The starters

A mirror to 400S, Airmega 400 is a clear reflection to the highest range model that you can barely tell apart. From the “smart” exterior design that seamlessly blend in the air intake, the air purifier looks modern and futuristic even from a far point. 14.8 x 22.8 x 14.8 in dimension and 24.7 lb weight is not the bulkiness considering its 4 legs stand comes as standard. Usability wise despite the lack of Airmega app remote support, standard controls is well-placed with clear indicator on each buttons. Whats more there is a 3 preset timer mode that allows auto shut down without having to rely on app. Other spec sheet available in Airmega 400 including 4 stage filtration, aforementioned Smart mode, 2 separate pre-filter/ HEPA filter indicator that based on usage, built-in timer (1, 4, 8 hours), 30 days money back guaranteed and 5 years warranty.

Airflow, CADR and everything in between

Despite being the second range air purifier, Airmega 400 never skim on performance efficiency and coverage. Expect the exact identical airflow delivery rate and applicable area for large room size at a maximum of 1560 sq. ft. with 2 air charges and 780 sq. ft. with 4 air charges. The 4 fanspeed is diversify enough for the highly rated Smart mode which includes autonomous purifying plus Sleep mode that will use minimal fan speed when all lights are out.CADR is equally impressive that provides swift purifying against Dust, pollen and smoke. At an overall of 350 cfm, Airmega 400 out pace most competitors model as shown on the comparison table above.

What’s inside count

^ Airmega 400 filters/ lifespan/ price

As mentioned earlier, Airmega 400 utilize a 4-stage filtration setup that consist of dual Pre-filter, Green True HEPA filter and Activated Carbon filter. How this works is when airflow flowed through either side of the air intake, the Pre-filter would filter out as much particles as possible giving the Green True HEPA more freedom space. The freed Green HEPA filter would then capture micron size particles e.g. pollen, mold, germs and bacteria without being burden by dust and hair. On the other end Activated Carbon filter would concentrate solely on smoke/gases coming from cooking, VOCs and cigarette smoke preventing them from flowing back out. Do note that this would be the end of the line as there is no Ionizer or UV-light in the whole filtration process.

Keep it down

As we touch on the airflow performance above, Airmega 400 noise level is less compare with what the airflow would output although in normal circumstances you can barely tell the differences. At lowest speed its perfectly fine for night time use or simply set it to Auto/ Sleep mode for autonomous operation. Power consumption is up there as industry standard so not the most economical unit in town. If you plan to use Airmega 400 24x7 always leave it in cost-saving Smart mode (Auto/ Sleep/ Eco) and the air purifier would accurately determine what is the optimal speed needed.

At what cost

Airmega 400 its one of the 2 400 series range that is only differentiated by the availability of Wi-Fi support. Being the non Wi-Fi version, pricing is of course cheaper but do not expect the margin to be big. Expensive as it may be, the air purifier does have a slight advantage in the filter replacement section as it only require one change annually for the bundled Max2 filter set.
