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.
- S99.97% efficient @ 0.3 microns
- Efficiency improves with use
- Lasts 2 to 5 years
- Can be mild, moderate or severe
- Can vary from person to person
- Can flare up from time to time and then not appear for long periods
- Can vary from one episode to the next
Electronic air cleaners use high voltage to charge incoming particles which collect onto the surfaces of a series of oppositely charged metal plates.
- 50% average efficiency/li>
- Efficiency declines very quickly
- Requires frequent cleaning
- Can produce ozone
- Efficiency drops with use
- Electrostatic filters use a charged filter media which captures particulates by static attraction.
- Filters need frequent replacement
Ion Generators use electricity to ionize particles. The ionized particles adhere to surfaces such as walls, furniture, etc.
- Charged particulates soil walls and furniture
- Can produce ozone
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.
