Weight
44 lb (20 kg)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, the exterior has a slightly different color scheme than you could easily tell apart. At [adimension] dimension and [aweight] 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, build quality 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 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.

6Filters And Performance
Slightly different from HealthPro setup, the 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, 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.Noise And Energy Usage
