Rediair Air Filtration System: Clean Air On Demand

Air filtration systems are increasingly recognized as a valuable method of infection control, GAMA Healthcare describes the benefits of its adaptable Rediair system.

Environmental decontamination and hand hygiene are universally recognized as important methods to reduce the risk of infections and keep people safe. However, adequate ventilation is essential to ensure air safety in hospitals and workplaces. Aerosols and droplets carry infectious microorganisms through the air that can spread infections more easily in poorly ventilated spaces.

Effective air filtration systems can help remove these microorganisms and particles from the air by drawing air through the machine, trapping contaminants in a HEPA filter, and blowing clean air into the room.

Transmission of aerosols and droplets

We constantly release bacteria, viruses and fungi into the air around us. Pathogens like Mycobacterium tuberculosisinfluenza, RSV and coronaviruses are found in droplets and aerosols expelled when we speak, cough or even breathe, potentially infecting other people or landing on and contaminating surfaces.

Droplets are particles greater than five micrometers (µm) in diameter that typically settle within two meters, while aerosols are smaller particles (less than five µm) that stay suspended in the air longer and spread over great distances. Infectious aerosols can be inhaled, deposited on our sensitive mucous membranes or transferred to our mucous membranes by contaminated hands. There is also a risk of particles and odors triggering allergies or discomfort.

Benefits of Air Filtration

Portable HEPA filters can reduce the risk of inhaling viable pathogens in a poorly ventilated area. Unlike traditional air filtration systems found in shared spaces, portable air filtration units give you the flexibility to deliver clean air where and when you need it.

Air filtration systems can capture a variety of contaminants such as:
• Airborne pathogens (bacteria, fungi and viral aerosols);
• Fine and ultrafine particles;
• Dust;
• Mites;
• Odors; and
• Pet dander.

Air Filtration in Healthcare

Healthcare facilities such as operating theaters or intensive care units will be equipped with specialized fixed mechanical ventilation systems. However, in open wards and shared spaces, hospitals may not have effective air filtration. Installing fixed and bulky mechanical systems can be difficult. Not only are they expensive, but during installation, rooms must be emptied and closed off until they are installed, tested and ready for use. Additionally, repairs can be very disruptive to healthcare professionals and patients; if machines malfunction or break, all ventilation is lost, costing more to repair and increasing the risk of infection during downtime.

Meanwhile, COVID-19 variants like Delta and Omicron are currently prevalent. Effective air filtration in healthcare facilities is therefore essential to capture these harmful microorganisms and remove them from the surrounding air. In a recent study, Dr Andrew Conway Morris from the University of Cambridge said it was surprising how effective air filters were at removing airborne SARS-CoV-2 from wards.1

More evidence is needed to demonstrate the benefits of air filtration in reducing the risk of transmission of infectious microorganisms. Yet the importance of good ventilation is widely recognized in the discourse surrounding healthcare facilities and offices.

Find the right device for you

Choosing an air filter with the right features and functions can be confusing, as supply and infection control teams must come to terms with the language and standards associated with air purification systems. Ultimately, the effectiveness of the filtering will depend on the power of the air purifier, its filtering capacity and the volume of space in the room.

HEPA filters

HEPA stands for High Efficiency Particulate Air. HEPA H13 – H14 is considered medical grade, with HEPA 14 filtering a minimum of 99.995% of particles down to 0.3 microns in diameter. Additionally, pre-filters protect and extend the life of HEPA filters, and carbon or charcoal filters reduce unwanted odors and volatile organic compounds (VOCs).

Clean Air Delivery Rate (CADR)

Measured in cubic meters per hour (m3/h), CADR is an industry standard measure of the volume of air the air purifier can clean. The higher the number, the more efficient a device is. An air purifier with high and variable flow options will ensure adequate air changes every hour.

Patient comfort

Noise levels (dB) are an important consideration when used in a patient room. Look for a product that provides both minimum and maximum noise levels, reflecting low or high fan settings. Plus, a night mode feature mutes lights and noise to give patients a chance to rest and recover.


Designed by infection prevention experts, Rediair is a portable air purification device that captures particles as small as 0.3µm and has a CADR rate of up to 600m.3/time.

  • Dual HEPA 14 filtration

    At the heart of Rediair are two carbon composite HEPA 14 filters that work in tandem with the dual centrifugal intake fans and easy-to-clean nylon pre-filters to capture particles, odors and 99.995% of airborne pathogens. the air.

  • High clean air flow

    Thanks to its dual intake filtration system, Rediair has an exceptionally high CADR of up to 600m3/h. Despite its small form factor, a single unit provides effective ventilation for rooms up to 120m3.

  • Ultra-low noise

    Rediair is powerful yet surprisingly quiet during normal use. It has many different settings and speeds and is designed to work without causing distraction.

Nylon pre-filters, carbon composite fabric and HEPA 14 filters capture particles, expelling purified air into the room, providing up to five air changes per hour in a space up to 120 m3. Rediair’s various modes of operation allow Rediair to be used almost anywhere, from waiting rooms and offices to dental rooms.

Flexible filtration

Rediair’s dual composite HEPA 14 and carbon fabric filters decontaminate the air in a room almost instantly. Plug in, select your mode and let Rediair do the rest; It’s that simple. Adaptable to many different situations, Rediair has four operating modes to choose from:

Automatic mode

Rediair uses smart particle detection to detect air quality and automatically adjusts fan speed to effectively remove contaminants while displaying current air quality via its LED Air Quality Indicator.

Manual mode

Rediair’s manual mode allows you to adapt its operating parameters to the situation you need. By navigating through its simple digital display to select fan speeds, run times, and light modes, Rediair delivers fast, easy-to-use air purification.

turbo mode

Turbo mode spins the two centrifugal intake fans at maximum speed, dramatically increasing its CADR up to 600 m3/h, removing contaminants faster and more efficiently.

night mode

Rediair uses its built-in light sensor to monitor room light. When light levels drop, Rediair turns off all LEDs and displays and reduces fan speeds to provide near-silent decontamination throughout the night.

Rediair is an incredibly subtle air filtration system. If the internal mechanisms are complex, using Rediair is quite the opposite. The smart air quality indicator can read the ambient air quality and start decontamination within seconds of activation.
