Air purification
AIR PURIFIER
The main mission of an air purifier is to eliminate domestic pollution to offer you a healthy environment. It acts effectively against fine particles (PM2.5), allergens such as pollen, dust, and dust mites, as well as gaseous pollutants like VOCs (formaldehyde) and bad odors. Some models, thanks to advanced technologies, are also capable of filtering viruses and bacteria, playing a key role in health prevention (flu, Covid-19).
To choose the right device, the first criterion is room volume. It is crucial to adapt the model's power to the surface area in m² to be treated to ensure optimal air renewal (at least 3 times per hour). Next, define the specific usage: bedroom, living room, or office. Take your environment into account: thick curtains, carpeting, or the presence of pets (dogs, cats) increase the concentration of hair and dander, requiring more efficient filtration.
Finally, the location of your home influences the choice of filter. An urban apartment located near a busy road will require increased filtration against exhaust fumes and diesel particles, unlike a house in the countryside where pollen will be the priority target.
There Are Several Technologies for Purifying Indoor Air:
Particle Filtration (HEPA):
This is the market standard. Air is drawn in through a series of filters (pre-filter, HEPA filter). This very fine mesh captures 99.97% of ultra-fine particles. Often coupled with an activated carbon filter, this system also neutralizes VOCs, smoke, and cooking odors. This mechanical technology, with no harmful emissions, is recommended by Anses (French National Agency for Food, Environmental and Occupational Health & Safety).
Negative Ionization:
This process releases negative ions into the ambient air to rebalance the atmosphere. Through an electrostatic effect, these ions attach to suspended pollutants (positively charged). Weighed down, the particles fall to the ground and are no longer inhaled. It is a silent technology that provides a natural sensation of freshness.
UV Lamp or Photo-Catalytic Filter:
This method aims to destroy pollutants by breaking their molecular structure via UV rays projected onto titanium dioxide. Although appealing, this technology degrades pollutant DNA but can release potentially irritating by-products (cyanides, ketones). As a precautionary measure and following Anses advice, we do not recommend this process for domestic use.
At Air and Me, we prioritize safety and performance. You will find a wide range of air purifiers using certified HEPA filtration, sometimes combined with negative ionization for maximum efficiency. In accordance with health recommendations, we do not sell devices with photocatalysis or UV lamps that emit harmful by-products.

PROFESSIONAL AIR PURIFIERS
Air quality at work is a lever for well-being and productivity. The use of a professional air purifier meets specific constraints: large volumes (open spaces), high footfall, or exposure to chemical products (hair salons, nail bars, workshops). Beyond power, criteria such as noise level, smart programming, and robustness are essential for working serenely without auditory nuisance.
MEDICAL AIR PURIFIERS
Healthcare facilities (dental offices, waiting rooms, nursing homes) require impeccable hygiene. Medical-grade purifiers offer superior viral and bacteriological filtration capacity. For these public-facing spaces, we offer secure models with wall-mounting options. This optimizes space, makes floor cleaning easier, and prevents any risk of theft or accidental falls.

-
1. Pollutant Removal:
Air purifiers are designed to capture and eliminate various pollutants present in indoor air, such as dust, pollen, mold spores, and fine particles (PM2.5). This is particularly useful for people with allergies or asthma. -
2. Odor Reduction:
Purifiers equipped with activated carbon filters can absorb unpleasant odors caused by cooking, pets, tobacco smoke, or other sources, improving the overall smell of your living space. -
3. Reduction of Airborne Particles:
Some air purifiers can capture bacteria, viruses, and other pathogens, reducing the risk of airborne diseases. -
4. Improved Quality of Life:
By purifying the air, these devices can reduce eye, nose, and throat irritation and help prevent headaches and fatigue caused by poor indoor air quality. -
5. Respiratory Comfort:
For people with chronic respiratory conditions, like chronic bronchitis or COPD, an air purifier can provide relief by reducing the concentration of irritating particles in the air. -
6. Neutralization of Volatile Organic Compounds (VOCs):
Some purifiers can also reduce VOC levels, toxic gases emitted by chemicals in paints, cleaners, and other household products.
In summary, an air purifier not only improves indoor air quality but also contributes to the health and well-being of occupants by reducing pollutant concentrations and creating a healthier indoor environment.
Here’s an overview of the main technologies used to purify indoor air, with their advantages and disadvantages:
HEPA (High-Efficiency Particulate Air) Filtration
1. Advantages:
- 1. High Efficiency: HEPA filters capture 99.97% of particles as small as 0.3 microns, including dust, pollen, mold spores, and some bacteria.
- 2. Durability: HEPA filters have a long lifespan when properly maintained.
2. Disadvantages:
- 1. Noise: Purifiers using HEPA filters can be noisy due to the powerful fans required to push air through the filter.
- 2. No Gas Removal: They do not capture gases or volatile organic compounds (VOCs).
