How It Works
The Aaira + HEPA incorporates a 4-stage cleaning system to help clean the air. A fan
forces air through the unit from bottom to top.
STAGE 1: Pre-lter.
STAGE 2: H13 True HEPA Filter.
The true High Efciency Particulate Air (HEPA) lter captures up to 99.97% of particles
down to 0.3 microns in diameter.
STAGE 3: Activated Carbon Filter.
The activated carbon lter absorbs odors, gases, and volatile organic compounds (VOCs).
STAGE 4: HOCl Generator System.
Hypochlorous acid is generated inside the machine, and absorbed by the cold
evaporation lter. The liquid is evaporated as air passes through the cold evaporation
lter. This disperses the HOCl throughout the airspace in the room allowing it to destroy
a variety of bacteria and viruses.
Unpacking and Setup
1. Remove the unit from the box and check that all the items shown in the product
overview are included. Retain the packaging for storing the unit or in the event it
must be shipped back for service.
2. The unit is shipped with the H13 True HEPA lter sealed inside a package wrap.
Detach the bottom cover and remove the package wrap. Then remove the lter
out, replace it inside the device and replace the bottom cover.
3. The unit is also shipped with protective polyfoam above the HOCl generator
assembly. Detach the top cover and remove the protective polyfoam. Then replace
the top cover.
4. Locate the unit on a at, solid surface in proximity to the electrical outlet.
5. Connect the power cord to the unit, and route the power cord to the outlet, but
do not plug it in yet. Make sure that the power cord is out of the way and does not
pose a tripping hazard, and is out of reach of children and pets.
6. Plug in the unit.
