Fireflies offering Facemasks and N95 Respirators

This is a really nice offer, especially considering how they are impossible to get from local and online stores. Thanks for the efforts!

do u have pics of the masks what to look for ??

Long story short:

I read about a study somewhere, that human body “has hard time” pushing fluids & viruses to as small particles as aerosols while sneezing.
Aerosols stay airborne for long but small droplets fall down faster.

The point of the article was, like you said, that even a normal more coarse filtering of breathing air than N95 might also be a good idea for normal folks.
There was a mention also, that during SOME medical operations aerosols may occur but can´t remember the whole article & can´t find it again anymore :expressionless:

I’m just giving you guys a heads up. You can ask Fireflies or wait until he posts pictures on his website.

Any thread or post with the best of intentions is a welcome respite .

Thanks for the heads-up.

We need more positive news like this.

FF just told me they received the high quality FFP2 respirators from Russia. I looked up FFP2 and it is what’s required in France for COVID-19 and is in extreme shortage.

He also received some FDA certified KN95 respirators from China manufacturers, which he will compare their quality with the FFP2 prior to posting on his website. The approximate price is cheaper than what I seen online and if he can stock them in his US warehouse, we wouldn’t have to wait 1.5-2 months for them, which is the standard wait time right now. I will not post the price until he determines which one is high quality enough to sell.

Here are the spec comparisons of the different facemask/respirator ratings:

Also as explained in my previous posts, the US NIH and Chinese experts already confirmed the virus is airborne and can remain infectious in the air for at least 3 hours. This means US CDC’s recommendation for non health care professionals to not wear respiratory protection is BAD ADVICE as their reason is the virus is not airborne. Currently only countries with extreme shortage of facemasks/respirators are telling the public not to wear facemasks.

The good news is that any filtration is better than no filtration. Here is a test showing effectiveness of different material at filtering 0.02 micron particle sizes. This is much smaller than coronavirus that averages 0.125 micron. This shows even a cotton shirt wrapped around your face will significantly reduce the viral concentration you inhale.

What Are The Best Materials for Making DIY Masks?



The above images are results from two separate studies showing N95 respirators and Surgical Mask performs the same in preventing respiratory virus infections.


This article explores the question of whether wearing masks can stop the spread of the Coronavirus. It includes a study that shows adults taking care of children with flu at home reduces infection by 75% by wearing either surgical mask or N95.


This article compares the filtration effectiveness of different material at filtering 0.007 micron particles, which is MUCH SMALLER than coronavirus.


This test compares filtration effectiveness against virus sized particles (0.02 to 1 micron) of homemade mask, surgical mask, and N95 respirator.

Update from Fireflies after testing his samples:

He also said the Level 3 masks he has is good quality!

I’m curious how he tested them too! I didn’t think it would be possible to test without expensive professional equipment.

I ordered 50 pieces of the Level 2 masks, DHL shipping - no confirmation of the order. It's been about 1 1/2 days since placing it, PP transaction went through. Does anyone know if he really has these and will be shipping them? Anyone else order some?

I ordered 50 pieces of the level 3 kn95 masks with free shipping to the US on 3/28/20. I received the tracking number today via a paypal email. It only shows a tracking number created on the date of purchase but no further activity. From my previous 4 orders with Firelies this is the way that they do notifications. I personally use ALL-IN-ONE PACKAGE TRACKING | 17TRACK for tracking. Hope this helps.

Ahhh, ok. Did you order the Cooper KN95's, so qty 5 of the 10 pieces? Was thinking of that. We still don't have any masks and am getting concerned, specially in our area where the infection rate is quite high. We know an ER doctor in our local hospital and he said they have 350 COVID-19 patients in beds, 80 in ICU.

To be honest I’m not sure. The ones I ordered on 3/28 are no longer listed. I’m hoping that those are the ones that I will be getting. I have one just like them that I ordered off of eBay that I payed $11.00 for one and I very much like the fit compared to the loose fitting paper ones. Here is what I ordered from my account.

It is bad enough that the Chinese caused this problem by eating bats and having dirty markets, now they make the problem worse by doing their typical fakery !

Can any of the masks available on their site be used repeatedly? How many times? Which ones are disposable?

They all are disposable, they all can be reused. Disposables became reusable - we are making due with what we can do. Over here in NY, I see anything and everything being done.

Thank you for reaching out and the post. I ordered some Cooper KN95’s.

Hopefully they are quality.

I placed my order on 3/30. I also paid the extra for DHL. Status still just “paid” not shipped yet :confounded:

Got an answer from fireflies regarding my order today. He said they have been shipped but expect a 3-day delay due to the Qing Ming holiday. He is also away with family doing Qing Ming activities. I asked when he would post up a test video. He said he will when he returns.

I can confirm that - Jacky answered my email saying shipments are delayed until Apr. 6th because of the holiday.

The Chinese seem to be constantly on holiday …
