How to choose an air ionizer – tips of experts

Air ionizer – a device that produces ions with negative charge. The device creates a feeling of fresh air and reduces the negative impact of technology on the human body.

We recommend that you read the rating of the best ionizers for home and the best air purifiers for an apartment.

What is an ionizer for? What problems does it solve device?

Before buying a device, you should determine the scope of tasks, with which he must handle:

  1. improvement of well-being,

  2. air purification from odors,

  3. removal of allergens and dust.

To solve each of these problems, its own type of ionizer.

For those who want to improve their health, the apartment model designed to accommodate a smaller area. During her work there will be no smell of ozone.

You can remove tobacco smoke and other odors with the appliance, emitting large amounts of ozone. Good with the task Dealing with devices equipped with electrostatic filters. IN unlike ionizers with replaceable filters, which are fast clogged, devices with electrostatic filters are easy to maintain: they do not require fixed costs and wash well.

Those who need to get rid of allergens and dust should pay attention to devices equipped with a HEPA filter. During the work of such ionizers not only cleans the air well, but also almost no smell of ozone. Therefore, these devices are suitable for children’s rooms.

Types of ionizers and their features

All ionizers can be divided into 2 main groups:

  1. unipolar

  2. bipolar.

Unipolar Ionizers

Unipolar ionizers

The main feature of this group is the development of only one species particles (negatively or positively charged). Exist the following types of unipolar devices:

  1. water (not only ionize the air, but also saturate it particles of water)

  2. corona (ionize particles entering the device due to characteristic “hit”),

  3. plasma (ionize and purify the air at the same time),

  4. ultraviolet (eliminate odor and dust with ultraviolet rays)

  5. thermal (air ionization occurs due to heating gas).


  • compactness

  • killing viruses that are mostly charged positively.

  • profitability


  • only one type of ion is produced,

  • Nitrogen compounds are released.

Bipolar ionizers

Bipolar devices simultaneously emit particles with positive and negative charge.


  • lack of release of nitrogen compounds.

  • lack of electrostatic field in the room.

  • the production of a small amount of ozone,


  • high price.

Noise level

Depending on the noise level that the device emits, all ionizers can be divided into 2 types:

  1. equipped with a fan

  2. based on the principle of ionic wind.

Ionizers with a fan

Ionizers with a fan

Such models are suitable for people who can not stand outsiders smells.


  • almost complete absence of ozone odor.


  • significant noise level.

Ionizer based ionizers

Such models will appeal to those who react poorly to outsiders sounds.


  • work almost silently.


  • emit large amounts of ozone, the smell of which is felt in in the air.

The choice of device depending on the area of ​​the apartment

choice of ionizer depending on the area

Before buying a device, you need to calculate the area that it will ionize. Families of 2-3 people suitable models designed to clean indoor air, appropriate to the size of the available housing. In this case there will be the optimum level of anions and ions has been reached.

Large families who live in small houses or apartments It is necessary to choose models designed for larger premises. IN In this case, air purification will be better.

Please note that minimum performance standards ionizer for a negative charge should be at least 1,500-3 000/400 particles / cm3, and for the positive – 3 000-5 000/600 particles / cm3. At the same time, the polarity indicators must be in the range of -0.5-0 for negative and -0.2 positive ions.

Important technical characteristics of ionizers

When choosing a device, you must pay attention to:

  1. amount of produced negative ions (recommended the norm is from 600 to 50,000 particles per 1 cm3),

  2. the area of ​​the room for air purification in which it is designed appliance

  3. permissible distance from the ionizer to the person (not less than 1 m)

  4. the number of produced ozone molecules (the lower this parameter, the better, the maximum value should not exceed 0.1 mg / m3)

  5. type of filter

  6. case material (high-quality plastic or wood),

  7. the presence of a fan,

  8. evaporation rate (the size of this parameter depends on indoor humidity level: for apartments with low humidity a device with an evaporation rate of up to 400 ml / h, with an average humidity (40%) – 250 ml / h, with high humidity – 60 ml / h).

Extra options

Devices can be equipped with:

  1. remote control

  2. timer on or off, which allows you not to follow after the operating time of the ionizer,

  3. indicator of the pollution status of the device, which signals the need for cleaning.

Filter selection

select filter

Many ionizers not only saturate the air negatively charged particles, but also remove dust, allergens, pollen from it and other impurities. For this, these types are used. filters:

  1. electrostatic,

  2. HEPA filter

  3. reticulate,

  4. carbonic,

  5. photocatalytic.


The filter is a positively charged grid equipped with negative charge element. When passing through the grate dust particles receive a positive charge and are attracted to negatively charged element.


  1. durability,

  2. Ideal for smoking rooms.


  1. emits large amounts of ozone,

  2. not suitable for living quarters.

HEPA filter

The best solution for allergy sufferers.


  1. purifies air from the smallest fractions of dust and other negative impurities.


  1. must be changed once every six months or a year.


The filter is a fine mesh that protects sand and wool ionizer.


  1. inexpensive,

  2. protects the device from failure.


  1. does not cope with a full air purification.


A great solution to eliminate odors.


  1. ecologicaly clean,

  2. Suitable for both apartments and public spaces.


  1. can’t cope with lung air purification compounds.


The filter purifies the air using ultraviolet radiation, under the effect of which all impurities are neutralized.


  1. most effective among the listed filters.


  1. high price.

Ionizer Care

The efficiency of ionizers depends on the cleanliness of the needles and filters. Electrostatic filters should be cleaned. under running water or wipe with a damp cloth every day. Devices with HEPA filters must be vacuumed once a month. IN an ionizer with a humidification function should change the water at least once every day. It is also necessary to clean all containers.


The ionizer must have all the necessary documents: technical and hygiene certificates, instructions, warranty card. These paper will be needed in case of detection of device mismatch declared characteristics or to carry out repairs.
