Dust mask and glasses

[LONG_KEELER]

Anyone know if the world has found an answer yet to fogging glasses ?

Does the anti fogging spray stuff work ?

Thanks in advance.

Yes. I was given a thing like a WW2 gasmask with a filter. I believe it is used in nuclear industry amongst other places.
The thing that makes it work is a valve... You breath in through the filter and out through an exhuast so the moisture doesn't accumulate.
Pretty damned good at protecting your tubes as well..

WARNING! If anyone finds a WW2 gas-mask, do not use it - they may contain asbestos!

For fogging problems, apply a few drops of neat washing-up liquid on the inside of the visor, then smear around and polish off with a clean cloth - not paper towel. Also works on mirrors.

Do you mean the standard paper "nuisance dust" masks? The problem with them is that they exhaust air around the edge of the mast, particularly around the top where it doesn't fit around the nose - and blows the breath straight onto your glasses. A slight improvement is a paper disposable mask with a valve in it, for a few pence more, but the real solution is a rubber mask with separate filters attached to the sides. B&Q sell one, though no doubt they're cheaper elsewhere. They have different grades of filters for dust vs actual toxic stuff - I just have the cheaper dust version, but they're interchangeable on the same mask. I haven't yet needed to replace them, just hoover the dust off from the outside (follow the instructions on replacement if you're dealing with toxic stuff, though, I just have router sawdust to worry about).

I have no problem with steamed up glasses with this mask, and find it quite comfortable.

I use these Filterspecs http://www.toolstation.com/shop/Filterspec/p81323

They are excellent and actually work. I was really dubious that they would, but I use a dust mask, glasses and ear duffs for work so I thought I would give them a go and was very surprised.

Nigel, where did you get this info ? Just wondering if asbestos was in the gas mask filters we used in the 60's & 70's.

I thought it was common knowledge, but worth repeating. I wouldn't worry about the past, there is bugger all you can do about it. Speaking as someone who broke up an asbestos garage roof in the back of a transit van.

No I had never heard of it before. Probably the reason why we were told to never open the filters.

I've certainly heard the same thing.

I use a full face shield, no fogging problems at all.
