3 sanitizing technologies in one device

The reason why G-Flash has combined three sanitizing technologies is because none of these technologies is prefect. But they can be work in a complementary way and make it better than ever.

Plasma Sanitizer

Just wear G-flash around your neck and switch on.  Unlike traditional ionizer, It releases both positive and negative ions to the surroundings. The ion plasma technology has been well used for commercial and domestic air purifier but they are usually non-portable desktop size. We have miniaturized it , make it portable and wearable.

UVC & Ozone Sterilizer

With 3 UVC LED we can increase the light coverage and eliminate any shadow zone, G-flash can effectively sterilize your personal belonging such as  face mask, phone, earbuds, earring, cosmetic brushes, cutlery or tableware etc.

Odor Remover

Removes odor with Ozone in enclosed space such as refrigerator, kitchen cabinet, and shoe cabinet and under the sink. Researches show with the present of Ozone, food in refrigerator can preserve for a longer period. 

Hygiene Hand

It allows you to avoid direct contact with public areas such as the doorbell, buttons in ATM, and elevator and minimize the chance of infection. Besides, we deliberately use pure copper in our design because is it well known that germs will disintegrate on copper surface.

Tests with 3M Petrifilm

G-Flash and G-Flash Mini had gone through rigorous bacteria tests using 3M™ petrifilm™  to make sure they work as expected.

Quattro Dynamics was founded in 2018 by 4 key members : Andrew, Ben, Ken and Gary. We have been working in product and application industry for more than ten years.  We concentrate In innovative projects like motor design, new cooling system, home appliance etc. Due to the Covid-19 last year, we are enthusiastic to build a powerful sanitizing gadget for our families. We quickly found there are many personal sanitizers on market that have exaggerated their ability for killing viruses.  Ionizer for example is designed to disperse dust particles is misleadingly told to have viruses killing abilities. We started to do bacteria test ourselves using  3M ‘s petrifilm and we investigated various technologies by studying how they are used correctly in terms of dose, time and distance,  and environment.  We also discussed a lot about their pros and cons. Eventually we come up with G-Flash and G-Flash Mini. We believe G-Flash can protect our love ones during the pandemic and after.  Thus,  we decide to offer it here in Kickstarter and share with you.

We have finished our design and we have just about to start mass production.  We hope that you will support us and to get more G-Flash to those in need. Thank you.
