traditional HEPA filter, the Halo is more complex, utilizing the same
Neutrodine filters found in GreenFumeHood products to give it the ability to capture a range of commonly used acids, bases and solvents.
The available fan module gives Halo the ability to move 135 to
220 cfm of air during several operating modes, which can be prepro-grammed. This amounts to two to four equivalent air change rates. The
unit monitors airflow and uses the light-emitting diode (LED) “halo” to
communicate its operating status. Leveraging the built-in electronics,
Erlab has designed a semiconductor-based sensor to allow Halo to detect
volatile organic compounds. Recognizing that Halo units would likely be
installed in large numbers, Erlab also designed a communications system
to allow users to sense any issues for occupants, and equipped the module with its e-Guard communication system. BacNet protocols relay
information through an Ethernet service, giving users the ability to
conduct routine maintenance or status checks via smartphone, tablet
Erlab isn’t the only company to offer a new take on overhead filtration. Air Science, Fort Myers, Fla., has also recently introduced its Purair
SKY ceiling-mounted filtration unit. Equipped with LED lighting and
a filtration chamber, the SKY utilizes much of the same filtration technology used by Air Science on its line of conventional ductless filtering
hoods and enclosure products. The Air Science Multiplex Filtration
System, as it’s called, has a pre-filter, main filter and optional safety filter
to create a customizable “sandwich” architecture that blocks contaminated air in a way that matches the type of application being used in the
environment. The filters, accessible through a clamping mechanism,
rely on an activated carbon particle formulation engineered for porosity
and surface area and can sense acids, bases and biological aerosols when
paired with HEPA or ULPA filters.
How these new systems will affect the long-term operational efficiency of a laboratory remains to be seen, although Erlab claims the
Halo system will be a low-maintenance device. Most laboratories, the
company says, may not need a replacement filter for two years or more.
Both have been just released and will require time to find adoption in

Ceiling-mounted laboratory filtration units from Air Science, called Purair
SKY, are equipped with an electrostatic pre-filter in addition to the Multi-
plex Filtration System.
