Airflow, CADR and everything in between
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.Airmega 400 is covered against
