belt pack came from a safety shop in fairy meadow , the faceshield came from 3M directly, retails for $1499
work paid for it for me so I guess they are keeping me on!

Mmmmm, interesting. I initially thought (hoped) when I saw this thread with this new style of respirator that 3M might actually price these units at a more realistic level. By realistic I mean a hell of a lot cheaper. I have a 3M Dustmaster and reckon that it could be manufactured in China for about $10! (it cost me ($850) There really aain't much to them. The face mask component, for example, is no better than a standard face amsk that costs $20 - $30. If you showed it to someone who knew nothing about them I'm sure they would guess the price to be around the $100 mark. These new ones look slicker but I'm sure are also very inexpensive to manufacture. So how on earth do they end up retailing for $1000 + ????? Unfortunately they are by far the best thing on the market, especially if you need to wear it all day. But it really does upset me they are so bloody expensive. I usually don't like the fact that Chinese manufacturers rip off designs from elsewhere and sell them at a much cheaper rate but in this case the 3M monopoly on this style of respirator should be challenged. And if it was I bet the price would very quickly plumett. Perhaps the price reflects the fact the respirators are designed for industry and not the humble turner.
Gripe over, off to bed

So it's $1500 plus the belt pack? Jaysus, I could buy a sexy lookin' copper & brass diver's helmet and a split system aircon to feed it for that. Looks and sound like a great bit of kit but really that's an absurd price for what it appears to be (a bunch of molded plastic and stuff).

I looked at that as well and could'nt justify the price, so i looked around and found this
PAFtec Cleanspace® 2 Respirator : CARBA-TEC
found it a BOC for $445 plus the $80 for the mask - comes in 3 sizes and 2 styles.
but the best part is the battery last a full day its not always running like some respirators just when you are breathing. fits nicely under my face shield and does a bloody good job, no more coughing up trees
found this on youtube and this kinda sold it as well PAFtec CleanSpace® Carpark Robustness Test - YouTube

it has a rechargeable battery its been lasting me 10hrs, it says it last 6-8hrs then just plug it in to the power point
and yes it has a filter but what i have read they done need changing that often. I got a filter saver for it as well that sits on top of the filter and pro longs its life as well

Good rant, Brendan.
If Australasia can produce four of the best woodturning lathes over the last couple of decades I can't see why we couldn't do something better on turning mask-respirators, at least price wise.
Triton had a go. Not sure what happened there.
The collective ingenuity of the members of this forum must be able to come up with something that is more affordable.
The basic design is a high impact face mask + a skirting to contain and direct positive air flow over the face + a supply of filtered positive air pressure/flow or fresh air from outside.
There are two options on the last component; tethered, which works OK in the vicinity of the lathe, and self contained with the filtration and fan unit on the mask or on a belt or back pack.
The first component is readily available at mass produced prices. The impact rating, comfort and economic replacement of the shield (they all scratch) are the main consideration there.
Adding the skirting is a fiddle, like finding a glue or solvent that takes to the plastics used in the mask, but nothing beyond most of us. Various designs for the skirting may be needed to suit personal preferences.
The simplest option for the clean air supply is a tethered arrangement. It may not suit everyone, but I found it worked well for me in and around the lathe, bandsaw and sharpening station, where I spend most of my time. In mine I ran a supply line of flexible medical grade hosing along flying fox (zip) lines to an off-the-shelf air filter unit, like this. The downside is the limit of the tether. The upsides include the vary large surface areas of the HEPA filters in off-the-shelf air filter units, which means less frequent need to clean and replace these larger filters, the relatively cheaper cost of replacing these more standard sized filters, and the quieter running noise levels inside the mask because of the larger/slower fans inside the filter unit.
Here's my version of that system that I have been using now for quite a few years.
Provided your climate doesn't have extremes, fresh air from outside delivered via a fan unit through a similar arrangement could be another economical variation of the tethered option.
And for an 'onboard' filter unit option, I don't imagine it would be beyond the brains trust to come up with an economical solution there. For example, hook one of these 12v units* to either one of these small lightweight lithium-iron batteries (buy two and recharge one while using the other) or to one of these longer lasting but heavier batteries.
If I was to put that combination together I'd be mounting them on a back-pack arrangement. Strip it down to just the harness and frame. The local op-shop usually have a bucket full of them.
Then, for the best of both, a dual air supply option could allow for tethered operation while in the main workstation zones and self contained for elsewhere...
At worst, a DIY solution might cost between $300-400, and that allows for a few hiccoughs along the way. Cobbling together a DIY solution from mass produced components will provide the most economical solution. To manufacture a customised commercial product for what is a limited market is always going to cost more. They have a lot of compliance costs and OH&S issues to get right. But, I still can't see why it should cost any more than $500-600 for a premium retail product.
* The cubic delivery capacity of that unit is not specified, so might be insufficient. The availability of replacement HEPA filters and getting access to change them may be another issue. I would also want to be able to turn off the Ozone feature... yes, it kills germs, but is also unkind to other living thing.Stay sharp and stay safe!
