Often confusing to try and match manufacturer retail codes against HSE grading, but Moldex have a plainspeak guided called Good to Know, especially pages on Gas Filter Classes and Protection Levels and Particulate Filter Protection Levels.thread is meant to be discussing masks
That is A2P3.3M 4255+ maintenance free respirator
That is A2P3.3M D8095 filter
FFP stands for Filtering Facepiece and is not a full face mask, so eye contamination cannot be prevented (even by wearing safety glasses).type FFP2
6059 filters only to A1 inorganic and organic vapours, but 5935 does filter to P3. Eye protection as above.half mask with 6059 + 5935 filters
Chinese mask that reveals no filter grades but instead uses reassuring words like professional and high quality. At £80 it's pricey compared to others that declare filter grades to UK/EU standards.Amazon - PT-101 Respirator & P-A-3 Filter Set
Spanish filter graded B1E1. B1 is fine for inorganic gases and vapours (chlorine, hydrogen sulfide and hydrogen cyanide) and E1 for sulphur dioxide, but these grades are not equivalent to A and P filters for sublimated OA.
FFP stands for Filtering Facepiece and is not a full face mask, so eye contamination cannot be prevented (even by wearing safety glasses).
Just to add a little more detail to this -Chinese mask that reveals no filter grades but instead uses reassuring words like professional and high quality. At £80 it's pricey compared to others that declare filter grades to UK/EU standards.
Not that confusing I just went into screwfix and gave them the manufacturer’s part numbers and asked if they had them.Often confusing to try and match manufacturer retail codes against HSE grading, but Moldex have a plainspeak guided called Good to Know, especially pages on Gas Filter Classes and Protection Levels and Particulate Filter Protection Levels.
Find hse.gov.uk/EU filter codes on page 45.

Commonality of grading to UK standards would give the consumer confidence, but ASTM E2952 is a US standard which can be accessed only by paying $98, so although it reads impressively, the buyer is none the wiser.ASTM tested E2952 - 17 Standards
This is disengenuous and not quite the same as complying with the UK HSE & EU filter code, in which case it would read A1P2 or A2P3, and so on. The advert does quote CE certification, which is an EU assessment of safety (not UK), and also NIOSH, another US certification of safety. Sounds good, but...filter grade at P-A-3
Anyone new to this game should be able to ask for filters based on the AP rating and not on a manufacturer's model code. Easier for the buyer to cut corners and use an inadequate FFP mask, because they're usually described as such, but commonality of AP labelling would reduce consumer error and increase safety.gave them the manufacturer’s part numbers
Confused me! (some years ago)Not that confusing
Agreed but I'm more interested in the ASTM E2952 standard being safe and assume (being Global) and from the USA (they label everything) should be fine for our needs?Commonality of grading to UK standards would give the consumer confidence, but ASTM E2952 is a US standard which can be accessed only by paying $98, so although it reads impressively, the buyer is none the wiser.

In fairness I have more faith in the manufacturers technical department than some spotty scroat behind the counter of my local screw fixAnyone new to this game should be able to ask for filters based on the AP rating and not on a manufacturer's model code.

That’s what I did in the end. There’s a few sellers on eBay selling the 3m full face for £64 which is much cheaper than most retail places.Just to add a little more detail to this -
It states filter grade at P-A-3 - P-A-3 Dual Filter Set - Combination Organic Vapor and Particulate Filter - ASTM Tested (Replaces T-61 & PD-101 Masks)
ASTM tested E2952 - 17 Standards (NIOSH certification application pending)
The mask is well made* and seals very well and protects vision, you can swop out the filters for 3M if you wish.

*The Moldex mask fell to bits.
I'll be keeping this Chinese mask for the woodshed and looking at the 3M 6000 full face and filter set just to be 100%
The combination I use offers the same protection as yours, ABEK1P3. Recommendation for replacement is when breathing becomes difficult for the particulate filter. For the ABEK1 is similar, any trace smell or taste of the substance during use or six month intervals as once opened they are still absorbing. An airtight container may help extend the life.The other trick i can share if using filters is to store them in an air tight bag, i was told it would significantly extend their usage and life. Mine are nearly 5 years old and still fine although just bought a new set as a treat but this year doing treatments they worked fine.
Aka P3, so a good combo with the A2 filter.3M 5935 pre filter
P represents particle filtration graded 1 to 3. Of these, 3 is the most effective, so this mask would be ideal for dusty DIY.
This is the model recommended by the manufacturer and available at screw fix.Just an FYI..I sent a mail to 3M regarding oxalic use and what they recommended, this is the reply.
“Based on the information provided and without prejudice, I would suggest that you evaluate a 3M 4255+ maintenance free respirator or a 3M SecureClick HF-800 reusable half mask fitted with 3M D8095 filters. Details are available via our website listed below.”

Actually, this is the mask that I use. I am not cavalier about my health or anyone else's for that matter - the mask is a good quality, comfortable mask to wear and with a P3 filter I have found it more than adequate for use with sublimated OA. It has the following properties:
