Levoit is a fully certified and trusted air purifier brand having over 3 million customers worldwide. Designed in California, the Levoit air purifiers come with a modern, minimalist aesthetic. These purifiers have also proven to be environmentally-friendly and come with a solid warranty.

This guide explores some of the best Levoit air purifiers currently available.

Buying Guide

If you can’t differentiate between various Levoit air purifiers or have no idea as to how to choose one, here are a few factors you should consider when buying an air purifier. These will inform you about the most significant aspects of an air purifier and will help you with your decision.

Room Coverage

This property refers to the size of the room an air purifier can handle. This is among the first features you need to consider when getting your Levoit air purifier. Our guide includes purifiers for small, medium, and large spaces.

Many air purifiers meant for small rooms can be used in medium-sized rooms as well. A purifier for a large room can easily and quickly filter the air in a small or medium room. However, using a small room’s air purifier for a large room will drastically bring down the ACH (explained further in the guide).

Thus, if you have a small room only, then get an air purifier with a room coverage of around 161 ft2. If you have a mix of small and large rooms, it is better to buy a purifier for a large room with a room coverage close to 500-600 ft2.


Levoit air purifiers are installed with 3-stage filtration where 3 high-quality filters remove 99.97% of pollutants from the air. These 3 filters are:

  • Pre-Filter: this is the 1st stage of filtration where large, solid particles, like pet dander, hair, lint, and dust mites are captured. This filter is often made from polyester.
  • True HEPA Filter: this filter captures very small particles and germs like viruses and allergens.
  • Activated Carbon Filter: the air, now free of solid particulate matter, passes through this final filter where odors and smoke, etc. are absorbed and biologically decomposed.

After this, the air is clean of any airborne pollutants and toxins, and completely fresh to inhale safely.

Levoit's high tech filtration system locks in any allergens in the air


Your air purifier should be powerful enough so that the motor quickly rotates the fan in order to capture air for filtering and then release the filtered air back. Especially for a purifier meant for large rooms, the power should be high. Nonetheless, with Levoit air purifiers, power is not an issue as its machines come with powerful motors and fans.


This feature needs to be carefully analyzed because a purifier that creates high noise levels, especially at night, is likely to disrupt your sleep. Look for an air purifier that makes 20-30 dB noise at its lowest fan speed. Most Levoit air purifiers have a ‘silent’ or ‘night’ mode which creates 26-27 dB noise.

The sound level depends upon the speed of the fan so you can adjust the speed accordingly at night or whenever you want a quiet environment. Even if the highest noise level is 50-60 dB, you can lower the speed of the fan to make your purifier run silently.


CADR is short for Clean Air Delivery Rate and is measured in cubic feet per minute (CFM). It tells gives an estimate of the volume of a particular-sized airborne material removed from the air within a minute. The CADR rate, thus, is different for every pollutant.

For smoke and pollen, a CADR rating of 450 CFM is the highest whereas, for dust, the best CADR rating goes to 400 CFM.


ACH refers to Air Changes per Hour and it tells how many times an air purifier will filter (change) the air in your room within an hour. An ACH of 4, for instance, would mean that the purifier filters air completely every 15 minutes. Different air purifiers come with different ACHs.

Air purifiers for large rooms usually have a lower ACH than those for small rooms. Either way, try to find a machine with a high ACH so that fresh air is constantly circulating your room.

Additional Features

You will easily find a high-quality Levoit air purifier satisfying the above requirements. However, if you still cannot make a decision, look for additional features provided by the machine such as these.

  • Remote control using a voice-enabled smart device.
  • Options for setting times and schedules to automatically turn the air purifier on or off.
  • Multiple options for the speed of the fan, such as slow, medium, and fast.
  • Aromatherapy, which allows you to put essential oils in the purifier to spread fragrances of your choice in the room.

The Best Levoit Air Purifier Models Compared

Here are our top picks for Levoit air purifiers as we believe each of these machines brings something valuable to the table for getting fresh air:

grey Levoit core 300 Air Purifier

Best for Small Spaces

Levoit Core 300 Air Purifier

Device Dimensions8.7 x 8.7 x 16.25 in
Clean Air Delivery Rate135+ CFM
Noise Level24 dB

This air purifier is a best seller in Levoit’s catalog and comes with glowing reviews. Known for its efficiency, it has won at the Contemporary Good Design 2019.

This highly affordable product is most suitable for small areas such as a bedroom, a dorm room, or an enclosed office space as its coverage is 219 ft². In such a space, it can filter the air 5 times per hour. Its H13 True HEPA filter traps 99.97% airborne particles, including fine particulate even as tiny as 0.3 microns. This includes contaminants such as dust, smoke, odors, fumes, pollen, pet dander and pet hair, and volatile organic compounds (VOCs). Some of these are trapped using its activated carbon filter while the pre-filter traps large pollutants in order to protect the H13 true HEPA filter.

Being highly efficient and CARB certified, its CADR for smoke is 141 CFM, for dust it rests at 140 CFM, and for pollen, it goes up to 145 CFM.

With this air purifier, you have the option to choose among 3 specialized replacement filters. There is no best filter among these 3 as each serves a different purpose and caters to a particular need.

  1. True HEPA 3-Stage Pet Allergy Filter is designed for pet odors and allergies.
  2. True HEPA 3-Stage Toxin Absorber Filter is customized to neutralize airborne toxins such as smog and smoke.
  3. True HEPA 3-Stage Original Filter is for common use to capture everyday pollutants and odors.

One complaint that is common with the use of an air purifier is the high noise level. However, for the Levoit Core 300 purifier, the machine operates nearly soundlessly with just 24 dB at sleep mode. This is enabled by its QuietKEAP technology which uses an internal shock pad to absorb noise to help you sleep peacefully without being disturbed by any noise. On the same note, you also have the option to turn off the display light if you prefer to sleep in complete darkness.

If you hesitate to buy an air purifier due to its impact on the environment, you can rest assured with this option from Levoit because it does not use UV/ion light since this method can produce Ozone pollution. Lastly, the compact shape of this purifier makes it very portable.

Levoit Core P350 Pet Air Purifier for pet allergens

Best for Pet Owners

Levoit Core P350 Pet Air Purifier

Device Dimensions8.7 x 8.7 x 14.2 inches
Clean Air Delivery Rate141 CFM
Noise Level24 dB

For all those looking for a healthier environment for themselves and their pets, the Levoit Core P350 is marketed for pet owners and is arguably the best choice of a Levoit air purifier if you have pets in your home. Available in a light shade of gray, this air purifier measures 8.7 x 8.7 x 14.2 inches.

Due to its compact size, this machine is fit for a small to a medium-sized room since it has a range of 219 ft2. Its Vortexair Technology offers a CADR of 240 m3/h which is considered a high CADR. The number of times it filters the air within an hour depends upon the size of the room. For example, the air in a 273 ft2 area will be filtered 4 times in an hour but with a 547 ft2 area it will only be filtered twice an hour.

Note that the H13-grade TRUE HEPA filter does not completely eliminate airborne pollutants; it only reduces their spread significantly. These include pet dander, smoke, dust mites, pollen, and mold. This filter uses the ARC formula where high-grade Modified Activated Carbon is coupled with AirReComposition. This removes pollutants by first absorbing, then biologically decomposing, and finally locking them in. In case you need to change it, you will be able to easily find genuine replacements for the customized filter with the ARC formula.

This model also incorporates Levoit’s famous QuietKEAP technology which enables its purifiers to work with minimum noise. Levoit’s P350 keeps noise levels to as low as 24 dB when its Sleep Mode is activated. Along with this, to facilitate your sleep, you can turn off the display lights and adjust the speed of the fan accordingly with the low, medium, and high speed options. Also, before going to sleep, you can set the timer for 2, 4, 6, or 8 hours.

If you are wondering how exactly this air purifier will be beneficial for your pet, these are a few of your pet’s allergic symptoms that can be relieved: sinuses, coughing, sneezing, and stuffy nose. And if you’re worried about your playful pet tampering with the controls on the machine, the Levoit P350 has an interesting pet lock that will prevent this from happening.

Similar to most of the Levoit air purifiers with H13 True HEPA filter, this one also captures 99.97% of airborne pollutants – even as minuscule as 0.3 microns, including dust, mites, allergens, and pet dander. This is done by the use of:

  • Fine Preliminary Filter for capturing large particles like pet fur
  • True HEPA filter for fine particles like pollen and dust mites
  • High-Efficiency Activated Carbon Filter for odors and smoke

Some of the advanced features of this machine include its ability to give real-time air quality updates – such as ‘very good’, ‘good’, ‘moderate’, or ‘bad’ – and an adjustable indicator display. Many Levoit air purifier models offer the option to just turn off the light instead of adjusting its brightness. Its wheeled design makes it extremely convenient to move it from one room to another on its rolling base. The machine also includes a filter indicator which lets you know when the filter needs to be checked.

Apart from these, this air purifier offers the usual benefits associated with Levoit’s air purifiers: approximately 26 dB noise at sleep mode, timer function, and 3 different options for fan speed. In fact, the machine is quiet even at its highest fan speed. There are also easily-available filter replacements for this machine and on average, the filter needs to be replaced every 6 to 8 months.

Cleaning this Levoit air purifier with a dry cloth will suffice and the filter can be brushed or vacuumed, but not washed as it poses safety threats.

If you’re looking for such an air purifier, the LV-H128 fits the bill.

Measuring 6.7 x 6.7 x 10.4 inches, this machine is lighter in weight than most other Levoit air purifiers – it weighs 3.3 pounds only.
