In this IQAir HealthPro Plus vs GC MultiGas review, we will compare two of the most popular air purifiers by the Switzerland-based company known for its medical-grade devices.
In fact, the HealthPro series was chosen by the Hong Kong Hospital Authority to help reduce the spread of both SARS-CoV-1 & SARS-CoV-2 and can be found in hospitals and medical centres around the world. Meanwhile, the GC MultiGas is praised for its ability to remove chemicals, gases, and odours. But which one is the better choice for you?
This side-by-side comparison will help you find out.

Comparison: IQAir HealthPro Plus vs GC MultiGas – What are the Differences?
Coverage Area
IQAir recommends the HealthPro Plus for rooms of up to 85 m² (1125 ft²), slightly less than the 90 m² (1240 ft²) suggested for the GC MultiGas. While both models could be used in even larger rooms, the amount of air changes per hour (ACH) would decrease accordingly.

Air Delivery & Filters
The HealthPro Plus uses the PreMax Filter F8 (S) and the HyperHEPA Filter H12/H13 (L) to remove 99.95% of harmful pollution particles down to 0.003 microns in size. The GC MultiGas, on the other hand, achieves an efficiency of at least 95% for those ultrafine particles.
With most competitors only able to capture particles down to 0.3 microns, this means that IQAir devices are able to remove particles 100 times smaller than most purifiers. Additionally, both the HealthPro Plus and GC MultiGas can be used to eliminate chemicals and odours.
While the HealthPro Plus relies on the V5 Cell MultiGas Filter to eliminate volatile organic compounds (VOCs) and other harmful chemicals like formaldehyde, the GC MultiGas uses the even more efficient GC Filter Cartridge Set, which packs the chemical removal power of more than 100 gas masks, for this task.

Working Noise
Depending on the fan speed, both the HealthPro Plus and GC MultiGas operate at a noise level of just 22 decibels (dB) on the lower end and a maximum of 56 dB on the higher end. In total, there are six different speed settings to choose from.
Thanks to a timer function, it is possible to set operating hours in advance and have the purifier shut down at a specified time. Alternatively, you can also program a different fan speed for a certain time period, thus having the device switch to a quiet sleep mode during the night.

Sensors & Display
In both models, the control panel consists of a 4-key touchpad with a 16 character, 2-line LCD. The HealthPro Plus and GC MultiGas monitor the actual usage of each individual filter, allowing you to keep track of the remaining filter life by simply looking at the LEDs on the display.

Connectivity & Compatibility
Since neither the HealthPro Plus nor the GC MultiGas support Wi-Fi, they cannot be connected to your smartphone or voice assistant. Instead, you will have to settle on the included remote control to control your air purifier from across the room.

Conclusion: IQAir HealthPro Plus vs GC MultiGas – Which is the Better Air Purifier?
With both models, you get a medical-grade air purifier with an efficiency far above most devices on the market. IQAir’s HyperHEPA filtration technology, able to capture biological contaminants, bacteria, and viruses in their airborne state – including SARS-CoV-2, the virus that causes COVID-19 – can be found in both devices.
Therefore, the right pick depends on your personal needs. If you are looking for relief from your asthma and allergy symptoms or protection against dust, mould or pet dander, opt for the IQAir HealthPro Plus and its total system efficiency of 99.95% against harmful ultrafine pollution particles.
If, on the other hand, you are suffering from elevated sensitivities to household chemicals and aim to remove VOCs (the cause of odours), harmful chemicals like formaldehyde, or second-hand smoke from the air you breathe, the IQAir GC MultiGas is the right choice.
