Blueair 211+ Vs Levoit Core 600S – Trusted Comparison!

oday’s article is about two large air purifiers: the Levoit Core 600S and the Blueair 211+. These two devices are entirely different.

They look different, their design philosophies differ, and so does their filtration technology and controls. All of this makes the comparison challenging and exciting, and I’m sure you will enjoy it.

The Levoit Core 600S is suitable for rooms of up to 635 sq. ft. (59 m²), while the Blueair 211+ covers slightly smaller rooms of up to 540 sq. ft. (50 m²). Both units will clean the air 4.8 times per hour in their recommended room sizes.

Regarding filtration technology, the Levoit uses a three-stage system consisting of a pre-filter, a main filter, and an activated carbon filter. The Blueair, on the other hand, uses a four-stage system consisting of a pre-filter, a particle filter, a charcoal filter, and HEPASilent technology.

Specs: Blueair 211+ Vs Levoit Core 600S

Performance Test – Comparison

It’s interesting to mention how Blueair 211+ has a CADR of 350 CFM (595 m³/h) while having a 61W powerful motor, whereas Levoit Core 600S has a CADR of 410 CFM (697 m³/h) but uses less power to operate, only 40W.

Starting from this point of view, I have decided to run three separate tests to have a real insight into each air purifier’s performance.

Each test lasted 60 minutes, leaving the air purifiers constantly operating at maximum speed level.

The most important test for this comparison is one in a room of 560 sq. ft. (52 m²), in which the Levoit Core 600S improved air quality by 96%, while the Blueair 211+ improved it by 92%.

It’s clear that the Levoit performed much better in these tests.

However, it’s also worth mentioning that the Levoit Core 600S improved air quality by 93% in a 730 sq. ft. (68 m²) room, while the Blueair 211+ improved air quality by 96% in a 320 sq. ft. (30 m²) room.

Smoke Box Test – Comparison

Besides the airborne particle removal tests, we also tested these two air purifiers’ smoke removal performance.

We placed each air purifier in our smoke box, which we filled with the smoke, and measured how much time was needed for each to remove all the smoke from the glass box.

The Levoit Core 600S needed just 9 seconds, while the Blueair 211+ needed 11 seconds.

Although both devices have high CADRs, the Levoit comes with a much better carbon filter, which is the reason why it performed better in this test.

Noise Level Test – Comparison

Unlike the three basic low, medium, and high speed levels that Blueair offers, Levoit comes with two additional ones: sleep and turbo mode.

With 43.9 dBA produced, Blueair’s lowest fan speed equals the amount of noise Levoit produces while in sleep mode.

As it turned out, having an advanced feature didn’t work out in favor of Levoit, right? The highest Blueair fan speed produces about 59.7 dBA, which is significantly lower than Levoit’s turbo mode with 68.5 dBA.

With a powerful motor and its large size, Blueair seems to be doing an excellent job with a decent amount of noise produced.

If sleep mode could be added, the value of this product would significantly increase.

On the other hand, Levoit proclaims the nighttime usage of its air purifier, but it doesn’t seem to deliver. Personally, I would never use it during the night, because it makes way too much noise for a decent sleep.

Even at its maximum setting, the noise exceeds the limit of my tolerance. To sum it up, I think that Blueair 211+ is far more tolerable than Levoit, and therefore has my verdict in favor.

Operating Costs – Comparison

As easy as it may seem, I had a lot of thinking before deciding which air purifier deserves to be called a cheaper option, and here is why.

Both Blueair and Levoit have approximately the same market price, with new filter prices just a few dollars apart.

At the same time, if you put each air purifier into 24/7 operating mode throughout the whole month, the electricity bill will come to $4.29 for the Blueair as opposed to $4.22 for the Levoit.

Where is the catch, you may wonder? Well, it all comes to one important matter. The filter replacement rate. With the Blueair 211+, you would have to change filters at least twice a year, while with the Levoit Core 600S the replacement will occur once every 12 months.

Now you see why I never take things for granted and always search for a different perspective. And this is exactly the reason why I think Levoit would cost you less if paying the bill is the most important decision-making factor to you.

Features Overview

Regarding features that each air purifier owns, the scale weighs in favor of the Levoit air purifier since Blueair doesn’t have as many advanced options as Levoit.

However, the available Blueair functions are good enough to keep this air purifier a justifiable opponent in this comparison.

Control Panel

As you can see, the Blueair 211+ enjoys a reputation as a pure minimalistic air purifier. You get an all-in-one button placed on the front side. With each button press the fan speed changes, and that is how you control the device. In addition, this button can also be used when you need to reset the filter indicator upon filter replacement.

Contrary to the Blueair air purifier, the Levoit Core 600S air purifier has a control panel on top with plenty of indicators and buttons as an indicator itself. Along, there is also a PM2.5/Timer display. However, this device is fully controllable through the Smart app, which means all these buttons have a correlating Smart app function.

Air Quality Sensor and Air Quality Indicator

One of the first important features that Levoit has as opposed to Blueair is the air quality sensor and an air quality indicator. Coming in the form of an AirSight Plus laser particle sensor, located at the rear side of the unit, this sensor has the task of detecting real-time PM2.5 particles.

Once the real-time data is collected, it gets displayed on top of the device whereas the air quality indicator reacts by emitting a colored light depending on the collected data.

The colors of the indicator may vary from blue to green to orange to red, all based on the level of air pollution in the room.

This is the simplest way of receiving information on how polluted the air is in the room you are currently residing. Though it seems needless to say I must remind you that all of this you can find in a smart app, too.

Auto Mode 

Being available only within the Levoit air purifier, the Auto mode works correlating with the air quality sensor and indicator. If you turn it ON the air purifier will immediately adjust the fan speed according to the data given by the AirSight Plus sensor and keep it operating as long as it takes for the air to be safe again. Never expect the Auto mode to run at turbo speed. 

You can use this option through a Smart app, in the form of 3 extra modes: the Quiet, the Efficient, and the ECO Auto mode. I will not be explaining it thoroughly now, but if you wish to find out more, check the Levoit review on this link.

Filter Reset Indicator

With this feature installed, you will never have to worry if you would forget to replace the filter. This indicator will light up and notify you of soon filter replacement. The good thing is that both Blueair and Levoit air purifiers have this feature.

Sleep Mode

A sleep mode is another feature only available within the Levoit Core 600S. It is the kind of feature that makes the air purifier your true ally during the night.

By lowering the fan speed to a minimum and turning off all of the indicators within six seconds, you will hardly notice it is running in the background out there in your bedroom. 

Smart App

The Levoit Core 600S can be treated as an advanced air purifier in this comparison, thanks to the VeSync Smart app. VeSync is not just a remote control app; you can find many different information, notifications, and access to some options that are not available directly on the device.

The best thing is, it is available for iOS and Android users. 

Smart Plug Compatibility

I have mentioned priorly that the Blueair 211+ is smart plug compatible. Let us be clear, this air purifier doesn’t have some fancy and distinguishing advanced features, and being smart plug compatible cannot compensate for that.

However, this option enables the connection between the air purifier and the user through his cell phone. All that needs to be done is to connect the air purifier to a smart plug, and you will be able to use some basic controlling options. The interesting part is that thanks to this feature the air purifier remembers the last setting before it shut down, and it will continue operating at the same level once you turn it back on.

Screen Off and Lock Screen 

These are two very useful features installed only within Levoit Core 600S. You will find these features precious if you have pets or kids, or even both. The reason is simple: you want to prevent your child or restless pet from interfering with the purifying process of your new favorite home appliance. One simple button hold will keep the unit safe. 

Switching the screen off will dim all the indicators on the air purifier and adjust it to, for instance, bedtime. It is pretty much like setting the Sleep mode ON.

Personalized pre-filters

One of the appealing differences that set the Blueair 211+ apart from the Levoit Core 600S is an adjustable design. This is present only within the Blue Pure series of air purifiers, and it seems as if the producer wanted to give its product some extra value or appearance that will make it distinguished among so many air purifiers on the market.

I am talking about the replaceable pre-filter that comes in the form of fabric available in five different colors: Lunar Rock, Crystal Pink, Dark Shadow, Buff Yellow, and Diva Blue.

So, if you are bored or simply want to play with colors and your interior design, you can order different colored pre-filter and replace them very easily.

Light Sensor

Not many air purifiers I tested so far have a light sensor as a feature, but Levoit has it in a bit of an advanced version. If you want to use this sensor, you can do it only through the Smart app. Once you turn it ON, the sensor reacts to the amount of light in the room and, at the same time, adjusts various operating settings.

The light sensor will not interfere with the air purifier operating process when there is light in the room. The minute the light sensor stops detecting any light source in the room, categorizing it as dark, all of the indicators will be dimmed, and the unit will be adjusted to the nighttime conditions and operating mode.

Timer

Available only within Levoit Core 600S, you can set the operating time between 1 and 12 hours. However, there is also a solution for those of you who like to keep long-distance control. Using the timer option through the VeSync app you can set the time between 1 and 24 hours. 

Airflow

Although these comparing devices are different in size, they come in rectangular shapes with rounded edges.

Both Blueair and Levoit have air inlets positioned all over the bottom part, allowing full air intake to go through the filtration system, eventually being released through the grills on top of each device. 

Warranty

Blueair 211+ air purifier comes with an initial 1-year warranty which I find extremely low for any kind of device. However, the producer will provide an additional year of warranty if you register the purchased product on their website. Though I dislike being conditioned, in any kind of way, I find this an easy task to do with a lot to gain in return.

Contrary, the Levoit company provides a 2-year warranty which is okay at first since we are talking about a brand followed by a good reputation with reliable and durable products.

Filtration Technology 

Essentially, each air purifier has a 3-stage filtration process. As different as they are, both Blueair and Levoit are highly efficient.

A pre-filter is there to collect all the large particles that can be trapped easily, like dust, hair, pet hair, like, etc. The main difference between the two comparing products is that the Blueair has a washable pre-filter, whereas Levoit Core 600S doesn’t. Nevertheless, you can keep Levoit’s pre-filter clean by doing a simple vacuum once a month, depending on how much dust it collects. 

As much as I prefer when an air purifier has a True HEPA filter like the Core 600S does, I can’t deny that a particle filter within the Blueair 211+ does a great job. By removing airborne particles such as pollen, dust, pet dander, and so on, it manages to deliver outstanding results. 

A third filtration stage belongs to a carbon filter, whereas Levoit has an activated carbon filter made of carbon pellets, and Blueair has a carbon-coated fiber filter. Blueair’s carbon filter does a pretty good job of neutralizing all the unpleasant odors that come from cooking, smoking, or pets. However, it simply can’t stand too much exposure to these odors. 

Contrary, Levoit uses an exclusive ARC formula, which has provenly shown effectiveness in neutralizing not only the odor that comes from cooking or smoking, but also the invisible ones such as formaldehyde, benzene, ammonia, hydrogen sulfide, and volatile organic compounds (VOCs).

In addition, the Blueair 211+ is equipped with HEPASilent technology, practically an ionizer that is integrated and cannot be switched off. But don’t worry. The air purifier owns a CARB certificate meaning that the Blueair 211+ is safe to use and does not produce illegal amounts of ozone.

How to replace filters on both of these devices?

Replacing filters on any of the two comparing air purifiers is not a difficult task to do. Actually, it is quite simple, but the main difference reflects in how to maintain the filters within each air purifier.

For example, Blueair has a washable pre-filter, meaning, there is no need to buy a new one once it gets dirty. All you need to do is wash the fabric.

On the other hand, the Levoit does not have a washable pre-filter, which means you’ll have to vacuum or clean it with a damp cloth every once in a while. All of the other filters are also not washable and will need a replacement in due time.

On average, filters within the Blueair 211+ air purifier last around six months, while Levoit filters can last up to 12 months before the replacement.

Anyway, since both devices come with a filter reset indicator, you will be notified at the proper time to do the replacement.
