For the urgent cases of earloop replacement, we have a better and easier solution now – just cut the pair of earloop from a normal surgical mask and you can replace the broken strap as shown in the following photo:

I received an urgent call yesterday. My friend Kenneth is flying off today to China for a 3 weeks mountian climbing trip. His want to bring along his Totobobo mask but the O-ring holding the versatile strap to the mask has broken. He need a replacement strap urgently.

Broken O-ring of Totobobo strap

Happy Kenneth with his new replacement strap- ready to go!
It was lucky that I do have a couple of extra straps around and Kenneth is also living in the same town. He drove over to pick up the straps to replace his broken one.
I heard similar incidents of broken straps recently from India. Plus another new customer wanting to buy the earloop mask with additional versatile strap (in case the earloop does not work for her child).
These few incidents are a tiny fraction of our sales, but the urgency case of Kenneth got me thinking: “wouldn’t it be a good idea to allow purchase of extra straps, so that people going for critical mission can bring along a replacement strap in case it break?”
What do you think? is it a good idea to sell extra replacement strap on our site?

Where can I buy replacement straps and orings? Don’t want to have to change mask – I love mine…
Hi Tim, you can get replacement earloop straps from our online store here:

When replacing a filter, the O ring which holds the filter casing in place snapped as it had frayed. I have been searching for where the buy replacement O rings. Does anyone know where to buy these? Otherwise the mask cannot be used again which would be a great shame as I have three people who have asked me about it and am going to send them the link to the website.
The o ring holding the filter cover can be replaced by a normal rubber ring of similar size. Should be easy to find from shops selling office stationary.
I broke one of the straps too and would love it if you sell replacement straps.
Thanks Ken, ROhan, looks like the strap will be for sell soon 😉
Yup. Its a good idea 🙂
These straps do last quite long, and dont really break unless you are rough with them ( I am and I have broken one after almost a year of use ! )
Hi Francis,
I actually had a look to see if I could buy the straps off your website before giving you a call, but could not find it for sale. It’s easy enough to self-replace and I think that if you use the Totobobo long enough, you’ll need to replace the straps at some point in time.
