What is an Air Ionizer?

An air ionizer is an electrical device that ionizes air molecules when high voltage is applied to the device.It is a modern innovative technology in the field of air filters.

Today, you will find most air purifiers have a built-inionizer that entrapsdust, allergens, pollens and such other airborne particles inside the filter, thereby purifying the surrounding air.

Why does one need anAir Ionizer?

No matter how clean our home is, there are bound to be airborne allergens and dust particles in the air.Higher humidity levels further boost bacterial growth, which may be harmful for people living in the house, especially if you have kids and elderly people who may be suffering from dust allergies or respiratory problems.

To add to that, often some unpleasant odors tend to creep into the house, making the air unbreathable.An air ionizer comes to your rescue in such a case.It acts as an excellent air filter cum purifier.There are a number of advantages of having an air ionizer.

Fresh &Clean Air: Since most of us spend most part of the day indoors, either be it at home or at workplace, it is necessary that we breathe in clean air to keep us fit and healthy.Air ionizers can do the deal.Air ionizer acts as a filter and as an air purifier.Ionizers can generate the same amount of ions indoors as can be found in the fresh air outdoors.In short, they can provide you with clean, fresh air right inside the comfort of your house.

Useful for households with pets: Given that air ionizers freshen the air, they are very useful for households with pets. Air ionizers can help reduce the amount of allergens in the air, and make your indoors healthy.

Experience natural air: Air ionizers make use of negative ions to purify the air. It is believed that negative ions are present in areas such as mountains, waterfalls, rivers. Some people argue that air ionizers can provide you with fresh air, just like you would experience near a waterfall.

How does an Air Ionizer work?

Let’s briefly touch upon the functioning of an air ionizer.When voltage is applied to a series of inbuilt needles, the ionizer discharges a stream of electrons into the air.These electrons attach to the air molecules forming negatively-charged ions.The negative ions then attract positively-charged dust particles, dander, allergens,etc. in the air forming a cluster.The cluster becomes heavier and either falls to the surface or is easily sucked into the air ionizer and gets collected in the filter.The filters can be cleaned or replaced as required.

What are the different types of Air Ionizers?

Domestic Ionizers: This type of air ionizers are designed to purify stale air from the house and revitalize it to the type you would find in refreshing places such as mountains. Some domestic air ionizers are equipped with filters and fans.

Commercial Ionizers: Commercial ionizers are similar to the domestic ionizers; the only key difference is that they are equipped with a large-sized mechanical or electrostatic filter.Commercial ionizers are ideal for large commercial premises and work areas.

Personal Ionizers: There are two different types of personal ionizers.One is small and low powered, specifically created for personal breathing while travelling or at work.It can be run by electrical power source or by battery.

The other version of a personal air ionizer is a uniquely designed, wearable ionizer that can be operated by a built in Li-on battery.It is intended to emit ions and make a personal pure air zone.It is easy to carry wherever you want and you can use it conveniently anytime, anywhere.

Vehicle Ionizers: Vehicle ionizers are similar to the domestic air ionizers; the only difference is they are designed to be installed in a vehicle. They are battery operated.

Ionizers for Animals: Special models of ionizer have been manufactured for use in animal living areas such as hen coops, barns, and stables. These ionizers help to reduce airborne particles and prevent the spread of infection caused by airborne germs.

Air ionizers can also be classified based on their design.

HEPA Filtration Air Ionizers: Air ionizers equipped with filters are vastly popular.HEPA Filters or the High-Efficiency Particulate Arresting filters are capable of trapping 99 percent of air particles as fine as 0.3 micrometers or larger.HEPA Air Ionizer can clean the air off bacteria, mold spores, and smoke.Air ionizers with HEPA filters are ideal in the case of dust allergies and respiratory disorders.

Activated Carbon Air Ionizer: Air ionizers equipped with activated carbon filters are capable of absorbing odor from the air.Activated Carbon Air Ionizers are ideal in homes with pets to allow fresh, good smelling air.

Electrostatic Precipitators: Some air ionizers contain electrostatic precipitators which take in air and subject it to an electrical field.The electric charge capturesairborne particles,which get deposited on charged metal plates.Some electrostatic precipitator air ionizers have a fan.However, these air ionizers tend to emit a small quantity of ozone in the air.In case you intend to use the electrostatic precipitator in a small room, the ozone factor needs to be consideredcarefully.

What to look for when buying anAir Ionizer?

When buying an air ionizer, please check the equipment for following features and functions:

Some air ionizers are more effective than others in trapping the different sizes of airborne particles.Air ionizers with HEPA filters are good at collecting allergens and other fine particles.

Not all air cleaning technologies are good at getting rid of cigarette smoke, chemicals, and unpleasant odors.You may want to check for activated carbon air ionizers to tackle with the smoke and odor problem.

You should also check the area covered by the air ionizer.A standard ionizer can effectively cover an area upto 300 square feet.There are a number of models that can cover greater areas.You will have to measure the square footage of your room to decide which ionizer to buy.Depending upon the area needed to be covered, you can either choose a unit that can be placed on the floor or be mounted on a shelf or a counter.

The price of an air ionizer is also an important deciding factor.You may want to choose a model that is effective and affordable at the same time.Replacement cost of filters is also another determining factor.By knowing what the replacement is, you can figure out the total lifetime cost for the unit.

Depending on the air ionizer technology, some units consume more power than the others.Before settling on a model, check for its power consumption.The best power saving ionizers use 40 watts of power.

Air ionizers are supposed to run smoothly in the room without disturbing the quietness of the surroundings.However, some high power units make noise when drawing greater volumes of air.Do check for its noise making capability before selecting the ionizer so that you do not spoil the peace of your home.

What brands are reliable and available in the market for air ionizers?

In India, air ionizers are sometimes referred to as air purifiers. There are several brands that provide air ionizers, including:

Air Ionizer - Glossary of Terms:

Activated Carbon filters make use of composite carbon, which is capable of eliminating unpleasant odors from the air.

Arrestance is a measure of a filter’s capacity to trap a standard amount of test dust particles from the air entering through the filter under specific operating conditions.It is expressed as a percentage of weight.

Compact filters are indicated as a broad surface filter that contain the medium placed in 2 or 4 Vdesign to gain a larger filtration surface and increase the dust holding capacity.

Electrostatic filter consists of electrically-charged plates that attract electrically-charged airborne particles passing through them.

Grease Filters are designed for use in kitchens.Along with air purification, these filters collect the grease and grime released during cooking.

Mechanical filtration uses the method of trapping particles by passing them through gaps in fibers of a media.

Safe change system is a filter housing assembly, which enables changing of filters inside a protective system. The safe change system prevents captured dust particles from releasing back into the air.Safe change system is very important when dealing with the filtration of harmful and toxic particles.
