Viruses and bacteria in the air we breathe

The air we breathe can contain viruses, bacteria, and mold that are potentially harmful to our health. These microorganisms spread easily through droplets emitted by breathing, coughing, or sneezing, which are classified as:

• Droplets: Larger particles that quickly fall to the ground.
• Aerosols: Smaller particles that remain suspended in the air for extended periods, increasing the risk of transmission, particularly in enclosed and poorly ventilated spaces.

Respiratory viruses, such as flu and SARS-CoV-2, use these methods to spread, but they can also be transported through contaminated water drains or ventilation systems.

Bacteria also travel through the air in different ways:

• Environmental: Naturally present in air, water, and soil.
• Person-to-person transmission: Spread through respiratory secretions.
• Dust particles: Some bacteria attach to dust or organic residues, remaining suspended in the air and contributing to disease transmission.
• Contaminated surfaces: Touching infected surfaces and then touching the face can facilitate infection.

Mold, often found in humid and poorly ventilated environments, should not be underestimated as they can cause respiratory issues and compromise air quality. Proper ventilation and good hygiene practices are essential to reducing exposure risks to these pathogens.

Beyond microorganisms, indoor air can contain pollutants such as volatile organic compounds (VOCs) and fine particulate matter (PM2.5 and PM10), which can irritate the respiratory tract and cause long-term health problems. Keeping indoor air clean is crucial for overall well-being.

Consequences of breathing polluted air

Prolonged exposure to contaminated air can have both short- and long-term health effects, depending on the duration and intensity of exposure.

Short-term effects:

• Irritation of the respiratory tract, causing coughing, sore throat, and shortness of breath
• Red, watery eyes
• Headaches and dizziness
• Worsening of allergies and asthma
• Fatigue and reduced concentration

Long-term effects:

• Chronic respiratory diseases such as chronic asthma and bronchitis
• Cardiovascular diseases, increasing the risk of hypertension, heart attacks, and strokes
• Cognitive problems, with an increased risk of neurodegenerative diseases

Children and the elderly are the most vulnerable to indoor air pollution, facing a higher risk of developing adverse effects.

The benefits of air purifiers

A high-quality air purifier can significantly improve daily well-being. Thanks to advanced technologies, it effectively reduces airborne viruses, bacteria, and molds, lowering health risks and creating a safer environment. Additionally, it helps combat allergens such as pollen, dust mites, and pet dander, providing relief to allergy sufferers.

Breathing clean air also positively affects quality of life by reducing fatigue, improving sleep, and enhancing concentration and productivity. Mental well-being benefits as well, as healthier air helps reduce stress and improve mood, making indoor spaces more comfortable and pleasant.

How Vitesy air purifiers work

Vitesy has developed innovative air purification solutions that ensure effectiveness and sustainability.

Vitesy purifiers use photocatalytic technology, which not only captures pollutants but actively eliminates them.

• Photocatalysis: A natural process activated by visible light LEDs positioned above a photocatalytic filter coated with an optimised nano-material. Photocatalysis can be compared to photosynthesis: just as plants transform carbon dioxide into oxygen through light, Vitesy's air purifiers transform water and oxygen in the air into compounds that neutralise impurities.

Vitesy products combine photocatalysis with additional technologies to maximise performance:

• In Natede, photocatalysis works alongside phytoremediation, a natural process that leverages the ability of plants to purify air and water by absorbing and neutralising pollutants through their roots and leaves. Thanks to the combined action of the plant and microorganisms in the soil, harmful substances like VOCs, fine dust, and other pollutants are trapped, transformed, and broken down into harmless elements.

• In Eteria, photocatalysis is enhanced by a mechanical pre-filter that captures particulate matter (PM), keeping the filter efficient over time. The pre-filter is also machine washable, ensuring easy maintenance and prolonged performance.

Our purification technology uses nano-materials to generate free radicals when interacting with oxygen and humidity in the air. This process effectively neutralizes microorganisms (viruses, bacteria, mold) and chemical compounds such as VOCs, odors, and nitrogen oxides.

These systems have been tested against the SARS-CoV-2 virus, demonstrating over 99% effectiveness in its elimination.

Filter-free purification technology

Vitesy air purifiers offer an ecological and practical alternative to traditional HEPA filter systems. While HEPA filters require periodic replacements, leading to additional costs and waste, Vitesy devices use a washable and reusable ceramic photocatalytic filter, eliminating the need for disposable filters. This approach reduces environmental impact while providing long-term savings.

Eteria and Natede: efficiency without compromise

Both Natede and Eteria use photocatalytic purification technology and feature a dual purification process, but they have some key differences.

Eteria: the compact and smart air purifier

Eteria is a practical and compact personal air purifier, ideal for those seeking a versatile, low-maintenance solution. With its fabric pre-filter, it captures dust, pollen, and pet hair, improving air quality in any environment.

• Portable and convenient: Easily moved between rooms, such as from the living room to the kitchen to eliminate cooking odors.
• Smart monitoring: A network of intelligent modules analyzes air quality in multiple spaces for targeted purification. Real-time data on temperature, humidity, tVOCs, and CO2 levels is available via the Vitesy Hub app.
• No filter replacements: The photocatalytic filter is washable, avoiding extra costs and waste.
• Advanced technology: Photocatalysis and nanotechnology eliminate pollutants at a molecular level, transforming them into harmless substances.
• Compatible with voice assistants: Can be managed via Alexa, Google Assistant, or the Vitesy Hub app.
• Perfect for any space: Ideal for homes, offices, hotels, and other indoor spaces. With a USB-C port, it can even be used on a desk while working.

With its fast purification rate, Eteria improves air quality in medium-sized rooms (15-20 m²) in under 90 minutes, ensuring a healthier environment efficiently and sustainably.

Natede: the air purifier that harnesses the power of plants

Natede combines photocatalysis with the natural purifying power of plants. Harmful substances are trapped in the soil and transformed by microorganisms into nutrients for the plant, ensuring comprehensive purification. Ideal for plant lovers, it requires more attention in plant care and device maintenance.

• Natural and technological purification: Combines plant filtration with photocatalysis to eliminate pollutants.
• Smart monitoring: Provides real-time data on temperature, humidity, VOCs, CO2, and PM2.5 levels.
• No filter replacements: Pollutants are eliminated at a molecular level through a chemical reaction activated by visible light LEDs. The filter only needs rinsing under running water every two months.
• Efficient and powerful: Purifies a medium-sized room (15-20 m²) in under two hours.

With Natede Smart, you can improve air quality in an innovative and sustainable way, merging technology and nature for healthier breathing every day.
