The air we breathe contains a lot of small impurities floating around. Some of these impurities like pet hair and dust are large enough to be seen, but the majority of them are hard to see with the naked eye because they are very small.

From triggering allergies and causing other health problems to plain discomfort, these impurities make our lives very miserable. This is why an air purifier is an important addition to any home. It is a simple device that is easy to operate and it makes all the difference.

In this article, we are going to compare three popular air purifiers from Levoit. These are the Levoit LV-H133, the Levoit LV-H134, and the Levoit LV-H135. These three devices use a 100% ozone free process that cleans the air without releasing any gases that are harmful to the environment.

Let’s dig in to find out exactly what each model brings to the table.


The performance of any air purifier will be determined to a great extent by the quality of filtration that it’s able to achieve. It’s also important that the air purifier can clean a wide range of contaminants from the air. Let’s see how the filters on these three air purifiers perform.

Levoit LV-H134

Levoit LV-H133
This air purifier comes with a 360-degree filter that takes in air from all sides to ensure maximum airflow and as a result, faster air purification. According to Levoit, this design together with their cyclone technology enables the device to purify the air 40% faster than most other competitors.

The filter in use is a three-stage high-efficiency filter that will tackle most of the impurities you will find the typical home or office. The first stage is a fine preliminary filter that will catch large particles like lint, pet hair and other fibers that might be present in the air.

The second stage is the true HEPA filter that goes deeper in purifying the air. It will catch the finest of particles that might have passed through the preliminary filter. These include dust mites, pollen, airborne bacteria and dander from pets. This filter will capture up to 99.97% of small particles up to 0.3 microns.

The final stage is an activated carbon filter that will absorb odors such as cigarette smoke, pet odors and cooking smells from the air before it is finally released back to the room.

Levoit LV-H134
The Levoit LV-H134 air purifier also comes with a 360-degree filter and cyclone technology just like the LV-H133, but everything is improved thanks to the 360-degree air intake. This enables the air purifier to purify the air up to 50% faster than other similar air purifiers.

Levoit LV-H135

The filter in use is also a three-stage high-efficiency filter that can remove up to 99.97% of small airborne impurities up to 0.3 microns. The three stages include a fine preliminary filter, a true HEPA filter, and an activated carbon filter just like in the LV-H133.

To help you know how clean or dirty the air in your room is, this air purifier comes with an accurate Laser Sensor that will scan the air so that it can report the exact number of particles in less than 30 seconds so that you get quick and accurate feedback on the air quality in the room.

Levoit LV-H135
Unlike the other two that come in a cylindrical shape, this one comes with a rectangular shape. However, the filter inside is a cylindrical filter that is very similar to the filters on the other two air purifiers when it comes to capabilities.

Levoit H133 Air Purifie

This filter is also a three-stage high-efficiency filter that has a fine preliminary layer for the larger particles, a true HEPA layer for the fine particles and an activated carbon layer for capturing the odors.

Like the LV-H134, this air purifier also comes with a 360-degree air intake that works together with the cylindrical filter to purify the air up to 40% faster than similar air purifiers.

Room Coverage

Air purifiers are not all born the same. Some can purify the air in larger rooms than others. Let’s see how these three perform.

Levoit LV-H133
The Levoit LV-H133 air purifier falls between the other two when it comes to room coverage. It is, therefore, the perfect compromise when you want high performance without having to spend too much.

Levoit LV-H134 Air Purifie

In square feet, this air purifier will cover areas as large as 538 square feet, making it ideal for large rooms and offices. In addition to the ability to cover large rooms, this air purifier does the job fast thanks to the design of the tower and air outlet that’s inspired by aircraft jet engines.

Levoit LV-H134
When it comes to room coverage, this is the most capable air purifier of the three that we are comparing today. The main body and the outlet have also been designed like an aircraft engine to ensure that the purified air gets to all parts of the room faster than conventional designs.

Levoit LV-H135 Air Purifier

This air purifier can comfortably purify the air in rooms as big as 710 square feet. It is the model to go for if the other two are too small for your home. The smart sensor makes it even faster in purifying the air because it will quickly get the air quality status in the room and get to work.

Levoit LV-H135
When it comes to room coverage, this is the least powerful of the three because it can only clean up to 463 square foot rooms. However, this is not to mean that you can only use it in small rooms. This air purifier has been made for use in large rooms. It’s only that it has the lowest coverage when compared to the other two models.

You will be able to quickly and effectively purify the air in rooms as large as 463 square feet using this air purifier.

Controls and Purification Modes

Different situations have different air purification requirements and an air purifier should come equipped with the necessary tools to meet all these requirements. For example, when you are asleep, you want to enjoy clean air without the discomfort of bright lighting from the display or loud fan noises. Here, things are quite standard across the three air purifiers.

If you prefer that the machines take care of everything automatically, they come with Auto Mode that will monitor the air quality in your home and make adjustments to the settings automatically to ensure that air quality is maintained at its best with no need for your input.

When you need to rest, you want tranquility and peace of mind. These air purifiers have you covered because they come with Sleep Mode that will clean the air while maintaining the lowest noise levels. You can also turn off the display lights to ensure that you only get clean air and nothing else from the machine.

Another nifty feature is the 1-12 hour timer that you can use to schedule to see to it that you find your home with clean air when you come home while at the same time lowering the energy consumption of the machine because it won’t have to run around the clock.

These three air purifiers are amazing devices that will do a great job of cleaning the air in your home. They have been designed to catch most of the common impurities in households hence they will be a great investment in your home. The main difference between the three models is the room coverage. The LV-H134 will work on the largest rooms and the LV-H135 on the smallest. However, the Levoit LV-H135 comes with casters so it is the best choice if portability is an important consideration for you.
