I completely agree. I don't think most people are aware of the shelf life, the need to keep them sealed religiously, or the need to replace often. I see so many masks just hanging on a nail in shops.

These masks are really important in my profession too for protection from infectious substances. We wear them when going to farms with disease outbreaks in confined areas or when working with diseased animals in experimental conditions.

You're right, I don't see the part number on the HF website. I guess I must have cross referenced the part number by getting it from Arlo's post.

I completely agree though...if I was buying it from HF and did not have the part number so I could look up the stats on the respirator, I prob wouldn't buy it. Especially because it is HF. But now we can put this to bed because we all know what the actual Gerson number is and know it's a legit respirator.

shine you can wrap a towel around your head if you like lizer . i really dont care. i use 3m because it is sold here. i have nothing against gerson but they are not sold around here. but i do know about paint and the damage it can do . that is why i use a hood .

i prefer my bullard hoods . disposable and relatively cheap.
used gerson tack rags for years but they got too sticky and left residue .

If it's effective against iso's it's going to be more than just a latex and saw dust mask. It's p95 and organic vapors. A lot of masks aren't even effective against iso's based on reading I did several years ago.

Gerson's not a bad brand, and the fact that HF is selling it doesn't necessarily make it any worse. You can pick up a few name brand things at HF.

I'm pretty religious about sealing and burping my respirator....even if I have to run in the house for just a second or say...call Barry in the middle of a shoot.
No I know gerson is a good brand we use them at work or buy the SAS BUT I did not know if they had different part numbers for different materials.
You did your home work, so you know what you are getting. (I did not know)

Lizer Ask yourself this. What's the difference between Gerson and 3M if both produce an organic vapor cartridge that passes the NIOSH threshold testing for effectively removing isocyanates and organic vapors (and are both NIOSH approved)?

To answer that question, one is a company who's sole business is air filtration, while the other is a company that buys up everything it can and then jacks up the price 200%.

I don't have a preference for either...I own both 3M and Gerson respirators (none purchased from HF though) but I think it's silly to discount something merely because it's not 3M.

shine ask yourself this. is 20 dollars too much to pay for a lung ? using old or cheap respirators is insane . i use 3m . period . and they get tossed after each job.

Auto paint store is not going to sell one rated for latex's or saw dust, maybe they are the same but I would want to know if I was using it.

We have a company on hire full time the does surprise and mock OSHA visits, so we know we are in legal compliance and one of the big things is the respirators in the building where stuff is made, even though the air has been tested for eight hour periods every so often and we really would not have to wear one when blending or running the filling machines, we require one at all times in that building and we supply a new one every Monday And have written documentation that every 3 months the employees are taught to put the mask in the bag, burp it and seal it at every break or end of day.

We buy case lots each month and for the measly $10 a unit it costs me, I will happily spend the money on top of this in the one building we have $10's of thousand of dollars in ventilation and if you are working at home, you most likely don't.
This is the same respirator as what he's buying at HF.

shine i buy a new mask for every new job for primer. i have a hood for everything else. using a mask that is 30 days old is insane unless it is kept in the bag religiously . i would not trust any bargain mask .

Technically speaking you're supposed to replace those filters after 30 days, but I don't think anybody does, and I think that's also because most people prob don't seal them up. To tell you the truth I feel paranoid if I've left my mask sit out for one night. For several months...I wouldn't trust my health with it.

thanks arlo

Lizer charcoal is just the common substrate when used with organic vapors. Yours is for organic vapors so you're good to go. However, yours also says usable with isocyanates which is perfect, because normal charcoal filters don't stop isocyanates so you're still being poisoned by these while painting, even though you don't smell them or the paint. Eventually you could develop bad hypersensitivity to isocyanates and it would feel like burning when you breath. Iso's are not in the epoxy you will be spraying, but they are in 2k primer and clear coat, and a marginal amount in base coat if you added clear coat activator to it, which contains isocyanates.

In fact tell me what filter that is so I can be sure to get it...my full face respirator is a Gerson too. When I do large sprays with isos I wear full body protection...tyvec suit to cover all skin and full face respirator. I don't want any coming in through my skin or mucosa.

Also, the substrate in those respirator filters are activated by air. They are continually reacting with air binding up anything in it the substrate has an affinity for, so keep it sealed up in a ziplock bag whenever you're not using it, this will keep the filter substrate from being constantly activated.
