IQAir currently has products that fall into four product categories:1. Portable room air purifiersFirst introduced in 1998, the modular design of its portable room air purifiers allowed IQAir to create different models with optimized air filtration technology for the removal of specific groups of air pollutants. One of IQAir’s most popular models is the HealthPro 250 , which uses three separate filter stages that are arranged in a modular tower design. In August 2012, the company announced a major overhaul of its portable room air purifiers with the designation "New Edition". The new air cleaners have improved airflow, filter life and reduced sound levels.2. Large commercial air cleaning systemsIn July 2013, IQAir introduced on its website two new commercial air cleaning systems: the CleanZone SL and CleanZone 5000. These two systems are intended for larger commercial spaces such as open plan offices, hospitals and classrooms. The CleanZone SL is a slim, wall-mounted air cleaning system for particularly noise-sensitive indoor environments. The CleanZone 5000 is a large, mobile air cleaning system that is available in various configurations to address specific groups of particulate and gaseous air pollutants.3. HVAC-based air cleaning systemsIn 2006, IQAir introduced its first air cleaning system to work in conjunction with ducted forced-air heating, ventilation and air conditioning (HVAC) systems. The Perfect 16 derives its name from being the first independently tested residential and commercial air cleaning system for HVAC systems to achieve the highest minimum efficiency reporting value (MERV 16) under the ASHRAE 52.2 test format.[15] Other characteristics of the system include very low pressure drop and a filter life of up to 3 years.4. Handheld laser particle countersIn 2000, IQAir introduced a line of hand-held optical particle counters.IQAir develops and manufactures all of its products at the IQAir Technology Center in Switzerland.IQAir’s portable air pu ...
