1. An air purifier comprising:
an ambient air intake configured to draw ambient air into the air purifier;
a plasma reactor configured to generate one or more reaction products from the ambient air;
a main body comprising at least the plasma reactor;
a neutralizing trap configured to neutralize at least a portion of the one or more reaction products generated by the plasma reactor, thereby producing a purified gas stream; and
a purified gas outlet configured to expel the purified gas stream from the air purifier;
wherein:
the ambient air intake is fluidly coupled to the plasma reactor;
the plasma reactor is fluidly coupled to the neutralizing trap;
the plasma reactor is centrally located in the main body;
the neutralizing trap is fluidly coupled to the purified gas outlet;
the neutralizing trap is disposed radially outboard of the plasma reactor;
the neutralizing trap surrounds the plasma reactor;
the neutralizing trap comprises a plurality of neutralizing trap blocks, each neutralizing trap block having an inlet end and an opposite outlet end;
a neutralizer inlet area is defined in the main body;
the plurality of neutralizing trap blocks includes a pair of neutralizing trap blocks, the pair of neutralizing trap blocks being disposed with the respective inlet ends adjacent the neutralizer inlet area, a gas flow path being defined from the plasma reactor to the inlet area, the gas flow path splitting to flow through each of the neutralizing trap blocks in the pair; and
neutralizer outlet areas are defined in the main body, each neutralizer outlet area being adjacent the outlet ends of one of the neutralizing trap blocks in the pair.
