The Levoit LV-H134 is a great device, with plenty of cutting-edge features. However, the missing piece for it to be truly top tier – is a smart app option!

The review on its sibling model, the Core 400S proves just how much you could get out of this extra feature; an array of new possibilities right at your fingertips.

Air Quality Sensor and Indicator

The air quality sensor is my go-to feature on this device – and for good reason! It’s a laser particle counter which allows you to detect PM2.5 particles in real time, making it an invaluable asset when monitoring your environment.

A numerical value representing PM2.5 and a colored ring that encircles the entire display is used to deliver accurate, real-time air quality information.

  • Red = Poor air quality
  • Orange = Moderate air quality
  • Green = Good air quality
  • Blue = Excellent air quality

A special sensor is mounted on the rear of this device, and even more impressive is how it works in conjunction with other features.

Auto Mode

For total ease of use and convenience, Auto Mode is an excellent choice with your air quality sensor.

When engaged, the device will constantly assess the condition of the current air quality, automatically adjusting its fan speed as needed.

In order to ensure that the air quality in your room is of optimal standard, this device has been designed with an Auto Mode feature.

Depending on how polluted or clean the air already is in your environment, it will switch between High, LOW, and Sleep Modes accordingly; for a comprehensive summary of how exactly these modes function together consult the table below.

Sleep Mode

Sleep Mode is the ideal choice if you would like your air purifier to operate with minimal noise in a bedroom or other room. This feature allows for silent operation, providing maximum comfort and peace of mind.

Activate the sleep mode on your air purifier for an undisturbed night’s rest, and it will automatically reduce all LED indicators to off as well as adjust the fan speed to its lowest level.


The Levoit LV-H134 air purifier is equipped with a timer for ultimate convenience; you can set the machine to shut off after 1-12 hours of runtime. It’s as simple as that!

No need to worry about accidentally leaving it on or having it run all night – just set your desired time and let the timer do its job.

Filter Reset Indicator

The Levoit LV-H134 air purifier is equipped with a filter reset indicator, allowing you to easily keep track of the filter’s lifespan and when it needs to be replaced.

Using the control panel, you can quickly identify when it’s time to replace your filter with Levoit’s convenient built-in indicator light. With this advanced feature at your fingertips, gone are the days of having to manually monitor and guess when a new filter is needed – Levoit does it for you!

This indicator effectively eliminates the guesswork associated with manual assessment, giving you peace of mind that your device will always be working at its optimal performance.

Display Off

This advantageous option is incredibly useful if you are in a dimly lit room and need to avoid being disturbed by the glowing LED indicators, as it turns off all of them with only one touch!

The Levoit LV-H134 is equipped with a high-tech air purification system that consists of an extra-large filter. The cylindrical design has a hollow center and the 3-stage filtration process guarantees you top-notch clean, breathable air in your home or office!

Keep your home healthy and protect the True HEPA filter with regular maintenance of the pre-filter. All it takes is a simple vacuum twice a month to prevent large particles – such as dust, dirt, or pet hair – from reaching and restricting its functionality!

True HEPA Filter

The second, and most essential, filtering stage of this machine is the H13 True HEPA filter. It guarantees that at least 99.97% of airborne particles with dimensions as small as 0.3 micrometers (µm) are eliminated from the environment around you!

Activated Carbon Filter

The Levoit LV-H134 air purifier is no ordinary machine. Its activated carbon pellet filter offers superior filtration technology, effectively eliminating odors, smoke, and vapors from the atmosphere – as well as gas compounds like formaldehyde, benzene, hydrogen sulfide, and VOCs. So you can breathe easy knowing your living space will stay clean!

Levoit LV-H134 Auto Replacement Filter


The LV-H134 produces a whopping 70.3 dBA of sound at max speed – much louder than the Blueair 211+, its major competitor. After comparing both air purifiers, I found that the performance and noise level of the engine in Blueair was more favorable to me.

Not only is the Levoit LV-H134 good at air purification but it also excels on noise tests, ranging from a very quiet 41.8 dBA in sleep mode to silent speeds with all settings enabled.

Speed Value (dBA)

Sleep Mode 41.8 dBA

Low Mode 45.7 dBA

Medium Mode 56.4 dBA

High Mode 70.3 dBA


For spaces of up to 492 sq. ft., the LV-H134 is ideal, making it suitable for larger bedrooms or living rooms. This powerful machine can filter through 4.8x its volume in just one hour – an impressive feat!

After using the LV-H134 for an extended period of time, I can confidently say that it has been beyond satisfactory when it comes to its smoke and pollen filtration capabilities as well as absorbing cooking odors and eliminating dust.

560 sq . ft. Room Test

In just one hour of operation at its maximum capacity, the Levoit LV-H134 astonishingly improved air quality to a remarkable 94%, an extraordinary accomplishment for such a small area.

This assessment truly put the Levoit to the test, where it was able to reduce a 145 Air Quality Index (AQI) down to an astonishingly low 9!

The high air volume and superior filters are certainly key players in its success. I can confidently say that this appliance performs better than any other on the market today.


The Levoit LV-H134 is a surprisingly power-efficient device, considering its impressive airflow. Featuring an engine of only 45W, it’s more than capable enough to last the entire day at maximum speed without breaking your wallet!

In fact, if you were to run this unit for 24 hours every day for one month straight, your electricity bill would increase by merely $4.4 – a small cost that speaks volumes about the quality and efficiency of this exceptional machine.

Speed Power Usage (W)

Standby 0.3W

Sleep Mode 3.1W

Low Mode 6.7W
