As air flows in from both left and right, Airmega 300 2 pre-filter would cover each side of the air intake stopping any large particles such as hair from proceeding. With smaller particles sneaking pass the pre-filter, the always reliable Green True HEPA filter would trap micron size particles including bacteria and viruses at a 99.97% rate.

All that missing from the filtration list is an optional ionizer that is available in most air purifier in this category.
