Does anybody have a recommendation for a filter mask that fits under a kemppi beta 90p (the old shape one, not the new one). A mask with replaceable filters though, not a "use once" type.
The Stealth mask:Can someone point me towards the exact filters that have been purchased.
Looking on the GVS site and cant see anything described purely for nuisance dust. It will be useful to understand what we are considering.
For welding, anything fitted with a P3 filter will be very good as it will protect against both dust and fume. As usual with orinasal respirators they are only as good as the seal formed around your nose and mouth and will require you to be clean shaven
That advert is incredibly misleading and not very clear at all. P3 is what is required for welding fume and dust.@Parm These are the nuisance filters GVS Elipse P3R Half Mask Respirator Nuisance Odour Welding Filters 5060233800155 | eBay

You've lost me a touch . . . I don't think they claimed a colour indicated the filtration class, just that the bit of the mask that carries the replaceable filters is red and black.
I enquired about the GVS mask and you replied to my post with details of a completely different product ?You've lost me a touch . . . I don't think they claimed a colour indicated the filtration class, just that the bit of the mask that carries the replaceable filters is red and black.
It comes with replacement filters:
Slapped all over the packaging is:
- FILTRATION STANDARDS: Conforming to BS EN 140 and BS EN 143 P3R standards to filter particulates with 99 99-percent efficiency at 0.3 microns and above
Trend ML Stealth Dust Mask P3 Reusable Respirator, APF20
Thanks @Parm . I'm pretty sure you're right and the black layer is activated charcoal. Might be desirable for some but I have no sense of smell so not really necessary.That advert is incredibly misleading and not very clear at all. P3 is what is required for welding fume and dust.
Ive no idea what the P3R is on the first link. I can see some black on the filter but then would expect to see some information on activated charcoal and what it can do, how it can be used etc etc etc etc.
Looking deeper the R is for nuisance odour - its not a classification system i recognise, nor is it a test requirement for the British Standard that these things have to conform to
Just ensure that any filter you buy is P3 as this is the only testable criteria. The rest i suspect is just snake oil marketing
You appeared to ask for details of masks posted - the one I posted was the Steath - so I provided some details.I enquired about the GVS mask and you replied to my post with details of a completely different product ?
Same thing, ive no idea what a R classification is, never heard of that before
Like I said I do not recognise RYou appeared to ask for details of masks posted - the one I posted was the Steath - so I provided some details.
I believe "R" indicates "re-useable" ("NR" being non-reusable or single shift) - many manufacturers seem to use it to indicate such use.
Colour code for P3 filters is white - which the stealth filters are.
Because every supplier flogging fliters with "R" in the designation says they are "reuseable". To be honest, I was more concerned with the "P3" and/or "APF20" classification.Like I said I do not recognise R
NR I’m highly familiar with
these codigns are to help the general public. I work with this on a daily basis and didn’t understand, no idea how long it took you to find this out
