Add Odor Control
    to Your Existing Business

    Hotel and OTA teams can begin with a room improvement pilot. Cleaning and property teams can add daily odor services, while chemical product and channel partners can start with ingredient samples.

    Hotels & OTAs: Improve Guestroom Odor Control Together

    Hotel and OTA teams review odor complaints and room-change records, while the hotel schedules room downtime. Guangwei handles assessment, treatment and room-by-room verification.
    Operators track recurring odors, guest feedback and room changes after the pilot, then extend the approach to comparable room types.

    Cleaning, Property & Pet Facilities: Add Odor Checks to Inspections

    Pilot one recurring odor point. Recheck apartments after handover cleaning, public restrooms after peak footfall, and pet facilities during boarding handovers.

    Record recurrence times, device condition and consumable use by shift to guide additional locations or maintenance changes.

    Fragrance & Product Development: From Odor Treatment to Samples

    For fragrance or air treatment projects, assess and treat existing odors before resuming the fragrance service.

    Linen laundries can sample textile finishing on matching batches of odor-affected fabric. Chemical manufacturers can validate formulations by target odor and dosage form, or discuss LANGKUI-branded products.

    Pilot Projects & Annual Maintenance

    The hotel provides representative room types and working windows. Guangwei develops a pilot based on odor sources, and both teams use inspection records to decide the next step.

    Site Assessment

    Inspect walls, windows, HVAC drainage, bathrooms and fabrics. Record engineering repairs separately from odor-retaining points ready for treatment.

    Pilot Room Treatment

    Treat representative rooms first. Record odor intensity under comparable conditions, with room-by-room records, photos and follow-up checklists.

    Rollout & Maintenance

    Expand in batches using pilot records. Maintenance covers cleaning handovers, recurrence-prone points, outcome checks and operational feedback.

    Start with One Site or Zone
    Choose a representative room type or zone. Record when and where odors recur, then treat the space or place prevention devices.
    Compare odors under the same conditions and keep location and maintenance records before extending to similar rooms or other sites.
