How long is the air purifier suitable for?

With the deterioration of air quality, people are becoming more and more dependent on air purifiers. Is it appropriate to keep the air purifier on? How long should the air purifier be on? Next, let’s take a look at the proper start-up time of the air purifier.

How long the air purifier needs to be turned on is actually determined by the air quality in the room. The worse the air quality, the longer it takes to turn on. On the contrary, the better the air quality, the longer it will take to keep it on.

When the weather quality is good or excellent, or when it is raining, it is recommended not to turn on the air purifier, because the dust and suspended solids will drop on a rainy day.

In the case of poor air quality, the start-up time is also related to the performance of the product and the size of the room. Generally, the working time of a general air purifier is four to eight hours to achieve a good purification effect. If the room space is larger If so, you can extend the time as needed.

When using the air purifier, it is recommended to close the doors and windows and to be more than 50 cm away from other household appliances and more than 50 cm away from the wall. If the air purifier is used with an active oxygen function, people cannot wait while the active oxygen function is on. Inside, because active oxygen will cause secondary pollution.

Another trick is that if the indoor air conditioner is turned on, you can place the air purifier on the opposite side of the air conditioner so that effective air circulation can be formed.

It should be noted that the electrostatic or plasma discharge purifier will produce a small amount of ozone during use. The long-term operation will cause the indoor ozone concentration to exceed the standard, so such purifiers are not recommended for continuous use. Whether it produces ozone or not can be identified by checking whether there is any peculiar smell at the air outlet after opening it for a period of time.

It is recommended to open more windows for ventilation in newly renovated houses because decoration pollutants such as formaldehyde are continuously released, and the emission will decrease with the passage of time, and the effect of opening windows to disperse formaldehyde on windy days is far greater Because of the CADR value of the air purifier, it is the best way to open windows for ventilation in the initial stage of newly renovated houses.

Will a small air purifier be effective in a large room?

It depends on how small the air purifier is and how big the room is. There are only two factors that affect the purification efficiency, one is the performance and thickness of the filter, and the other is the air volume.

The core indicator of an air purifier is the air volume and an air purifier with a certain air volume has a limited purification area. Here I don’t recommend just staring at the applicable area. The applicable area of many air purifiers is exaggerated. The air volume of a domestic air purifier is only 150m³/H, but the applicable area is 60 square meters, which is more than doubled.

So when choosing, be sure to check the air volume of that air purifier. Internationally, indoor air is required to be updated five times within an hour to meet the requirements of clean air. In this way, the applicable area of the air purifier can be calculated from the air volume. For example, the indoor height of a certain floor is 2.5 meters, and the applicable area = air volume/(5*2.5). Let me use my own olive green air purifier G2 to calculate it. 

The air volume is 290m³/H, so the applicable area is 290/(5*2.5)=23 square meters. When you buy on e-commerce platforms such as Amazon.com, you can first look at the air volume of the product, and then calculate the result yourself according to this formula, and then compare it with the applicable area advertised by the manufacturer, and you will know that the manufacturer has There is no exaggerated publicity.

How to choose an air purifier for your home bedroom

1. Make clear two purchase goals before purchasing

Two shopping goals should be clarified before purchasing. 

One is to determine what the main source of pollution in the home is, is it pollen, dust, PM2.5, PM0.3, smoke, and other physical pollutants? Or formaldehyde, benzene, toluene, xylene, and Chemical pollutants such as VOC? Or biological pollutants such as bacteria, viruses, molds, fungi, insects, and mites? 

The second is to clarify the area of the room where the air purifier is used, and then select the air purifier with the corresponding function according to the main pollution source; according to the area of the room Choose an air purifier that matches the cleanliness of the air.

2. Technical guides that need to be referred to in the purchase

  1. Purification technology
  2. Filter grade
  3. The amount of clean air
  4. Purification efficiency
  5. Real-time display of PM2.5 value
  6. Body structure
  7. Safety-secondary pollution
  8. Noise problem
  9. Power consumption problem

3. Use issues considered when purchasing

In addition to technical indicators, when purchasing an air purifier, you should also consider the problems you will encounter during use. First of all, you must see whether the design is humane and the operation is simple and convenient. Some people buy an air purifier and give it to their parents. I Will not use it, so whether the design of the air purifier is humane is also a factor that should be considered when buying. Some high-end air purifiers have a visual screen, and you can directly see the value of PM2.5, which is simple and convenient, and there is a child lock. The design prevents children from improper operation and is very user-friendly. Secondly, we must consider the issue of filter replacement and after-sales service.

4. Comprehensive consideration of the purchase

After considering the above three aspects, the purchase of an air purifier should also be considered from a comprehensive perspective, such as whether the manufacturer is a manufacturer specializing in the production of air purifiers, paying attention to distinguishing OEM manufacturers; whether it is in the real environment Really effective; whether it is safe and without secondary pollution. In addition, factors such as cost-effectiveness, reputation, brand strength, and service also need to be considered.

I hope can help you. thanks.

  • Check the noise level (listed in decibels) in the product specifications. Depending on where you use the air purifier, quieter equipment may be required.
  • Calculate the daily maintenance and electricity costs of the air purifier so that you can budget beyond the budget of the first purchase.
  • Unless money is not an issue, skip bonus features, such as application integration.

How to choose an air purifier for different room sizes?

The current national standard requires that all products must be marked with "clean air volume". Clean air volume=2.3×room volume/time. In other words, an air purifier with a clean air volume of 100 can only be used in a room with a volume of 42 cubic meters if it wants to purify 90% of the inhalable particulate matter within an hour. 

Assuming that the height of the room is 3 meters, the usable area is 14 square meters. However, there are also many products that directly indicate the coverage area. Since the purifier is easy to move in each room, you only need to choose the product that meets the largest room area in your home.

1. The room area is less than 30 square meters. Generally speaking, for air purifiers less than 30 square meters, you should choose an air purifier with a purification air volume of about 150 cubic meters per hour. Such a purification air volume can already achieve a better purification effect in terms of the area of the room! In the face of such harsh air, it feels like a luxury to be able to breathe. So the air purifier is used quickly, what about the Hoover air purifier in the United States, now I will share my experience with you.

2. The room area is between 30-50 square meters. If the room area is 30-50 square meters, you should choose an air purifier with a purifying air volume between 250-400 when purchasing, and the air volume is also 300-420 cubic meters. Between meters per hour, it is suitable for 30-50 square meters of living room, study, bedroom, or office.

3. The room area is between 51-99 square meters. The room area of 51-99 square meters is larger, so you should choose an air purifier with a large enough air volume when purchasing. It is best if the purification air volume can be more than 400 cubic meters per hour.

4. For rooms with a room area of more than 100 square meters, if you want a better purification effect, you can choose a commercial air purifier with a large purification area. This type of purifier has a larger purification area than a home office and has a good purification capacity. Stronger!
