ROAM Air Quality Monitor

Robust Optical Aerosol Monitor (ROAM Air Quality Monitor or ROAM) is the first locally-made air quality monitor developed by the University of the Philippines Diliman under the leadership of Dir. Len Herald V. Lim, Ph.D. This is possible through the help of the Department of Science and Technology - Philippine Council for Industry, Energy and Emerging Technology Research and Development (DOST-PCIEERD).

ROAM is a cheaper and better alternative to the foreign commercial air quality monitoring devices, and is suitable for the Philippine tropical environment. The monitor costs as little as 1/10th of commercial equivalents to acquire, and the capability of the project team to do local servicing cut costs for maintenance and calibration.

About ROAM

ROAM Air Quality Monitor (ROAM) is the first locally-made optical aerosol monitor capable of reading particulate matter concentration in air up to PM2.5.

Particulate matters (PM) in the air are respirable and could lead to different respiratory and cardiovascular diseases due to its composition. Rapid urbanization in developing countries such as the Philippines, has the highest chances of pollution concentration and PM which is the most common pollutant in the air has been dubbed to be a silent killer responsible for the death of millions of individuals every year.

ROAM is up to 93% comparable results when tested against certified optical aerosol monitors (both reference devices and DENR devices).

ROAM is a laboratory-grade sensor, which has the capability of real-time, continuous monitoring, and its results are scientifically validated.

ROAM is vying to mature to be commercially produced, as it is now in its last stages of development (2nd prototype). Currently, the Department of Science and Technology (DOST) has invested a total of PhP 20 million in both R&D and pre-commercialization projects for ROAM to succeed to have a better technology and investment readiness.
