1.Do the IQAir Air Purifiers produce ozone?

No. Ozone is a powerful lung irritant that is produced by other air purifiers and ozone generators but not in the IQAir air purifiers. IQAir purifiers do not generate any ozone so you can enjoy fresh, ozone-free air every time you use your air cleaner. All units are certified with the IAACM (International Association of Air Cleaner Manufacturers) and are approved by the California Air Resource Board (CARB), which maintains stricter air quality and ozone emissions standards for home appliances in California than even the U.S. Environmental Protection Agency.

2.How quiet is an IQAir Air Purifier?

IQ air purifiers, like the IQAir HealthPro Plus, are extremely quiet because of their ultra modern design. IQAir air purifiers feature unique double-walled housing to reduce sound transmission and eight shock absorbers to reduce vibration. IQAir follows the ISO 3744 standard for measuring the decibels. Each unit has a variable fan with 6 speed settings, and with a redesigned New Edition fan, IQAir purifiers are quieter than ever. Below lists the decibel levels for each speed that apply to nearly all IQAir air cleaners:

Speed 1 – 25
Speed 2 – 36
Speed 3 – 44
Speed 4 – 50
Speed 5 – 54
Speed 6 – 59

3.How much energy do the IQAir Air Purifiers use?

Even though they are powerful machines, each model is extremely energy efficient. IQ Air air purifiers achieve outstanding energy efficiency by including a very efficient fan and an advanced fan control set-up in every unit. As a result, it costs only pennies a day to run them. Typically power consumption for each model ranges from 27W on low to 215W on the highest setting.

4.What is the difference between a standard HEPA filter and the IQ HyperHEPA filter?

All HEPA filters are tested, measured and held to the standard filtration rate of 99.97% of all particles 0.3 microns and larger. This is the U.S. HEPA standard, but in the EU, there are actually different levels of HEPA that use particles 0.22 or smaller as the baseline size. The majority of ultrafine particles are actually even smaller than 0.3 microns, so the HyperHEPA filters have been designed to filter particles as small as 0.003 microns and can remove 100 times more allergens than regular air cleaners. For specific filtration rates of each type of HEPA filter IQ uses in each of its air purifiers, please refer to the specifications chart on each product page.

5.What particles do the IQAir Air Purifiers remove?

Each IQAir air purifier filters out harmful airborne allergens like mold spores, pollen, animal dander, dust, and tobacco smoke from your indoor air. Additionally, you can upgrade many of the IQAir air purifier models to include protection against gaseous chemicals, fumes, odors, and Volatile Organic Compounds (VOCs), with additional filters. So regardless of your filtration needs, there is an IQAir to meet them.

6.How many filters do the IQAir HealthPro series air purifiers use?

Both the IQAir HealthPro and the HealthPro Compact include a HyperHEPA filter which absorbs 99.97% of airborne particles as small as 0.3 microns and a PreMax Pre-Filter which can remove over half of all particles 0.3 microns or larger, before they even reach the HEPA filter. The IQAir HealthPro also has an optional V5 filter, which uses 5 lbs. of blended activated carbon for gaseous chemical and odor control. The IQAir HealthPro Plus comes standard with the IQAir patented HyperHEPA filtration, PreMax pre-filter, and a V-5 Cell Gas and Odor filter.

7.How many filters does the IQAir GC or GCX air purifier use?

IQAir offers several GC and GCX air purifiers to choose from, including the IQAir GC VOC, IQAir GC Multi-Gas, IQAir GC Chemisorber, and IQAir GC AM. For each, they also offer GCX versions of these air purifiers, which have even larger filter cartridges and are best suited for larger, commercial spaces that require specialized gas, odor, vapor and smoke control. Each IQAir GC Series air purifier focuses on specific filtration needs and contains three stages of air filtration. The IQAir MultiGas GC Series air purifiers include one HEPA-type pre-filter, four specialized gas cartridges and four post-filter sleeves to effectively capture a broad range of airborne pollutants.

8.How do I know when to change the filters?

Each unit comes equipped with a digital monitor that lets you know when it is time to replace the filters. The topside control panel has lights labeled F1, F2, and F3. Green light indicates the filters are good. Once the light turns orange, this is an indication that the filter is down to 20% of its effective life. A red light indicates it is time to replace the filter, NOW. Specific replacement times for each individual filter varies, but generally prefilters will have to be changed first, then carbon filter or cartridges and lastly, HEPA filters.

If you’re not using your IQAir air purifier, there are a couple things to keep in mind. While not in use, HEPA and prefilters will pick up right where they left, meaning unless you’re actually using the machine, the filters are basically in holding pattern. This isn’t so with carbon filters. Even if you’re not using your machine, activated carbon will continue to pull in pollutants from the air around it. So over time, these filters will very slowly continue to adsorb pollutants, and when you begin actively using your machine again, the filter life will not be as long as listed on the control panel. If you know you won’t be using your machine for a longer period of time, you can keep carbon filters “fresher” by sealing them away in a plastic bag. This can eliminate any air flowing through them and dramatically decrease or even stop the adsorption process.

9.How do I change the filters in the IQAir Air Purifiers?

Changing the filters for any IQAir unit is simple. Every IQAir purifier features a revolutionary modular tower design which snaps open to allow easy access to all filters in a matter of seconds. Disconnect the system from the power supply before opening the unit. Then simply un-snap the arms of the unit, and remove the segment holding the filter(s) you want to replace. Pull out the dirty filter, replace with a clean one, and snap back into place. Replacing a filter has never been easier!

10.How many filters are included in the IQAir Commercial grade air purifiers?

IQAir features a few commercial grade air purifiers, including the GCX models as well as the IQAir Dental Pro and the IQAir Cleanroom H13. The IQAir Cleanroom H13 includes a 75 sq. ft. mini-pleat fine dust pre-filter and a 81 sq. ft. HyperHEPA filter. The IQAir Dental Series air purifiers contain one HEPA-style pre-filter, two Mercury Cartridges, two Multi Gas Cartridges, and four post-filter sleeves.

11.What is the difference between an IQAir GC and GCX air purifier?

Both models are nearly identical, but the main differences between comparable GC and GCX models are the amount of filter media and size. GCX units, overall, contain more filter media than comparable GC models and are best used in commercial or industrial filtration settings. This means a few things. First, GCX models can run longer on the same set of filters, so replacement is less frequent. GCX models also have a slightly higher CFM since they have to push the air through more filter material and overall, are taller (to accommodate larger filter canisters). With this larger size comes a slightly higher price, but aside from one model being larger than the other, they are very similar machines in terms of performance.

12.Are IQAir HEPA Air Purifiers effective for individuals with Multiple Chemical Sensitivity?

Absolutely! The IQAir MultiGas GC air purifier offers excellent, well-rounded protection for individuals suffering from Multiple Chemical Sensitivity. Specialized carbon, a HEPA pre-filter, and electrostatically charged post-filter sleeves trap the widest range of particles while oxidizing more chemical pollutants than nearly any other air purifier available. This is why we’ve rated the IQAir GC MultiGas as Best in Class for MCS.

13.Does my air purifier come with casters?

This has changed from the past, so now ALL IQAir air purifiers come with casters that can be installed when you receive the machine. The ONLY machine that now lacks casters is the H13 Clean Room air purifier.

14.What type of warranty comes with the IQAir Air Purifiers?

Depending on the model you choose, IQAir units are covered by a one, two, or five year warranty. IQAir warranties provide protection against defects in material or workmanship, but do not cover misuse or abuse of the unit nor filters. Please check with the respective office.

15.What sets IQ apart from other air purifier manufacturers?

The American Lung Association chose IQAir as their partner for indoor air quality. It doesn’t stop there; IQ Air was also chosen by Hong Kong Hospital Authority as the only air cleaner strong enough to fight against SARS. IQAir was the provider of air purifiers for athletes during the 2008 Beijing Games and also works with Extreme Makeover Home Edition in providing in home air purifiers for families who need quality air filtration. Additionally, you can find IQAir air purifiers in homes, businesses, and government installations around the world.

IQAir Company Information and History

“My father and his brother started our family company in Germany. They introduced the world’s first home air cleaner in 1963. The history of room air cleaning begins with IQAir,” says Frank Hammes, son of Klaus Hammes and President of IQAir North America.

As the developer of the first residential air purifier, IQAir continues to impress consumers. IQAir has the experience, resources, and commitment to produce air cleaners of the highest caliber. With over 40 years of experience in the air purifier industry, IQAir has demonstrated that they take air cleaning to the highest level, often surpassing consumer expectations.

As a child in Germany, Manfred Hammes suffered from chronic asthma and allergies, leading him to join with his brother Klaus to create a simple yet effective air filter system. With the use of a filter pad with small magnets attached to an air outlet of residential coal ovens, the Hammes brothers filtered dust from heated air, thus creating the first air filter for household use.

After 1963, the company went through many changes, including incorporation under the name of Incen AG, still an industry leader throughout Europe. In 1991, Frank Hammes established National Environmental Control, Inc in Pasadena, CA. There, National Environmental Control joined with Mercedes-Benz to distribute cabin air filters as add-on accessories for the Mercedes-Benz luxury automobile line. The aftermarket product became so popular that Mercedes-Benz and Volvo began manufacturing the filters created by National Environmental Control.

After four years of research, the first advanced IQAir air purifier was introduced to the European marketplace in 1998. IQAir quickly gained a reputation for world-class performance and Swiss precision. Rated “Best Air Cleaner” in 1998 by Europe’s leading product testing organization, Stiftung Warentest, the IQAir filtration units represent the best in modern technology.

“For over 40 years we’ve maintained the commitment to build the very best air cleaning systems in the world. With IQAir, we have created the most advanced room air cleaners available today,” says IQAir President Frank Hammes.

Due to the success of the first advanced IQAir air cleaner, IQAir introduced a revolutionary, modular air filter housing design to the United States in 2000. The IQAir air purifier instantly became the best selling high-end room air purifier. Two years later, IQAir became the first and only room air purifier to incorporate H13 class certified HEPA filters. H13 HEPA certification verifies that IQAir air purifiers capture up to 100 times more particles than any other conventional HEPA air purifier.

The IQAir HealthPro exceeds the HEPA standard. The IQAir HealthPro air purifier is the only air cleaner to pass the world’s most advanced and stringent HEPA filter test, the EN 1822. This test certifies a filter’s absolute minimum efficiency for all sizes of particles. Traditionally, the HEPA filter’s efficiency had been measured at 0.3 microns, but over 90% of airborne pollutants found in homes and offices are smaller.

However, based on technology that IQAir developed for hospitals and multi-million-dollar clean rooms, the IQAir HyperHEPA filter has been EN 1822 tested and certified to filter down to 0.003 microns with a guaranteed minimum efficiency of over 99.5%. The IQAir HyperHEPA filter is now incorporated into every IQAir HealthPro series air purifier to ensure that every household has the best home air cleaning system.

In October of 2003, the Hong Kong Hospital Authority (HKHA) selected IQAir’s advanced air filtration systems as control measures to fight the SARS virus. After weeks of intensive testing by the Electrical and Mechanical Services Department (EMSD) of the HKHA using a sophisticated laser particle counter on the HVAC system and room air cleaners, the EMSD determined that IQAir air filtration system was the only system that could remove the tiniest airborne particles, including the SARS virus, from the air. IQAir’s four-stage filtration process reduces the risk of contamination and spread of the infectious SARS virus.

“This is true prevention,” says Frank Hammes, “Hong Kong is breaking new ground in infection control.” In addition to Hong Kong, IQAir advanced air systems are used by hospitals and critical environments worldwide.

The IQAir HealthPro series is specifically designed to remove solid and liquid airborne particles and aerosols including mold spores, pet dander, dust mite, pollen, bacteria, and infectious microorganisms. With the use of IQ Air’s patented HyperHEPA filter and super efficient pre-filter, the IQAir HealthPro air purifier is the most efficient and effective air purifier on the market today.

In 2004, the IQAir HealthPro Plus air purifier and the IQAir GC Multigas air purifier were selected by Reviewboard Magazine to receive the Editor’s Choice Award for Best Air Filtration System: “So if you are looking for the best air filtration systems for your home then the folks at IQAir have what you are looking for. The IQAir Health Pro Plus will filter your air, control the mold, pet dander, dust mites, pollen, lite tobacco and general air pollution.”

IQAir has committed their resources to raising awareness about indoor air quality issues by forming a partnership with the American Lung Association (ALA). “IQAir brings many outstanding elements to the relationship,” says John L. Kirkwood, President and CEO of the American Lung Association, “including a clear commitment to the importance of protecting the public from air pollution indoors, which can often be two or five times more concentrated than outdoor air.”

“We are honored to partner with the American Lung Association (ALA),” says Frank Hammes. “They are the world’s most reputable organization committed to lung health. We share a common vision of providing superior scientific information on creating healthier indoor environments.” The ALA’s partnership with IQAir will combine IQAir’s 45-year commitment to air cleaning quality with the ALA’s 100-year commitment to preventing lung disease and promoting a cleaner environment. This partnership demonstrates IQAir’s dedication to providing the public with accurate and useful information and effective air purification systems.

The IQAir advanced air purifier systems have also been featured on the popular reality television show Extreme Makeover: Home Edition for a young girl who recently had a lung transplant. The system was so effective that IQAir was asked to by the show’s design team to create a high performance air cleaning system for families with HIV, cancer, and other life threatening illnesses. “We have taken our decades of experience and expertise to develop the perfect home,” says Frank Hammes.

The unique design of the IQAir HealthPro air purifier prevents shortcutting, which reduces the effectives of most air purifiers when the air outlet and air intake are positioned too close to one another. Shortcutting allows the newly filtered air from the air purifier to be re-filtered, which wastes air cleaning capacity on already filtered air. With its air intake and air outlet at opposite ends, the IQAir HealthPro efficiently cleans the polluted air in the room.

With independent filter stages, the modular design of the IQAir HealthPro air purifier allows each filter type to be replaced individually, instead of using time and money to replace a whole cartridge when only one filter needs to be replaced. For example, while the HyperHEPA air filter will last between two to five years with normal usage, the pre-filters need to be changed more frequently-every six to eighteen months. The IQAir HealthPro air cleaner also offers an Intelligent Filter Life Monitor, which calculates the life of each filter based on actual usage and ensures a long life for each filter.

With more clean air and less noise than standard HEPA air purifiers, IQAir air purifiers are perfect for homes, offices, pharmaceutical laboratories, production and research areas, hospitals, and medical and dental offices. The IQAir fan motor sits in the center of the filters, which absorb the motor’s noise. With a unique, double-walled housing design, the IQAir air purifier has eight shock absorbers, which hold the fan to ensure that the vibration is not transmitted to the outside environment.

As a Consumers Digest Best Buy, featured in the December 2004 issue, Consumers Digest found the IQAir HealthPro Plus air purifier to be “ideal for allergy sufferers.” IQAir air cleaning systems aren’t just for people who have asthma or allergies, but for anyone who wants clean air for their families. “We are honored by this recognition,” says Frank Hammes. “With so many air purifiers to choose from-this award helps consumers who are looking for the very best air cleaning.”
