The Levoit LV-H134 and Levoit LV-H135 are large-room air purifiers with high CADR ratings, but the LV-H134 cleans larger areas. Even though they have similar dimensions, the pricier, cuter LV-H134 is taller. Both offer an auto mode and air quality sensor, but the LV-H134 also monitors PM2.5 pollution levels.

Design-wise, these large room air cleaners from Levoit, a leading air filtration technology company are a little different. While the LV-H135 features a rectangular shape and looks pretty much like a Medify air purifier, the nicer-looking LV-H134 has the more common cylindrical design for Levoit air purifiers.
However, polluted, germ-laden air gains entry into both devices via the bottom portion of the white plastic body. After air has been completely treated and sanitized, it pours out via the top. You can plant either device against a wall without sacrificing air circulation significantly.
The control panel in both air cleaners is at the top of the machine, just like it is in most air purifying products from Levoit. And because these two allergen eaters are a little heavy, each comes with a set of 4 casters so you can roll the unit to wherever you will whenever you wish.
Levoit LV-H135 vs LV-H134 Dimensions and Weight
The Levoit LV-H135 happens to be a little lighter and less bulky than the LV-H134. Here are the specifics in terms of product dimensions and weight: LV-H135: 13.50″ x 13.50″ x 25.0″ and 17.81 lbs vs 13.70″ x 13.70″ x 30.90″ and 28.50 lbs for the LV-H134.
As you can see, both contenders are somewhat heavy and tall, but the LV-H134 is heavier and bulkier than the LV-H135. Small wonder Levoit decided to construct the air cleaners as a wheeled design.
So, consider whether you have enough room for either unit, especially if you choose to buy the LV-H134. But neither is extremely bulky and you won’t get a headache wondering where to place them.
3-Stage Filtration Technology Leveraged
Both air purifiers arrive with a complete set of pre-installed True HEPA along with a fine preliminary filter and an activated carbon filter. The prefilter captures particulate matter that’s a little larger in diameter, contaminants like pet hair, pet dander, lint and more. The Main filter, a H13 True HEPA filter (a medical-grade allergen eliminator) takes out at least 99.97% of 0.3 micron airborne particles and everything else larger than that.
What about sub-PM2.5 airborne particles, the ones that potentially cause the most threat to your smaller than 0.3 microns.
The last part of the 3-stage filtration offered by these devices is the pet odor eliminating filter, or the activated carbon filter. When it comes to freshening rooms after people have been enjoying their smoke or after someone has been farting around the house (seriously!), it’s hard to find competitors that do a better job.
These two picks come loaded with enough activated carbon so pet odors, cooking smells, VOCs, exhaust fumes, and other such contaminates can be sufficiently addressed. Levoit claims that the LV-H135 uses a High-efficiency activated carbon filter, but I tell you it’s not an ounce different than the activated carbon filter the LV-H134 uses. That sounds like everyday dollar-focused marketing language to me.
Any Unique Air Filtration Technology?
According to Levoit, the LV-H135 levers its unique Spiral Air Out design that supposedly enables the unit to operate at 40% more efficiency than other air purifiers. But is it like Levoit tested every air purifier ever manufactured? Your guess is as good as mine here, friend.
The LV-H134, on the other hand, relies on its much-touted Cyclone Technology that boosts its air filtration efficiency by as much as 50%. Again, the manufacturer claims that this air cleaner takes out air pollutants 50% faster than similar devices from other brands. But how accurate is that assertion? I have not seen any numbers backing up that claim, and I’d take it with a pinch of salt.
Maximum Area Cleaned
To understand how much space each of the two air purifiers would cover, we must turn to each product’s Clean Air Delivery Rate. With a CADR of 312, the LV-H134 purifies confined spaces as large as 710 square feet. In a room that spacious, this air purifier replaces all the air in the room with fresh air 3 times every 60 minutes. That’s an ACH of 3, and you need a better number if you’re allergic to dust and a host of other nasty allergy triggers.
By comparison, the LV-H135 brings to your interiors a CADR of 212, which is phenomenally less than what its larger sibling offers. With this air cleaning product, you’d get an ACH of 3 in a large room with an area of 463 square feet.
Ideal Purification Coverage
I applied AHAM’s 2/3 rule (in reverse), and I calculated the ideal square footage each of these contenders is best suited for. The LV-H134 would work most efficiently in rooms with an area not bigger than 468 square feet. Comparatively, the LV-H135 would work most satisfactorily in 318 square rooms.
If deployed to rooms that large, the user would enjoy at least 5 air changes or an ACH of 5 in the recommended purification coverage. If you have been waking up with a stuffy nose or really sinuses, consider using a unit where it’d deliver not less than 5 air circulations.
Filters serve the homeowner for as long as 8 months depending on the amount of dirt in the room being cleaned. If the air quality in your location can be described as terrible, you may need to buy filters every 4 – 6 months or much sooner than that. Thankfully, the LV-H134 replacement filter (LV-H135-RF) as well as the replacement filter for the LV-H135 are pretty affordable. And you can find them on Amazon most of the time.
Filter replacement for both options is as hassle-free as it gets. No one would ever need help swapping out their soiled filters and inserting fresh filters in their place. With either purifier, just detach the cover from the unit’s side, take out the old air filter, and put in a brand new 3-in-1 HEPA filter. And oh, both choices have a magnetic safety trigger that ensures you plug in the filters right. If you ever insert the filters incorrectly, neither device would turn on.
I just checked the filter price on Amazon, and I noticed that the LV-H135 filter costs a little less than the LV-H134-RF 3-in-1 pack. But the price difference wasn’t significant — about $5 as of this writing and likely wouldn’t deter or encourage anyone from going with either choice.
Remember to remove the plastic covering from the pre-installed filters before use.
Features and Specifications
While the features are pretty similar and do the same job, I have highlighted a difference or two between the two deals. More on that in a bit.
Both air cleaners offer a programmable timer so you can control your purifier more intelligently and conveniently. But there’s a small difference between the timer in the LV-H135 and LV-H134. In the LV-H135, the timer gives you an 8 hour timer offering 3 timer options, 2, 4, and 8.
But with the LV-H134, the timer is a 12 hour timer allowing you to choose one of 12 timer options. Well, I have seen 24-hour timers with comparable allergen removers, but I don’t see this as a bummer at all.
The other feature these two options have in common is a mechanical filter-change reminder. The indicator comes on every 6 months whether the filters need to be replaced or not. Meaning you don’t always need to put in fresh air filters every time the filter replacement indicator lights up.
Auto Mode and Air Quality Indicator and PM2.5 Detector
One more common feature between the LV-H134 and LV-H135 is the auto mode and air quality monitor that communicates pollution information using a coded color system. But the LV-H134 offers a little more than this; its indoor air quality management arsenal also includes a PM2.5 particle counter or monitor.
3 Fan Speeds
Every time the air in the room needs improvement, the auto mode handles the job. This feature instantly relays information to the air purifier, commanding it to put a higher/more powerful fan speed to work to address the adverse air quality situation. Each purifier offers 3 fan speeds namely Low, Medium, and High.
You also get a night mode or sleep mode with either choice. In addition, each purifier has the ability to remember the setting it had before it got turned off. That’s a nice little addition that should theoretically save you a bit of time over the machine’s lifespan.
Adjusting the LED Display’s Brightness
Other features include a fan speed indicator and a display off button to dim the LED light from the control panel. There’s also a night mode that automatically sends the air purifier working a little faster to restore the room’s air quality back to healthy levels.
Lest I forget, you can actually adjust the brightness of the LED display for the LV-H135. To change how bright or less so the display is, simply place your palm over the air quality indicator. Note that using your finger to do this may not work as well as you’d like.
The LV-H134 doesn’t offer this feature, and that’s a bit of a bummer, but the disadvantage fades when viewed alongside this device’s many other great features, particularly the PM2.5 detector.
As far as energy consumption, both units require about the same amount of power to do the job properly. The LV-H134 comes Energy Star rated 45W while the LV-H135 has a power usage rating of 40W. Not an appreciable difference you’d say.
But the overall energy consumption for the two air purifiers isn’t anything anyone would worry about. It’s similar to what your freezer, laptop, or fluorescent lamp consumes. While the more powerful LV-H134 only needs 5W more than its significantly less virile LV-H135, it cleans a much larger area. That’s why I consider it the better option in terms of overall efficiency. I mean, the LV-H134 does a lot more with less.
The two Levoit pet dander, pet odor, and VOCs removers are fully certified, that is, they have all the vital certifications for a decent air purifier. They’re CARB and FCC certified as well as ETL listed. You shouldn’t have any worries as you put either device to work anywhere in your home. With either pick, your worries concerning some bacteria, viruses, dust mites, pollen, mold spores, dust and other allergens should lessen significantly.
Anywhere in the room? Yea, pretty much anywhere, just ensure the operating conditions aren’t out of +degree Celsius range. Relative humidity-wise, be sure not to use either unit where the RH soars past the 85% mark.
Is either allergen eliminator too loud? Thankfully not. The LV-H134 does the air purifying job at 25 dB on low while cranking out not more than 54 dB at maximum air filtration efficiency. In comparison, the Lv-H135 purifies air at 26 dB on low. But I no ears wouldn’t easily detect a difference in the noise levels between 25 dB and 26 dB.
But how loud does the LV-H135 get? Not more than 54 dB; it’s pretty much the sleep-inducing white noise its sibling produces at fan speed 3 (High). Both air purifiers have 3 fan speeds to turn to whenever the need to get rid of pet dander, dust mites, mold spores, pollen, and household odors arises. Neither choice wins in the quietness department.
The Levoit LV-H135 and its sibling the LV-134 are decidedly pricey, costing well past $240. In fact, the LV-H134 sells at significantly more than that. You’ll have to shell out as much as $150 more if you opt to buy the LV-H134.
Should any reasonable allergy and asthma pay the much for the costlier model? Are the extras with the LV-H134 compelling enough to justify the price difference? I believe the addition of the PM2.5 particle counter and the increased air purification power majorly account for the price difference. And did I tell you that the PM2.5 particle sensor for the LV-H134 gets powered by advanced, accurate laser technology?
The LV-H134 thrashes allergens and allergy triggers in relatively larger rooms than does the LV-H135. It’s a CADR of 312 for the former compared with a CADR of 212 for the LV-H135. One typically pays more to get more value, and I’d happily pay the extra $150 to access the increased filtration might of the LV-H134.
Each option boasts a 1-year warranty coupled with a 30-day product testing period so you can return the air purifier in case it doesn’t impress you.
Levoit LV-H134 Vs Levoit LV-H135: Final Word
What’s the best large room air cleaner from Levoit? Is it the cute workhorse, the Levoit LV-H134 or the comparably powerful LV-H135? I’m torn between these two allergen, smoke, dust mite, and pet dander removers, but I must now decide which device I like better.
Both of them look nice, have the exact same clean large areas, and provide a near real-time (lags by not more than 30 seconds) air quality reading. But the Levoit LV-H134 goes a mile further and calculates real-time PM2.5 numbers, and that’s a really nice capability. However, the LV-H134 dents your air quality improvement budget more significantly than the LV-H135 does. But there nothing like more benefit for less, at least, that not the case for the most part.
I have no doubt at this point that the LV-H134 ix the better offer here. I’d go for it any day if money wants a hindrance for me. What do you think?
