Product Description

IQAir CleanZone SL Airmid Report

The IQAir CleanZone SL is a stand-alone air filtration system engineered for applications that demand high-volume removal of particulates, gases, and chemicals while maintaining minimal noise levels.

With an exceptional airflow capacity of up to 820 m³ per hour of HEPA filtered air, the IQAir CleanZone SL is designed to provide HEPA clean air in various environments that lack or have inadequate ventilation. The CleanZone SL excels at delivering a larger volume of clean air while operating at significantly lower sound levels compared to other stand-alone commercial air filtration systems. The unit is versatile, reliable, and suitable for the most sensitive environments. 

The effectiveness of the IQAir Cleanzone high-performance air purifiers in controlling viruses has been officially confirmed by the European accredited test institute Airmid Healthgroup in Ireland. The attached test report confirms that the IQAir high-performance air purifiers achieve a 99.9% reduction of airborne viruses in less than 10 minutes in a room of nearly 30m3.  On the highest speed setting, the viral load was reduced from above 2790 ng/m3 to below the detectable measure of 0.156 ng/m3 - a 99.99% reduction.  The test used the H1N1 virus, which is identical in size range to SARS-CoV-2.

High Airflow

The IQAir CleanZone SL boasts an impressive airflow capacity of 820 m³, meeting stringent noise standards while delivering HEPA air filtration. This airflow surpasses that of most professional standalone air filtration system at such a low noise level. Air is drawn in from the bottom of the IQAir CleanZone SL system and directed upward to avoid drafts if positioned in a vertical direction.  The unit can also be wall-mounted horizontally.

Exceptionally Quiet

No other professional HEPA air purifier we've tested comes close to matching the quiet, unobtrusive operation of the IQAir CleanZone SL/SLS. Two aerodynamically designed radial fans enable the IQAir CleanZone SL to move large air volumes with minimal vibration and turbulence, preventing drafts.

The IQAir CleanZone SL features a sound-reducing post-filtration design that silently and efficiently directs air into the environment, generating minimal noise.

Infection Control

A recent study by the European accredited test laboratory Airmid in Ireland showed that the IQAir CleanZone reduces viral concentrations by over 99.9% in less than 10 minutes in a 28.5 m3 room. While these results cannot be translated directly to larger occupied spaces, the test with sophisticated laser particle counters has shown, that 2-3 air changes per hour of a room’s air volume can lead to a 70-90% reduction of airborne particulates. This is significant because even a 50% reduction in viral load in a room reduces the risk of infection significantly. 

Compact Design

The slim, 25cm depth of the IQAir CleanZone SL minimizes floor space requirements. It can be wall-mounted, placed on the floor, or even ceiling-mounted in space-limited applications.

If mobility is needed, the IQAir CleanZone SL/S can be equipped with casters. 

The IQAir Cleanzone SLS can also be offered with an 'art-cover.' The cover comes in Oak or Mahogany finish, suitable for both mobile and wall-mounted units. These covers are made in Switzerland from veneer wood panels.

Pollution Control

The HEPA filtration media in the IQAir CleanZone SL removes over 99% of particles down to 0.3 microns and is proven to filter ultra-fine particles down to 0.003 microns.

The IQAir CleanZone SL filters:

  • Viruses (including MRSA, SARS-CoV-2)
  • Bacteria
  • General Fine Dust
  • Traffic Pollution
  • Mould Spores

The IQAir nano-fiber filtration technology used in the IQAir CleanZone SL allows more air to pass through the filters than conventional filters, an impressive feat considering the unit's ultra-high filter efficiency.

Gas and Odour Control

The IQAir CleanZone SL, when fitted with its silencer unit, can incorporate gas and odour control filtration in addition to high-quality particulate filtration. This makes the IQAir CleanZone SLS a versatile solution for various air contamination problems, restaurants, gyms, research facilities, and more.

Filtration Technology

Optional Gas Cartridge Technology

The IQAir Cleanzone SLS can be equipped with optional granular carbon cartridges designed for gas and chemical removal. These four GCX filter cartridges are engineered to accommodate gas phase filtration media, with a capacity of up to 14.6 kg. These cylindrical cartridges are designed to optimize interaction between contaminated air and the filter media, ensuring the highest level of removal efficiency. Thanks to their generous surface area, these cartridges can sustain very high airflow rates.

Five different broad spectra of gaseous medias are available for controlling gases and odors:

GCX VOC: Designed for higher molecular gaseous pollutants, including a variety of odor-causing organic compounds (e.g., dimethylamine), VOCs (e.g., benzene, toluene, xylene), solvents (e.g., cyclohexane, carbon disulfide, turpentine, trichloroethylene), alcohols (e.g., methanol, propanol), aromatic hydrocarbons (e.g., naphthalene, styrene), alkenes, esters (e.g., ethyl acetate), and ozone, etc.

GCX ChemiSorber: Suitable for a broad range of chemical pollutants, including many lower molecular aldehydes (e.g., formaldehyde) and organic acids (e.g., acrylic acid, acetic acid), sulfuric oxides (e.g., sulfur dioxide, sulfur trioxide), and nitrogen oxides (nitrogen monoxide, nitrogen dioxide), etc.

GCX MultiGas™: Effective for a wide spectrum of gaseous pollutants and odors, including hydrocarbons, VOCs, sulfuric oxides, formaldehyde, hydrogen sulfide, lower molecular aldehydes and organic acids, nitrogen oxides, higher molecular gases, odors, ozone, etc.

GCX AM: Specifically designed for ammonia, amines (e.g., methylamine, triethylamine), etc.

GCX AcidPro™: Ideal for sour gases, including caproic acid, caprylic acid, chlorine, formic acid, hydrobromic acid, hydrochloric acid, nitric acid, dinitrogen monoxide, sulfuric acid, etc.
