About different air cleaning systems, pros and cons and applications

• Ultraviolet (UV) Air Cleaners

• Ozone Air Cleaners

• HEPA Air Filter

• Plasma Ionization

Ozone is the unstable molecule of three Oxygen atoms (O₃).

Ozone can be generated by an electrical process.

Ozone can be an effective way of eliminating odors, chemicals and mold.

Too much Ozone can be a health hazard.

HEPA Air Filter:
High Efficiency Particle Arresting (HEPA) filters are made of paper or polymer that is densely packed to reduce the air flow and stop particles from entering the air stream.

HEPA filters are often used in hospital or clean room environments but they are not well suited for homes or commercial spaces because of the limitation on air flow that results from these filters.

HEPA filters need to be changed quite often due to their construction and restrictive air flow characteristics.

Plasma Ionization:
This ionization will effectively remove odors and gases. The level of elimination varies depending on type of gas and odor.

The tubes which are manufactured of glass are expensive and can be dangerous to handle. They must be replaced at regular intervals - once a year since they will not function if soiled.

With regular service maintenance, life cycle costs are high. Some units have no alarm functions for malfunctioning tubes.

In addition, regular service maintenance is required, since their function will fail if soiled.

Some units have no alarm function for tube malfunctioning.

Plasma ionization will reduce, according to several research findings, the content of many volatile organic and chemical substances (several of which give a bad smell) in the air by breaking up molecules into smaller constituents.

The plasma ionization technique is also reported to neutralize harmful bacteria, viruses and allergens by destroying their surface structure by chemical means. (To a certain extent plasma ionization is likely to create cluster ions in the same way as negative ion generation and it has therefore also a particle reducing effect.

Tube ionization emits ozone.
