Accessible Safe Disinfection
The Mission
Design a more efficient, safest, eco-friendly and replenishable alternative to personal disinfecting.
Year
2020
The Impact
- Red Dot Design Concept Award finalist 2021.
My Role
I was managing the project progress and contributing to the research, sketching, prototyping, CAD, rendering, animation, and technical specification.
Team: Sangyu Xi, Lee Cusolito, and Xingyi jiang.
Problem statements
To slow the transmission of the coronavirus, people are actively taking actions, such as using soap and water or hand sanitizer while on the go to sterilize their hands.However, the media and research have unveiled the following problems of the existing hand sanitizers:
Overdose alcohol
A sanitizer containing 62% ethyl alcohol equals a 120-proof drink, which can be dangerous to kids.
Plastic pollution
Millions of sanitizer bottles are produced, adding to the billions of tons existing.
Inefficiency
Sweat and filth on your hands will dilute the alcohol and reduce its effectiveness significantly.
Awful experience
The alcohol smell, the stickiness, the dried skin after applied, the cliche packaging…
Water contamination
Tricolsan and triclocarbon from hand sanitizer pollute water bodies.
Aqueous ozone
Through research, we discovered that aqueous ozone, which is produced by the electrolysis method (below), will extract ozone, an effective hygiene gas, from water, and does not allow ozone to escape the water in a poisonous gas form until it has degraded into oxygen.
Value propositions
We conducted 3 rounds of user interviews with 11 people of different ages, gender, marital status, professionals, and income. Then we pinned out their pain points and ranked them into value propositions.

Customer discovery
Parents
Keeping her from putting fingers in her mouth after applying hand sanitizer is so challenging...the whole meal smells like alcohol.
Seniors
The cracking appeared...and then it began to bleed. Applying hand sanitizer was literally a pain for me.
Customer clerks
I know personally that my hands don't smell so good, but there really weren't any other options.
Aesthetic inspiration
White communicates hygiene and trustworthiness; translucency and round corners convey the softness; fluent and flat form factor benefits portability...finally the simple and honest design is where I'm going for.
The final design consists of 3 main parts: White body, replaceable resin cartridge, and water tank.
Capacity
The assemble strategy aWe experiment with an existing aqueous ozone mister that shares the same capacity of battery and water tank with mist. and find out that mist. can last at least 3 days when it has been fully charged and with maximum water.llows the user to screw off the screws and take off one side plate to do the repair.
How the technology works
To promote sustainability, mist. uses the authentic appearance of cardboard with minimal plant-based ink for the package, to reduce the environmental impact and ecological footprint.
The resin cartridge absorbs the calcium and magnesium ions to soften the water, in order to increase the longevity of the units.
When the filtered water enters the electrolysis unit, the electricity will split the oxygen ions from the water and combine 3 of them over the membrane to form ozone.

Packaging
To promote sustainability, mist. uses the authentic appearance of cardboard with minimal plant-based ink for the package, to reduce the environmental impact and ecological footprint.
