What do the different numbers of N95 masks mean? i.e. 9211, 8511, 7048, etc... and is it recommended to get the ones with the exhalation valve or not? Everytime I go to buy some I back off because I don't want to get the wrong kind. Thanks, Dennis

HI Wraith,

We have some good info on masks here:

http://www.superflutalk.com/forum_posts.asp?TID=978&PN=1

Let us know if you still have questions. 

I know, it's a very confusing issue and I was totally confused by all the choices too.

BTW: I chose the exhalation valve for comfort.

I love the exhalation valves too, makes breathing much easier imo, and reduces dampness from breath condensate in various weather conditions.   Some new valves are nicely slightly pressure fit to to maintain the seal too.  I wear one while cleaning the house to reduce dust inhalation and its nice easy breathing.

Thanks for the link, I passed right by that one when searching somehow.

Can someone suggest how many masks they got?  I just need a rough idea of what I might buy for a family of four.  I got 10.  Cost like $60 or $70 for 10.  They are individually sealed.  Suppose to be better than the N95 type.  Should I get a bunch of lesser expensive ones and stock up?  Are others doing that?

Hope, I got a gross of 3M 95 masks and 2 boxes of 50 each procedure masks.  I am close to ordering several more boxes of procedure masks, just because I don't think 100 will be enough.  The quantity depends on how often you or a family member will be exposed to the outside world, what I call "Outlanders".  If rarely, then masks will not be a major necessity.

While N95 or better are what's recommended, who among us can afford a year's supply for our family.  My rational.... some protection, however flawed will be better than no protection.  YMMV

BTW: If you choose to order more masks, you might want to consider shopping around, that sounds a bit high unless they are P100's IIRC.

Sz Why would you think it necessary to have P100 masks that are oil resistant?  Also, I found it very surprizing on how short a time frame these masks are effective for from the info on the cdc/niosh website.  Only 60 minutes. That puts a whole new meaning on disposable I think if you're wearing them to go out in public.

Interim Domestic Guidance on the Use of Respirators to Prevent
Transmission of SARS
May 3, 2005

Respiratory protective devices with a filter efficiency of 95% or greater
(e.g., N95, N99, N100) may not be available in some settings due to
supply shortages or other factors.

In this situation, a surgical (procedure) mask should be worn. Surgical
masks will provide barrier protection against large droplets that are
considered to be the primary route of SARS transmission. However,
surgical masks may not adequately protect against aerosol or airborne
particles, primarily because they allow for leakage around the mask and
cannot be fit tested. The mask should resist fluid penetration and fit
tightly around the mouth and nose when properly applied to the face.

http://www.cdc.gov/ncidod/sars/respirators.htm

3Mô Healthcare Particulate Respirator and Surgical Mask, N95


3Mô 1860 Health Care N95 Particulate Respirator and Surgical Mask.
NIOSH approved as a Type N95 respirator. It meets CDC guidelines for TB
exposure control and is designed specifically for use in a health care
setting. Recommended by health care officials as precautionary measure
against the "bird flu" and SARS.

It has a soft inner shell for greater comfort against the face and, because
it's fluid resistant, it aids in reducing the potential exposure of the wearer
to blood and other fluids.

Bush's risky flu pandemic plan
By George J. Annas †|† October 8, 2005

On Tuesday, the president suggested that the United States should
confront the risk of a bird flu pandemic by giving him the power to use
the US military to quarantine ''part[s> of the country" experiencing an
''outbreak."

Planning makes sense. But planning for ''brutal" or ''extreme" quarantine
of large numbers or areas of the United States would create many more
problems than it could solve.

Not only can't we evacuate Houston, we cannot
realistically quarantine its citizens. The real public health challenge will be
shortages of health care personnel, hospital beds, and medicine. Plans to
militarize quarantine miss the point in a pandemic. (excerpt)

The enemy is not sick or exposed Americans --
it is the virus itself.

I got the N95 masks with the changeable P100 filters.

 

I wish I knew how long these filters were good for per use.

Hours or even days as soon you dont deal with a close contact of an higly infected patient - and the filter is not colmated by dusts.
Military nurses are fit with N(uclear)B(acteriological)C(himical) filters (id est a P100 filter as the first filtering device of the cartridge) - heavy duty gear for hours of exposition or even worse.

Thank you very much Anita. I appreciate the information very much.  I was overtired when I was looking up the info on masks last night and I mixed up a bunch of information in my head. I think my stress level is starting to get the better of me.

I do have the P100 filters...

are you saying that each set of filters can be used for hours at a time?

 

I thought I had read somewhere that they were only good for about 60 minutes, but I cannot remember where I'd seen that.

Its not as plain - and there is no rate in fact, only recommandations and tests ... P100 in itself means nothing, the construction of the filter piece is the most important to consider.
A disposable cup/shell N95 ...P100 mask looses its ability to filter with use, perspiration, dust, liquid projections, ... from 30 min to 3 hours. Besides its better to discard after use in close contact with an infectious patient.
A P100 side filter is either a plain set of filtering matter (laminated) attached to  the valve box. - either a box (canister or cartridge) with a front filter, a highly efficient filtering device inside the cartridge which fixes the particulates, and  an exit way, screwed to the valve box. gasmask type filters (full face industrial or military) are fit with  a sealed cartridge, with a tiny front opening, and a screwing part bacwards. (all this is in my pics to be uploaded)
The filtering device in side or front cartridges is far more important (in quantity of filtering matter) and far more protected to exposition from contaminants - and moisture from exhalation - than a disposable cup mask. Not speaking of the wide range of professional filters, up to big cartridges > 1 liter.
So you see why such filters can last for hours or even days.

A good NBC mask, military issue.  About $300 anywhere.   there's an outfit called "brigadequartermaster" if you want to order them online, but hey, time is of the essence, so just hit your local military surplus shops until you find something appropo.

Be sure to pick up as many cartridges as you can get.
