Energy Modeling of a Botanical Air Filter

According to the U.S. EPA Americans spend 90 percent of their time indoors where indoor air is two to five times more polluted than outdoor air. Toxins in the built environment have been found to cause adverse physical and mental health effects on occupants and are estimated to cost the U.S. 125 billion dollar annually in lost productivity. To address this challenge a novel botanical air filter...

Air Pollution Technology Fact Sheet: Paper/Nonwoven Filter- High Efficiency Particle Air (HEPA) Filter

3. Applicable Pollutants: Submicron Particulate Matter (PM) greater than or equal to 0.3 micrometer (μm) in aerodynamic diameter, and PM greater than or equal to 0.12 μm in aerodynamic diameter that is chemically, biologically, or radioactively toxic; hazardous air pollutants (HAPs) that are in particulate form, such as most metals (mercury is the notable exception, as a significant portion of ...

Automation of microbial enumeration: development of a disposable hydrophobic grid-membrane filter unit.

A disposable filter unit containing a hydrophobic grid-membrane filter (HGMF) was developed. The unit is liquid tight to serve as a specimen transport container and, by removal of the funnel extender (175- or 300-ml capacity), the unit becomes less than the height of two stacked petri plates to save space during in situ incubation. The polyethylene mesh which supports the HGMF facilitates rinse...
