Thanks to the powerful engine that pulls air through filters, this air purifier can do decent work even in a room as large as 215 square feet. An interesting fact is that even with a powerful engine that can pull air from the corners of the room, this air purifier is silent at work.

Thanks to QuietKEAP Technology that reduces noise, this air purifier on sleep mode is not detectable. In other words, you can sleep like a baby when turning the sleep mode on.

Design

Levoit won an iF Design Award with this model. White color with gray details and an amazing touch panel on the top is what fits most rooms. With such a simple yet modern design, Levoit easily took the praise on their latest product. But it is not all in looks. High-quality plastic guarantees durability. Everything is sealed correctly, and plastic is BPA Free

The device is small, and you can place it on a table, but at the same time, it is big enough to be placed on the ground or any other place. It is made in a perfect size that fits everywhere. This device can fit any room thanks to a neutral design with neutral colors. Because this is not a large device, it can be completely invisible in the room if you blend it perfectly in the environment.

Levoit logo is not large like we used to see it on other products and is definitely not standing out. It is placed perfectly, and dark gray color just makes it visible, but at the same time, it blends perfectly. Air is pulled through the filters all around the air purifier. This large entry space allows this air purifier to be very efficient. Power cord cable is large enough, and you won’t need an extension.

Touch Buttons

The touch panel is well designed and is sensitive enough. The only problem is that there are no advanced functions that we may find in other models. Also, a bit annoying is that there is no beep or any other sound when you press a button, and you may not be sure if you actually press a button or no. 

Levoit Core 300 - Touch Buttons
Levoit Core 300 – Touch Buttons

Everything can be controlled with a touch panel. As soon as you attach it to electricity, all buttons will light up as a sign that the air purifier now has power. On/Off button is used to turn the device on or off. Fan speed button allows you to choose one of three speeds. Cycle through a low, medium, and high speed. Sleep mode button will turn sleep-mode on, which will allow you to sleep uninterrupted by the air purifier. Not only the air purifier will start running on the lowest speed, but it will also reduce the brightness of touch boutons. In other words, less light will be emitted, and your sleep won’t be interrupted by it. However, if brightness is still too high for you to fall asleep, there is a display off button which will completely turn all light off. 

When using the display lock button, only the power button and display light button will work. Turning off child lock mode is done by holding the child lock button for 3 seconds.

Timer button we have seen in many other air purifiers. It is, without a doubt, one of the most essential features. A display lock is also a useful feature that will allow you to lock the touch panel. The only button that can be used is the power button when the display lock is on. If you want to unlock buttons, you need to hold the display lock button for 3 seconds. The filter indicator will let you know when is the time to change filters.

Size and Dimensions

Core 300 is light (7,5 lb), as already mentioned, and that allows this air purifier to be mobile. The plastic used in production is not slippery, and you will have a good grip when moving it. Thanks to the small size (8.7 x 8.7 x 14.2 inches), it can easily be placed on a table, nightstand, working table, desktop, or anywhere else in the house.

Accessories and Parts

When you buy Levoit Core 300, you should get one air purifier with one True HEPA three-stage original filter, which will be pre-installed. User manual to read all you should do to start successfully as well as a quick start guide if the user manual is too long to read.

Features

Engine

Already mentioned engine that pulls air is much better in Core 300 than in the LV-H132 model, which makes Core 300 a worthy successor. Together with VortexAir Technology, this air purifier creates strong airflow. AHAM certified CADR number is 230+ms/h. All of this allows this air purifier to be extremely useful in the room as large as 215 square feet

Levoit Core 300 Air Purifier Features
Levoit Core 300 – Air Purifier

The engine is durable and will work for ages thanks to the AC capacitor motor, which uses durable high precision bearing, which with excellent internal structure, increases abrasion resistance. In return, you get an engine with extended life.

Silent And Ideal For Sleep

Silent work is what makes this air purifier to stand out in the pack. Thanks to QuietKEAP technology, this air purifier can work while you sleep. Additionally, if needed, display light can be shut down completely, allowing you to sleep in the complete dark. 

Ideal for Large Room

This air purifier is certified for a room that is no larger than 215 square feet. In such a room air purifier can filter all air five times in one hour. Thanks to the three-stage filtration system and three fan speeds, this air purifier can remove 99,97% of airborne particles. 

Levoit Core 300 has memory and will remember last used settings before shutting down. This memory allows it to use the same settings on the next run.

Smart Change Filter Indicator

The indicator will let you know when filters need to be replaced. No need to mess with a filter before the light goes on. This indicator will help you get the maximum from the filter.

Certificates

Levoit is a company with a good reputation, and because of that, the Core 300 has many certificates that prove the quality of work. A most important certificate without a doubt is CARB, which means that this model is allowed to be used in California. We know that California has strict laws, and Levoit Core 300 has passed all of them. Other than CARB, I need to mention the Energy Star certificate, which guarantees that this device will use as little energy as possible and, in return, help the planet earth as well as your budget in the long run.

Warranty

Levoit generously gives a one year warranty on this product. However, if you wish to get an additional one year warranty, you can do that by registering on http://levoit.com/bonus. Make sure you register in 14 days since buying the product. If you do that you will have a full two-year warranty.

Filters

You can use four different types of filters with Core 300. However, the original filter is in the initial package. All other filters can be bought separately. All filters need to be replaced once the filter indicator turns on. You should not try to wipe the filter, vacuum it, or use water on it. These are replaceable filters, and they need to be replaced.

You should never experiment with filters and use essential oils. This kind of experiment may be dangerous to your health as well as your property. All filter packages have nylon mesh pre-filter that does a great job at catching large particles and, in such a way, prolonging the life of the primary HEPA filter. Let’s see which filter is good for what.

Original Filter

Just like the name says, this original filter will come with the air purifier. This filter is good at removing airborne particles as well as removing bad odor. It is very useful against allergens, dust, and not heavy odors.

Levoit Core 300 Original Filter

We have personally tested the Original filter, and this type of filter is more than enough any decent home needs. In our tests, this filter proved extremely beneficial.

View On Amazon

Pet Allergy Filter 

This advanced filter has all that Original filter has plus an additional high efficiency activated carbon filter, which helps at removing strong odors. It is very effective against pet allergies, strong odors like pet liter, cooking smell, or toilet odor.

Toxin Absorber Filter

Just like the Pet Allergy filter, this one also has all the benefits of Original filter, but it also has an even stronger high efficiency activated carbon filter. The powerful carbon filter is beneficial against strong odors, smoke, cigarette smoke, toxic fumes, VOCs, vehicle exhaust, and other toxic air pollution. 

Mold Bacteria Filter

Mold Bacteria filter is focused more on organic pollution. It has all benefits of Original filter plus additional antibacterial filter that eliminates germs, as well as prevents the growth of bacteria and mold inside air purifiers.

If the Original filter is not good enough because you have a person that continuously smokes in a room, or maybe you have pets, then I suggest checking and get an additional filter dedicated to your needs.

Filter Replacement

The filter needs replacement every six to eight months. However, if you notice a weird noise coming from an air purifier, low airflow, clogging, or if the air purifier is not purifying air as before, then you should also look for a new filter.

Every two to four weeks, you need to clean the pre-filter to prolong the life of the primary filter.

How to Replace Filter

  1. Unplug Air Purifier.
  2. Remove Filter Cover.
  3. Take out the old filter and wipe the inside of the air purifier of all dirt and dust. You can use a dry cloth or even vacuum cleaner to do that.
  4. Unpack a new filter and place it inside the air purifier.
  5. Put the cover back and close the filter door.
  6. Turn the air purifier on, press and hold Check Filter Indicator for 3 seconds.

Noise

As always, we have tested noise levels on this model as well. We use a unique noise measurement tool that uses a dBa scale. Which means that our results may be different than the original ones done by the manufacturer. This air purifier has three speeds, actually four if we count sleep mode as well.

Sleep mode runs on the lowest speed, which is lower than the first speed, and because of that, sleep mode on this device is very useful and extremely quiet at work. Even if you can’t sleep with noise by placing this air purifier on sleep mode, you will sleep with no trouble. All thanks go to QuietKEAP Technology, which drastically reduces noise. Check our noise results in the table below.

Speed Value (dBA)
Speed 1 46.4 dBA
Speed 2 52.9 dBA
Speed 3 64.9 dBA
Sleep mode 40.7 dBA

Performance

We also performed various performance tests in different room sizes. We used real-life testing, and no laboratory tests were done. In all our tests, we used the highest third speed. This small air purifier has excellent performance, and on the third speed, airflow is impressive, which personally surprised me.

194 Square Feet Room

This room is smaller than the recommended room of 215 square feet, and because of that, the air purifier did an amazing job. Since the engine is also powerful in Core 300, results did not surprise me at all. In only one hour, AQI was reduced from 111 to 8. Air quality improved by 93%. In an additional 30 minutes, AQI was additionally reduced to 6.

# Starting Baseline After 60min
PM 2.5 83.8 5.8
PM 10 117.4 8.1
Particles 121651 8419
AQI 111 8

320 Square Feet Room

This room is a bit larger than the recommended size. However, even in such a large room as well as much larger than the recommended one, this air purifier did an excellent job. It improved air by 92% in only one hour. It reduced AQI from 145 to 12.

With Core 300, you will be extremely satisfied when you find out that it is efficiently purifying the air in a room larger than recommended.

With such great results, even in a bit larger room than recommended, it makes me say that this is definitely one of the best buy air purifiers on the market.

# Starting Baseline After 60min
PM 2.5 111.1 8.8
PM 10 155.5 12.3
Particles 161125 12813
AQI 145 12

Operating Cost

As already mentioned under the certificates section, this air purifier is Energy Star certified, which means it uses very little energy to work. The maximum power that can be used by this device is 45W. If you use it at maximum speed for 24h every day for a whole month, you will only spend 3.8$ if the energy price is 0.12$/kWh. While on standby, this device is not using energy. Levoit says it will use less than 0.8W, by my test that is 0.2W.

Levoit Core 300 - Power Engine

However, operating costs will be high in a month when you will need to replace the filter. Also, buying additional filters to filter specific pollution will be an additional cost.

Speed Power Usage (W)
Speed 1 29.4W
Speed 2 31.4W
Speed 3 43.5W
Stand-by 0.8W
