Updated: Jul 01, 2020

Clean indoor air is important as it can cause health problems in the future. Sometimes you want a portable purifier that can be compact but at the same time be able to purify the air in the room.

Some of them can remove odors, the others have an advanced filtration system for those who are too sensitive to dust.

There are 5 best portable air purifiers with the best filtration system and smart features for personal use.

Dyson DP04

The Dyson Pure Cool Purifying Desk Fan DP04 certainly looks stylish. It has plenty of features, including sensors that capture live data on the air quality in your room, and the option to control it from your smartphone via the Dyson Link app – which will even let you set up voice control via an Amazon Alexa or Echo.

Size: 8.77 x 13.85 x 27.2 inches and it is the biggest in the list.


  • removes pollens and allergens;
  • gets rid of indoor odors;
  • adjusts fan speed as needed;
  • tracks air-quality in real-time;
  • shows an air quality report;
  • works as a fan and as a purifier;
  • has an LCD screen;
  • 10 fan speeds;
  • has 3 different sensors (humidity and temperature, the particulate, the smoke sensors);
  • oscillates at 350 degrees.


The design of this Dyson air purifier is impressive. It is baseless and is easy to clean.

The Dyson DP04 can be adjusted manually thanks to the pivots of its body. So you can angle the airflow up and down without the need of its mechanized oscillation settings.

There is also a blue color option available for the Dyson DP04.


Dyson DP04 will use the best and latest air filter from this company. It is a better filter, with a 2-stage air cleaning system instead of only 1 like the predecessors: true HEPA filter and an activated carbon filter (removes household odors and gases).

You will be alerted when the filter needs to replaced.

Pros Cons
a nice bladeless design quite expensive
10 fan speeds and adjusts due to the number of particles in the air

Molekule Air Mini+

Now, Molekule has launched the Air Mini+, which has all the same features of the Air Mini (plus a few more). 

It replaces the air in a 250-square-foot room every hour.

Size: 12 in (30.48 cm) high × 8.26 in (20.98 cm) wide.


  • a particulate sensor tracks particles in the air; 
  • an automatic fan adjustment (activates in Auto-Protect mode);
  • destroys particles instead of trapping them;
  • uses a UV light;
  • it does not have a separate pre-filter, the Molekule Air Mini+ does have a hybrid pre-filter and PECO filter and a $99 per-year subscription that automatically sends you a replacement every six months;
  • can be connected to the app;
  • has 5 fan speeds;
  • has a filter replacement indicator.

What is PECO filtration?

Photo Electrochemical Oxidation (PECO), works at the molecular level to destroy pollutants. It breaks down VOCs, bacteria, mold, viruses, allergens, and other pollutants at a molecular level when activated by light.

Pros Cons
small size the fan is still loud at higher speeds

The Levoit LV-H132 serves as a momentous device in the story of compact air purifiers. It uses a new design language for air purifiers. The machine makes about 26 dB of noise. You can turn the lights off if needed.

The size of the device: 8.5 x 8.5 x 14.5 inches.

The most efficient coverage: 129 ft² (12 m²).


  • removes odors and pollens;
  • has night mode;
  • has 5 buttons to control the machine.


Instead of the usual solid square-shaped design as in Levoit LV-PUR131, the Levoit LV-H132 is cylinder-shaped, with a pre-filter right at the bottom of this air purifier. The air will flow from the bottom, through many air filters and get out from the top of Levoit LV-H132. This bottom-to-top airflow concept is extremely popular at the moment, all thanks to this Levoit LV-H132.

Levoit LV-H132 comes with 2 color modifications: black and white. Also, there are 5 buttons on the top to control the purifier.


The purifier has a three-step filtration system: pre-filter that catches big particles, the true HEPA filter removes allergens and pollens and activated carbon filter which gets rid of household odors.

There is a built-in replacement indicator that tells when you need to replace the filter.

Pros Cons

small cylinder shape body  
a built-in night light that is dimmable

 IQAir Atem Desk Personal Air Purifier

If you’re looking for a high-quality desk air purifier, the IQAir Atem might be the best device for you. When it comes to a desk air purifier, you want one that works hard to remove airborne pollutants and harmful elements from your indoor space. It can also be used as a car or travel purifier.

The purifier can be connected to the app to control the IQAir.

The unit's size: 11.5 x 3.1 x 11.5 inches.


  • proximity sensor tells the Atem to turn off when the user walks away;
  • has 3 fan speeds;
  • WiFi and Bluetooth enabled;
  • app control;
  • intelligent filter monitoring;
  • has a sensor button;
  • quiet when operating.


This desk air purifier is shaped like a disc with a clear wing-shaped piece protruding from the top. That part is called the PureJet diffuser and it’s where clean is delivered out of the device. 

The Sensor button is located on the side at the center of the disc. You won’t see a physical button because it’s a touch-sensitive area. The Sensor button responds to your touch to turn the unit on/off and increase/decrease the fan speed.

This personal air purifier also comes with a stand to ensure it stays upright on your desk or other surfaces.


The company chose to include their most advanced filter in a smaller size:

HyperHEPA Filter. Manufacturers of ordinary air filtration systems claim that their systems filter particles larger than 0.3 microns. IQAir's HyperHEPA filtration is proven and certified to filter at least 99% of all particles down to 0.003 microns - the smallest that exists.

The only things the IQAir Atem can’t remove are odors and chemical vapors in the air.

Pros Cons
top-notch performance no carbon filter
advanced filtration technology  
beautiful design  
very quiet  
lowest power consumption  
5-year warranty
