Rensair Air Purifiers

Three things: H14 HEPA filtration certified to EN1822 (capturing 99.995% of particles at 0.3 microns — the highest classification under the European HEPA standard), integrated UV-C germicidal technology that neutralises pathogens trapped on the filter, and continuous-duty design for occupied spaces. H14 under EN1822 is the filtration standard used in hospital operating theatres and pharmaceutical clean rooms. Most commercial air purifiers use H13 HEPA at best — H14 is ten times more efficient at the critical 0.3 micron particle size where viruses and fine biological aerosols sit. The UV-C stage adds an additional layer of pathogen control that standard HEPA-only units don't provide.

The Q01B is rated for rooms up to approximately 75m² at five air changes per hour — the recommended minimum for healthcare infection control environments. For smaller rooms, the unit achieves higher air change rates, which improves pathogen removal performance. For larger open spaces or rooms with high ceilings, multiple units positioned strategically deliver better air change rates than a single unit at maximum fan speed. Give us a call with your room dimensions and we can calculate the right number of units for your required air change rate.

Yes — aged care is one of the primary applications for the Q01B. Aged care residents are typically immunocompromised, and communal dining rooms, activity rooms, and shared living spaces present high infection transmission risk. The Q01B's EN1822-certified H14 HEPA filtration combined with UV-C treatment provides the highest available standard of airborne pathogen control in a quiet, portable unit suitable for continuous operation in occupied spaces. Running a Q01B continuously in high-risk communal areas is a practical, low-disruption infection control measure.

Rensair recommends annual replacement of both the H14 HEPA filter and the UV-C lamp for units running continuously. In higher-contamination environments or where the unit runs at higher fan speeds, more frequent replacement may be appropriate. The replacement set ($899) includes both components. Replacing both together ensures the UV-C lamp output remains within the germicidal specification — UV-C lamps degrade over time and reduced output directly impacts pathogen neutralisation performance. Using genuine Rensair parts maintains EN1822 H14 certification on the replacement filter.

No — the Rensair Q01B is ozone-free. The UV-C lamp operates at a germicidal wavelength that neutralises pathogens without producing ozone as a byproduct. This is an important specification for occupied spaces — ozone-generating air purifiers are not appropriate for continuous use in rooms with people present. The Q01B is specifically designed for continuous operation in occupied healthcare environments.

Standard commercial air purifiers typically use H13 HEPA filtration without UV-C treatment — adequate for general office air quality and allergen reduction, but not the correct specification for healthcare-grade pathogen control. The Q01B adds EN1822-certified H14 filtration (ten times more efficient than H13 at 0.3 microns) and UV-C germicidal treatment that standard units don't have. For environments where airborne pathogen control is a genuine requirement — healthcare, aged care, high-risk commercial spaces — the Q01B is the correct specification. For general commercial air quality improvement in standard offices, a standard H13 unit is adequate and significantly cheaper.
