“Coronavirus could be spread by air-conditioning and may be more contagious than previously thought, scientists believe after finding traces of the virus in hospital air-duct.”- reported by DailyMail

In 2003 during the SARS crisis, the worst affected building was the Amoy Garden at Kowloon Bay. The virus was spreading to a cluster of bathrooms sharing the same drainage pipe.

Here is an example DIY project for a “bathroom drainage cover” to prevent the airborne virus from spreading through the share drainage pipe to your unit.
The main components are the filter sheet and a plastic holder, which can be converted from any takeaway plastic box. You can use tape and/or rubber band to wrap the filter over the opening and sealed. Air coming from the drainage hole will be filtered by the filter before it can enter the bathroom. There can be a tiny bit of leakage at the base of the plastic box but most of the air will be filtered. The key is to reduce a significant portion of the virus and reduce the potential damage.

The photos are self-explanatory. If there is any question please leave a comment below. I’ll try to answer asap.

Pauline mother’s totobobo mask

Pauline’s 90-year-old mum and her helper wearing the Totobobo mask as they set off for the activity centre which mum attends 5 days a week.

Thanks to Pauline allowing us to share her letter and the photo of her mum.

Dear Francis,
My family and I have found the mask comfortable although it is a bit fiddly to change the filter and adjust the straps. 
Everywhere I go, folks have remarked the mask looks comfortable. However, they flinch when they first hear the price but calm down after comparing this to the cost of wearing surgical masks daily. I will certainly spread the word about your wonderful product and am greatly puzzled why your product is not known to more Singaporeans who have been desperately looking for masks!
Best regards,
