HSE guidance HSG258 covers workplace ventilation as part of employer duty-of-care. BREEAM and WELL both reward documented IAQ controls. The same kit covers all three plus delivers a measurable cut in staff absence.
HSE inspections increasingly cite ventilation as part of HSG258 enforcement, and BREEAM / WELL assessors need evidence at design and post-occupancy stages. Documentation expected:
Monitor everywhere, filter where the monitors flag a problem.
One monitor per ~30 desks (open-plan) plus every meeting room — CO₂, PM2.5, chemical VOCs and more, on a touch LED display. Lobby-friendly for employee visibility.
HEPA H13 + carbon + concealed UV-C where monitor data shows a recurrent PM2.5 issue (basement, urban-facing, lobby). 800 m³/h, low noise — desk-friendly.
Compact, quiet HEPA + UV-C unit for densely-used meeting rooms where CO₂ spikes hardest. 380 m³/h, low-noise — fine for video calls.
Includes 3× MEDI 8 (basement + 2× urban-facing zones) and 5× MEDI 4e (high-use meeting rooms). 8× air-quality monitors quoted alongside, in your currency. Free site survey and 12-month consumables.
Configure for my site →Same kit covers all three standards. Pack contains pre-populated templates for each.
At an average UK private-sector cost of £146 per sick day, a 20% absence reduction on a 120-person office recovers ~£27,300/year — well above the kit's lease cost.
Run my numbers →Five air-quality monitors in your office for 30 days, free. We'll send a heat-map of where CO₂ and PM2.5 hit the worst — then decide together where to filter.
