How does an air purifier work?


With the help of a fan, the air purifier will draw the air from the room to be treated towards the device. The air drawn in then passes through the various filters to be discharged in a purified state. In order to retain physical particles, an air purifier must have a filtration system. The most important filtration system to have against allergies is the HEPA filter.

How an air purifier works

An air purifier is a device that eliminates polluting particles present in the air (pollens, animal hair, dust mites, viruses, bacteria, VOCs, dust...).

There are different types of air purifiers: the "active" air purifier and the "passive" air purifier.

Active air purifiers

Thanks to a fan, the air purifier draws air from the room to be treated towards the device. The air thus drawn in passes through the various filters and is then discharged in a purified state.

In order to retain physical particles, an air purifier must have a filtration system. It is important to take into account the quality of the filters. Indeed, the more qualitative the filters are, the more they retain a significant number of particles.

Step 1: Air filtration through the pre-filter

Placed directly on the filter cover, this water-washable foam acts as soon as the air enters the unit.

It stops macro-particles: large dust, animal hair... and preserves the life of the filtration system. To be cleaned regularly.

Step 2 : Air filtration by activated carbon

High density activated carbon beads filter and eliminate toxic gases such as formaldehyde, benzene, hydrogen sulfide, ammonia vapors, bleach, bad odors and many others.... The high concentration of activated carbon in NatéoSanté air purifiers also allows for the rapid decomposition of ozone present in your atmosphere.

Step 3: Air filtration with the HEPA filter

It retains airborne particles in the air.

The HEPA filter (Hight Efficiency Particulate Air) is a medical grade filter, also called absolute filter. We have chosen to offer you the highest HEPA classification: H14. EN1822 standard, it eliminates 99.99% of particles from 0.3µm.

Thanks to a tight weave and a precise crushing of its fibers, this filter retains: fine dust, dust mites, pollens, animal hair, diesel particles, molds, spores, fungi, pesticides, bacteria, viruses, micro-organisms.

The functions can be activated or not according to your wishes and your problem:

Step 4: Air filtration by the Photocatalytic filter

Photocatalysis: filter with titanium dioxide and a UV lamp. This process allows to keep and accumulate the energy of the UV lamp to destroy the micro-organisms, and to transform the VOC (volatile organic compounds) into H2O and CO2.

Step 5: UV lamp elimination (ON/OFF)

The UV lamp (Ultra Violet) contained in the air purifiers can kill more than 97.6% of germs and bacteria in the air.

Step 6: Negative Ion Production (ON/OFF)

More than 8 million ions per second are released. These anions allow to rebalance your environment.

Step 7: Active Oxygen Generator (ON/OFF)

This active oxygen function treats your room thoroughly while you are away. The active oxygen allows you to effectively eliminate bad odors (tobacco, kitchen, pets, body odors), dust mites, molds...

Passive" air purifiers

The so-called "passive" air purifier filters the air near the air purifier. This type of air purifiers have an average air flow rate equivalent to 14 m3/h which corresponds to the average speed of air movement by natural movement. A "passive" air purifier does not have a filtration system, they are generally simple air ionizers.

Where to buy an air purifier?

Breathe easier with an air purifier. Did you know that the average Canadian spends about 90% of their time indoors and that air pollution levels inside your home can be two to five times higher than the levels outside? Some common allergens in the home include: mold spores, tobacco smoke, dust, dust mites, dander, and pollen from ragweed, grass and trees. Mitigate the health risks associated with poor indoor air quality by using an industry certified air purifier.

How to use an air purifier

With the increase in asthma, allergies and other respiratory illnesses, more and more households are turning to air purifiers. However, an air purifier requires a number of things to consider in order to work effectively. Here are some tips on how to maximize the performance of your air purifier.

- Buy the right air purifier

First of all, don't rush into buying the first air purifier you see. If you're considering buying an air purifier, you need to identify:

The reason for its use: asthma, allergies, bad odors, pollution ...

1 - The surface of the room to be purified

Its technology: filtration, photocatalysis, plasma, combustion...

The type of filter according to your needs: HEPA particle filter, activated carbon filter to remove odors...

The CADR: it is the air renewal rate

Its noise level: especially if you want to use it in a room or a meeting room for example

Focus on the CADR

The universal indicator called CADR (Clean Air Delivery Rate), allows to compare air purifiers by measuring their efficiency. It indicates the capacity of a purifier to filter particles - smoke, dust and pollen - present in the air. You can also find the CADR measurement followed by the AHAM certification (American Association of Home Equipment Manufacturers). This is an additional guarantee of quality.

2 - Place your air purifier in the right place

One of the most important things to consider when using a purifier is its location. Ideally, the air purifier should be positioned so that clean air flows towards you. Placing the device too low or too high will result in a decrease in its performance. Also, make sure the air purifier is not placed in a confined space, for example, between two pieces of furniture or under a curtain.

3 - Close doors and windows

Many users complain that their air purifier is not working properly. This is because they find that the air quality sensors do not reflect any change in the air in the room. Unfortunately, this is often due to improper use of their purifier. Like an air conditioner to cool the air, an air purifier needs to be in an enclosed space to clean your air. So when your air purifier is on, close the doors and windows.

4 - Replace filters regularly

An air purifier is only as good as its filters. If your air purifier has a pre-filter, remember to clean it to extend the life of your filter. If it's made of fabric, it will go through the washing machine without a problem. On average, we recommend that you change the filter of an air purifier every 6 to 12 months depending on your living environment: cigarette smoke, apartment located in the city, animal hair...

The air purifier is becoming an essential product for the home and office due to the high levels of indoor air pollution. Properly maintaining your device as well as its filter and pre-filter is important and allows you to obtain a better efficiency of it.

5 - Use your purifier in your room

Do not hesitate to install your air purifier in your bedroom. Indeed, it is at night, when you sleep, that your capacity of recovery is the highest. It is therefore important to preserve your sleep and avoid coughing, sneezing and other symptoms of respiratory allergies.
