Delta MRSA Air Cleaner

Our Air Unit is a portable air cleaner giving healthcare institutions an effective new tool for use in infection control. Airborne bacteria such as MRSA and C.Diff can circulate for hours in wards, acute care units and communal rooms, recent studies have shown that contamination from MRSA can be reduced significantly by the use of portable air filtration.

The unit which operates quietly in the background of a room draws in contaminated air from the environment, the air particles are ionised and forced through two HEPA filters which have been coated with an anti-microbial layer of nanoparticles capturing  both inorganic particles and microbes.

Test results show almost total elimination of bacteria within 40 minutes and 100% elimination after 3 hours.

The unit also removes 100% of airborne particles such as pollen, dust and mould spores all of which can trigger asthma and upper respiratory irritation.
