It’s important to mention that it uses high-quality filters, like the HEPA-Pure filters that are able to capture even microscopic particles. The filtration system has two layers of sealed filtration that retain particles down to 0.3 microns in size. This device even generates negative ions that clear the air of impurities and bacteria. Moreover, it allows you to opt for automatic operation, more precisely it uses a sensor that will automatically adjust the speed of the fan according to present air quality conditions in the room for optimal performance.

The first thing that you will notice is its design and mainly its size. It is large compared to other models in its price range, but this is understandable considering that it is the best air purifier for basement at the moment. Thus, as it can cover a wider area and is able to pick up more particles from the air, the plus-size is advantageous in the end. These are some of the design characteristics:

  • Intuitive controls are labeled clearly so that you won’t struggle to choose various settings or to adjust air filtering capabilities.
  • You can choose to turn off all the controls and indicators so that it won’t bother you during the night.
  • Despite its size, it is a fairly quiet appliance, although it may become a bit loud if you keep it on high speed for a long amount of time.

If you seek truly silent air purification and you plan on using the system in the baby’s room or bedroom, spaces that are generally small to medium-sized, we recommend you opt for a nursery air purifier rather than this model.
