Way more important than not drinking the water is not breathing the air. Please wear an N95 when you lock yourself in a tiny steel tube with hundreds of others. If not for your safety, do it for others.

I just keep wearing an N95. I've had maybe 3 infections in 5 years.

Higher does not necessarily mean better. Higher grade filters filter more in each pass, but can overall provide worse performance as the air flow rate goes down. The air is being recirculated in a portable unit or in a standard domestic duc

Ventilation and air purification have a strongly theoretical basis and there have been real-world studies showing a clear benefit. https://cleanaircrew.org/ https://www.cleanairschools.com.au/

Clear exists because the TSA have made life bad for everyone. Economy class passengers in Australia have a better experience than Clear passengers in the USA and don't have to pay extra for it.

Perhaps, maybe, mass infection by a virus that affects the brain and vascular system has consequences for society.

Let me get this straight: you are selling a guarantee of maximum price for a medical service? You are selling health insurance.

The most unbelievable part of this story is that he claims to have read it out to the family.

Weird comment about masks not working for vinyl chloride. Whilst it’s true that a particulate filtering mask (N95) isn’t enough, you can definitely get some protection from an organic vapour cartridge fitted to a reusable respirator. See h

I’ve had lawyer patients just giggle at the fact that I’m near the top of the income rankings in Australia. ‘Clearly doctors don’t hide their income very well!’ Patients pay less, and I get paid relatively more in Australia (less in absolut

More in private, but not the difference on an hourly basis is not necessarily that much.

That’s why most patients (at least in the practices where I have worked in Australia and the US) get an EMG first, to localise the lesion.

I might be totally misled, but I think of it as a parallel resister circuit. One area of low resistance is extremely significant.

Yes correct! Thank you!

The Melbourne climate I was referring to needs heating 9 months of the year. The vast majority of houses have very simple, inefficient gas ducted heating. Rightly or wrongly, humidity control is generally not well considered. I was going to

I've had very good luck with the CableMatters USB-C to DisplayPort cables! I've used a couple of them continuously for the last 3 years.

In Melbourne’s climate where piped methane costs 1/3 per kWh that of electricity, but heat pumps are 300-500% efficient and you remove the duct loss, for most people their heating bill drops by 2/3. Add solar self consumption and

There are floor mounted units that can be recessed into a wall. Alternatively, ceiling cassettes (not ducts) can be good. https://www.mitsubishielectric.com.au/wp-content/uploads/202...

I've seen that terminology used on US websites, it took me a while to get my head around. In Australia it would just be called ducted reverse cycle. In the vast majority of cases it would be "ducted ductless" I guess: outside

We are talking about the tiny amount of water vapour left on the interior condenser. The idea is to bring that back up to room temperature so that it doesn’t stay there near the dew point. The total amount of water inside the house does not

That’s double the price I paid here!

For an existing dwelling, the best solution is probably mini splits (wall mounted) combined with decentralised heat recovery ventilation as required. Ducts running in an insulated space are sources of huge energy loss.

That actually sounds like a perfect climate for it.

Exactly. In this example, which is pretty common here, I installed 1 in the living area and then 1 in each of the bedrooms.

The no 1 reason I bought the Daikin model referenced over the comparable Mitsubishi Electric is that it has the ‘MOULD PROOF’ function. It runs the fan automatically after you have had it in cooling mode, to evaporate the moisture build up

I take your point, but installation faults in central gas heating are also very common, but perhaps less obvious. The main one I’m thinking about is poor sealing or placement of the return duct, causing entrainment of air from the wall cavi

In the Australian market, the efficiency of the in ceiling or in wall units is lower than the high wall units. They are also much cheaper to buy and install.
