Avoiding asthma trigger with a Filter mask

Fitting mask: a just-in-time solution to cut-off air borne asthma triggers

Disclaimer: Asthma triggers are various and depends on patients. This article is not intended as a substitute for medical advice, diagnosis, or treatment. Always seek the advice of your physician or other qualified health care professional regarding any medical questions or conditions.

Many asthmatic patients are given a prescription drug and inhalers to control their asthma condition. While these medications are helpful to control the symptoms of asthma, some patients prefer to limit the use of medicine to avoid potential side effects. Recent research also question the conventional wisdom of using “preventive” drugs to control asthma.

If you belongs to the non-drug camp, you may consider using a fitting face mask to block air-borne asthma trigger “just in time” to prevent it from flare out of control.

Asthma triggers can be broadly divided into 4 categories:
– air borne triggers (irritants, allergens, cold air)
– allergic triggers (non air borne, i.e. cockroaches)
– psychological triggers (stress, strong emotion)
– physiological triggers (exercise, excessive laughing, crying or even sneezing)

Asthma airway

Airway contracted under asthma attack

A great portion of asthma attacks are triggered by air borne stimuli. Triggering stimuli such as irritants, allergens or simply cold air enters the air way (bronchial) causing a strong reaction, inflammation and/or narrowing of the airway tubes that leads to breathing problems. Most asthma attacks are mild, but even people with mild asthma can have a fatal attack. More than 5,000 deaths a year in the USA are attributed to the condition.

Symptom avoidance is a well know strategy for asthmatics. It is possible to cut off or reduce air borne triggers with a properly fitted filter mask (respirator). However choosing a suitable face mask can be a complicated issue.

There are two types of portable respirators in the market: reusable respirators and disposable respirators. High quality reusable respirator provides a better fit, but it is more bulky and less likely to be carry around, reducing the usefulness. Disposable respirators are more compact but can be easily distorted after use. This can affect the face-fit in subsequent use. Both types of respirators require a “fit-test” by professional to ensure a proper fit. However, it is not possible to conduct a “fit-test” each time when the mask is needed. Therefore the fit quality during use remains as a mystery.

Above dilemma is finally solved by TOTOBOBO mask, in a remarkably simple and intuitive way. First the transparent respirator allows you to see through the mask clearly and decide if the mask fits or not. Such visual check is easy to achieve each time when you need to put on the mask. Secondly, the mask can be trimmed to suit any unique face, including children’s. Finally the high quality reusable mask can be folded flat and fits into a shirt pocket, carry around and ready for the action whenever it is needed.

Currently TOTOBOBO mask is the only solution providing Easy fit-check, Customized fit and “Pocketability”. These are important factors if cutting off air borne triggers is in your plan against asthma attack.

Do consult your physician to come up with an overall plan for your own situation. You may consider TOTOBOBO mask as part of your overall strategy to reduce, but not to replace the use of medicine. A small percentage of patients’ asthma triggered by high moisture air might become worse after putting on a mask.

Dr. Anil Simhadri, London, UK (2012)
I am a doctor /physician in the UK at UCL, and bike daily in london to work using totobobo mask. I also suffer from asthma using a ventolin inhaler. I have been using totobobo masks since feb 2010 when I placed my first order and find them very useful. My cycling performance with regard to speed of cycling has improved. Previously I might cycle 6 miles in 1 hour. Now I cycle 6 miles in 50 minutes. The mask helps improve my control of asthma. Asthma is a disease of airway hyper-responsivesness. The tracheal airways are hyper-responsive to various triggers. Pollutants in the air as in inner city london can trigger the airways to constrict or narrow. Totobobo masks prevent these pollutants reaching the airways and so help remove the “trigger” for asthma.

Teresa Lam, Hong Kong (2008)
“After trying the mask for a few weeks, I can say the TOTOBOBO mask does feel very comfortable. I’m quite positive that the mask had helped to reduce my asthma. The masks I used to use were not very air tight so most air I inhale would have gone through the side of the mask instead of any filtering.”

  3. With winter approaching, both the cold air and the particle pollution were triggering my respiratory symptoms. Also I work nights, and I go to a nearby workout room to exercise. The late night cold air, even just walking outdoors for a few minutes, was causing respiratory issues and interfering with my workout. Though feeling a bit self-conscious about wearing the totobobo mask, I wore it outdoors while walking to and from the exercise room. The results were great – was able to start and end my workout without respiratory issues.
    Also, I must say that the transparent totobobo mask is actually not that noticeable from a distance.
    Thank you for a great product that helps me breathe easier.
