The criteria of choice not to be neglected

how to select an air purifier

The use of the device

An air purifier has a specific use. Usually, it is used to prevent the onset of certain diseases such as asthma or allergy. Other uses are also recommended such as the elimination of bad smells (pets, cat litter, kitchen smells, etc. or tobacco and chimney fumes).

In some cases, comfort and well-being are the desired goals. To have pure air in abundance is a healthy lifestyle.

The size of the device

As an appliance, an air purifier must be of the size desired by most consumers.

On the one hand, brands manufacture devices for multiple uses. On the other hand, the surfaces are different from one house to another. It is, therefore, possible that few models can meet a person’s need. Generally, an air purifier does not occupy much space. The shapes can be various: rectangular or tapered. In addition, the power of the air treatment could be different depending on these.

The desired location

The size of the device is paramount in choosing an air purifier. This is important because before buying one, it will already reflect on the desired location. In this sense, the model chosen will depend entirely on the size of the device and where it will be installed.

Several cases are possible because the location may not matter because there is enough room or you have to buy more than one air purifier. In this case, the question of power and efficiency comes into play.

The volume of the room

Several models of air purifier exist on the market. In addition, different brands offer very varied ranges that differ according to their ability to purify a certain surface. It can range from 20m² to more than 100m².

This detail is crucial as it could be used in any condition, whether at home or in an office. The latter is often more demanding in terms of volume of air delivered per hour. A flow rate around 300 m 3 / h can suffice to purify an area of ​​60 m².

Other factors to consider

The Noise

Generally, noise is measured in decibels (dB). It varies by 5 dB (corresponding to the sound of a running computer) and 60 dB (corresponding to the noise of a running vacuum) depending on the model. Manufacturers note this detail on their product, otherwise, in the user manual that goes with it.

An air purifier may consist of an electric motor with a fan. The sound level of an air purifier thus depends on the speed of the fan and the flow of exhaust air. If your device has an adjustable speed, the sound volume it emits varies depending on the speed.

The level of consumption

At the moment when it is important to fight against energy expenditure, the power consumption of the air purifier is also important, knowing that it uses an electric motor. The power needed to run this kind of devices is according to its use. With a HEPA air filter, the consumption can vary around 5 W. While models equipped with ionization filter or combustion can consume up to 90 W. However, an air purifier is often brought to operate all the time. day.

In addition, the previous criteria taken into account are also possible factors of the rise in the level of consumption (speed, air handling power, area of ​​use).

The filtration system

Currently, brands offer multi-level filtration systems. Some models have four levels of filtration, while others have only two.

The two-level models are equipped with a charcoal filter and a High-Efficiency Particulate Air filter (HEPA). On the other hand, the other four levels have a pre-filter, a charcoal filter, an antimicrobial treatment filter, and a plasma filter.

On the market, there are several types of air purification system:

– air purifiers by filtration: thanks to a HEPA filter, the particles are retained inside the device during the passage of air in the purifier. It thus eliminates impurities and bad odors.

– ionization air purifiers: these purifiers charge the air in the room with negative ions. The latter are attracted by the positive ions contained in the polluted air. Molecules thus rendered electrically negative are then deposited on the ground

– combustion air purifiers: combustion air purifiers have an air heating system that burns (200 degrees) particles, bacteria, and unwanted microbes. This type of purifier is one of the most energy consuming.

– Plasma air purifiers: Plasma air purifiers act by exciting gases (Oxygen). They generate an oxidizing molecule that is sent into the room to clean the air. The purification of the air is not done in the device but outside.

– photocatalytic air purifiers: by a process that is both physical and chemical, light (Ultra-violet) and a catalyst such as titanium dioxide (TiO2) create an oxidation and reduction reaction applied to pollutants which are then mineralized and transformed into water vapor, carbon dioxide, and nitrogen.

Some models can embed several different technologies to optimize its performance.

Maintenance of the filtration system

It is important to know how to maintain an air purifier. Some models of air purifier offer filters that are standardized and are on the market. However, some filters are washable. In this case, it is easier to maintain the device.

In addition, most air purifiers currently available on the market offer an automatic indicator of cleaning or filter replacement. This is very useful and also advantageous for a product because the quality of the air will always be maintained.
