Levoit LV-H135 Air Purifier

The Levoit LV-H135 is finally out there, but at the time of writing you can only find it available on Amazon. Doesn’t matter, this is still the most accomplished air purifier we’ve ever seen from the company, and a bunch of new changes in design to make this one of the best air purifiers you can buy right now. We are happy to be the first honest Levoit LV-H135 Review you can find right now.

Levoit is increasing their popularity more and more in air purifier market, both thanks to their advertisement strategy on Amazon and the actual fame of Levoit LV-H132. In Breathe Quality, we have followed their development day by day, and we are happy to introduce their latest Levoit LV-H135 in our Levoit LV-H135 Review.


For a brand to launch two flagship air purifiers a year is truly rare, and it doesn’t always work, either. There’s often not enough new tech to make for a meaningful upgrade, and bringing a new device to market every six months can cause fatigue for even the keenest air purifier fan.

Levoit has been following the two air purifiers per year schedule since the beginning in 2017, but it seems they are trying to break the regular tradition this year. After the release of Levoit LV-H134, we are welcoming the new introduction of the Levoit Vista 200 and ‘another flagship’ Levoit LV-H135.

Although they have never committed to only make two air purifiers in one year, the release of Levoit LV-H135 is still a surprise to us. Looking closely, I find out that the Levoit LV-H135 is somehow a worthy update to the Levoit LV-H133. Of course, nothing new from the internal, but lots of changes from the outside.

The Levoit LV-H135 price will be $249, at least for now. It is $50 less than the previous LV-H133, and $150 less than this year flagship LV-H134. It’s only have one white version, and it’s worth noting that the Levoit LV-H135 is the only air purifier with built-in casters.

Having said that, the Levoit LV-H135 is competing against a more aggressive segment, a number of high-profile air purifiers have launched before, such as the Honeywell HPA300, AIRMEGA 200M, Coway AP-1512HH and of course, the Medify MA-40, which is supposed to be the inspiration for our today air purifier. I don’t want to mention a list of potential competitors here, but you should know it will be much harder to choose one air purifier within the price range.Top Levoit LV-H135 deals right now

Designed in California. 100% ozone free, does not use ions which produce trace amounts of measurable ozone. For large room up to 463 square feet.


Levoit has embellished the design credentials a good deal in the last couple of iterations of their flagship air purifier, but nothing like the new Levoit LV-H135. It is felt like the culmination of lots of hard work – a great-looking device that didn’t skimp on some of the essentials. I feel the new Levoit LV-H135 like another Winix AM90 or Medify MA-40, or a small version of AIRMEGA 300S and AIRMEGA 400S. It is a compliment, as all these aforementioned air purifiers are high-end machines.

The Levoit LV-H135 uses the 3D rectangular shape, which is different to any cylindrical shape before. In fact, this change is great for setting up the casters at the bottom, and so it is worthwhile, and well implemented.

The body is plastic on both the front and back of the device, and this Levoit LV-H135 is a bit shorter than the LV-H133, with 25 inches in height. It feels comfortable to set up in your house, especially thanks to its rolling base, you can move the air purifier anywhere.

It seems Levoit won’t compromise to change the air flow system concept, and the Levoit LV-H135 still uses the bottom-to-top concept, with the 360° air intake grill and impressive top air outlet.

A brand new display control panel draws attention from users, and I must admit it is really beautiful. The Levoit air purifier will always be the winner of my heart for its pure beauty, and the Levoit LV-H135 could easily be the most beautiful.

Levoit LV-H135 is also lighter than the previous LV-H133, as it is only 18 lbs compared with 21 lbs. With the wheeled design, you won’t find any trouble moving it around your home.


The most important criteria to decide the power of one air purifier is its air filters. Basically we will look at how many filters it has and the air filter types are used. As a flagship of one brand, I had high expectation for the Levoit LV-H135. This air purifier will continue to use the all-in-one air filter from now on, with the 3-stage air cleaning system as below.

  1. Pre-filter – Using the fine preliminary filter, Levoit LV-H135 is able to capture most of the large objects right 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-H135 uses a True HEPA Filter to reduce 99.97% of as small as 0.3 microns allergens, virus particles, pollen, and bacteria particles.
  3. Activated Carbon Filter – This Activated Carbon filter captures and neutralizes smoke and odors from the kitchen, your pets, or even the outdoors.

This is exactly the same air filter being used in the Levoit LV-H133, and if you notice the amazing performance from the previous model, you will likely to love the new Levoit LV-H135. For those who don’t know, this air filter is enough to deal with your common airborne allergies. The certified True HEPA filter is the best method to capture 99.97% of any impurities with size down to 0.3 microns.

Given the internals are much alike to the 2018’s model, I believe the performance rating of this Levoit LV-H135 remains the same. So to say, I used the similar test as the LV-H133, with the room size of 200 square feet and the duration of 1 hour. This time, I chose the Whirlpool WP1000 and Winix U300 as the testers to compare with this Levoit LV-H135. Just like I predicted before, the Levoit LV-H135 scored after both of them, with high efficiency of 99.93% for trapping any particles down to 0.3 microns. For more details, you can look at the chart below.

You need to use the new LV-H135-RF air filter in this Levoit LV-H135. The filter cost is around $84, and you need to replace the filter once in every 6 months.


Levoit; just like a lot of American air purifier brands like Rabbit Air, Alen or Oransi; are more likely to impress their audiences with large room coverage while in fact, their air purifiers don’t have enough fan capability. The Levoit LV-H135, while being as modest as possible, is claimed to clean a large room of 463 square feet.

The ACH of Levoit LV-H135 remains 4X. This Levoit LV-H135 will clean your room every 15 minutes.

The CADR of Levoit LV-H135 is 212 – 235 cfm in general. The CADR rating is not high, but it is not low, either. In real-world use, the Levoit LV-H135 is able to clean your room around 400 square feet really quick, about up to 1 hour.


Levoit is always proud of their quiet operation in every air purifier, and they believe their devices can easily be used in whether the bedroom or the office, where requires silent the most. It is due to the high specialized mechanism of their advanced fan that reduces the noise to a barely audible level.

With 3 fan speeds, you will enjoy the minimum noise level of only 26 decibels, which is virtually silent for any people. Your children won’t be awaken at night, and you still have the clean, fresh air quality.

Even when you run this Levoit LV-H135 at the highest setting, the noise level is just 54 decibels (db). This is the noise level of normal conservation at home or office, and if you are at work, you won’t be interrupted by this air purifier.


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

Levoit LV-H135 advanced brushless motor is able to hold the power consumption as low as possible. I have recorded the power consumption of this air purifier to be only 33 watts, which is nearly half the Blue Pure 121 with 61 watts, or 1/4 the rated power of Whirlpool WP500 with 110 watts.

For this criteria, we can all believe in the Levoit brand. An advanced fan power of Levoit LV-H134 allows this gigantic air purifier to run with a power consumption of only 45 watts. This power consumption is still far behind 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.

If you root for a Levoit LV-H135, you only need to pay for about $12 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.


Just like the Levoit LV-H133 and Levoit LV-H134, the Levoit LV-H135 contains the great Smart Sensor, to help detect any changes in the indoor air quality, and give feedback to you via the LED indicator. Moreover, with the Auto Mode being on, you can clean the room in a smarter way, as the Levoit LV-H135 can automatically adjust the fan speed that match your status the most, and therefore saves the energy.

You still have the sleep mode to keep the air purifier operate at the lowest setting for your night time. The Advanced Timer is also available, so you can schedule your air purifier. These functions are just the most basic ones for any air purifiers in this price range, and I don’t want to dig deep in the detail.

Finally, you will have the LED indicator for filter replacement.

Well, this could be the most anticipated Levoit air purifier last year, as it fills the wide price gap between the Levoit LV-PUR131 and Levoit LV-H133. Levoit LV-H135 has impressive fan power and great air filtration system, as well as a very sleek and convenient appearance to love and use.
