This article overview existing ionic air ionizer technology marketplace. laypersons, believe he adopt back-to-basics approach try understand technologies. dominant current trend appears creation invisible potent defence shield airborne molecular contaminants. predominant airborne threat monitored scientists world or avian flu virus.

Types Ionic Air Purifier Technologies

Broadly speaking, air purification technologies deployed er passive active modes. passive technology modes, reactive agents contained air ionizer whilst impure air drawn cleansing pushed environment. Active mode depicts proactive process bringing purifying reactive agents surrounding impure air. unusual fd combinations passive active modes ionic air puriifers.

In global market today, ionic air ionizer technologies include following categories:

(A) Ion generator - positive negative ions
(B) Ion generator - negative ions only
(C) Photocatalytic Oxidation (POC)
(D) Electrostatic filter
(E) Combos

Ion Generator - Positive Negative Ions

This combination positive negative ions appears sw mt promise future air ionizer" href="http://www.ionic-airpurifiers.com/">ionic air ionizer technology. Ty he named plasmacluster ions Sharp Corporation, Japanese corporate powerhouse tt invented them.

Positive negative plasmacluster ions actively surround harmful bacteria viruses deadly embrace. clumping occurs, hydroxyl produced. Commonly kn nature's detergent, hydroxyl powerful reactive species destroys airborne particulates removing hydrogen molecules tr organic structures. Ts chemical reaction generates harmless by-products, main water.

A differential ion generator technology, comprising positive negative ion generator powered alternate cycles control type ions generated.

Advocates positive negative ions combination claim balance ion types ps waterfalls pristine forests, i.e. real natural environment. contrast, proponents negative ions technology insist negative ions natural habitats presence positive ions harmful. far, independent scientific studies support opposing claims technologies.

Ion Generator - Negative Ions

The traditional ionic air ionizer produces negative ions. Ts technology appears he main market share currently facing challenge Sharp's plasmacluster positive negative ions technology.

It claimed nearly harmful airborne particulates le dust, smoke bacteria positive charge. Negatively charged ions naturally attracted particulates sink ground sheer weight. impurities simply removed vacuuming. Detractors negative ion technology believe "overweight" particulates ground destroyed mere act walking re-contaminates air.

tt te ws produce negative ions. crucial various methods he dt by-products, wh harmful. Te methods include:

(1) Water method - employs kn waterfall Lenard Effect. metal plate tt electrically-charged, water droplets splashed. charge splits water droplets resulting production le negative ions. harmful by-products result using water method produce ions.

(2) Electron radiation method - based single negative discharge electrode needle. simple application voltage pulse electrode results millions negatively-charged electrons bg produced. advantage ts method ozone produced. application "smaller" energy pulse.

(3) Corona discharge method - based dual electrode model, sharp metal electrode flat electrode. voltage applied electrodes. causes movement electrons electrodes ty ionising air them. criticism ts method production harmful by-products le ozone nitride oxide.

Photocatalytic Oxidation (POC)

This technology commonly applied passive mode. POC, powerful reactive agent hydroxyl key purifying process.

Germicidal ultraviolet (UV) light commonly shone catalyst (usually titanium oxide) produce hydroxyl, oxygen peroxide, wh potent oxidising agents tt vy effective destroying organic structure micro-organisms gaseous volatile organic compounds.

It claimed tt comprehensive defence POC provides main strength. Proponents technology claim POC inactivates categories indoor pollution, including:

(1) airborne particulates i.e. dust, pet dander, plant pollen, sea salts, tobacco smoke, industrial car pollution, etc

(2) bioaerosols i.e. biological compounds tt infectious contagious (e.g. pathogenic bacteria viruses) non-infectious non-contagious (e.g. non-pathogenic bacteria, molds, cell debris)

(3) volatile organic compounds (VOCs) i.e. gaseous odours chemicals - toluene, chloroform, hexane, ethanol, formaldehyde, ethylene etc, common emissions everyday products modern home.

POC technology bn criticised relying hydroxyl believed attack equal tenacity organic structures tt me molecular contaminants lung tissue, nose membranes eye cornea.

Electrostatic Filter

This technology appears originated heavy industries wh produced abundant pollutants. typical electrostatic filter ionic air ionizer includes electrodes sandwiching porous dielectric material. Dielectric materials conduct electricity metallic electrodes excellent conductors transmit receive electricity.

As impure air drawn io electrostatic purifier, passes dielectric material acts sieve. Electrostatic electricity electrodes causes airborne particulates i.e.smoke contaminants, dust, etc, stick dielectric surface. Purified air emerges purifier.

An ion source placed be electrostatic filter impart electric charge airborne particulates. impurities, charged, stick effectively dielectric material.

Criticism electrostatic filter technology focuses ozone by-product, commonly assumed produced ionisation processes.

Combo Ionic Air Purifiers

To cater various adherents critics diverse technologies, combos incorporate se types technologies. Combos include:

(1) adsorptive materials sh activated carbon oxygenated charcoal (known extremely porous surface area) added POC technology enhance removal VOCs;

(2) oxidizing catalysts le titanium oxide coated various components types air ionizers enhance VOC elimination;

(3) reducing catalysts sh manganese dioxide coated near exit outlets my air ionizers reduce reactive species ozone nitric oxide harmful;

(4) generating ions differing methods sh using microwave, UV light, radio frequency waves, direct current;

(5) tweaking specifications ionic air ionizer technology attain well-known HEPA status actually using HEPA filters.
