The greatest risk indoors is what you can’t see.
Today, our lives are surrounded by mechanical ventilation systems.
Every hour, more than 100 billion cubic metres of air may pass through air handling systems worldwide.
This air reaches our living spaces through a closed system.
Outdoor “fresh” air is already polluted, and once it enters air handling units, the technology involved can further contaminate the ductwork.
As a result, bacteria, fungi and other pathogens can continuously pose a risk to our health.

Meet LaraSystems
The first device that disinfects an entire duct network.
Automatically.
Automatically.
LaraSystems is a smart disinfection system for the 21st century, featuring a unique, patent-pending technology, the first of its kind in the world. The Lara product family is an innovative ventilation hygiene system that automates the disinfection of the internal surfaces of air handling units and ventilation ducts.
Innovative Disinfection
-
Deep disinfecting method: The Lara System uses atomized disinfection to reach every corner of a duct network.
-
Broad-spectrum effect: Its unique, specialized spray nozzle produces a complete droplet spectrum ranging from 0 to 160 µm, enabling a single application to perform multiple functions simultaneously. Following the airflow, the droplets reach and settle in the same areas where airborne microbiological contaminants may also accumulate.
Health Benefits
-
Indoor wellness: By eliminating fungi and bacteria at the source, it reduces common flu-like symptoms and allergies.
-
Sustainable approach: Compared with physical air-duct cleaning, LaraSystems provides the advantage of repeatable, automated hygienic treatment without manual intervention. Its sustainability benefits come from reducing emergency interventions, service visits, and downtime, while making the use of water, energy, and disinfectant more predictable.
The system operates for only around 5.5 hours per year, during which it uses approximately 52 litres of water per duct, while its energy consumption is lower than that of a small household appliance.

What is Lara Systems?
The Hidden Problem in the Air
We all know the atmosphere can be full of pollutants.
But here’s the reality: bad air isn’t only outside. It’s also inside your offices, shopping centers, and even homes. And it’s a different kind of problem.
Polluted air in the atmosphere
-
Particulate Matter: Small particles that damage lungs
-
Carbon dioxide: traps heat, drives climate change
Polluted air in our living spaces
-
Bacteria, viruses: Harmful bacteria (e.g. Legionella) and viruses (e.g. Coronavirus) can cause respiratory problems
-
Fungi: Allergic reactions, fatigue, headaches , long-term health issues
The Role of Duct Systems
Think about duct systems: the ventilation networks in office buildings, malls, supermarkets, and sometimes homes. Their job? To circulate and refresh indoor air. However, because these systems are enclosed, they can also become breeding grounds for unwanted contaminants.
Contaminants in Duct Systems
-
Dust accumulation: Dust can gather over time, reducing airflow efficiency and worsening air quality.
-
Microbial growth: Moisture trapped inside ducts allows bacteria, mold, and fungi to thrive on interior surfaces.
Health and Maintenance Concerns
-
Respiratory effects: Polluted ducts can circulate allergens and irritants, leading to allergies or breathing issues.
-
Regular inspections: Routine cleaning helps prevent buildup and maintain a healthy ventilation system.
A Breeding Ground for Illness
Inside neglected duct systems, fungi and bacteria can thrive. In fact, studies show that these microorganisms are responsible for up to 42% of illnesses we commonly call ‘the flu.’ When ducts are not properly cleaned, they become silent carriers of disease.
Microbial Growth and Spread
-
Ideal conditions: Warmth, humidity, and organic dust inside ducts create breeding environments for microbes.
-
Airborne transmission: Once active, these microorganisms spread quickly through air, reaching all rooms.
Building-Wide Contamination Cycle
-
Recurrent outbreaks: Contaminated ducts recirculate pathogens, leading to repeated illness cycles among occupants.
-
Cross-zone impact: Shared ventilation means one infected area can quickly compromise entire floors.
Cleaning Frequency Matters
Best practice recommends cleaning and disinfecting these systems every month. More responsible building managers often do it annually. The less responsible ones? They don’t do it at all, leaving people exposed to preventable health risks.
Maintenance Frequency
-
Monthly cleaning: Regular disinfection ensures better air quality and prevents biological buildup in high-traffic buildings.
-
Annual cleaning: Common compromise among managers, balancing cost and hygiene while still minimizing health risks.
Long-Term Building Impact
-
Equipment life: Clean ducts prevent strain on ventilation motors and fans, reducing the need for costly replacements.
-
Compliance: Proper sanitation aligns with workplace safety and public health guidelines, promoting trust and credibility.
The Lara Solution
Lara Systems was developed to put an end to this hidden hazard. With advanced disinfecting technology, it disinfects duct networks thoroughly, stopping the spread of illnesses and ensuring healthier indoor air in homes, workplaces, and public buildings.
Innovative Disinfection
-
Deep disinfecting method: The Lara System uses atomized disinfection to reach every corner of a duct network.
-
Broad-spectrum effect: It targets bacteria, and fungi, leaving minimal residue and no toxic byproducts.
Health Benefits
-
Indoor wellness: By eliminating fungi and bacteria at the source, it reduces common flu-like symptoms and allergies.
-

Disinfectant
LaraSystems devices are automated air-duct disinfection systems designed to integrate into an existing air-handling unit and ductwork network. It atomizes a mixture of mains water and Sanosil Super 25 Ag, a hydrogen peroxide-based biocidal solution, directly into the airflow. Treatments can be scheduled in advance, operated individually for each duct, and fully logged.
Swiss-based Sanosil has been developing hydrogen peroxide-based disinfectants for more than 40 years. Its products are used in more than 30 countries worldwide, including in healthcare, pharmaceutical, laboratory, and food-industry environments. During the disinfection process, hydrogen peroxide breaks down into water and oxygen. The automated LaraSystems solution atomizes the disinfectant at a 5% dilution.
