Levoit H133 Design

The Levoit LV-H133 air purifier is a tall air purifier that has a round body style and matte white finish.

The base of the unit has perforations that allow for air to be sucked into the purifier. From there, an internal motor and HEPA filtration system treats the air and sends it out of the purifier out the radial grill on top.

The 360° opening provides a wide outlet for air to flow freely. In addition, this air purifier can treat up to 538 sf. of living space and offers easy controls using a touch display with LED lighting.

The LED light color changes as the indoor quality changes, making it easy to pick up on the changes in the air.

• Blue = Very good air quality
• Green = Good air quality
• Yellow = Moderate air quality
• Red = Poor air quality

This Levoit model comes in two finishes: black or white.

The Filters

This Levoit air purifier uses three stages of filtration for the best performance, including:

1. Fine pre-filter: captures larger particles like dust, lint, or fibers
2. HEPA filter: captures particles as small as 0.3 microns
3. Activated carbon filter: for odors like smoke, food, or pets

The combination of these filters helps to ensure that all of the air is effectively treated and only clean air passes through.

The Controls

Controls for the Levoit LV-H133 are located all on the top of the air purifier. There is a power button right in the center with the following buttons on the perimeter of the circle:

• Adjust fan speed
• Timer (1-12 hours)
• Sleep mode
• Display off
• Filter change indicator
• Auto mode

The Levoit LV-H133 cannot be controlled using your smartphone. However, if smartphone control is an important feature they do offer a purifier with wifi connectivity.

Performance

So regarding performance, how did the Levoit H133 stack up against the other heavy-hitters on the market, like Dyson or Rabbit Air?

Testing Series

Our testing consisted of setting up the Levoit in a large bedroom in my home. A baseline measurement of the indoor air quality was established and then we ran the purifier on high for 1 hour and took another set of measurements.

For accurate measurements, we used the Temtop LKC-1000S+ professional air quality detector.

The difference between the baseline and post-run data gives a good look into the overall performance of the purifier.

Good vs. Bad Air Quality

Below, we’ve included information on the testing criteria and what defines good vs. bad air quality.

What were the results?

Within 1 hour the Levoit H133 removed 96% of air particulates from the room we tested in.

Levoit improved PM2.5 air quality by 96%. Overall, these are exceptional results and really a testament to the overall build quality, design, and performance of this Levoit air purifier.

For the best results, Levoit recommends the following settings:

• 1 Speed: ACH of 5 over 100 sq ft.
• 2 Speed: ACH of 4.5 over 160 sq ft.
• 3 Speed: ACH of 4 over 538 sq ft.

How loud is the Levoit?

According to the manufacturer, the Levoit LV-H133 can range from 25-52 dB. The 52 dB is documented on high speed while the 25 dB is documented on sleep mode.

For comparison, breathing is rated around 10 dB and a library would be around 40 db.

Setup & Usability

Setup of the Levoit H133 is simple and quick, straight out of the box.

1. First, unbox the purifier and remove all excess packaging.
2. To remove the shell from the base, twist it counterclockwise.
3. Remove the plastic bag of the filter before running the air purifier.
4. Twist the shell to lock it in place.

To start a cycle, you can simply press the “on” button and select a fan speed or you can set it to Auto Mode. For instance, if you’re leaving and want the Levoit to self-adjust, Auto Mode would be a great option.

On auto mode, the sensors can detect indoor air quality and adjust fan speed as needed.

Maintenance

To keep the air purifier running at its peak performance, proper maintenance is an important step.

To that end, maintenance of the Levoit LV-H133 includes:

1. Wipe down the air intake and outlet grills with a dry, lint-free cloth
2. Replacing the filters as needed, every 6-8 months as recommended by the manufacturer

The Filter Change Indicator also lights up to let you know it’s about time to put in fresh filters. Filters can be purchased directly from Levoit or via a third-party website like Amazon.
