I didnt find any of them worked very well.
The best thing i found was fitting the surgical quality mask firmly - and then I would leave it on all day. only taking off in my lunch break
I used to drink water during the day via a straw poked under bottom of mask. But I wouldn't move the top part once it was fitted firmly.
Yes Vegemite Kid there is NO perfect solution & often we have to work with what is available as a compromise.
I had to chuckle at your straw ... was that "the last straw" for you ?
I obtained some special medical adhesive 'foam' for some medical folk & that helped significantly they reported. Some of the photos of long suffering medical staff ( nurses ) I've seen have been nigh on horrifying - so much suffering by those poor girls/women.
One device ( again with up & down sides ) that I have here is a PAPR of my own design which numerous medical folk I know have seen & then wanted - it solves most of the issues mentioned earlier by some.
Positive air pressure is fed to the inside of the masks including N95 & related, Looped, tied, duckbills etc etc it matters not as it is adaptable.
But to the point - because of the positive air pressure inside the wearer's mask ( provided by the belt or shoulder mounted unit ) the wearer is fed filtered COOL fresh air so no sweaty face.
And the inside mask pressure also means not having to 'suck' air in via the filtration layers of the mask which is where normal viral impact load occurs.
It means a more comfortable & less tightly fitting headgear is required. Varied face shapes & mask shapes are also more readily accommodated whilst retaining a proper seal.
Air flow velocity, is easily adjustable by the wearer/user.
If resting it can be throttled right back and then if wearer is actively exerting simply adjusted up to provide a higher throughput volume and again COOL FRESH filtered air.
The downsides? COST has precluded PAPR use in many/most situations.
And of course it is one more THING to have to be bothered with in a busy world.
Having worn it out in the real world I've had nothing but positive remarks & in this world of freaky fashion most people don't even look twice.
Mind you someone coming towards me sees ( if they even notice ) what appears to be pretty much someone wearing a mask - end of story. The small pressure/filtration unit is at waist level just out of sight behind my left arm but allows me to reach and adjust if required.
And it is virtually silent.
The cost of commercial units sadly has been prohibitive & in fact the last PAPR I recall seeing was worn by an anaesthetist which gave me an opportunity to look closely at that design.
Meanwhile locally covid is reportedly on the climb again and the death rates have jumped significantly.
Apathy will help the rise as many folk I see prefer to ignore the reality & just want to forget it exists ( understandable.. but...... )
And what will follow Covid?.... I saw an article about a fungus that is causing serious problems and dealing with that might prove even more difficult.
As I glance up from the keyboard I notice the sun is still shining so guess it's time to go check out my LiPo modules that are presently sucking up any 'goodness' they can manage.
They'll provide a feed for all the lighting I need in this room in hours of darkness.
Hmmm wonder what tomorrow will bring .....
