If you’re in an area with poor air quality levels, or if an infectious illness has been going around, wearing an N95 face mask is a great way to protect your lungs and overall health.
Why to choose N95 face mask
N95 face masks are a great choice for protecting your lungs from dry particles（颗粒） in the air, which could include dust, or biological viruses. You can wear one when there’s been a flu outbreak in your area, or if pollutants or a fire has made air quality poor. These masks are made of structured, lightweight foam and fit over your nose and mouth.
How to choose N95 face mask
Depending on the particular N95 mask you choose, available sizes range from extra small and small to medium and large. If possible, try on a couple of sizes before you purchase one. Make sure the mask feels right and doesn’t slip on your face.
Store your masks correctly

Giving a gift that will stand the test of time is always a challenge,but giving plants is one way to try.Whatever type of plant you choose,it’s sure to last longer than cut flowers1.
The most important thing to consider is where it will live.If your friend’s place is bright and sunny,a succulent(多肉植物)makes sense. 2.Succulents naturally grow in desert-like environments,while orchids(兰花)grow in damp forests.
3.It can help you understand what conditions it prefers.So,while picking out plant gifts,ask the salesperson for more information to ensure what you choose is a match for where it will end up.
Whatever plant you choose,make peace with the fact that it may or may not survive.After all,a house’s inside is pretty dissimilar to where that plant naturally grows.So we can all only do our best.4.If their leaves dry up,they’re not getting enough water.If they’re reaching their leaves toward the light,they may need more of it.So offer that advice to your friend,and then let it go.
If you have a plant-interested friend on your gift list,why not choose a plant which is easy to keep alive in his place and looks lovely?You don’t need to wrap it,as a simple bow is enough.5.It’s a way to ensure your gift gets a good start in life.
A.You can always put them inside a paper bag.
B.But you can consider giving a nice pot and bag of soil.
C.Knowing the natural history of a plant is equally important.
D.Even relatively experienced green thumbs sometimes lose
E.The key is to pay attention to plants-really look at them each day..
F.If you want to choose plants as gifts,the ideas below will help you on your way.
G.If your friend has a cool home with no direct sun,an orchid is probably a better choice.
