IQAir HealthPro Plus vs. IQAir GC Multigas Rating





Below we have included a table to clearly show you a few of the main differences between the IQAir HealthPro Plus vs. IQAir GC Multigas. We thought it would be easier to break the differences down by air pollutant category as each customer has a different need. As shown below, the main difference between these two purifiers is the IQAIR GC Multigas’ ability to absorb chemicals, gases, toxins, and odors.

The first thing that we love about the IQAir HealthPro is that the HEPA filters in this device filter particles much smaller than most air purifiers. Most HEPA air purifiers claim to capture ultra-fine particles of 0.3 microns in size, but IQAir’s HyperHEPA filters have proven to capture particles 100 times smaller than its competition.

Using a HyperHEPA advanced filter, these can capture particles down to 0.003 microns in size; 10 times smaller than a virus. What many people don’t know is these ultra-fine particles are actually the most harmful to your health. Ultra-fine particles make up 90% of the air pollution we breathe and easily make their way into your lung tissue and can travel to all vital organs in your body. So getting these out of the air in your home is of utmost importance!

The IQAir HealthPro will filter out the most common contaminants like pollen, mold spores, dust, bacteria, pet dander, and smoke, but it doesn’t stop there. It also filters out viruses and bacteria, which is important for those with compromised immune systems, asthma, and severe allergies. 

This model has a new and improved fan, which delivers up to 300 CFM and uses only 27 watts at its lowest speed, thereby cleaning your air while hardly making an impact on your electric bill. With its EvenFlow Diffuser, you get 320-degree clean air output which allows for better air circulation than air purifiers than simply push air out the top. 

This model comes with a remote control and an intuitive display panel. With a variety of programmable operating options, filter-life monitoring, and color-coded lights to indicate when the filter needs to be changed, you can fine-tune the device to fit your specific needs. The average filter life when run 10 hours per day is 18 months, which is 3 times longer than the average air filter. So while you may be paying more in upfront costs, you will save in the long run.

Trial Results

We tested the IQHealth Pro while in the midst of wildfire season and it quickly removed the smoke from our home, making it easier to breathe once again. It was so strong that we wondered if we put it in the driveway, would it clean the air around the entire house? After a day of use, with it sitting in the middle of our living room, the air in the entire house felt cleaner. No longer were were suffering from sore throat and itchy eyes and although this model is much more expensive than many other air purifiers on the market, we are confident in saying that if we had severe allergies, this would be the one we would go with.

The fan is very quiet on the low setting and gets progressively louder as you turn it up. This makes sense as you can clearly see that it is pulling in massive amounts of air, which make it great for when things get really bad. From the moment we took it out of the box it was clear that this Swiss-made device is well constructed and high-quality. Not light by any means, this is not really meant to be dragged around the house. Although the design leaves much to be desired, the end result is gives makes it easy to overlook its bulky aesthetic.

The IQAir CG Multigas looks identical to the HealthPro Plus aside from the lavender stripe running down the front, which we think improves its aesthetic. Other than that there is no way to tell them apart, other than what is going on inside the device. 

The IQAir GC Multigas air purifier is aptly named, as it is great for eliminating gases, odors, and chemical contaminants. Using the same HyperHEPA filter as the other model in our list, the GC also contains four disposable, gas-phase filter cartridges made with the highest quality activated carbon. Designed to reduce gases, chemicals and volatile organic compounds (VOC) that produce odor, these filters all work in tandem to clean your air. 

While the standard activated carbon filter uses lower-quality coconut-shell for absorption, the GC Multigas uses bituminous coal. This carbon is better at filtering the air as it is activated in a way that preserves the maximum number of micropores, which trap pollutants. Alumina pellets combined with ChemiSorber media are used to remove formaldehyde, and the way that each filter is positioned helps to improve air flow and system efficiency.

A surprising note to consider is that the GC MultiGas has the same chemical removal ability as 100 gas masks! 

While both machines on our list will give you cleaner air than the standard air purifier, this model takes it one step further. The price tag is not for the faint of heart, but if clean air is important to you and especially if you suffer from severe allergies or live in a highly-polluted area, the GC Multigas is a worthwhile investment.

Trial Results

Using the IQAir GC Multigas in our home gave us the same experience as the HealthPro Plus model; very clean air in a short amount of time. Nearly everything about the operation of these two models were similar, from the intuitive and easy-to-use remote control and display panel, to the sound of the fans. The only real difference was the peace of mind that came with knowing that the GC Multigas was taking air purification one step further and removing any toxic gasses and chemicals from the air as well.
