No Zapping Sounds
The Oreck can make frequent, loud zapping
noises, as a result of the electronic plates it has inside. The
Multi-Tech air purifier does not produce any annoying or disruptive
noise, just the quiet sound of the fan.
Fan / Air Flow
Both air purifier models use a fan to
move the air. The Multi-Tech ionic air purifier uses two fans.
Ionizer
Both the Heaven Fresh "Multi-Tech"
and Oreck air purifiers feature an ionizer just inside the air
outlet, which circulates air-cleaning negative ions throughout the
room. Negative ions cause the precipitation of particles out of the
air, and are also able to destroy some airborne micro-organisms.

Air Filtration
Both air purifiers have a pre-filter
and an activated carbon filter. The Multi-Tech also features a
Hepa air filter, which is generally considered the most
effective type of filter for capturing particles and bacteria.
Cost
The Multi-Tech HEPA
& ionic air purifier is much more affordable, starting at $179. The Oreck Super Air 8 air purifier retails at $350. The XJ-3000C HEPA
& ionic air purifier does have the HEPA/activated carbon air
filter combination cartridge that needs to be replaced every one to
two years, but it costs just $32 per replacement. The ultraviolet
also needs to be replaced every 12-15 months, at just $15 per
replacement. However, the UV lamp is an added benefit, and is not
required for the other technologies of the Multi-Tech air purifier
to function at full strength. The Oreck air purifier also requires
replacement costs.
