Breathe Easy with Professional Ventilation Cleaning Across the UK
Why Air Ventilation Cleaning Matters
Poorly maintained ventilation systems are a silent hazard. Dust, allergens, grease, mould spores and bacteria build up over time—damaging indoor air quality and increasing fire risks, especially in commercial settings. In regulated environments, like commercial kitchens and healthcare facilities, dirty vents are not just an inconvenience—they’re a legal liability.
At LEX HYGIENE, we provide professional air ventilation cleaning services across the UK to keep your systems clean, compliant, and efficient.
