With the haze in Singapore turning bad, the perfect mask depends on the fit to each individuals face as much as the N95 compliance. I test several masks to see which is the most effective.

We have started using our Totobobo masks, and changed the filters for the first time after 7 days of usage in Malaysia, plagued by the haze coming from Indonesia. So far we are satisfied, it works well and the filters are getting gray as expected!

Totobobo is an popular respirator within local leisure cycling communities – because Francis is a green commuter himself, using his bicycles whenever he can and promoting safety through road/infrastructure design. And safety through design was really the theme behind the Totobobo, although he has not said it before openly about the concept of his Totobobo respirator.

I’ve bought my first Totobobo way back in June 2011, when the haze that year was still around the June period. I bought my second set in Q1 2014, to meant to replace the very first set, which to date in September 2015, I have yet to decommission as it could be a standby unit in case I lose the newer unit. I bought my Moldex initially in March 2014, during a short-lived haze period while I used the my second set of Totobobo.

Testing fit-factor of F96 and cotton pad. F96=200, cotton pad = 2.3. F96 is nearly 100 times more protective than cotton pad.

Totobobo mask has a good feature where you can customize the mask (and the ear loop) by reshaping it with hot water / hair dryer. This is a very crucial feature, a mask that do not fit your face is not an effective mask at all. The rim of the mask is integrated with silver ion which is an anti-microbial agent.
Another good point it’s reusable, you just need to change the filter. When it gets dirty you can wash them.


DIY emergency Air filter

Project Oxygen:

DIY air filter, you need a water bottle, 2 T shirt, 2 pieces of threads, and a knife.

Oxygen is always in the air even under heavy smoke, the problem is that the air is contaminated by smoke from the forest fire.  A good fitting respirator, such as N95 mask, to filter out the smoke particles is a common solution. However, under emergency situation, it may not be possible to distribute N95 masks to all who needs it. Further more, even if the mask is available, it is not easy to ensure it is fitting correctly. A non-fitting N95 mask is not effective.

Here is a simple idea to transform readily available material into an air filter, which is able to filter the air for breathing safely.

To create this DIY air filter, you need a couple of T-shirts and a plastic water bottle plus a couple of strings. Based on our test with a professional machine (Portacount Pro 8038) such DIY filter is able to reduce air pollution up to 40 folds, achieving a filtration efficiency similar to N95 masks. It is capable of bringing down the fine particles (PM2.5, PM10) from super hazardous level (PSI 1000) to moderate (PSI 75).

Here is a step by step guide:

How to DIY a personal air filter from water bottle and T shirts?
1) Cut some holes in the middle section of a water bottle
2) Fold up and roll a couple of T-shirt around the water bottle. (the one in the following video create 20 layer of fabric)
3) Tight the top and bottom part with a string to seal the gaps
4) suck air from the water bottle.
5) breathing mouth in, nose out.
Working principle:
Polluted air enters the bottle through the many layers of T Shirts material. Most fine particles will be trapped in between the many (20+) layers of fabric. We measured with a professional machine and the pollution can be reduced by 40 times (97.5% filtration efficiency). This is equals to bring the PSI down from 1000 to 75, a substantial improvement of air quality from readily available material on hand.

Note: The idea of DIY water bottle air filter has been demonstrated in our Lab in Singapore to show that it is effective to cut down air pollution. However different fabric material has different filtration characteristic. This idea has not been certified by any authority. User agree to take own responsibility for the use of the idea.
