The starters

With numerous awards and used in many TV series like Brother on Calls, is no surprise that IQAir GC MultiGas is rated number 1 air purifier for MCS, odors & smoke. Sharing the same timeless design as HealthPro Plus, IQAir GC MultiGas has a slightly different color scheme than you could easily tell apart. At 15 x 28 x 16 in (38.1 x 71.1 x 40.6 cm) dimension and 44 lb (20 kg) weight, it has the same size as HealthPro Plus and its a lot heavier due to the added filters. On to build quality, you will find plenty of rigid ABS plastic in this Swiss made air purifier. Fitted with 3D UltraSeal triple-seal technology, IQAir GC MultiGas is extremely solid with no off-gassing/ leakage but downside is the mobility which is not easy to say the least. Surrounding the air purifier you will find a 320 degree airflow output and top carrying handle. Control wise you have a standard IQAir digital screen that allows you to set the 6 speed, Intelligent Filter Life Monitor, advanced scheduling (programmable timer) where you can pre-set start time/ end time and speed setting from Monday to Sunday. Inside IQAir GC MultiGas you will find a 4-stage filtration with the main filters: HyperHEPA Pre-Filter H11 and GC MultiGas Cartridges. Other similar features you will find in all IQAir air purifier including certified airflow performance, IAACM (International Association of Air Cleaner Manufacturers) listed, no-ozone 100% Healthy technology and 10 years warranty.

Airflow, CADR and everything in between

With certified performance from IQAir, each unit of IQAir GC MultiGas is meticulously checked by quality control engineer on particle filtration efficiency, leakage and airflow performance. The strong 40 - 510 cfm airflow will pull all airborne irritants including dust from the bottom of the panel and release out clean air through the top panel. Controlling IQAir GC MultiGas abundant airflow is a 6 fan speed that allows precise adjustment. Sadly there is no Auto mode or sleep mode feature but you can achieve similar result via the advanced scheduler. All in all expect an impressive 1125 sq. ft. purifying coverage that cater for any room size, living room or lounge.

What’s inside count

^ IQAir GC MultiGas filters/ technologies/ lifespan

Slightly different from HealthPro setup, IQAir GC MultiGas 4-stage filtration is more oriented to chemicals filtration although that does not mean it will fall short in handling allergens and other microscopic particles. Let's start with the pre-filter, instead of a standalone pre-filter, IQAir GC MultiGas opt for the combination HyperHEPA Pre-Filter which save-space yet still very effective against allergens, smoke, bacteria and viruses as small as nano size. For stronger chemicals that is notoriously hard to capture, you have the Post-filter Sleeves that will eradicate activated carbon and chemisorption abrasion particles via its charged fiber structure. This is follow by GC MultiGas Cartridges that eliminate chemicals like formaldehyde through an oxidation process in its chemically active alumina pellet. As a final bonus point, IQAir GC MultiGas can actually reduce ozone level in your room rather then contributing more like an ozone generator.

Keep it down

Like HealthPro, IQAir GC MultiGas is filled with noise insulation galore from the curved fan design, sound deflector diffuser, thick double-walled housing and rubber suspension pad that reduces the motor vibration noise. As a result, this latest edition delivers 7% less noise than previous version at a mere 25 - 69 dB(A) noise. 27 - 215 W power consumption is acceptable despite the lack of Auto mode. The first 3 speed is in the lower tier consumption rate while the following 3 speed is of course in the higher tier group. For more optimize energy use, we recommend setting up the advanced scheduling timer to activate/ deactivate IQAir GC MultiGas when is needed.

At what cost

Undisputed build quality? Checked. Exceptional airflow performance? Checked. Outrageously expensive price? Checked. All above pretty much sums up IQAir GC MultiGas as an air purifier. However like IQAir HealthPro Plus, IQAir GC MultiGas prove to be the ultimate air purifier for long haul as filter replacement set is one of the most cost efficient in its category. Despite the expensive price for both HyperHEPA Pre-Filter H11 and GC MultiGas Cartridges, the filters has an amazing lifespan where you divide the day-to-day running cost is actually less than 1 dollar. Amazing stuff.
