From one of our very happy 5-Star Hotel GM’s here in Singapore:
“As the general manager of a five-star hotel in the heart of Singapore, nothing keeps me awake at night quite like taking guest rooms out of inventory. Recently, I was honestly worried when I had to pull five rooms offline due to a persistent, mouldy odour. Guests noticed it immediately, and if there’s one thing I know in this industry, it’s that first impressions are everything.”
“We began with a thorough inspection of the affected rooms. To my surprise, there were no visible leaks, but we quickly discovered that the carpets in two of these rooms had absorbed quite a bit of moisture over time. Recognising the urgency of the situation, I reached out to ProMedUSA, knowing they had just the right solutions for us.”
“For our first step, we turned to “Tersano Stabilized Aqueous Ozonated Water (SAO)”. This impressive technology generates ozonated water on-site using just water and electricity, allowing for powerful cleaning and sanitising without harsh chemicals. Knowing that SAO is effective against a wide array of bacteria and viruses gave me the confidence we needed to tackle the issue head-on.
Using our carpet cleaning extractor, we injected the ozonated water directly into the carpets and then extracted it. This method penetrated deeply into the backing of the carpet, effectively killing the source of mould and the unpleasant odour. We repeated the process twice to ensure that no trace of the issue remained.”
“Next, while the carpets dried, we brought in the “AirPro-Max Bipolar Ionizer”. This fantastic unit was perfect for targeting any lingering mould spores in the air. The AirPro-Max uses advanced bipolar ionization technology to purify the atmosphere. Not only does it kill the remaining mould spores floating in the air on contact, but it also reduces airborne particles like dust and allergens, all while tackling those pesky persistent odours.
What I love about this system is that it works throughout the entire space. Unlike traditional filtration methods, the AirPro-Max disperses bipolar oxygen ions across every corner, ensuring we create an all-encompassing fresh atmosphere. The result? A cleaner, more inviting indoor environment for our valued guests and no more mouldy smell.”
“Within just two days of implementing this two-step process, those five rooms were back in service—odour-free and ready for guests. This swift turnaround not only boosted our revenue but also reinforced the critical importance of effective indoor air quality management in maintaining our hotel’s reputation. The return on investment was considerably less than what we would lose in just a few nights’ rental receipts— definitely Value-for-Money!”
“This experience changed how we approach housekeeping and maintenance. We now evaluate not just visible wear and tear but also potential sources of odour and the air quality implications of every product we introduce. In hospitality, cleanliness isn’t just what you can see; it’s also about what guests smell the moment they walk through the door.”
“Partnering with ProMedUSA has been a pivotal decision for us. Their mission aligns perfectly with our commitment to creating healthier and safer environments without relying on complex, harsh chemicals.
The combination of “Tersano’s SAO” and “ProMedUSA’s AirPro-Max” has completely revamped our indoor air quality strategy. By integrating these technologies into our operations, we’ve significantly reduced our reliance on chemical products, lowered our operational costs, and adhered to our sustainability goals. We value partners who understand the standards our guests expect and who help us consistently deliver a clean, comfortable, and welcoming stay.
For any hotel or facility in Singapore aiming to enhance cleanliness and air quality and improve their bottom line, I can honestly say that the combination of Tersano SAO and the AirPro-Max is a game-changer.
At ProMedUSA, you’ll find a dedicated partner ready to enhance the hospitality experience. They’ll work side by side with your staff to create spaces that are not only clean but also inviting and safe for everyone.”
