Corsi–Rosenthal Box. An example of a homemade unit. The Corsi–Rosenthal Box, also known as a Comparetto Cube, [ 1] is a design for a do-it-yourself air purifier that can be built comparatively inexpensively. It consists of four [ 2] or five [ 3][ 4] HVAC particulate air filters that form a cube and a box fan to draw air through the filters.
HEPA filters are designed to arrest very fine particles effectively, but they do not filter out gasses and odor molecules. Circumstances requiring filtration of volatile organic compounds, chemical vapors, or cigarette, pet or flatulence odors call for the use of an activated carbon (charcoal) or other type of filter instead of or in addition to a HEPA filter.

Minimum Efficiency Reporting Value, commonly known as MERV, is a measurement scale designed in 1987 by the American Society of Heating, Refrigerating and Air-Conditioning Engineers ( ASHRAE) to report the effectiveness of air filters in more detail than other ratings.

3. SB. Baltimore’s powerful lineup should continue to thrive against a trio of nondescript Oakland starters, two of whom throw from the right side. Most of the team’s top hitters are widely ...
High-efficiency particulate air (HEPA) filter is at least 99.97% effective in removing particles ≥0.3 μm in diameter (as a reference, Aspergillus spores are 2.5–3.0 μm in diameter). High-level HEPA filtration and increasing air changes per hour (ACH) can reduce particulate matter (PM) and bacterial concentrations in the operating room.

A particulate air filter is a device composed of fibrous, or porous materials which removes particulates such as smoke, dust, pollen, mold, viruses and bacteria from the air. Filters containing an adsorbent or catalyst such as charcoal (carbon) may also remove odors and gaseous pollutants such as volatile organic compounds or ozone. [ 1]
