The pollution mask that fits under your helmet
Light, fog-free, and trims to fit any face — the motorbike and scooter mask built for riders in hot, dusty cities like Bangkok, Delhi, Jakarta and the Gulf.
Filters from ~USD 1 each · Reusable for years · 30-day returns
F96 filter: 99.86% particle filtration efficiency at 0.1 micron, verified by Nelson Laboratories.
In a QMUL laboratory comparison (BTS 2017), Totobobo reduced black carbon exposure by 71% — the best of five masks tested.
91% of users rated it comfortable in a fit-tested study (Li et al., 2022, n=22).
Filter grades range from F92 to Pro99; figures above refer to the F96 grade. In the QMUL comparison (2017 BTS conference abstract) each mask was sealed to a test chamber, so it measures filtration only — real-world protection also depends on how well the mask seals on your face. That is exactly what Totobobo’s transparent, trim-to-fit design lets you check. See over a decade of independent research on filtration and fit.
Riders in their own words
Used by riders in Hanoi, Bangkok, Jakarta, Luanda, San Francisco, Melbourne and beyond.
“I have been using Totobobo masks for 4 years while living in Hanoi. The pollution on the roads is quite bad, but the mask works great to cut down my exposure riding my motorbike around the city and on longer trips. I have a big nose which can be tricky for fit with any mask, but I don’t have to worry about that with the SuperCool design. I’m an environmental consultant — I researched many masks, and still feel Totobobo is the best I can get.”
— Doug Snyder, environmental consultant, Hanoi · read his full letter
“I ride motorcycles and spend hours behind exhaust pipes every day. The Respro won’t fit under a full-face helmet because of the huge velcro straps — and it’s ridiculously expensive.”
— Cameron, daily rider, San Francisco / Oakland
“My 5-year-old daughter is on our motorbike with us all the time. Your mask was the only one I could find that would fit a child — and she feels very comfortable wearing it. I’ve just ordered a second mask for myself.”
— Kelly Sheriff, parent, Indonesia
“I chose it over Respro for the customizable seal and comfort. The covered-nose design is what I need for cold morning rides — it stops my visor fogging.”
— Peter, Melbourne, Australia
“It fits under my helmet without fogging the visor. I just tweaked it with hot water to match my face.”
— Gergely, motorbiker

Which Totobobo fits under your helmet?
The question most mask brands don’t answer. Both versions use the same Nelson Labs-tested filters.
Full-face helmet (with jaw protection)
Use the mouth-only version
Low-profile, covers nose and mouth, and sits flush against the face without pressing on your visor or creating pressure points.
Open-face / half helmet
Use the standard mask
About 20 grams, so it adds no bulk and doesn’t interfere with helmet straps.
Why it works for riders
Fits under helmets
A thin profile and trim-to-fit body sit flat under a full-face helmet, with a mouth-only option for tight visors.
Clear visor and glasses
The 3D shell vents breath away from the eyes, so the fog-free design keeps your visor and glasses clear in stop-and-go traffic.
Easy breathing in heat
Minimal coverage and a fast-drying surface, with low breathing resistance for long idles and slow crawls in tropical humidity.
Reusable, not disposable
Replace only the filters (from ~USD 1), not the mask — far cheaper than disposables for daily riders.
Cost for daily riders
Reusable mask, cheap filters. The long-term math favours daily commuters.
| Mask | Price | Filter replacement | Long-term cost |
|---|---|---|---|
| Vogmask | USD 44 (3 months) | Fixed filter | High |
| RZ Mask | USD 40 (1 year) | USD 5 | Medium |
| Respro Sportsta | USD 55 (1 year) | USD 20 | High |
| Totobobo | USD 45 (2 years) | ~USD 1 | Very low |

Filtration you can verify
Unlike most mask marketing, the performance is independently checked.
Nelson Labs (USA)
99.86% filtration of 0.1-micron particles — smaller than PM2.5.
CUHK / Prince of Wales Hospital
Filtration comparable to fit-tested N95 respirators in testing published in the Journal of Hospital Infection.
QMUL laboratory comparison
Ranked #1 of five masks for filtration, with a 71% reduction in black carbon exposure (2017 BTS conference abstract; masks sealed to a test chamber, isolating filter performance).
Rider questions
Does it fit under a full-face helmet?
Yes. Use the mouth-only version — it’s low-profile and sits flush without pressing on the visor. For open-face or half helmets, the standard mask works well.
Will it fog my visor or glasses?
It’s designed to be fog-free. The 3D shell directs exhaled air away from the eyes. A clean seal around the nose, helped by trimming the mask to fit, matters most.
Does it filter exhaust gases like CO?
No — and we’d rather tell you straight. Particulate filters (including N95s) do not stop gases like CO or NO₂. Gas removal needs activated carbon, which works by adsorption: capacity depends on the mass of carbon, which is why industrial gas cartridges are bulky, heavy and carry rated service lives. A thin, lightweight mask can hold only a few grams, so a token carbon layer may saturate within a few rides — with no warning. Totobobo focuses on what a light mask can genuinely do well: filtering particulates (black carbon, PM2.5), the main measurable exposure for riders in traffic.
Is it comfortable in hot, humid weather?
Yes — minimal face coverage and a fast-drying surface, rather than the thick thermal fabric on masks built for cold climates.
How often do I replace the filter?
When filters look dirty or breathing feels harder. Daily riders in heavy pollution change them more often; filters cost around USD 1 each.
