Even if you're not going out, your home is still probably full of harmful gases thus you can't get fresh and clean air at home? After all, air is our necessity. All of us would like to breathe the cleanest air whether we go out or at home. Fortunately, many air purifiers can purify polluted air for your home. Now, the introduction of ultra-light air purifiers has been launched to make users no longer fear harmful air anytime and anywhere. Here are some tips on buying air purifiers and the best 10  air purifiers in 2021!

All about the filter

When buying an air purifier, the most important thing is its filter. In fact, different types of air purifiers on the market have various solutions of filtering air pollutants, so firstly we have to understand the features of various filters before the purchase.

• HEPA filter: This filter is the most common one in the air purifier. It is made of fiber and able to filter 99.7% of PM0.3 particles in the air. However, it should be noted that most HEPA filters cannot be reused and odors cannot be eliminated.
• Silver ion: It is a very effective antibacterial substance. It has been widely used in different places for antibacterial purposes, but it has only recently appeared in air purifiers.
• Activated carbon filter: The principle is to eliminate odor and volatile organic compounds through activated carbon, but it should be noted that its carbon can filter dust and other pollutants. The period of usage is about 3-6 months. When its essence is saturated, it will lose its effectiveness, and then it needs to be replaced.
• Static type: It can isolate all bacteria and viruses at the same time, and can effectively remove the particles of oil smoke and second-hand smoke in the air, and has the function of deodorization. However, if you want to be effective for a long time, you need to wash the components frequently, otherwise you may have the opportunity to fail to function.
• Negative ions: Chemical reaction turns into general water and carbon dioxide, so that the zero floating particles in the air are charged. When attracted to each other, they will fall to the ground and become dust. However, its effective range is not large, generally it can only reach tens of square feet, and it will generate a certain amount of "ozone", so the space used must be sufficient for circulation.
• Ozone: It can be used for sterilization, but it is only suitable for water treatment. Since oxygen is not stable, it will cause damage to the lungs when inhaled too much, so it is better not to use it.
• Photocatalyst: Refers to the use of ultraviolet light to decompose organic matter. However, its decomposition rate is slow, unless the air passes long enough, otherwise it will not be able to decompose bacteria in the air.

Dimensions

Many manufacturers will use the air purifier's usable room area (or suitable room area) to express its purification ability. If it is only used in a small room, a mini desktop air purifier is good enough; and if it is used in the sitting room, you can choose a larger floor-mounted air purifier. In addition, in recent years, more manufacturers have launched portable ultra-light air purifiers, which are smaller than the palm of the hand, and users can wear them as a pendant to go out, allowing users to breathe the freshest air anytime or anywhere.

Features

In order to make the user more convenient to use, the air purifiers on the market have different functions. Common functions are:

• Sleep mode: Even when used during sleep, the air freshener can be turned on with a small amount of air without a large operation sound, which does not affect the user's sleep.
• Wi-Fi function: Users can download related mobile phone applications to check the filter life of the air purifier, and the filter can be replaced when the filter life is approaching. In addition, there are applications that can be used as remote controllers for air purifiers, making your operation more convenient.
• Automatically sense the air quality: In the automatic mode, the air purifier will automatically start the fast cleaning function. The user can even confirm the air quality status at that time with the mobile application.
• Air quality display: In order to make it easier for users to know the air quality at that time, some air purifiers are equipped with indicator lights, which use different colors of lights to indicate the ambient air quality.
