Levoit LV-H134 Air Purifier: Trusted Review & Specs

The Levoit LV-H134 is Levoit’s attempt at making a powerful air purifier that’s capable of rivaling the top of the mid-range, especially the Blue Pure 121 – currently the undisputed king of mid-range tower devices. Thanks to the valuable feedback on the previous Levoit LV-H133, Levoit has made an air purifier that is far outsized by its competitors, both in terms of appearance and room coverage. We’ll find out in our Levoit LV-H134 Review whether this best Levoit is truly a memorable monument that marks another successful year for this brand. 

Update: We highly recommend you read the review of the Levoit Core 600S right after this review, because the new air purifier has a much better value for the price than this Levoit LV-H134. In addition, the new Levoit EverestAir, the most expensive Levoit air purifier to date, is now available.

With flagship air purifiers becoming more expensive thanks to the increasingly high level of air pollution, no one is expecting the upcoming Levoit LV-H134 to come at such a great price as an ideal antidote. After the consecutive success of many air purifiers, it is clear that Levoit is now aiming at a very ambitious goal. In our Levoit LV-H134 Review, we will see what Levoit can achieve if it goes all-out with top-end tech and high-end specs.

Levoit LV-H134 Price

The Levoit LV-H134 is one of the first flagship air purifiers, and it starts the year off with quite a show. A giant size of 32 inches, room coverage of 710 square feet, and a new set of air filters mean this isn’t the kind of air purifier we normally expect from Levoit. Just say bye-bye to the previous low-range army, as since the LV-H133, Levoit has designed the true “flagship.”

The air purifier was announced on January 27, and by that time, it was already listed for sale on Amazon. The Levoit LV-H134’s price is now confirmed to be $399. Typical of Levoit, the price represents good value for money. Each of the bigger versions will have an additional $100 compared with the previous model. With that price, the Levoit brand has approached the level of high-end air purifier brands, which are currently dominated by Rabbit Air and Blueair. We could expect more from this brand soon, as the refresh cycle of the Levoit LV-H134 is much shorter than the LV-H133.

Our review for the LV-H133 indicated directly that the Levoit air purifier can’t hold its own with the Blue Pure 121, so the company finally decided to decrease the initial price, making this LV-H133 a primary opponent of the Blue Pure 211. And then we have the Levoit LV-H134 with 710 square feet of room coverage, which is ready to take on any air purifier in the same price range. The obvious alternatives still include the Blue Pure 121 and GermGuardian AC9600, but we think the Levoit Core 600S is the go-to option.

After the adjustment in the price of the LV-H133, the Levoit LV-H134 can be found for only $299, especially when you get our deal below. Today, it appears that Levoit is taking another step toward high-end entry with the new Levoit EverestAir.

Levoit LV-H134 Design and Size

I would consider 2018 a strong year for air purifier design, and it seems the trend will continue. Most of the popular air purifier brands dare to change the usual design for a better appearance, which we can tell by a few names like Honeywell‘s HPA030B, Guardian Technologies‘ GermGuardian AC9200WCA, or Rabbit Air’s MinusA2. And to be honest, most of the new designs are getting positive feedback.

Levoit previously attempted to steer away from the notch with the LV-H133. As a brand with consecutive improvements in design, clearly the Levoit LV-H134 will replace the predecessor with a new coat. Personally, I believe the result is noticeably better.

Instead of the classic cylinder shape that was once a symbol of Levoit air purifiers, the Levoit LV-H134 features a gigantic size, with a much bigger bottom than anything else on the market. This solid foundation guarantees that the 32-inch air purifier will stand on the ground with no problem. This height makes us feel like the huge Blueair Pro L is still a little smaller than this Levoit LV-H134.

It’s a clever solution, as with such height like this Levoit LV-H134, a same tower design as Honeywell HFD360B will be fallen easily. In my opinion, this design will likely be replicated numerous times in the coming months, by many other Chinese air purifier brands.

From the previous LV-H133, the company brought in an incomplete 360-degree air intake concept, which is now perfect in the Levoit LV-H134. This air purifier still uses the same cylinder filtration layer that maximizes 360-degree air intake efficiency. Though the concept is not new – the Blue Pure 121 and Blue Pure 211 both did it a long time ago—the Levoit LV-H134 does it better than the predecessors with air intake grills in four facets.

The Levoit LV-H134 can now run the bottom-to-top airflow system thanks to the true 360-degree air intake. With its design, a Levoit LV-H134 resembles the $749 Airmega 400S more. Still, it’s an attractive display with bright colors and a neat outlet air grill on top. A brand new LED display with a touch screen is available again in this air purifier.

The Levoit LV-H134 is so bold and eye-catching that it may well be too much for some tastes. It’s not a small air purifier, weighing in at 30 pounds, but which flagships are?

Levoit LV-H134 Filters

The most important criteria for determining the power of an air purifier are its air filters. We will basically look at how many filters it has and what types of air filters are used. As the flagship of one brand, I had high expectations for the Levoit LV-H134, especially when this air purifier still keeps the same 3-stage air cleaning system as its predecessors.

1. Pre-filter – Using the fine preliminary filter, Levoit LV-H134 is able to capture most of the 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-H134 uses a True HEPA Filter to reduce 99.97% allergens, virus particles, pollen, and bacteria particles of as small as 0.3 microns.
3. Activated Carbon Filter – This Activated Carbon filter tackles smoke and odors from the kitchen, your pets, or even the outdoors.

If you’re upgrading from the already great Levoit LV-H133, the main thing you’ll notice about the Levoit LV-H134 is the new air filters. The new LV-H134-RF air filter is an evolution of the previously successful LV-H133-RF air filter, with a sturdy build and real power inside. It’s hard to convey the usefulness of all this power for the average user, one who might not care about the efficiency after all, but it will allow your Levoit LV-H134 to deal with a larger room.

The Levoit LV-H134 is built around a true HEPA filter, which allows the air purifier to perform similarly to the Blue Pure 121. In fact, with a bigger size, this True HEPA filter improves efficiency a lot, thanks to the smart design.

But that is only in theory, and in breath quality, we only believe in the performance test. This time, I can drag the Blue Pure 121 out of our garage, along with the GermGuardian AC9400W, to be the testing samples for my Levoit LV-H134. I run all of them in a room of 300 square feet for 1 hour without interrupting, and the result is, at last, great for Levoit. Blue Pure 121 is still the most powerful, with a high efficiency of 99.95% for any particles that are as small as 0.3 microns, but the Levoit LV-H134 can also deal with 99.92%. For a space of 300 square feet and only 1 hour of running, the result is just incredible.

In terms of out-and-out power, though, this is the most powerful Levoit air purifier I’d ever benchmarked when it launched. But that only relates to the improvement in the air filters, and the Levoit LV-H134’s fan speed won’t help you notice its power in day-to-day use. Levoit has been rapid enough for years, but people are starting to expect even more from its devices. Next time, I wonder what will be inside the Levoit flagship (I didn’t mention the smart Wi-Fi connectivity, but it seems the upcoming Levoit LV-PUR131S will have this feature).

You can estimate the actual air filter replacement cost of this air purifier by comparing the prices of the Levoit LV-H134 and LV-H133. Amazon set the price at $79, and I bet the official price is no less than $90. Comparing the raw cost, the LV-H134-RF air filter is really a staple, as both the Rabbit Air BioGS 2.0 and GermGuardian AC9200WCA are $79. However, this True HEPA filter can only last for 6 months, while the Rabbit Air BioGS 2.0 can last for 2 years, or at least the GermGuardian AC9200WCA can last for up to 8 months. So if you are looking at the annual filter cost, Levoit LV-H134 is actually not so good.

Levoit LV-H134 Room Coverage

The Levoit LV-H133 has done a great job of jumping to the mid-range room coverage level, and the Levoit LV-H134 can push that level a lot farther. That being said, the room coverage of Levoit LV-H134 is 710 square feet, which is even better than the great Blue Pure 121 with 620 square feet or Rabbit Air BioGS 2.0 with 625 square feet. However, due to the tradition of Levoit air purifiers with insufficient fan power for room coverage, I don’t expect much from the Levoit LV-H134.

One thing I’d like to point out is that many air purifier companies advertise using room coverage as a criterion. You need to look at the ACH/CADR rating to decide the fan power of this air purifier (not the air filter’s quality).

The ACH of Levoit LV-H134 is 5X. This Levoit LV-H134 will clean your room every 12 minutes.

The CADR of Levoit LV-H134 is 326 Dust/ 317 Smoke/ 384 Pollen (cfm). With that CADR rating, there is no need for any air purifier knowledge to know that this Levoit LV-H134 air purifier is not the best at dealing with 710 square feet. It is certainly indicated in the manual of the Levoit LV-H134 that you should run this air purifier in a room much smaller than 500 square feet. The CADR rating is used to tell how fast an air purifier can clean a room, and if you want to try your Levoit LV-H134 in a 710-sq-ft room, it will take you longer than normal.

Levoit LV-H134 Sound

Levoit is a cutting-edge brand when it comes to keeping an air purifier’s noise level and power consumption as low as possible. The sacrifice is simply the fan base. Even for a giant air purifier like the Levoit LV-H134, it keeps the same 3 fan speeds to handle a quiet operation.

I recorded the noise level at the lowest setting, which was only 32 decibels, which is lower than the library noise level. Even at its highest setting, the Levoit LV-H134 maintains a noise level of only 54 decibels (dB). Yes, you can notice the sound, but it is just the same as the level of normal conversation at home. Thankfully, the Levoit LV-H134 has a handy Smart Sensor to keep the fan speed mostly at the lowest setting. If you plan to run this air purifier in quiet places, you will be happy.

Levoit LV-H134 Power Consumption

A good air purifier is designed to run for a long time to be more efficient, making the high-priority question in Breathe Quality: “Do air purifiers use a lot of energy?” To know the answer, we will need to check the power consumption of this air purifier.

For this criteria, we can all believe in the Levoit brand. An advanced fan motor in the Levoit LV-H134 allows this gigantic air purifier to run with a power consumption of only 45 watts. This power consumption is still far below the maximum of Blue Pure 121, which is up to 61 watts. That is the exchange we have for this Levoit LV-H134: a little bit weaker fan power for a little bit better power consumption. As a result, the Levoit LV-H134 is certified as an Energy Star air purifier.

45 Watts is an extremely low power consumption for a large room air purifier, and if you buy this Levoit LV-H134, you will only need to pay up to $17 per year, assuming 8 hours of use per day. Yes, I know it is so low that most people will ignore this power consumption easily.

Levoit LV-H134 Additional Features

The Levoit LV-H133 has moved all the smart features from the Levoit LV-PUR131, and again, the Levoit LV-H134 does exactly the same. With a great smart sensor, which is a laser dust sensor, Levoit LV-H134 can detect the real-time air quality and give you feedback that is highly accurate. Moreover, this Smart Sensor allows the Levoit LV-H134 to adjust the fan speed automatically based on current air quality. The original Sleep Mode is widely used because it keeps the air purifier running at its lowest setting during the night.

And don’t worry about the advanced timer or LED indicator for filter replacement. These features are becoming increasingly popular in modern air purifiers, to the point where even air purifiers under $100 can have them.

Levoit still doesn’t add smart connectivity to its air purifiers. The upcoming Levoit LV-PUR131S, which is a smart version of the air purifier with the same name, is predicted to contain these features, and we will review both this device and the function of its app. But for now, you should forget the smart connectivity in this Levoit LV-H134.

Our verdict

The best of the Levoit brand is not just huge outside; its inner ability to cover a large room is impressive. This Levoit LV-H134 is again one of the best power-reserved devices, with good to no sound at all. Personally, I love the Levoit LV-H134, and I believe that the company is doing the right things to improve its products.

But, for the moment, we must accept that the Levoit Core 600S proves to be a much better air purifier.
