FRAGRANCE FREE
Comfort without fragrance
We consider spaces where people with different scent preferences share the same environment. Usability that does not disturb the character of the space comes before adding fragrance.
BRAND MANIFESTO
Rather than masking odors with scent,
we focus on ways
that make spaces feel comfortable
Space odors are the result of how we live, ventilation, materials, humidity, and maintenance. Instead of covering the moment with strong fragrance, Zerosum aims for fragrance-free environmental care that puts less burden on the people who use the space.

ZEROSUM PRINCIPLES
Three standards
for how Zerosum views spaces
SPACE FIRST
A space-first approach
For residential, hospitality, healthcare, and commercial settings, we first assess the purpose of the space, usage frequency, and odor sources before defining scope of use.
DAILY CARE
Sustainable maintenance
We value building repeatable environmental care routines alongside ventilation, cleaning, and filter maintenance rather than one-time use.
Moments when
space discomfort begins
Environmental care is not only about spraying a product. Management becomes clearer when you look at where and when odors occur, ventilation conditions, and who uses the space.
01
After moving in/remodeling
After move-in or remodeling
We review ventilation and cleaning routines for new furniture, finishes, and spaces that have been closed for a long time.
02
Food and Pet Life
Food and pets
We manage recurring odor sources such as cooking, delivery food, and pet areas in daily life.
03
Multi-use
Multi-use and shift operations
In spaces where users change—hotel rooms, hospitals, stores—we prepare the environment before the next use.
04
Long-term storage
Long-term storage and enclosed areas
We manage areas where odors tend to linger—shoe closets, storage rooms, vehicles, and fabrics—according to how they are used.
OUR PROMISE
Quiet environmental care
that does not harm the impression of a space
We do not add one odor to cover another
We respect the atmosphere of the space and the preferences of its users.
We understand the use case first
We guide you based on space size, odor sources, and ventilation conditions.
We recommend it alongside basic maintenance
We also guide the fundamentals of indoor environments—ventilation, cleaning, and filter care.
