Why face masks can protect you from COVID-19?

We are no experts, this article explains why face masks can prevent COVID-19 based on general daily-life experiences, not based on rumors, rumorsare as dangerous as coronavirus, we just trust information from WHO and CDC. We will use the process of doing a grocery shopping as an example to explain how danger it can be and why wearing a face mask and doing other proper protections can stop you from getting coronavirus.
How COVID-19 spreads?

I guess everybody has already known how COVID-19 spreads, there are two major ways of how coronavirus spreads, they are:

  1. Through respiratory droplets produced when an infected person coughs, sneezes or talks.
  2. Spread from contact with contaminated surfaces or objects.

Here is an article from CDC about How COVID-19 Spreads.

When you are going to the grocery store, if you don't do any protections, then you are at a high risk of getting coronavirus. For examples: 1) You may use the shopping cart which was just used by someone who already has coronavirus but just not showing any symptoms yet, recent studies have suggested than coronavirus carriers can transmit it without symptoms. 2) Someone near you just coughed, then you might get coronavirus by inhaling some droplets. Check the "Is COVID-19 airborne?" section on this page Q&A on COVID-19 on WHO
How can we avoid getting infected by those two ways?

Since we have already known the ways of how coronavirus spreads, then how can we avoid getting infected by those two way?

How to protect yourself from inhaling silent carriers' droplets?
  1. Stay at home to avoid contact with others.
  2. Wear a cloth face covering / wear a face mask to reduce the chance of inhaling in droplets which were spreaded by silent carriers.
  3. Wear a cloth face covering / wear a face mask to stop spreading COVID-19 what if you are a silent carrier.
How to protect yourself from contact with contaminated objects?
  1. Stay at home to avoid touching any contaminated objects.
  2. WASH hands often. Washing your hands with soap and water or using alcohol-based hand rub kills viruses that may be on your hands.
WHO advice for public, that's a full list of advices given by WHO of how to prevent COVID-19,
Why wearing a face mask help stop COVID-19?

We think everyone should wear a face mask in public for three reasons.

  1. Wearing a face mask can stop silent carriers and people, who think thy are just getting a flu, from spreading virus wherever they go.
  2. Wearing a face mask can effectively stop you from inhaling in droplets which were spread by silent carriers.
  3. Wearing a face mask can stop you from touching your face subconsciously.

But wearing a face mask can help a lot, because face masks can capture most droplets, but it can't completely protect you, because viruses can transmit through some other ways, like transmit through the eyes.

Types of medial face masks.
  • The N95 is the USA standard
  • FFP2 is the EU standard. This includes the UK.
  • The KN95 is the China standard
  • The KF94 is the Korean standard
Different countries use different codes and numbers to name their respiratory face masks, they can all be used to prevent COVID-19, a face mask is way better than a homemade cloth face covering. Here are list of face masks we offer:
You can wear a surgery face mask when you go to the grocery store, wear a N95 mask when you go to a high risk areas, like enter a room to take care of someone who have COVID-19.
Why WHO still does't suggest people to wear a medical face mask?

That's due to the shortage of medical face masks in most countries, medical face masks are critical for keeping doctors and nurses from getting coronavirus. We 100% agree, if you have some medical face masks which meet your country's medical standards, then please donate them to your local hospital.

Why would experts saying wear a face mask could make things be worse at the beginning?

You can find quite a lot of those videos online. The virus is still relatively new, experts are also don't all about it, they made mistakes at the beginning. Some "experts" said wearing a face mask cloud increase the chance of touching your face, we totaly don't agree with that. I guess most people can wear a face mask properly without learning, because it's easy, and the first step is washing your hands, you will be totally fine even if you touched your face by accident. Check the "How to put on, use, take off and dispose of a mask?" section on this page Q&A on coronaviruses WHO.

Why buy face masks oversea is a good idea?
The shortage of medical face masks is common, don't stock face masks which meet your country's medical standards, if you have some, donate them to hospital. But buying face masks from countries which are not short of face masks is a good idea, because 1) You will get protected if you have face masks. 2) You don't need to buy from your local, which will help reduce the shortage.

1. When do you need to wear a Goggle?

If it's okay to do over protection?

Yes, if that's not a waist of medic important medical equipments, because doing over protection can really reduce the chance of getting affected, that's good thing from every aspect. Some people may laugh at you, just ignore them, you are doing every well of protecting you from COVID-19, if everyone can do that well, then the coronavirus outbreak will soon be gone.

If you wear a N95 face mask or a FFP2 face mask to the grocery store, that's totally wrong, you should donate medical face masks to your local hospital.
