Levoit LV-H134 Air Purifier Review & Comparison

If you’re looking for a simple yet stylish air purifier that’s efficient enough to use in the biggest room of your house, you’ve found it. The H134 model by Levoit is a tall tower with soft lines that boasts an incredibly high CADR in rooms well over 500 square feet. It comes with features such as two-way particle readout, a quiet three-speed fan and an energy-saving timer.

A Contemporary Tower

The Levoit H134 is a contemporary, cone-shaped tower. Rounded edges and a flat top give the solid white air purifier a clean, suits-any-space look. Since its base measures 16.5 inches wide and its height reaches 32 inches, the H134 is best suited for floor placement. While 28 pounds of weight put the air purifier on the heavy side, a set of four casters makes it feel much lighter when you move it.

One Three-Layered Filter

Inside the H134, there’s one large cylindrical filter with three layers. The pre-filtration layer prevents large allergens from impeding the efficiency of the second layer – a true-HEPA media. The other layer is made of activated carbon, which rids the air of odors and irritants. By detaching the purifier’s back cover, you can quickly access the filtration unit for biannual changes.

Four-Sided Air Intake

Levoit’s H134 achieves a clean air delivery rate of 312 cubic feet per minute in expansive rooms up to 710 square feet. One contributor to its high CADR rating is the intake/outlet system. The intake consists of one inlet on each of the tower’s four sides, allowing the purifier to collect a lot of dirty air. On top of the purifier, there’s a cyclone-style outlet that rapidly pushes and evenly delivers clean air.

Two Particle Readouts

An air quality sensor isn’t exclusive Levoit technology, but it’s rare to see an air purifier that shows the air quality in two different ways. The laser sensor detects particles as small as 2.5 microns within a radius of 1 cubic meter. Within 30 seconds of measuring the particle volume, the sensor sends data to the control panel where you can view the current indoor air quality on a numerical counter and a color-coded ring.

Three Fan Speeds

The brushless fan gives you three quiet fan speeds from which to choose. On the lowest speed, the 32-decibel level is barely audible. On the highest speed, the 54-decibel sound makes for soothing background noise. Since the H134 air purifier has an air quality sensor, you can set the purifier to auto mode for automatic fan adjustment. Sleep mode is another option. On sleep mode, the air purifier decreases the fan to its lowest speed.

A 12-Hour Timer

Although the Levoit H-124 only consumes 45 watts of electricity, the 12-hour timer lets you save even more energy. Unlike most air purifiers’ timers, the H134’s timer doesn’t give you a couple of pre-set intervals to choose. Instead, you can set the timer anywhere from 1 to 12 hours, and you can use this function alongside any auto or manual fan selection.

One LED Control Panel

On top of the H134, there’s a round LED control panel loaded with sleek touch buttons. You can set and view the timer on a countdown clock, and you can see the air quality in real time. There are also indicators that tell you when the timer is activated and if the filter needs to be changed. If you’re light sensitive, you can turn off the LED bulb with a single tap.

Superior Large-Room Air Purification

From the filter and intake/outlets to the CADR and the control panel, it’s easy to see why the Levoit H134 is a premium large-room air purifier. However, Levoit and other manufacturers make more great air purifiers. Therefore, we decided to compare the H134 to three other Levoit models as well as an air purifier from one of Levoit’s competitors – Coway.

Levoit LV-H134 vs. Levoit LV-H133

These two Levoit air purifiers share many of the same useful features, including a color-coded air quality indicator, a touch control panel, and three-part cylindrical filter. Each model has a cyclonic air outlet and contains a three-speed fan that’s driven by a quiet brushless motor. Functions like the 12-hour timer, auto fan mode and LED toggle give the H134 and the H133 premium status.

Levoit LV-H134 vs. Levoit LV-H133

However, the H134’s advantage is its ability to cover over 170 square feet more space than the H133. The H134 air purifier’s CADR rating outshines that of the H133 by 77 cfm, partly due to having twice the number of inlets than the H133. The Levoit H134 model is also equipped with a numerical particle readout and transport wheels, both of which are absent on the H133.

What the Levoit H133 lacks in coverage area it makes up for in sound level, energy consumption and overall size. On its lowest fan speed, the H133 is 7 decibels quieter than the H134. The H133 also draws 12 fewer watts. The concave H133 tower is lighter, weighing 21 pounds to the H134’s 28 pounds. While it doesn’t have wheels, its smaller size of 26 by 16 inches makes the H133 easier to lift.

Levoit LV-H133

Levoit LV-H134 vs. Levoit LV-H132

The Levoit H134 and the Levoit H132 both have long-lasting filtration media and three efficient fan speeds. Each model provides three levels of filtration, including a pre-filter, a genuine HEPA filter and a carbon filter, and they both have a filter-change indicator on their respective touch LED control panels. With fully surrounding inlets, it’s no wonder that the H134 has a 312 cfm CADR and the H132 can circulate the room’s air four times per hour.

Levoit LV-H134 vs. Levoit LV-H132

Instead of a two-piece filter like the H132, all three of the H134’s filters are consolidated into one unit, and you don’t have to flip the H134 over to change the filter. The H134 also has a cyclone outlet and an air quality indicator. Other benefits of the H134 include a more user-friendly control panel, a timer, an auto mode and 581 additional square feet of coverage.

No matter the fan speed of the cylindrical H132, the H134’s corresponding speed is always louder. The H132 also consumes 20 fewer watts than the H134. Since the H134 weighs four times as much and measures twice the size of the H132, the H132 is much easier to move. Plus, the black-banded H132 has not only an LED-off function but also a two-level nightlight feature.

Levoit LV-H134 vs. Levoit LV-PUR131

Both the H134 and the PUR131 are two of Levoit’s top-tier air purifiers. They feature an LED control panel with touch-only buttons, three-stage filtration and a color-coded air quality indicator. A rear-access panel makes filter changes a breeze, and auto mode offers a convenient alternative to the three manual fan speeds. You also get the benefit of a sleep mode, a 12-hour timer with a display and an LED-off function.

Levoit LV-H134 vs. Levoit LV-PUR131

The H134’s quadruple-sided intake and a cyclonic outlet allow for a 177 higher CARD rating than the PUR131’s three-sided inlet and single horizontal grille can accomplish. You can also use the H134 in rooms more than twice the size that the PUR131 can handle. As opposed to a three-piece unit, filter changes for the H134 are more streamlined thanks to its all-in-one filter. Levoit also added a numerical particle readout and rolling casters to the H134.

Although it doesn’t have any wheels, the rectangular PUR131 does have an integrated handle to help you lift and tote it. If noise is a crucial buying factor for you, the PUR131’s lowest fan speed is 5 decibels quieter. This air purifier doesn’t draw as much electricity when in use either. It’s also 17 pounds lighter than the H134.

Levoit LV-H134 vs. Coway AP-1512HH

Levoit and Coway made a few similar choices with the H134 and the 1512HH. Both air purifiers have a true-HEPA filter, an activated carbon filter and a pre-filter. Neither model gets louder than 54 decibels even on the fastest of their three speeds. Each one also has a particle sensor that displays colorized readouts, an auto-fan speed and a filter-replacement indicator.

Levoit LV-H134 vs. Coway AP-1512HH

The Levoit model has a higher CADR and covers two times the number of square feet. There are air intakes on four sides instead of just two, and it has the desirable cyclone-style outlet. Its 12-hour timer is customizable unlike the Coway’s 8-hour interval timer. The Levoit’s control panel doesn’t have any push buttons; there is only one filter piece instead of three, and its energy consumption is 32 watts less than the Coway purifier.

Filters are easier to reach via the Coway’s front panel. While it doesn’t offer a numerical particle counter, the Coway purifier does let you change the sensitivity of the sensor. The squared Coway air purifier is 15 pounds lighter, 8 decibels quieter and a lot smaller. Coway even includes a few extra features not found on the Levoit H134, such as an ionizer and fan-stopping eco mode.

Air Recommended Air Purifiers

Our Pick Perfect for bedrooms, playrooms, and living rooms, the Coway Airmega AP-1512HH is one of the best-performing, most durable, and most economical purifiers we’ve tested.

Most Popular The Levoit Core 300 air purifier has some strong suits, but in our opinion it falls short of carving out a meaningful niche for itself. Its ideal use would be in a small bedroom occupied by someone who is sensitive to noise.

Also Great With high end air cleaning performance and a whisper quiet fan, the Winix 5500-2 is the perfect combination of power and finesse. It cleared airborne particulates out of our smokey testing room faster than any other model.

Best of the Best If you have a large space you want to remove irritants from, We recommend the Airmega 400S. All of Coway air purifiers do an excellent job of attacking indoor pollutants, and we highly recommend any of them. The 400S is designed to accommodate large room sizes.
