Face mask filters - re-use ?

Face masks are of not a general community use at this time but just in case or for those that use these might be useful to be aware that while within the medical environment face masks are strictly disposed of after a certain time , domestically this may not be required and it seems quite safe to sanitise the mask and keep using the same mask - good for the family budget as quality masks are quite expensive 

The recommended method from those in the know is to merely bag the mask in a plastic bag and heat up to a little over 70 degrees C for 30 minutes

I went to the chemist today and asked the assistant "what kills the Corona Virus?"
She replied to me "Ammonia Cleaner"
I said "Oh, I am sorry, I thought you worked here"

I sure as hell wouldn't be wearing a recycled face mask.

 

I can't wear them anyway. They make my glasses fog up.


I think they were talking about the fibre versions that cover the mouth and nose not the whole face gas mask types 


Yes. I was talking about the same thing, thank you.

For domestic use people pay $100+ for a mask ... for their own use some may choose to sanitise but i would not be surprised if they design the masks to block up if heated over 70 degrees C ... or if some manufacturers offer a model that is manufacturer sanctioned for proscribed sanitising 

 

A private car is not an ambulance , but a private car can still deliver a mildly injured person to hospital safely.

Re: Face mask filters - re-use ?

i'm yet to be convinced wearing a $2 mask will protect you from anything to do with a virus

 

i see all these pictures of people wearing little cloth masks that hook on their ears.

 

the particles of virus are micro scopic, would go right through them

 

i'm not even sure my spray paint mask with its canisters would do the job, paint dust is big in comparison to virus germs

 

masks will however stop some spread of sneeze or cough i guess

Seemingly , however there is a physics qurk called " diffusion" that dooms a virus to get snagged on HEPA filters even though technically the holes are larger than the virus -

Are you the resident virus expert now?

Oh, that's right, you read it on the internet so it must be true.

Signatures suck.

Re: Face mask filters - re-use ?

I agree roges, there is a lot of merit to what you are putting forward.

 

Unfortunately however, the general population is fallable and won't adhere to correct enough procedures no matter how well trained.

 

Basically people are not reliable and generally lazy for authorities to trust in proper procedures to be able to recommend solutions requiring strict methods, hence it may give a false sense of security.

 

Whilst you and I probably come up with very effective methods in our lives, it is not something that can be recommended to the general public.

Kopes - rely on your own understanding - not that of the ' student '.

 

The news about novel coronavirus continues to develop. It’s important to take sensible steps to look after yourself and your family.

  • Keep an eye out for updates from reliable sources such as the NSW Government website
  • If you develop a fever, cough, sore throat or shortness of breath within 14 days of overseas travel or are in contact with someone else who has Coronavirus, seek medical attention: call your GP, Healthdirect on 1800 022 222, or in an emergency, your local hospital emergency department
  • Protect yourself and others: clean your hands regularly, cough or sneeze into your elbow or a tissue. Face masks aren’t recommended for people without symptoms. Importantly – stay at home if you’re feeling unwell. 

At Service NSW our customers are our priority. We are putting in extra measures to ensure your safety. We have improved cleaning and are providing hand sanitiser and single-use pens at all our centres.

We encourage customers who have any of the symptoms listed above to consider doing your Service NSW transactions online.

 

Appys to Vic also.
