3. Advanced BioGS HEPA filter: This is a true HEPA filter that captures 99.97% of 0.3 microns allergens, fungi, mold, and more.
  4. Customized filter:  This filter allows you to customize the filter depending on your needs. Popular filters here include pet allergy, germ defense, Odor Remover, or toxin absorber
  5. Activated carbon filter: Eliminates odor, smoke, and any chemical vapors
  6. Ion generator: The last line of defense will allow easy trapping of particles.

Besides optimal air purification, I love the idea that you can customize the purification system to meet your demands.

Room Coverage

Though the Rabbit 700A is the least in size in its class, it offers generous room coverage of up to 700 square feet. It’s the most extensive coverage I’ve come across, and its more than sufficient to cover your living space, bedroom, or even office space.

Noise Rating

The Ultra Quiet Air purifier tag on the Rabbit 700A is simply not for commercial purposes, but there’s a reason behind it.

Most of the air filters boast of a quiet mode, which utilizes thinner filters and a lower speed fan. Rabbit 700A, on the other hand, uses a brushless DC motor technology that utilizes coiled copper wires to move electric current.

Given that the motor does not overheat, the fan on the Rabbit 700A runs quietly.

The air purifier has a 5-speed fan setting, and at its lowest setting, the fan is virtually noiseless. Generally, this unit operates at a noise rating of between 20.8-45.6 dB.

Additional Settings

The Smart Sensor technology will automatically adjust the fan speed depending on the quality of air in the room. This helps to keep the air purifier consuming optimal energy and saving energy.

The Light sensor technology allows the Rabbit to transition to sleep mode in a dark room, making the unit a suitable option for bedroom use.

Rather than using a remote control, the Rabbit can be operated wirelessly using its in-built Wi-Fi function. Finally, there’s no need to remember to replace the filters, since the unit has a LED Life Indicator to remind you.

2. The Coway AP-1512HH resembles a gigantic iPod shuffle.


Sporting a slim and streamline body, the Coway measures 24 x 22.8 x 9.8 inches. Now, it’s ironic that the Coway has been dubbed as the ‘Mighty” Coway, yet the size does not depict the same.

However, Coway is not mighty in size, but instead in performance. Despite its compact size, this multi-filtration unit is performance-oriented. This makes the unit an ideal option for those with allergies.

Design and Size

The Coway AP-1512HH shares design cues with the low tier AP-0512NH. The front and the back of this unit are covered in sturdy plastic, and this renders the unit durable and hardy.

Regarding aesthetics, the Coway has plenty of similarities with an iPod. Out of the box, this unit is a candy to the eye and offers a luxurious look.

This unit is elegant and feels premium. Regarding dimension, the Coway sports a modest dimension of 16.8 x 18.3 x 9.6 inches, further buttressing its suitability for homes with smaller spaces.

Filtration System

The filtration system on this unit can be described as close to perfection. Though a low-tier air purifier, the Coway does not sacrifice on any of its components.

Instead, Coway offers a robust multi-filtration system. This unit offers 4-stage filtration, which is higher than the 2-stage filtration I often see we the standard air purifiers.

The 4-stage filtration includes;

  1. Pre-filter: Captures the large particles.
  2. Activated-carbon filter: Deodorizes and keeps the harmful gases away from your house
  3. True-HEPA filter: The HEPA filter capture 99.97% of down to 0.3 microns of fungi, pollen, and mildew.
  4. Ionizer: Ionizer boosts the overall purification and keeps the air fresh.

Room Coverage

The Coway AP-1512HH can effectively cover a room of 360 square feet. It a considerable drop from what we had earlier seen on the Rabbit 700-A, but still sufficient to cover a modest living room, apartment, and middle-sized spaces.

Sound

The Coway AP-1512HH is a bedroom-centric air purifier, and as such, it generates white noise, a soothing ambient noise that will help you get to sleep easier.

The Coway has three fan speeds, and at the lowest settings, this unit generates 23.4 decibels. Now, if you know anything about the noise, this noise-rating is similar to a whisper, and in real-world use, it’s hardly audible.

At its greatest settings, 54 dB, this unit still generates reasonable and tolerable sound, underlining its suitability as the best quiet air purifier for bedroom.

Additional Features

The Smart Sensor alongside the Eco Mode will help to adjust the fan speed depending on the air quality in your room.

The Eco Mode will further help to optimize the overall operation of the unit and keep the power usage as low as possible.

This is an incredible option, especially for those who are always worried about the annual electricity bill.

3. Winix 5300-2 Air Purifier with True HEPA

The Winix 5300-2 is part of the 5300 model, and it offers unique styling, alongside an incredible performance. With an impressive 4-stage filtration, Winix has a similar coverage of 360 square feet, similar to that of Coway.

The Winix does not shy away from practicality, and it comes with a plethora of features such as the timer, AQ light, and sleep mode.

A selling point of the Winix is PlasmaWave technology. This is an innovative technology that helps at getting rid of bacteria, viruses, and other harmful particles.

Design and Size

Winix 5300-2 is a floor-standing model, but not too high. Maintaining a small base, this unit is slimmer and lighter as well.

Weighing around 17 pounds and with a dimension of 14.9 x 7.8 x 23.6 inches, this unit is compact and highly portable.

I like how the controls have been placed at the top of this air purifier. Therefore, rather than kneeling to operate the purifier in a ridiculous position, you’ll now press the button easier.

Filtration System

The Winix 5300-2 is a budget option. However, contrary to what you would expect with budget equipment, Winix does not feature a poor quality air cleaning system.

Rather, it offers a premium 3-stage filtration system, which is more than respectable spec for a low-end purifier such as the Winix 5300-2.

The filters on this unit include

  1. Pre-filter: It filters the large particulate matter. The pre-filter is attached to the activated carbon filter, and it helps to free your air from odors
  2. True HEPA Filter: The HEPA filter capture 99.97% of down to 0.3 microns of fungi, pollen, and mildew.
  3. Winix PlasmaWave: It’s akin to an ionizer, and it helps in refining the purification process by considerably reducing the number of pollutants. However, unlike the common ionizer, PlasmaWwave technology is an innovative technology that works by releasing positive and negative ions. This helps in creating hydroxyls, which are responsible for destroying the airborne pollutants.

Coverage

The Winix 5300-2 offers coverage of 3,600 square feet. While the coverage is low, it’s quite standard for air purifiers in this budget range, so nothing alarming.

Noise Rating

I am really impressed with the noise rating on this unit. At the lowest settings, the Winix 5300-2 offers an incredible noise rating of 28 decibels.

Additional Features

The Smart Sensor feature will automatically detect changes in your indoor air quality and will notify you through an LED indicator.

If you’re running on Eco Mode, the air purifier can adjust the fan speed to match the indoor air quality.

The smart sensor and eco mode function will not only optimize energy consumption, but they negate the need for remote control.

4. Blue Pure 411 Air Purifier 3 Stage

Blue Pure 411 is an intriguing entry-level air purifier. Sporting a lightweight design, this unit comes with a minimalistic and futuristic design.

A product of Sweden’s Blueair, the Blue Pure 411 is a suitable option for a variety of classes, including those dwelling in polluted areas, the health-conscious folks and those with compromised immune systems.

Design and Size

As we had mentioned in the beginning, the Blue Pure 411 comes with a compact and modest design.

Like all the best quiet air purifiers on my list, this unit comes with an elegant design and is ideal for complementing your home décor.

Regarding dimension, this unit is really compact, measuring 16.7 x 8 x 8 inches. The compact dimension on this unit buttresses its suitability as the perfect table air purifier.

Regarding weight, Blue Pure weighs a mere 6 pounds and is currently among the lightest air purifiers in the industry.

Filtration System

Blue Pure provides a multi-stage filtration system. This unit will provide you with up to three stages of filtration.

The filters on this unit include;

  1. Pre-filter- traps the large particles Particle filter: Rather than using the True HEPA Filter,
  2. Blue Pure 411 utilizes polypropylene fibers, which are less or more effective than the HEPA filter.
  3. The Particulate filter captures 999% of the air allergens and pollutants

Activated Carbon fiber: This filter is used for removing odors, gases, and smoke. Sure, the filtration system, especially the particle filter, is not as effective as the true HEPA filter.

However, this does not mean you can simply write off this unit. In any case, the manufacturer has used a unique

HEPA Silent technology and advanced combination of mechanical and electrostatic filtration that guarantees effective purification.

Room Coverage

The room coverage on the Blue Pure is limited to 161 square feet. For a bedroom-centric purifier, the coverage is still decent and worth it.

Noise

The Blue Pure comes with three fan speeds. At maximum fan setting, this unit generates a maximum sound rating of 46 decibels.

This unit is incredibly quiet, and at the lowest setting, it generates 17 decibels. The low noise on this unit is attributed to the HEPA Silent technology, which increases the airflow and capacity, while at the same time reducing the speed of the fan.

Additional Features

Well, at this price, there have to be sacrificed. And one such sacrifice is the lack of additional features. Here, you will not have the liberty of a Smart Sensor or even a timer.

5. Honeywell True HEPA Allergen Remover

Honeywell is a well-known brand, and it’s synonymous with rugged durability and quality. The Honeywell HPA 300 is optimized for removing the various air pollutants from the air.

It’s specially engineered to eliminate allergens and ensure they don’t reach your nostrils. It’s a suitable option for homeowners looking for an economical air purifier that will work on a relatively large space.

Design and Size

There’re no drastic changes to the overall design cues of Honeywell and that of its predecessors. While the lack of differentiation makes this unit look a bit bland, it’ practical and does not fail.

The metal construction, in particular, renders this unit sturdy and hardy. With a weight of 24 pounds and a dimension of 20.08 x 10.83 x 22.32, the Honeywell is not the lightest unit.

The measurements on this unit are a tad large, and not ideal for users with small spaces.

Filtration System

Honeywell is a true HEPA filter, and for its price, this is not really a surprise. This multi-stage filter has several filters, which include:

  1. Pre-filter- Removes large particulate matter. The pre-filter on this unit is in combination with an activated carbon filter, and as such, it requires constant replacement.
  2. True HEPA filter: The heart of the filtration on the Honeywell. This filter captures up to 99.97% of as small as 0.3 microns pollutants such as dander to allergens.

Room Coverage

Honeywell has the second largest room coverage, only second to that of Rabbit 700A. With a formidable coverage of 465 square feet, this unit can cover large spaces in your household.

Better yet, the generous room coverage comes alongside an incredible air purification performance.

Noise Rating

The noise rating is probably the hugest setback on this unit. Though the manufacturer has not clearly indicated the actual noise rating, Honeywell has a relatively higher noise rating compared to other air purifiers within its class.

Rather than using a silent setting, the manufacturer uses a turbo setting. Nonetheless, while the unit is not suitable for bedroom purposes, it does not sound like a tractor and can be used in the living space.

Additional Features

Though the manufacturer has not included a Smart Sensor, users can enjoy a plethora of other features such as a timer, three fan speeds.

The Turbo Mode on the unit will boost the overall performance by maximizing the fan and is ideal for use for extreme allergy situations. However, the turbo mode will generate a lot of noise.

What to Look for in a Silent Air Purifier

Choosing an ideal air purifier is a challenging task, especially if you don’t know what to look out for. In the section below, we shall look at some of the critical factors you need to consider when searching for the ideal air purifier.

Noise levels

Noise rating is probably the most important factor to consider when choosing the best quiet air purifier. Having a quiet generator is probably what has inspired you to check on my list.

Ideally, when searching for a quiet purifier, you should look for those with a noise rating of below 60 decibels when full capacity.

On the lower side, some of the units usually go as low as less than 20 decibels, and they’re ideal for use in the bedroom or quiet spaces such as libraries.

Fan Speeds

Fan speeds determine how effective an air cleaner is at removing air pollutants in the air. The more speeds a unit has, the greater the adjustability; i.e., selecting higher speeds will result in faster and efficient cleaning of the indoor air.

Coverage Area

The coverage area is the space in which a unit can clean the air effectively. Ideally, the choice of your air purifier should be inspired by the size of your household space.

As a rule of thumb, however, its always recommended going with a purifier with extensive coverage as opposed to that one with smaller coverage.

Dimensions

The dimension refers to the size of the unit. Again, the size of the air purifier should be inspired by the size of your household.

You don’t want to get an overly big air purifier making it draw all the attention from the rest of the household equipment.

At the same time, understand that size correlates to performance, and therefore, getting an extremely small air purifier might limit its efficacy.

The trick here is to strike a balance between size and functionality.

Extra Features

Though most of the extra features are always a luxury, it would not harm having them in your air purifier. Some of the essential extras that you might consider;

  • Smart Sensor
  • Timer
  • Auto-shutoff

Conclusion

Air purifiers are integral equipment in our households. Finding one that fits your needs should not be challenging anymore. Hopefully, our top 5 quiet air purifiers should provide a model that will fit your needs
