Users will have more faith in any air purifiers from the Levoit brand because it is a trusted brand with the excellent Levoit LV-H132. That being said, the Levoit LV-H133 offers fantastic performance, with highlights including large room coverage, more beautiful design than you can shake a stick at, and an excellent CADR rating.

Levoit LV-H133 Price

The Levoit LV-H133 is not only the best thing we’ve seen from Levoit so far, but it’s also one of the best mid-range air purifiers on the market right now, with a great design that beats out the competition.

The Levoit LV-H133’s launch price was $319, which saw it slide below some of its key competitors, but that price has dropped, and the Levoit LV-H133 can now be picked up for only $199. In fact, a bump in price from the $109 LV-H132 is predictable. Levoit needs a mid-range air purifier to close the experience gap with high-end air purifier brands like Rabbit Air, Coway, or Blueair. The tactical Levoit LV-H133 is 2018’s result to enhance this company’s brand awareness.

Since the LV-H132, Levoit has been synonymous with cylinder-shaped air purifiers. Both the price and the design language imply that Levoit LV-H133 is a clear opponent to the Blue Pure 121, though it has a more similar shape to the previous Blue Pure 411. This design is highly inspired by the Levoit Core 400S, which was released long after the LV-H133.

Today, it appears that Levoit is taking another step toward high-end entry with the new Levoit EverestAir.

Levoit LV-H133 Design and Size

Sitting alongside the best-selling LV-H132 as the most wanted air purifier from Levoit, the Levoit LV-H133 retains most of the familiar look, which is hardly something to complain about when you consider that, a year later, the LV-H132 is still one of the best-looking air purifiers around.

You now have the second color option for the Levoit LV-H133, the premium black color. If you loved the previous black version of LV-H132, you’ll surely enjoy the new color.

The Levoit LV-H133 detects the remaining output grill at the top and removes the inconvenient input grill at the bottom. Instead, the Levoit LV-H133 brings in a new cylinder filtration layer to fit the shape of this device and maximize the 360-degree air intake efficiency. However, compared with any 360-degree input air purifiers like the Honeywell HPA300 or the higher-range Airmega 400S, I still notice a slight decrease in air intake in this Levoit LV-H133. It’s not difficult to point the finger at the culprit: the Levoit LV-H133 has only one intake air grill from the front. Therefore, this air purifier is unable to maximize the performance of its 360-degree air filter.

The plastic body is still cylinder-shaped but has also been strengthened and well-built. At the top, you will have a brand new LED display with a modern touch screen. It makes the Levoit LV-H133 feel more modern and deluxe than the old devices.

Having used both the LV-H132 and the Levoit LV-H133, there is a big difference in their sizes. Clearly, the Levoit LV-H133 is bigger at 26 inches in height, but living among a world of huge air purifier machines, the size of this device is still normal and neat. But with a weight of 21 pounds, this air purifier is much heavier than lots of other air purifiers at the moment.

Levoit LV-H133 Filters

The number of filters and air filter types are the most important factors in determining an air purifier’s power. Levoit LV-H133 is a True HEPA air purifier with no change in air filtration process from its predecessors:

1. Pre-filter – Using the fine preliminary filter, the Levoit LV-H133 is able to capture most large objects at the first stage of its air filtration process. In addition, the pre-filter is vacuumable and can be reused for a long time.
2. True HEPA filter – Levoit LV-H133 uses a True HEPA Filter to reduce 99.97% of allergens, virus particles, pollen, and bacteria particles as small as 0.3 microns.
3. Activated Carbon Filter – This activated carbon filter is great at eliminating odors and smoke.

With a very good True HEPA filter inherited from the already excellent previous models and a well-designed air filtration process, it should ensure that no allergens remain in your room. The Levoit LV-H133 separates the 3-stage air cleaning process into 3 separate physical air filters. While it will increase the cost of the air filter, a heavy user of an air purifier may be satisfied with the Levoit LV-H133. The pre-filter functions as a separate HEPA filter that can be vacuumed. It effectively prolongs this filter’s life.

You no longer need to be concerned about the small True HEPA filter because the Levoit LV-H133 comes with an air filter that is three times the size of the LV-H132’s. Moreover, the new filter design increases the efficiency of the Levoit LV-H133’s True HEPA filter and, therefore, the air purification. A good design is really important when Levoit’s air purifiers don’t hold much fan power. However, the performance is still behind the Blue Pure 121, but a performance comparison with this Blueair beast is unfair with any others in the same price range.

To test the actual performance rating of this Levoit LV-H133, I used the Whirlpool WP1000. For the 1-hour efficiency at the highest setting, in a room of 200 square feet, the Levoit LV-H133 had an impressive performance, dealing with 99.93% of any airborne particles down to 0.3 microns.

If you are familiar with the Levoit brand, you will know that the Levoit LV-H133’s air filter cost is triple that of its predecessor, at $84. The filter cost is not a surprise at the mid-range level, though; for example, Winix will charge you $119 for the Winix WAC9500‘s air filter. With triple the size, this air filter cost is acceptable, and I am looking forward to seeing the upgrade in the next LV-H134.

This air filter, named LV-H133-RF, will last for at least 6 months, based on 24/7 use at the highest setting. Also, I suggest that you regularly clean your air filter for better efficiency.

Levoit LV-H133 Room Coverage

The LV-H133, as Levoit’s large room air purifier, clearly covers a much larger area. And with a room coverage of 538 square feet, any household in the US could use this air purifier without any worry. If you still aren’t satisfied with this room coverage, you should check out the Blue Pure 121 (with a better fan and 620 square feet of room coverage).

Also, the ACH of Levoit LV-H133 is improved to 5X. With a much larger room coverage, Levoit LV-H133 needs to exchange the air less frequently.

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 the Blue Pure 121 or Honeywell HPA300.

Levoit LV-H133 Sound

While the Levoit LV-H133 can’t handle more fan power, the bright side of this fan is its extremely quiet operation. Levoit keeps the same 3 fan speeds as used in the previous models and configures the fan to maintain a 25-decibel noise level at the lowest setting. This noise level is actually better than the previous Levoit LV-H132.

The quiet operation continues to be the key advantage of this Levoit LV-H133, even at the highest setting. This air purifier’s noise level doesn’t exceed 54 decibels (dB). This is just the level of normal conversation at home, or many large electrical transformers from at least 100 ft. Well, that’s an impressive noise level, and I’m pretty sure that you can run the Levoit LV-H133 for your whole day without interrupting your silence.

Levoit LV-H133 Power Consumption

A good air purifier must be used for a long time to be efficient, which is why a lot of readers ask us, “Do air purifiers use a lot of energy?” We can all agree that power consumption is one important criterion to use to determine if this air purifier is worth your money or not.

The fan power and power consumption are proportional: the higher the fan power, the higher the power consumption. Levoit exploits this as another key advantage of its air purifiers, and it doesn’t want to miss this strength in the Levoit LV-H133. With a maximum power consumption of 49 watts, this air purifier only consumes half of the maximum energy of the Blue Pure 121 (61 watts). As a result, the Levoit LV-H133 is certified as an Energy Star air purifier.

If you root for a Levoit LV-H133, you only need to pay about $18 annually for this air purifier, with about 8 hours of use per day. I bet that you will turn this air purifier on 24/7 after reading this review, especially when it is one of the few Levoit air purifiers with an Energy Star rating.

Levoit LV-H133 Additional Features

Once the flagship of Levoit, the Levoit LV-H133 shows exactly what the $199 LV-PUR131 could give. This company improves the 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 environment. This high-end feature is a must for any air purifier in this price range to both reserve energy and prolong the air filter’s life. If you want more, I suggest you check out the Levoit Core 400S.

You will also receive an advanced timer for three times the price of the Levoit LV-H132 if you pay three times the price. This Advanced Timer can show you exactly the countdown of this Levoit LV-H133. Personally, I don’t use the timer feature much for testing, but if you’re curious, it works perfectly.

On the other hand, the 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 night time.

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.

Our verdict

Levoit is once again likely to have another popular air purifier for the year. However, with a triple price tag from both the official price and the filter replacement, I don’t think it’s as clear a winner as the LV-H132 was. But with a smart design, better fan power, and lots of handy additional features, the Levoit LV-H133 still holds a certain slot in our ranking of the best air purifiers.

And with the release of the Levoit Core 400S, perhaps we will soon forget about this Levoit LV-H133, which is still a good device to buy but not the best.
