9 Best Small Air Purifiers - Reviews

1. Pure Enrichment PureZone 3-in-1: Best Small Room Air Purifier

Key Features:

  • 3-stage filtration removes 99.9% of particles
  • Activated carbon filtration
  • Built-in ultraviolet light for extra sanitation
  • Ozone-free filtration 
  • Energy-efficient and easy to use

The PureZone 3-in-1 came onto our radar because it has 9,359 ratings on Amazon that average 4.5 stars. With this high number of positive ratings, we knew our team had to try this small air purifier out first. The 3-in-1 uses an activated carbon filter to clean allergenic particles from the air and a built-in ultraviolet light for extra air sanitation. 

UV light is used in filtration systems to kill or inactivate airborne pathogens and microorganisms, such as viruses, mold, or bacteria. If anyone in your home is sensitive to colds and viruses, UV light filtering might help.

The true HEPA filter further cleans the air, resulting in some of the cleanest air available. The 3-in-1 only weighs 6 pounds, which makes it portable and easy to place anywhere in your room. It can fit on a shelf, end-table, or right beside you as you work from home. For its size, it is capable of purifying a large amount of air. The PureZone 3-in-1 can filter a 200 ft2 room.

Pros

  • Filters generate no ozone
  • Ultra-quiet on low and medium fan settings
  • Small size requires little space
  • Reduces reactions to pet dander

Cons

  • Carbon filter replacements are expensive

Who Should Get This? 

If you have a home office and are allergic to pet dander, the PureEnrichment 3-in-1 works best in small spaces and eliminates dander from the air.

2. Intelabe HEPA Air Purifier EP1080: Best for the Money

Key Features:

  • 3-stage filtration system
  • The air filter has a fragrance sponge
  • Brushless motor for 22 dB ultra-quiet operation
  • Minimal size – 6.3” diameter
  • Removes 99.9% of particles in the air

Many air purifiers do a fantastic job of purifying the air in a room. The EP1080 is no slouch in the purification department, removing 99.9% of particles in the air, such as pet dander and pollen. The additional touch of a fragrance sponge is something that truly makes this little purifier stand out. 

One reviewer mentioned that her teenage son’s room had never smelled so good, a testament to this little unit’s purification power. The air is taken in through an inlet on the front of the unit and then dispersed through the swirled fan guard on top. The top-dispersion design allows the clean air to circulate through the entire room, filling it with clean, scented air.

If you have a room that needs a purifier and something to reduce the smell, the EP1080 is a powerful little unit that can stand up to the worst odors. If you need to purify a room and are on a budget, this is an excellent purchase.

Pros

  • Can be placed anywhere
  • Quiet enough for use during sleep
  • Filters air and adds a scent
  • Reduces the amount of dust in a room

Cons

  • Very loud beep when turned on

Who Should Get This?

Key Features:

  • Smart air quality sensor
  • 3-stage filtration system
  • Removes 99.9% of air contaminants
  • Timer and child lock feature
  • 3-speed fan with auto- and sleep-modes

The Toyuugo KJ-350B is another excellent air purifier capable of removing 99.9% of all air contaminants from the air in your room. The 3-stage filtration system uses an advanced ultra-fine pre-filter, a HEPA filter, and a photocatalyst filter

Photocatalyst filters use ultraviolet light to catch the particles in the air that cause smells, while the HEPA and pre-filter remove larger particles. 

The KJ-350B is slightly larger than some of the other small purifiers on the market, but with the increase in size comes an increase in the unit’s cleaning capacity. A room of up to 215 ft2 can be purified, with a noise level of 20 dB in the quietest mode. The increase in room size coverage means that you can place this unit in almost any room in your house. 

Toyuugo designed this purifier with a very modern look to match nearly anyone’s room design. It comes in either black or white. If you have a small- or medium-sized room you’d like better air quality in, the KJ-350B is a fantastic choice.

Pros

  • 20 dB quiet mode for sleeping

  • Removes smoke from the air
  • LED changes color with air quality

Cons

  • Replacement filters are expensive

4. Hokeki Air Purifier VK-6067B: Best for Open Floor Plan Homes

Key Features:

  • Smart air quality sensor and indicator
  • 3 speeds and 2 modes
  • A triple-stage filtration system
  • 3 timers and memory function
  • Clean Air Delivery Rate of 7,770 ft3

Choose up to 5 different settings with 3 speeds and 2 modes to find the optimal setting for your room. The VK-6067B can be set to operate ultra-quietly or put out as much air as a pedestal fan (with about the same noise level). 

At 17” tall, this unit is taller than many other small purifiers on the market, but it is only 7.5” in diameter. The small diameter means you can place it just about anywhere in a room, and while it weighs 8 pounds, it is not too heavy for a sturdy shelf.

If you’re looking for a purifier that functions well while looking great at the same time, the VK-6067B has a very stylish look that fits into any style of home decor. The clean air delivery rate of the VK-6067B is 7,910 ft3 per hour.

A room size of 1,100 ft2 can be cleaned by this small purifier so that you can use it in living rooms or large entertainment rooms, or in the smaller rooms in your house. 

Pros

  • Colored LED air quality indicator
  • Removes all smells from the air
  • Sleep mode is nearly silent
  • The tube design is more appealing than a box-like shape

Cons

  • Slightly larger than other small purifiers

Who Should Get This? 

The VK-6067B is an excellent choice for homes with open floor plans, such as a kitchen and living room without a wall between them. 

5. Bissell MYair Purifier 2780A: Best for Small Office

Key Features:

  • 3-stage filter 
  • Activated carbon filter cleans VOCs
  • Captures 99.9% of all particles
  • 3 modes of operation
  • Small design for home offices or bedrooms
  • Whisper quiet mode for sleeping

Designed for use in small spaces, the Bissell 2780A is a little workhorse. It has a horizontal footprint of 8” and is light and small enough to be placed on shelves or a desk corner without impacting the workspace. The 2780A uses an activated carbon filter that attracts particles that cause smells and also removes volatile organic compounds (VOCs) from the air. 

The triple-stage filtration system catches all larger airborne items and pet dander, smoke, pollen, and other allergens that make it difficult for some people to breathe. If you’re looking for a small but powerful purifier, the Bissell 2780A is an excellent choice.

The 2780A also comes with a night light that can be turned on and off. The night light makes this an excellent option to put into an infant or small child’s room (although the light is a fairly bright blue). The sleep mode is ultra-quiet, working to purify the air while you snooze.

Pros

  • Can fit under a kitchen cabinet
  • At 4.6 lbs., it is very lightweight
  • Night light option for kid’s rooms

Cons

  • Night light might be too bright for some

Who Should Get This? 

This is an excellent purchase for a home office or a small bedroom of around 100 ft2, and the night light is an excellent addition for a child’s room.

Key Features:

  • 2-stage air filtration
  • 99.9% of particles removed from the air
  • 100% ozone generation free
  • 2 optional mood light modes
  • Timer and 3 fan speeds

The Pure Enrichment Halo is a large purifier in a small package. Named “Halo” after its disc-shaped design, it filters and purifies just as much air as some of the larger purifiers in this review. Smoke, dust, pet dander, and smells are all removed without generating any ozone, which other purifiers using active filtration systems can do.

The mood lighting lets you set the lighting on either bright or low. You can turn the illumination off completely by holding the button down until the lights blink 5 times and turn them back in the same way.

The Halo removes 99.0% of all particles in the air and eliminates allergens such as pet dander to reduce allergy attacks. The purifier is small enough to place beside the lamp on a nightstand in your child’s bedroom to purify the air and provide a dim night light so that they can sleep comfortably with clean air.

Pros

  • Very small size for the air it purifies
  • 7” deep makes for a small footprint
  • Mood lights can be turned off
  • Fits nearly anywhere there is a space
  • Lower price than similar models

Cons

  • No air quality indicator

Who Should Get This? 

The PureZone Halo is an excellent purchase for someone that needs a purifier that can be placed just about anywhere in a small room and is on a budget. 

Key Features:

  • 3-part filtration system
  • Washable pre-filter captures large airborne particles
  • Activated carbon filter for smells
  • For rooms of up to 175 ft2
  • Very quiet at 17 dB 

The Blue Air 411 is a small purifier with a diameter of 8”. The small area it takes up means you can place it in any small- or medium-sized room. Blue Air designed the 411 for rooms of up to 175 ft2, which generally includes bedrooms, home offices, or enclosed living rooms and kitchens.

You have the option of changing the pre-filter color from black to blue (included) to match the colors of the room you place it in. You can also wash the filter, which reduces the costs of replacing them every few hundred hours.

Odors are removed by the activated carbon filter, whose porous properties attract and adsorb allergenic particles. The activated carbon filter also attracts and traps VOCs, making them a very effective filtration method.

Of the quiet purifiers we have reviewed here, the Blue Pure 411 is the quietest. Registering only 17dB on the lowest setting, you’ll barely notice that it is on. If you need a purifier while you sleep, this might be the one to consider.

Pros

  • Reusable pre-filter reduces operating costs
  • Removes 99% of all allergens
  • Different color pre-filters 

Cons

  • No air quality sensor
  • Expensive carbon filter replacement

Who Should Get This? 

An expensive option, the BlueAir 411 is an excellent filter for the home if you plan to move it to multiple rooms or just want guaranteed pure air anywhere you place it.

Key Features:

  • Sleep mode operates at 25 dB
  • Removes 99.97% of airborne particles 
  • Moves 5,297 ft3  of air per hour
  • Purifies rooms up to 161 ft2
  • Small size for easy placement

TaoTronics have established itself as a quality brand in the home appliance industry. Its air purifiers are top-rated by Amazon customers and for good reason. The TT-AP001 has a 3-stage filtration system that combines a pre-filter, a HEPA filter, and an activated carbon filter to remove particles and allergens from the room’s air. 

The filtration system removes 99.9% of all allergens and air impurities. If you suffer from allergies, have pets in the house, or live in an area where pollen counts are high, The TT-AP001 can clean the air in your room so that you can breathe easier. When you set the mode on the quietest setting, you may not even know that the unit is on.

Many purifiers take in air and then force it through a 1-direction outlet. The TT-AP001’s circular design collects air from 360° around the purifier and then disperses the clean air through an outlet at the top. A cone of equally distributed clean air drifts throughout the room, which lets you place the purifier anywhere.

Pros

  • Removes pet and other air odors
  • Blue light adds a pleasant ambiance

Cons

  • Replacement filters are expensive

What kind of review would this be without a Dyson product? If you simply must have the best and the most modern model of air purifier available, the Dyson Pure Hot + Cold WiFi might be the one for you. Does your room get cold during fall and winter? The Dyson has a heater function to keep you warm and prevent you from spending money on a heater as well.

The filtration system is similar to other purifiers available, using activated carbon and HEPA to remove allergens and particles. The most significant differences between other models, and this unit is the Wi-Fi option and the unit’s appearance. Dyson’s elliptical fan design disperses the purified air out into the room, in style.

The Dyson Link app gives you room air quality reports and lets you adjust the settings, only interrupting you for a few seconds. With the combined effect of a fan, air purifier, and heating controlled through your phone, this is truly a fantastic unit for your home. If you simply have to have the best, this is it.

Pros

  • Futuristic appearance is attractive
  • Small size for home office or bedrooms
  • Control the settings through the app
  • Don’t need to purchase a small heater

Cons

  • Price is very high

If you want the convenience of app control, along with important statistics about your air purifier’s performance, this hi-tech Dyson model is a great choice.

How to Choose the Best Small Air Purifier?

Affordability

Many factors influence a product’s price. The more a manufacturer produces and sells, the less they can charge for it and generate the same profit. This means for consumers to choose an air purifier, they must select one from a well-known and reputable manufacturer to get the best product for the lowest price. 

However, some of the more well-known manufacturers, such as Dyson, can charge a premium for their products based on their reputation and amount of extras they can include on a product. 

You’ll have to choose a model that offers the filtration you need (and the method you want) that meets your budget.

How Modern Purifier Filters Work

There are many different air filtration systems available. One method of filtering viruses and bacteria from air is ultraviolet light, which kills or inactivates them. Active carbon filtration is a technique that uses activated carbon to attract particles. 

An activated gram of carbon is very porous and has a vast surface area for its size. The surface area attracts the particles, adsorbing them. HEPA filters are mechanical in that they are a very fine mesh that air is forced through to filter out large particles.

You should choose a purifier that has a combination of air filtration methods. The more methods a purifier employs, the purer the air can be.

Size and Portability

An air purifier’s size is a factor that is focused on more by consumers than many other factors. We all have limits in our spaces at home for extra devices, so an air purifier needs to be small enough to be out of the way but be powerful enough to clean our air. 

For most of the rooms in our homes, the small factor air purifiers work well. However, if you have a home with an open floor plan and need an air purifier, you might need to choose one of the larger models reviewed here.

If you are on a budget and can afford only one purification device but need it in different rooms as you move around the house or office, you’ll need to consider one of the smaller models that can treat a higher square footage. Those models are more versatile and have more utility. 

Moving a purifier rated for a 100 ft2 room into a 150 ft2 room will simply result in frustration. You should choose one that can purify the air in all the places it will sit in based on its area.

Appearance

Finally, the appearance of the unit needs to match your taste. In this review, we’ve seen everything from a rectangular box to Dyson’s elliptical design. Different colors are available, as well as other patterns of fan guards. There are enough options available for you to choose an appealing appearance on your purifier, as well as functionality.

Final Verdict: Our Top Choice

When you have so many products to choose from, it can become challenging to select the one that is right for you. Understanding this, we took the features that would fit most people’s needs and found the model and design that met the most criteria.

Affordability, utility, and versatility were at the top of our list of criteria.  PureEnrichment’s PureZone 3-in-1 Air Purifier is a small air purifier that meets most people’s needs. If you’re looking for the most effective air purifier with an affordable price tag, the PureZone 3-in-1 from PureEnrichment is the air filtration system that can fit your home and office air quality needs.
