Air purifier Filtration Methods Compared

Amaircare® Three-Stage HEPA Filtration
The three-stage filtration process employs dedicated filters, specifically designed to remove different types and sizes of contaminants. The Prefilter removes larger particulates, the HEPA filter removes sub micron particulates and the V.O.C. filter removes toxic chemicals, gases and odours.

 

• 99.97% efficient @ 0.3 microns
• Efficiency improves with use
• Lasts 2 to 5 years

 

Electronic Air Cleaners
Electronic air cleaners use high voltage to charge incoming particles which collect onto the surfaces of a series of oppositely charged metal plates.

 

ELECTRONIC
• 50% average efficiency
• Efficiency declines very quickly
• Requires frequent cleaning
• Can produce ozone

 

Electrostatic Filters
Electrostatic filters use a charged filter media which captures particulates by static attraction..

 

ELECTROSTATIC
• Efficiency drops with use
• Filters need frequent replacement

 

Ion Generators
Ion Generators use electricity to ionize particles. The ionized particles adhere to surfaces such as walls, furniture, etc.

ION GENERATORS
• Charged particulates soil walls and furniture
• Can produce ozone


HEPA vs HEPA TYPE vs Electronic


The chart compares the efficiency of three popular types of air filters: HEPA, HEPA TYPE (pleated media), and electronic air cleaners. The graph shows the average number of particles that are not captured in a typical cubic foot of filtered air. The comparison is based on continuous use.

As the graph shows an electronic air cleaner will fail to capture about half the total number of particles. A HEPA TYPE filter will fail to capture 50,000 at best. A True HEPA filter will let only 300 particles escape. If, for example, you are concerned with bacteria, which range in size from about 0.1 microns, you can see why the higher efficiency of a HEPA filter is so important.
