    About the Company

    Built on Jianisi and Guangwei Environmental Technology, LANGKUI specializes in musty, recurring and damp odors in hotel rooms. We develop microbial odor protection solutions for commercial accommodation.

    Our group's nearly 30 years of mold-control and antimicrobial R&D are supported by an in-house microbiology laboratory and a GMP clean production facility. Patented slow-release odor control and long-lasting mold prevention technologies underpin our approach: trace the source, treat the problem and prevent recurrence.

    We focus on recurring guestroom odors, with practical treatment plans and clear follow-up records. Our work helps hotels reduce odor complaints and room-change losses while maintaining consistent room quality.

    How On-site Treatment Works

    Inspect Each Room

    Check wall bases, windows, air-conditioning drainage and fabrics. Record moisture sources, odor-retaining materials and affected rooms.

    Treat by Zone

    List leaks, drainage and cleaning tasks on the site checklist. Once these are addressed, schedule odor treatment around room availability.

    Verify Each Room

    Recheck rooms under comparable closed-door and air-conditioning conditions. Record odor intensity and room handover arrangements by room number.

    Source Odor Control Technology

    Assess moisture sources, airflow and odor-retaining materials. Apply treatment to specific points, with nano atomization for wider coverage.

    Room-by-room Records & Maintenance Checklists 

    Inspection checklists, treatment records and follow-up results help housekeeping plan room handovers, wet-season checks and ongoing maintenance.

    Daily Guestroom Prevention

    Prioritize low-floor rooms, external walls and rooms prone to dampness during the rainy season when placing nano slow-release devices.

    Ingredient Supply & Product Development

    We supply musty odor decomposition ingredients, with sampling based on your product use and formulation. Validated samples lead to trial orders and product development.

    Damp & Musty Basements
    Illustrative scenario | Mustiness keeps returning in low-floor hotel rooms. Pilot treatment in representative rooms, compare odors before and after, then track complaints, room changes and downtime.
