Question

To ask the Senior Deputy Speaker whether the air handling units in the House of Lords have had electrostatic precipitators installed for the purposes of air filtration, particularly for viruses and bacteria.

There are no electrostatic filters in the air handling units (AHUs) in the House of Lords areas of the parliamentary estate. There are electrostatic filters in two AHUs in other parts of the parliamentary estate. They were installed in 2014-16 to act as a general particulate arrest system and were not installed to deal with viruses and bacteria.
