Respirable particulate matter pollution remains a key challenge for India.

"The finest particles are the more respirable," he said.

Respirable and fine particulates will also be monitored, but less stringently.

If we delay, respirable air will fail us.

A second type of respirator protects users by providing clean, respirable air from another source.

Due to their size, UFPs are considered to be respirable particles.

Examples of these from occupational health include the inhalable, thoracic and respirable fractions.

Some are small enough to be worn clipped to clothing, and are used to separate respirable particles for later analysis.

However, if inhaled as a respirable dust, or otherwise ingested alpha particles are terribly damaging.

This can cause health problems since the operator ends up inhaling respirable dust, which is also redeposited into the area being cleaned.
