Core 300 is a powerful air purifier with an improved filtration system. It uses a HEPA filter to remove 99.97% of airborne particles as large as 0.3 microns. Pollen, dust, pet hair, pet dander, and bad odors are easily removed with this True HEPA air purifier.
Thanks to the powerful engine that pulls air through filters, Levoit Core 300 can do decent work even in a room as large as 219 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, Core 300 on sleep mode is not detectable. In other words, you can sleep like a baby when turning the sleep mode on.
Levoit Core 300 is light and mobile, which means that you can quickly move it from one room to another and, in such a way, keep the air filtered in a whole house.

Levoit Core 300 Design
Levoit won an iF Design Award with this model. White color with gray details and an amazing touch panel on the top are what fit most rooms. With such a simple yet modern design, Levoit easily took the praise for 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 Levoit Core 300 is small and very easy to use. 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.
Core 300 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 into 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 the dark gray color just makes it visible, but at the same time, it blends perfectly. Air is pulled through the pre-filter, True HEPA filter, and an activated carbon filter, all around the air purifier. This large entry space allows the Levoit Core 300 air purifier to be very efficient.
The power cord cable is large enough, and you won’t need an extension.
The touch panel is well designed. It is sensitive enough and easy to use. 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.
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 Core 300 now has power.
The on/Off button is used to turn the device on or off.
The fan speed button allows you to choose one of three speeds. Cycle through a low, medium, and high speed.
The 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 at 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 the brightness is still too high for you to fall asleep, there is a display off button which will completely turn all lights 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 I 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 air filters.
Size and Dimensions
The Levoit Core 300 is lightweight (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.

Review of Levoit Core 300 Features
The 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, Core 300 air purifier creates strong airflow. AHAM certified CADR (Clean Air Delivery Rate) number is 230+ms/h. All of this allows this air purifier to be extremely useful in a room as large as 219 sq. ft.
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 Levoit Core 300 to stand out in the pack. Thanks to QuietKEAP technology, this air purifier can work while you sleep. Additionally, if needed, the display light can be shut down completely, allowing you to sleep in the complete dark.
Ideal for Large Room
Levoit Core 300 is certified for a room that is no larger than 219 sq. ft. 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.
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.
Levoit is a company with a good reputation, and because of that, the Core 300 has many certificates that prove the quality of work.
The 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 Levoit Core 300 will use as little energy as possible and, in return, help the planet earth as well as your budget in the long run.
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.
The Core 300 is intended for rooms up to 219 sq. ft. It will exchange the air in the room that big for up to 5 times in one hour.
The clean air delivery rate (CADR) for the Levoit Core 300 is 141 for smoke, 140 for dust, and 145 for pollen. CADR is measured in CFM that stands for cubic ft. per minute.
There are many factors that you have to consider when deciding where you should use this device, primarily the room size. It is best to use it in rooms up to 219 sq. ft. You can use it in the slightly bigger rooms, in which case you are going to use the third speed far more than usual.
Levoit Core 300 Filters
Levoit Core 300 uses different types of air filters. However, the original filter is in the initial package. All other filters can be bought separately. You’ll have to replace the filters once the filter indicator turns on. Keep in mind that it’s not wise to wash the HEPA filter because it might create mold. The HEPA filter and carbon filter are replaceable, and you should replace them from 6 to 8 months in this case.
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 a 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.
Levoit Core 300 Replacement Filter
I have personally tested the Original filter, and this type of filter is more than enough to any decent home needs. In my tests, this filter proved extremely beneficial.
Always buy genuine filters for the best performance. As soon as the filter reset indicator is on, you are ready to change filters. Do it as quickly as possible.View Filter Price On Amazon
For a longer lifespan of HEPA and activated carbon filters, clean the pre-filter every 2–4 weeks. I have started to clean the pre-filter more often after I noticed the air purifier works better after the cleaning.
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. The original filter combines a pre-filter, a True HEPA filter, and an activated carbon filter.
Pet Allergy Filter
This advanced filter has all that the 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 litter, cooking smell, or toilet odor.
Toxin Absorber Filter
Just like the Pet Allergy filter, this one also has all the benefits of the 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 the Original filter plus an 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.
The 3-in-1 filter needs replacement every 6 to 8 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 Levoit Core 300 Filter?
If you are not pretty sure how to change your filter please follow the steps I listed above. It will take just 5 mins and your filter will be changed properly.
Total Time: 5 minutes

Levoit Core 300 – Filter Before and After
I have conducted many tests over the Levoit Core 300 and used it for quite some time. Are you intrigued by how does the filter look before and after several-month usage? When I was alarmed by its filter replacement indicator that I should change the filter, I opened its cover and took a picture of the used filter that can be seen in the image below.
Levoit Core 300 made remarkable results on our performance tests, now we confirmed it really does its job, and a filthy filter is an evident indicator.
It absorbed various air pollutants like household dust, pet hair, smoke from the fireplace, and many other.
As always, I have tested noise levels on this model as well. I use a unique noise measurement tool that uses a dBA scale. This means that my 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 fan speed, which is lower than the first fan speed, and because of that, sleep mode on Core 300 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 noise results in the table below.
The maximum noise level is around 64.9 dBA, which is, in my opinion, a bit loud if you plan to use it in the bedroom or any other quiet room.
|Speed 1||46.4 dBA|
|Speed 2||52.9 dBA|
|Speed 3||64.9 dBA|
|Sleep mode||40.7 dBA|
I also performed various performance tests in different room sizes. I used real-life testing, and no laboratory tests were done. In all tests, I used the Levoit Core 300 at its 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 Test
This room is smaller than the recommended room size of 219 sq. ft., and because of that, the air purifier did an amazing job. Since the engine is also powerful in Core 300, the 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|
320 Square Feet Room Test
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, Core 300 did an excellent job.
It improved air quality 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|
As already mentioned under the certificates section, Levoit Core 300 is Energy Star certified, which means it uses very little energy to work. The maximum power that can be used by the Levoit Core 300 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, Core 300 is not using energy. Levoit says it will use less than 0.8W, by my test that is 0.2W.
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.
