What is an Ionic Air Purifier?

An ioniser air purifier, like other similar air purifiers, works to remove pollutants from a room or office. Others use methods such as Ultra-Violet lamps or Activated Carbon filters, and you can also find machines that use more than one method.

There are many benefits to using an Ionic Air Purifier to keep the air in your home or office fresh and healthy. People who suffer from pet or other allergies, or breathing problems, may find that an ioniser or other purifier makes a difference to their condition.

How do Ionic Air Purifiers work?

Ionized AirThink of how fresh the air smells when you’re by the coast or a waterfall. You can almost taste the difference from the normal polluted air we are forced to breathe in towns and cities. That difference is caused by the presence of negative ions.

Although the theory is as yet unproven, it is widely believed that negative ions provide benefits for our health and well-being. An Ionic Air Purifier works on the same principle as those “natural” ions produced by nature.

An ion is a particle that can either be negative or positive. Cigarette smoke, bacteria, pollen and other allergens or contaminants are positive ions. As we all know, positive and negative are attracted to each other. So the negative ions produced by an ioniser are drawn to the positive ions and effectively cancel each other out. As these “combined” particles are too heavy to remain airborne, they drop to the floor or other surfaces, and can then be cleaned. As a result of this process, the air is left in a cleaner and healthier state.

Some air purifiers use an ioniser in conjunction with a HEPA filter, in order to provide a more effective machine.

What to look for when buying an Ionic Air Purifier

As with any other product, there is a bewildering range of ionic air purifiers on the market, and the layman may find it difficult to choose the right model for their needs.

Perhaps the most important issue is that you need to choose an effective model, or you’ll be throwing your money away. There’s no point buying an air ioniser that doesn’t suit your needs or work well.

Some points to consider when browsing models, or comparing an Ionic Air Purifier to other types of air purifiers:

  • Power consumption: you will likely be running your ioniser for many hours at a time, so more power-hungry models will be expensive to run. Check the power consumption of each model. There are many models that offer low energy consumption, even when in continual use.
  • Check that it actually is an ioniser: caution should be exercised as to the country of manufacture. Some cheaper models are described as such, especially at the lower end of the market. Check to see that the model does produce negative ions.
  • Warranty: a model with a longer warranty will cover you in the case of it breaking down.
  • Output: the manufacturer should state the output of each model. This is measured in output per second. Look for a higher number. If a model does not mention its output, then it may actually be an ozone producer and should be avoided (see below for the reasons why ozone producers are not recommended).
  • Price: as with anything, if you buy cheap you may end up replacing the air ioniser within a relatively short space of time, making it a false economy and necessitating the expenditure on a better model. In that case, you may as well have spent the money on a better unit in the first place!

Ionic Air Purifiers can be a good choice if;

  • You want a quiet model. An ioniser can be a very good choice if you want a quiet machine or will be running your purifier at night. This is because they often lack a motor.
  • You live in a city, where there will be fewer negative ions in the air, as well as higher levels of pollution.
  • You want to make your home healthier. Modern homes are full of chemicals and other pollutants that can be harmful to our health, such as cleaning products, carpets, furniture and furnishings etc.
  • You do not have an allergy or respiratory disease such as asthma.
  • You have a lot of electrical equipment. Nearly everyone these days has computers, TVs, and a whole host of other electrical gadgets in their home. There is a possibility that this can be harmful to our health, or at least make us more prone to headaches and feelings of anxiety, lethargy and stress. All these gadgets emit positive ions, so an ioniser will counteract this.

Ionic Air Purifiers may not be the best option if;

  • You have allergies or a respiratory condition: this is because ionic air purifiers generally lack a filter. So, if you need a purifier because you suffer from hay fever, pet allergies, or a respiratory condition such as asthma, you should seek out a HEPA Ar Purifier, or a model that combines an ioniser with a filter.
  • You don’t want to clean the room frequently: because the machine does not take in the pollutants, but rather emits the negative ions that bind to them, those pollutants are left in the room and will settle on the floor and other surfaces. They must then be cleaned off the surfaces.

Are Ionic Air Purifiers Safe?

In the past, concerns about safety have been expressed. However, such concerns generally referred to models that produced high levels of ozone, often known as ozone generators. Continual use of these models is considered inadvisable, owing to the instability of ozone; they have actually been banned in the state of California.

Ozone generators may also be inadvisable for anyone who suffers from asthma or another respirator condition, as some find that increased exposure to ozone will make their symptoms worse. Even people who are otherwise in a good state of health may experience breathing difficulties when they are exposed to ozone.

However, ionic air purifiers are much safer. Although they do produce a small amount of ozone, this is generally within safe parameters. The FDA (Food and Drug Administration in the US) considers that ozone emissions in such equipment should be 0.05 parts per million or less. So if you purchase a model that conforms to this output, it will be safe to use.

One problem with Ionic Air Purifiers is that they don’t actually clean the air. As mentioned earlier, they work by binding the negative ions emitted to the contaminants in the air, which are positive ions. The resulting combination either settles on the floor or on other surfaces.

This means that you will still have to clean the surfaces to remove the combined particles. Cleaning will have to be carried out regularly, and anyone with allergies or health problems risks exposing themselves to the very pollutants they’re trying to remove. In this case, HEPA filters or other models that draw in the contaminants and clean them may be a better option.
