The MERV scale is designed to represent the worst-case performance of a filter when dealing with particles in the range of 0.3 to 10 micrometers. The MERV value is from 1 to 16. Higher MERV values correspond to a greater percentage of particles captured on each pass, with a MERV 16 filter capturing more than 95% of particles over the full range.
Air filtration standards differ between the U.S. and other countries. The American ASHRAE rating system does not account for changes in filtration efficiency due to electrostatic charge. These MERV ratings do not account for a decrease in efficiency over the first few weeks of use due to a drop in static charge.
MERV 14 filters are capable of reducing smoke particles by approximately 80% when operating at the filter's design velocity, so a CADR smoke rating on a simple filtering unit that uses a MERV 14 filter will be approximately 0.80 times the fan flow rate in CFM. If the filtering unit does not mix the test room's air very well, it may receive a ...
May says the best way to prevent microbial growth is to have a clean central air system and use a pleated media filter with a MERV (Minimum Efficiency Reporting Values) rating of 11. The rating ...
FFUs are typically manufactured in 4' x 2', 3' x 2', or 2' x 2' steel housings, which can be placed in ceiling grid bays of similar dimensions. [2] Units often contain a pre-filter as well as a HEPA (high-efficiency particulate air), ULPA (ultra-low particulate air) or other MERV (minimum efficiency reporting value) filter.
[citation needed] This refers to their Minimum Efficiency Reporting Value (MERV) rating. [citation needed] These ratings are used to rate the ability of an air cleaner filter to remove dust from the air as it passes through the filter. MERV is a standard used to measure the overall efficiency of a filter.
MPR is different from MERV, the Minimum Efficiency Reporting Value. The MERV system measures a filter's ability to capture large particles. The MPR only takes into account the microscopic particles between 0.3 and 1 μm.
Diagram of a HEPA (high-efficiency particulate air) filter. 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.
