The Revolutionary Approach to Hotel Smoking Rooms

The renowned company HONU, based in Minato, Tokyo, has achieved a significant milestone with its specialized deodorization service, "The Power of Catalysts". This innovative service, aimed at converting hotel and ryokan (Japanese inns) smoking rooms into non-smoking areas, has successfully treated over 6,000 rooms nationwide. This article explores this groundbreaking service and its critical impact on the hospitality industry.

Overview of The Power of Catalysts

"The Power of Catalysts" employs a unique combination of platinum colloid, silver colloid, and titanium oxide to neutralize and decompose the volatile organic compounds (VOCs) that accumulate from cigarette smoke in a chemical process. This professional deodorization service doesn't merely mask odors; it eliminates them altogether, ensuring a fresh environment for guests.

Positive Feedback from Facilities

The response from facilities that have utilized HONU's service has been overwhelmingly positive. A general manager expressed, "We have tried various companies in the past, but the odor has not returned this time. It's been over six months since the treatment, and we have received zero complaints about tobacco smells!" Meanwhile, a hotel facility manager highlighted the cost-effectiveness, stating, "Transitioning to non-smoking floors with this service cost only one-tenth of what traditional renovations would have cost. And we could continue operations without any disruption. Also, the VOC measurements provided give us great peace of mind."

The Efficiency of Smoke Room Conversion

Hotel and ryokan managers no longer have to rely on wallpaper replacements or extensive renovations to convert smoking areas into non-smoking ones. HONU's service facilitates this transformation without considerably affecting the facility's operations or incurring high costs.

Post-treatment VOC measurements have shown an impressive 83% reduction in odors, with the effects proven to last over six months after the process. Notably, unlike methods that merely cover up the smell, this service ensures the elimination of tobacco odors without any chance of them resurfacing.

Indoor Air Quality Improvements

In another area of innovation, HONU addresses common challenges related to air conditioning systems in hotel rooms. Most hotels use concealed air conditioning systems, which are often difficult to maintain or clean. The company has developed a method to disassemble and clean these units effectively.

In a case study conducted in March 2026 in a city hotel in the Kanto region, treatment of 21 rooms resulted in a remarkable increase in airflow velocity from 0.50 m/s to a remarkable 2.00 m/s—an increase of four times. Cleansing and maintaining the air conditioning system leads to improved air quality and can significantly reduce utility expenses while also preventing the spread of unpleasant odors.

Three Key Reasons for Selection

1. Quick Turnaround and Cost Effectiveness

HONU can convert a smoking floor of approximately 800 square meters (around 33 rooms) to a non-smoking area in as little as five days. This process costs about one-tenth of that of conventional renovations. Moreover, rooms can be sold as accommodations just one day after treatment, minimizing operational losses.

2. Verifiable Results

HONU provides detailed reports before and after the treatment that include measurements of VOC concentrations and airflow tests, thus offering written evidence of their effectiveness. This scientific backing allows hotel managers to be confident in the service's impact.

3. Safety and Eco-Friendliness

All catalyst components used in the service are proven to have no adverse effects on human health. Since they do not contain fragrances, the service also addresses concerns about synthetic odors. As further testament to their safety, the service has been successfully implemented in healthcare facilities and childcare centers.

Extensive Implementation

HONU's deodorization services have been embraced by various major hotel chains and have already reached over 6,000 treated rooms across Japan, signifying a growing trend towards healthier indoor environments in hospitality.

Service Plans Offered

HONU provides two comprehensive service packages:

Plan A: Smoking Room Conversion Package

This plan includes catalyst coating treatment for the entire smoking area, covering walls, ceilings, floors, and air conditioning units.

Plan B: Guest Room Refreshment Cleaning

This full maintenance plan involves surface cleaning throughout the guest room, disassembling and cleaning concealed air conditioning units, and removing water stains, particularly effective in hot spring resorts and regions like Kyushu and Okinawa, known for hard water issues.
