IQAir is a Swiss air quality technology company, specializing in protection against airborne pollutants, developing air quality monitoring and air cleaning products. IQAir also operates AirVisual, a real-time air quality information platform.[1][2][3]


IQAir was founded 1963 by brothers Manfred and Klaus Hammes, who introduced an air filter system for residential coal ovens in Germany to help reduce black dust build-up on the walls behind ovens. Manfred Hammes, a lifelong asthma sufferer, noticed that the filter reduced his flare-ups during the winter months. Klaus Hammes continued through the 1960s and ’70s to adapt the air filter for other heating systems such as radiators, baseboard heating and forced-air heating and cooling systems. In 1982, Klaus Hammes relocated the company headquarters to Switzerland.

In the early 1990s, Frank Hammes, Klaus' oldest son, joined the company and expanded research and development as well as in-house manufacturing. In the spring of 1998, IQAir shipped its first high-performance air purifier from its Swiss factory. In 2001, Klaus Hammes' second son, Jens Hammes, joined the business and helped expand IQAir to Asia and the Middle East.[4]


IQAir currently has products in four product categories, namely air purifiers[5], HVAC-based air cleaning, air quality instruments and the global air quality information platform AirVisual.


IQAir employs a wide range of particulate and gas-phase removal technologies in its air purifiers and air filters. The company has been a vocal opponent of ionizing and ozone-producing air cleaning technologies. IQAir’s air quality information platform uses artificial intelligence (AI) to calibrate and validate thousands of governmental and non-governmental air quality monitoring stations.

Company organization

IQAir is headquartered in Switzerland with major operations in Germany, the U.S., and China. Product development is based in Switzerland. Manufacturing is based in Switzerland and Germany. Field support and installation teams exist in Switzerland, the U.S. and China, in addition to authorized dealers support customers throughout the world.

Research studies

Hospital Infection Control

A 2006 peer reviewed study published in the Journal of Hospital Infection reported that an IQAir Cleanroom H13 air purifier reduced Methicillin-resistant Staphylococcus aureus (MRSA) contamination in hospital isolation rooms. The researchers concluded that "This portable HEPA-filtration unit can significantly reduce MRSA environmental contamination within patient isolation rooms, and this may prove to be a useful addition to existing MRSA infection control measures.[6]

A 2010 peer-reviewed study conducted at Singapore General Hospital and published in the American Journal of Infection Control in 2010 found that the use of IQAir portable air purifiers with HyperHEPA filtration reduced the spread of invasive aspergillosis (IA) by 50%. The researchers concluded that "The cost of widespread portable HEPA filtration in hospitals will be more than offset by the decreases in nosocomial infections in general and in IA in particular."[7]

Dental Aerosol Control

A 2010 peer-reviewed study in the British Dental Journal, found that the IQAir FlexVac extraoral air cleaning system significantly reduced potentially hazardous bioaerosols created during dental procedures.[8]

Classroom Air Pollution Control

A 2013 peer-reviewed US government study conducted by researchers from the South Coast Air Quality Management District (SCAQMD) published in the International Journal of Indoor Environment and Health found that IQAir stand-alone air purification and HVAC-based air purification was able to lower concentrations of ultrafine particles, fine particulate matter (PM2.5) and black carbon (BC) between 87% and 96%.[9]

In-Vehicle Air Pollution Control

A 2014 peer-reviewed passenger vehicle study funded by CARB (California Air Resources Board), conducted by researchers at the UCLA Fielding School of Public Health and published in Environmental Science & Technology found that an IQAir high-efficiency cabin air filtration was able to reduce ultra-fine particle exposure by 93% while keeping carbon dioxide concentrations in the range of 620-930 ppm.[10]

School Bus Air Pollution Control

A 2015 peer-reviewed study funded by CARB, conducted by researchers at the UCLA Fielding School of Public Health and published in Environmental Science & Technology, found that an IQAir school bus air purification system was able to reduce harmful air pollutants by 88 percent.[11]

In-home Air Pollution Control

A CARB-funded study by Lawrence Berkeley National Laboratory investigating reducing in-home exposure to air pollution found that IQAir MERV16 filtration on a supply system provided the greatest reductions in outdoor pollutant levels with indoor time-averaged concentrations that were lower than corresponding outdoor levels by 97– 98% for PM2.5, 97–99% for UFP, and at least 84–92% for BC and at least 97% for ozone.[12]

A two-year study conducted by UC Davis and funded by CARB focused on households with asthmatic children found that the use of high-efficiency filtration improves indoor air quality. Installation of IQAir stand-alone air cleaners and high-efficiency filters in central air conditioning systems were shown to improve indoor air quality across all particle size fractions, with the greatest improvement in the smaller size fractions. The study also found that while participants did not report reduced asthma symptoms, they did have fewer visits to doctor's offices and hospitals for asthma care and slept better if they also kept their bedroom door closed.[13]
