Levoit IV-h133 review – A Smart and Efficient Air purifier

A perfect air purifier is one that filters both particulates and gaseous pollutants from the air without releasing ozone or other harmful byproducts. Levoit air purifiers are the safest on the market. Because they only use mechanical filters in their air purifiers and don’t use any electronic filtrations. Levoit LV-H133 is a 23.6-inch tall cylindrical-shaped air purifier that has a complimentary 3-in-1 filter with a built-in dust sensor suitable for a 400 sq ft room. In this Levoit LV-H133 review, we discuss its features, operating costs, pros, and cons. We also include a comparison between the Levoit Tower LV-H133 and LV-H134 air purifiers.

Effective 3-in-1 filter:

The purifier has a three-stage filtration system. They include a pre-filter, a True HEPA filter, and an activated carbon filter in a 3-in-1 cartridge. The preliminary net filter captures large particles such as hair, lint, pet fur, dust, and pet dander. After the pre-filter, you have the H13-grade true HEPA filter. With a 99.97% efficiency rating, this filter traps and removes particles as small as 0.3 microns from the air. They include pollen, fine dust, smoke residue, and many others. Lastly, we have an activated carbon filter. Composed of granular activated carbon, the filter absorbs cooking odors, household odors, cigarette smoke, and VOCs.All three filters come as a single unit.


Design & Interface:

Physically speaking, the LV-H133 is pretty standard in both size and appearance. It uses a cylindrical build that measures around 26.1 x 16 x 15.5, and it basically looks like a skinny trashcan with a fancy light on top. That light is a LED display that functions as a full touchscreen. So from the display, it’s possible to review the quality of the air in the room or to make changes to how you want the LV-H133 to operate. We’ll look more closely at the various modes of operation a little bit later, but this is essentially where you’ll set or alter your operation timers.

Touch-based Controls:

The air purifier has touch-based controls. Every mode and button is intuitive. Not only that. The beautiful interface makes it appealing. To change a setting or run a function, press the button once. Let’s start with the filter indicator. This button illuminates when it’s time to replace the filter. This should happen after 6-8 months since you last installed a new filter. If you replace the filter, press the button for three seconds to reset it. After the filter indicator, you have the timer button. It allows you to set the timer up to 12 hours in any mode. If you don’t want the purifier to operate all the time, set the timer. You have the fan speed button that allows you to select low, medium, and high fan speeds. To choose low fan speed, press once; for medium speed, press twice; and for high fan speed, press three times. To confirm the fan speed selected, check the speed indicator.

Room coverage:

It has a 538feet bigger square for a large Air purifier levoit. Without any worry, you can use this air purifier in a household in the us and in other countries. You should check the blue pure 121 (with a good quality fan and 620 square feet of room coverage)if you did” not satisfy. The CADR of Levoit LV-H133 is 274 Dust/ 285 Smoke/ 287 Pollen (cfm). It tells exactly how fast your air purifier can clean your room, and with that number, Levoit LV-H133 will deal with a large room of 538 square feet much slower. With that decent fan power, Levoit LV-H133 can’t compare with the high CADR of Blue Pure 121 or Honeywell HPA300.


According to the manufacturer, the levoit 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.

Additional features :

 This company improves its Smart Sensor to help detect real-time air quality in only 30 seconds. Moreover, this Smart Sensor will automatically adjust the fan power to fit the surrounding environmentThe Sleep Mode is my most used function. With a single mode, this Levoit LV-H133 will automatically switch to the lowest fan speed, which is perfect for my nighttime. The final basic feature you can get from this Levoit LV-H133 is an electrical LED indicator for filter replacement. After each time you change your filter, don’t forget to reset the indicator. . This filter is intended to capture big chunks of particles that are trapped in the air. In other words, it’s good for capturing mold spores, bits of pollen, and dust.
