IQAir air purifiers are equipped with an electronic Filter Life Monitor that calculates the remaining life of the system’s filter elements. Thanks to the filter life monitor, the user does not have to guess when filters need to be replaced orreplace them at fixed intervals (which rarely correspond to the actual amount of use). The Filter Life Monitor watches over the most important factors that affect the life of the individual filter elements. The Filter Life Monitor display shows the remaining life of each individual filter elements at any given time.

IQAir and AllergyBuyersClub recommend running your IQAir HealthPro air purifier for 10 hours a day on speed setting 3. Thanks to its superior performance and filtration, it does not need to be run 24 hours, 7 days a week. The average filter life for 10 hours of use per day on speed setting 3 is outlined below.
    PreMax Pre-Filter: 18 months
    V5-Cell Gas & Odor Filter: 2 years
    HyperHEPA Filter: 4 years

IQAir air purifiers can be set to run at six different fan speeds which correspond to six different air flow rates. The higher the fan speed, the more room air will be filtered by thesystem. The high fan speed settings provide additional air cleaning power to deal with situations of elevated pollution levels. To allow better evaluation of the system’s performance at different fan speeds, the standard display window shows fan speed and the air delivery rate (air flow).

For general air cleaning purposes, the IQAir system should be able to filter the room air volume at least twice every hour on the set fan speed to achieve a significant air quality improvement. If the intensity of the pollution source is high or a high degree of purification is needed, more air changes may become necessary.

Under normal conditions, IQAir and AllergyBuyersClub recommend running your IQAir HealthPro air purifier for 10 hours a day on speed setting 3 in a room around 500 sq. ft. with an 8 ft. ceiling. Thanks to its superior performance and filtration ability, it does not need to be ran 24 hours, 7 days a week to sufficiently clean the air in a room.

Using the daily & weekly programmable timer functions will help operate your IQAir air purifier at maximum efficiency, in accordance with your lifestyle. The programmable timer allows you to select a start time, end time and speed setting for the air purifier to operate at each day, Monday through Sunday.

The IQAir Klaus limited edition air purifier is the ultimate air purifier for people with health issues of a magnitude requiring absolute clean air. Although they are rather pricey, if you prefer to buy top quality and get what you pay for, you will not be disappointed.


  • Robust Pre-filter: a high-efficiency, high-capacity, tightly-pleated filter pack that holds back over 90% of all dust mass and prolongs the life and performance of the V5 cell filter and the hyper HEPA filter by a factor of 10
  • Superior hyper HEPA filter: has a micro particle retention rate up to 100 times higher than regular HEPA filters with a surface area larger than most of the air cleaners on the market
  • High performance V5 filter: a V-shaped compact filter reduces the gaseous contaminants both by physical adsorption and chemical breakdown while a maximum level of airflow is maintained (available with the Healthpro Plus. Healthpro can be upgrade to a Plus with the addition of this filter)
  • Maximum room coverage of up to 1,238 sq. ft. for the Healthpro and 1,125 sq. ft. for the Healthpro Plus when running on the highest speed. When run on medium speeds, they will cover a room up to 600 sq. ft.
  • Good for bedroom use with lower-than-average noise level on the first two fan speeds, on the third speed it is a pleasant quiet background hum. Speed 4 is a bit noisy, but some users will tolerate it, and like all HEPA air purifiers, it is fairly noisy on speed 5 and 6. These high speeds are best suited for quick cleaning of a room or for use when you are not at home.
  • Filter life and replacement costs: the IQAir's design allows filters to be replaced individually and on different schedules, which off-set the cost of having to replace all 3 at the same time. Average annual filter replacement costs are approximately $128.17 for the Healthpro and $202.34 for the Healthpro Plus. (Dollar values bases on 10 hour daily usage on speed setting 3.)
  • Advanced controls and remote: one of the big pluses of the IQAIR Healthpro and the Healthpro Plus is its control options. While we did not see the need for the remote control, we were impressed with the ability to set the machine to go on and off at certain pre-designated times and fan speeds. The four key touch pad displays the programming timer status, filter life and status, and fan speed.
  • Easy-to-change filters: all the filters stack up modular fashion and can be changed with no tools necessary—a huge plus
  • Constructed of non-off gassing: ABS materials that are UV stabilized and high-impact resistant
  • 3-D Ultra-seal design: a three-dimensional seal between the filter element and the housing of the air cleaner that does not allow any air to by-pass the filters so all the air is cleaned
  • Filter change indicator light provided for each of the 3 filters—it displays green until 20% of the filter life remains, orange when 20% remains, red when 10% remains, and flashing red when none remains, which is when you should replace it, although you should order your replacement when it indicates orange or red.
  • Has been in business since the 1960’s: selling air purifying products in hospitals and industrial clean-rooms
  • Certified performance: each IQAir air purifier is measured at the factory and certified by the quality-control engineer who tested it. Included in each box is a certificate of performance in air delivery, filter leakage and particle filtration efficiency.
  • IQAir will cover the Healthpro for a full 5 years: against defect in parts and labor since they consist of the highest-quality components and are assembled in Switzerland with great care, pride, and attention to detail.
  • Quality of filters: IQAir designs and manufactures all of their filters so you can be assured of the quality which includes the completion of the tight seal to the housing to eliminate by-passing to attain 100% filtration
  • Value for the price: although the IQAir air purifiers cost more than many air purifiers on the market, what IQAir provides in the way of quality, design and filtration performance strongly outweighs its higher price tag.


The IQAir Klaus limited edition air purifier is a designer representation of our number 1 choice for a room air purifier, the Healthpro Plus.
