Copied Website URL
This article is a complete and extensive comparison of the latest air purifiers from brands including Dyson, Panasonic, Sharp, Phillips, and Clair, helping you decide which model works best for you.

In addition to having positive eating and exercise habits, intaking good air quality is an important aspect of staying healthy. Although this may seem insignificant, studies conducted in Hong Kong have found that the air quality in some homes is inferior to the air quality outside. How do you prevent this from happening? Get an air purifier. With hundreds of different styles and types, it can be difficult to choose the air purifier fit for your home. This article will help guide you in choosing the air purifier best for you. 

Clean Air Volume (CADR Value)

Most air purifiers provide a reference value called CADR (Clean Air Delivery Rate). This value, agreed upon by US appliance manufacturers, refers to the speed at which the air purifier removes different pollutants. The higher the value, the quicker the purification of the pollutant. Purifiers have different speeds for different contaminants, making it important to compare the different purification speeds when choosing your air purifier.  

Available Room Size

In addition to the CADR value, manufacturers will indicate the purification capacity of their purifiers relative to the available room size. If you only need the purifier for a small room, a mini table purifier may do the job. If you need one for a larger hallway, a large air-purifier will be more suitable. 

Cleaning Method

Air fresheners have different air cleaning methods, allowing consumers to choose an air freshener according to the cleaning method that best suit their needs.
  • HEPA filter: Made out of fiber, the HEPA (High-Efficiency Particulate Air) it the most common and widely used filter on the market. Its ability to filter 99.7% of the finest 0.3μm particles and up to pollutants as small as 2.5 micrometers. The downside is HEPA filters don’t filter odors, and most of them can’t be washed.
  • Activated carbon filter: This filter, known as the activated carbon filter, can be used to eliminate odors and volatile organic compounds, but is unable to filter dust.
  • Negative ions: Some air purifiers release negative ions into the air that bind with odor molecules, thus chemically reacting into ordinary water and carbon dioxide. At the same time, it will charge floating particles in the air, and when they attract each other, they will fall to the ground and become dust. Negative ions are often used with HEPA filters.
  • Photocatalyst: This method uses ultraviolet light to illuminate the air, encouraging the bacteria to decompose organic matter. However, its decomposition rate is slow, therefore its effect is relatively limited.


The sound of an air purifier is an unavoidable aspect. In general, the higher the CADR value the noisier the machine. Directly listening to the air purifier is the best way to determine whether or not the noise is bearable. 


A variety of functions available on air purifiers make it more convenient and easy for users。Common features include:
  • Sleep Mode: The air purifier can continue operating at night with minimal operation sound, not affecting the sleep of the user.Wi-Fi
  • Wi-Fi Function: Users can download a mobile phone application to check the filter life of their air purifier. In addition, applications come with controls that make operating your air purifier easier. 
  • Automatic Mode: The air purifier can automatically sense the air quality and activate certain functions to clean the air. 
  • Air Quality Display: Some air purifiers are equipped with display lights that indicate the air quality of the environment.
