[防疫資訊] 3M報告指出，一段外科口罩未能有效隔絕SARS

不過呢堆n95係咪都要做fit test

知唔知有咩途徑可以做呀?

用P95代N95有冇用？

講咁多野，又係黎呃飯食
sars病毒的大小只有0.08微米
口罩無論n幾多，都係用0.3微米做標準計過濾率
假如唔計防飛沫，只計過濾係空氣懸浮的病毒
無論外科口罩定你啲n99口罩都做唔到

sor我自膠左
唔記得set username
而家ok喇

得, 仲勁tim
不過要配岩filter

//第一種係美國NIOSH Standard。
NIOSH分別有3個系列N系(非隔油)、R系(隔油)、P系(防油)；根據過濾度，每個系列皆分有3個等級95、99、100。大家經常聽到既N95就係用於非隔油可過濾95%空氣粒子既面罩。

第二種評級標準係歐盟EN149 Standard。
歐盟分級比效簡單，分為FFP1、FFP2、FFP3，佢地分別可阻隔80%, 94%, 99%。所以FFP2係相等於美國N95，FFP3就相等於N99同N100//

唔得

sars入飛沬傳染，唔係airborne。手術口罩防到飛沬，ok㗎。

咪9up害人啦
How SARS is spread
SARS is an airborne virus, which means it's spread in a similar way to colds and flu.

The SARS virus is spread in small droplets of saliva coughed or sneezed into the air by an infected person. If someone else breathes in the droplets, they can become infected.

SARS can also be spread indirectly if an infected person touches surfaces such as door handles with unwashed hands. Someone who touches the same surface may also become infected.

The SARS virus may also be spread through an infected person's poo. For example, if they do not wash their hands properly after going to the toilet, they may pass the infection on to others.

Evidence from the SARS pandemic of 2002 to 2003 showed people living with or caring for someone with a known SARS infection were most at risk of developing the infection themselves.

2020年喇香港人
仲未識睇Source同Fact Check?

請google飛沬傳染 vs 空氣傳染。你要做生意你嘅事，不過買口罩可以喺amazon買，根本唔洗揾樓主代購。

Particulate Respirators
• Filter particles from the air when properly fitted, helping reduce the number of particles or germs the wearer breathes in.
• Are secured tightly to the face, with 2 head straps and a nose adjustable clip over the nose to allow for a more custom fit.

Surgical Masks
• Are cleared by the FDA for use as a surgical mask and are NOT designed to protect your lungs from airborne hazards like PM 2.5.
• Are typically donned for a specific procedure (eg surgery by a surgeon) and disposed of afterward.
• Help prevent large particles expelled by the wearer, such as spit or mucous, from entering the environment. If the
wearer coughs or sneezes, the surgical mask will help collect the
larger particles expelled.
• Usually do not fit tightly to the face as there might be gaps around the edges.

簡單講外科口罩同呼吸器(N95/99/100, FFP2/3)最大不同之處係
外科口罩: 防止Practical病毒由戴者身上散播
呼吸器:防止Practical病毒由外界吸入戴者肺入面

所以，有病就帶外科口罩，冇病唔想中招就帶呼吸器

完。

有冇人已經買咗 3M versaflo 備用

係嫁
冇人迫你買
我而家又唔係好似藥房狗咁開天價仲要亂sell野
我搵埋資料同報告比大家
買唔買，買邊款自己考慮

不過amazon收錢果個係美國佬/中國人
呢度係自己人
又話搞黃色經濟圈
外國手足唔係手足呀?

暫時都仲未有定論指沙士係經空氣傳播定飛沫傳播
如果n95 同外科口罩比 一定係n95 安全啲
但係戴個幾鐘就要除亦都係n95 嘅缺點

空氣傳播定飛沫傳播<----英國NHS答案both
但係戴個幾鐘就要除亦都係n95 嘅缺點<---所以有新型號設有valve抖氣

屌on99
有利益輸送就話自己係手足
無限上綱

收幾多手續費？

情感勒索

係外國搞活動面對既風險唔會比香港低
中國大使館動用全球資源去搞香港人
前幾日我地先有個手足收到中國人既死亡恐嚇同埋比人起底放上we7
我地而家都諗緊點幫佢好

黃色經濟圈唔係大家有共同理念既人建立一個市場咩?
呢一刻我地賣口罩因為香港人有需要
寧願比錢藍店大財團藥房狗
定係搵大家有共同理念既人幫手做代購


再者咩叫利益輸送? 我同共產黨有利益?定係同3M?

我地搵緊最平又可靠既貨源
聽日應該計到大概幾多錢

波蘭送去香港應該(7-10日左右)
好睇香港海關心情
