CleanZone® SL Series

The strong, silent type.

The CleanZone SL combines high performance with ultra-low noise.

Highly effective against ultrafine particles

Ultrafine particles (UFPs) are the most harmful form of air pollution, smaller than 0.1 micron. By sheer number, they make up over 90% of all airborne particles. Because they are so tiny, ultrafine particles can stay in the air for hours, are easily inhaled deep into our lungs, and get absorbed into the bloodstream. From there, ultrafine particles reach every organ and every cell in our body and disrupt their proper operation. Ultrafine particles have been linked to heart attacks, strokes, asthma, and even cancer. An independent study demonstrated that the IQAir CleanZone SL can remove 94% of ultrafine particles from the air.

Exceptional pollution control

Diesel soot, allergens, viruses, and all other airborne pollutants, including tiny but deadly ultrafine particles, are captured by the CleanZone SL. The CleanZone SL stand-alone air purifier was developed for offices, schools, hospitals, and other commercial sites negatively affected by elevated levels of air pollution. IQAir filtration media in the CleanZone SL removes more than 99% of all particles 0.3 microns or larger and is proven to filter ultrafine particles down to 0.003 microns in diameter, the smallest particles that exist. 

High airflow

The CleanZone SL has an exceptional airflow capacity of up to 820 m3/h minute (cfm) while meeting the most stringent noise standards and providing unequaled air filtration. The high capacity of the CleanZone SL enables it to provide up to four complete air changes per hour in a 200 cubic meter room. Air is drawn in from the bottom of the CleanZone SL system and is directed upward into the environment to avoid annoying drafts and discomfort.

Exceptionally quiet

At 45 dB(A), the CleanZone SL is the quietest high-performance air purifier in the world, virtually inaudible even in quiet indoor spaces, such as offices and classrooms. Even at the highest fan speed setting, the CleanZone SL only generates an incredibly low sound level of 45 dB(A). That is a three times lower sound level than that generated by typical professional air purifiers and practically inaudible even in a quiet workplace environment.

Powerful tool against allergens and microorganisms

The CleanZone SL is extremely effective in the removal of all types of allergens and microorganisms, as the CleanZone SL as it is capable of cleaning all the air in a 93 m2 space once every 15 minutes, pulling pollutants through the CleanZone SL’s 99% efficient HyperHEPA filter four times an hour. The result is a very high reduction in the concentration of allergens and microorganisms in room air.

Energy efficient

While the CleanZone SL is one of the most effective air cleaning systems ever designed, it requires less than half the power of much smaller consumer air purifiers. At 75 watts of electricity on its highest setting, the CleanZone SL uses about the same as a conventional light bulb. This is due to an ultra-efficient fan and a very large filter surface area, which allows air to pass with ease through the dense filter.

Preserves precious floor space

The CleanZone SL mounts vertically or horizontally, up high or down low, freeing up valuable floor space in busy offices, classrooms, and other spaces. Airflow from the CleanZone SL can be directed where it's needed, without creating drafts or air disturbances that detract from its unobtrusive operation.

Economical, low-maintenance operation

The CleanZone SL provides remarkable air-cleaning power for classrooms and other noise-sensitive environments, but costs very little to operate. It costs only a few cents a day to clean the air in environments up to 836 square meters. The powerful IQAir CleanZone SL fan is maintenance-free, so there’s no cost to keep your CleanZone fine-tuned.

Swiss quality

Swiss Made is more than just a label of origin. It’s a sign of outstanding quality, uniqueness, superior design, innovation, precision, and reliability. The CleanZone SL has not only been Swiss designed and engineered, it is also manufactured in Switzerland. Our devotion to the Swiss Made label exemplifies our commitment not only to what we make, but how we make it. By using the highest quality components, a team of dedicated craftsmen and women, and manufacturing processes refined over 50 years, IQAir is able to build the finest air purifiers in the world.
