The Levoit Core 300 Air Purifier

Levoit core 300

For many years I have suffered terribly from pollen allergies. However, the thought of investing in an air purifier hadn’t occurred to me until I recently also started suffering from allergies caused by simple household dust. A close friend recommended their use, saying they too have dust allergies, and that an air purifier has significantly reduced their symptoms.  The Levoit air purifier offers a personalized filtration system. So, that means that I could choose a filter which best met my needs.

If energy prices are always a concern but the Levoit air purifier is energy star rated. So that means that it’s met strict energy efficiency guidelines set by the US EPA. The last thing you want is to buy an air purifier but then be too worried to use it effectively because of the running costs.

  • Customizable Filters
  • Ultra-fine pre-filter for removing particles as small as 0.3 microns
  • Silent Mode
  • Timer and filter life display helps you control when filters need to be replaced.
  • Larger than some similar models
  • It can cover up to 20 sq./m. This means open plan living areas may be too large for the purifier to be effective.
  • Remote control would be welcome.

Key Features of the Levoit Core 300 Air Purifier

1.  Excellent Clean Air Delivery Rate.

The device has a CADR (Clean Air Delivery Rate of over 135 cubic feet per minute. Assisted by the purifiers Vortexair system, you really can feel the air get cleaner – fast. I have actually found this to be of particular benefit in the kitchen. When cooking, sometimes the smell of food can be overpowering, and it quickly spreads throughout the home. However, the Core 300 has excelled itself in keeping the air clean and odor-free and doing so in a matter of minutes.

2.  Personalized Filtration System

The ability to not only quickly and easily replace filters, but to tailor the filtration system to your needs is fantastic! Two of the three filters housed within the Levoit Core 300 should be replaced every 6 to 8 months. The third filter can be cleaned regularly to ensure it stays fresh.

For my dust and pollen allergies, the cleanable filter that is supplied with the unit is perfect. However, as mentioned earlier, a range of replacement filters are available to combat more specific problems. These include pet allergens and odors, higher levels of pollution (useful if you live near a busy road), and mold bacteria, which I can imagine would be particularly helpful to those living in older houses

3.  Compact Design

This air purifier is also compact. There are, of course, smaller units available not only from Levoit but also other big names in air purification. However, none have this level of performance or features. Measuring 8.7 inches x 14.2 inches (that’s approximately 22 cm x 30 cm), the device can be used almost anywhere. It can be placed on your desk, on a shelf, or even the bedside table. Its size is perfect for what it can deliver!

4.  Low Noise

Having such a fast delivery rate of air would lead some people to believe that the unit would be noisy, at least to a point where it may be annoying. However, I haven’t found this to be the case. The manufactures claim of low noise output is completely valid; you can hardly hear the purifier when it is in operation. Then, the silent mode, which is claimed to be as quiet as 24db, really is silent. I imagined when using the purifier at night next to my bed that it would keep me awake – but that hasn’t happened. I honestly can’t hear it running and have even checked once or twice to make sure the device was still switched on.

5.  No Ultraviolet or Ion Light Used

Another important feature is that the Levoit Core 300 doesn’t use any Ultraviolet or Ion light during its purification process. This prevents the unit from producing harmful ozone or secondary pollution. 


From reading the reviews available on the internet, most users of Levoit Core 300 air purifier seem very happy with their purchase. 

Efficient, it works, well worth the money.

It can be next to my bed night and still not disturb my sleep.

I love it but it would be even better if I could control it via an app.

I can really tell the difference, especially around the cat litter trays, no more dust or smell!

Alternatives to the Levoit Core 300

Pure Enrichment Pure ZonePure Zone Air Purifier

Although this product looks very sleek, it uses UV light technology to destroy microorganisms.  While it can help how well the system works, I’ve found that this technology can, in some cases, be harmful to the environment. 

+ Energy Star Certified
+ HEPA filter
-LED indicator lights are too bright
-Not designed for large spaces

Germ Guardian 4825The Germ Guardian

This air purifier comes very highly rated. In my opinion, however, the product has been let down by its design, which I thought was pretty ugly! The purification specifications of the Germ Guardian are almost exactly that of the Core 300, but this purifier comes in more expensive.

+ 3-step filtration
+ Quiet Operation
– Faint blue UV light keeps shining through
– Doesn’t have many smart features

Four Seasons EnvionEnvion by Boneco – Four Seasons FS200

I also looked at similar products, which also have the capability of heating and cooling. This particular model is also a dehumidifier. The higher cost and larger size of such units were not really suitable for my needs. If you’re looking for a wide range of features, then this might be one to look at.

+ Space-saving 4-in-1 design
+ Includes a true HEPA filter
– No remote control
– Comes with just a one year warranty


After a lengthy search for an air purifier to help with my allergy problems when at home and work, I think I’ve now found a perfect solution. The Levoit Core 300 not only looks good, but it’s three-stage filtration system really does work and leaves me being able to breathe easily and cleanly.

The silent mode is fantastic at night time – I haven’t been disturbed a single time while leaving the unit switched on overnight. Interchangeable pre-filters for specific problems mean there is a solution to the most common air quality problems both at home and at work.

A great, affordable product that delivers precisely what it promises.
