1. How does an Air Purifier work?

An air purifier works on different technologies. But the functionality remains the same. It removes contaminants from the room and improves air quality. The purifier eliminates dust particles, smell, smoke, bacteria, and viruses. It traps the contaminants. It works in two ways. Inactive way, the purifier settles downs the dust particle or germs by releasing negative ion. Passively, it collects all the particles on the filter and keeps them. The user can replace the filters. The time of changing filters depend on the model of air purifier.

2. What is the functionality of an Air Purifier?

Automatic mode and Sensors: Sensors used in the air purifiers control speed. The sensor senses the number of pollutants in the air. It sets the fan speed and power to filter the air. The user can set the air purifier on automatic mode and it starts working itself.

Air Purifier timer: The air purifier can turn off and turn on by setting the timer. If the user is going away for a long time and wants to come back in clean air, the timer will help. You can switch the Air Purifier on and off with your mobile using an application.

Night Mode: When the night mode of the purifier actives, it switches on a dim light. In night mode, the purifier doesn’t produce any noise. It helps you to sleep peacefully in quiet and clean air.

Smart Air Purifier: Smart air purifiers use with the help of a smartphone. A mobile application guides the user about the functions of the purifier, air quality, and filtration level. The mobile phone can control the working of the device.


3. What size Air Purifier do you need?

There are many sizes of air purifiers with different ranges of coverage available in the market. Some common types in term of size are:

Table Air Purifiers: Table air purifiers are small. These air purifiers have less power and functionalities, as compared to the big air purifiers. They are kept on a desk or table. The price of table air purifiers is very affordable.

Tower Air Purifiers: Tower air purifiers are big and look like a cylinder. They can work in big spaces. These air purifiers include advanced features to clean air. Tower air purifiers come in different shapes.

Portable Air Purifiers: As the name suggests. these air purifiers can be moved easily. They are also available in medium and large sizes. These purifiers work effectively to clean the big spaces. They can also move as the portability feature is included.

Oscillating air purifiers: Oscillating air purifiers are fixed at a specific place and rotate to clean the air. They can used in both small and big spaces.

4. Choose between the different types of Air Purifiers

HEPA Technology: HEPA (High-Efficiency Particulate Air) is the most common technology use in air purifiers. It is an effective way to trap the polluted particles. HEPA filters can catch 99% of the dust particles from the air. It is a fiber type material that is high in quality. The fan pushes the air. When the air passes through it, the pollutant particles stuck in the filter. And the purified air flows from it. HEPA filters are the most convenient air purifiers to use in small space like a room. It can trap the dust particle and gas molecule. You only need to change the filter paper once a month.

Activated Carbon Air Purification Technology: The activated carbon technology is more powerful as compared to HEPA filtration. In this technology, process carbon uses. Carbon becomes porous after processing. It provides a large surface to absorb the impurities. It works on a simple phenomenon. The pollutants stuck in the pores of carbon, and the filtered air passed through it. In this way, the activated carbon works to clean air from toxic gases. The activated carbon filters act effectively for odors. It removes chemicals, bad smells, and fumes from the room. If you want to eliminate the dust and pollen particles, then you need to look for the model with HEPA filtration.

Ionic Air Purification Technology: The ionic air purification technology works differently from the casual air purifiers. It doesn’t absorb any pollutants. Instead of it, it eliminates the negative ions in the air. The polluted particles in the air carry a positive charge. The positive pollutants combine with the negative ions, they form strong bonds. When bonds form, the particles become heavy. Due to their heavy weight, they fall out of the air. Some models of ionic air purifiers contain electrostatic precipitators. These purifiers don’t absorb and dispose of the impurities. The chance might the air contaminate again after some time.

Ozone Air Purification Technology: Ozone air purification technology works like an ionic purifier. But in this technology, the ozone gas eliminates the device and kills the germs and contamination from the air. Some research states, it is inappropriate to clean the air with ozone. According to some researches, ozone purifiers work effectively to kill bacteria and viruses without causing side effects. The ozone air purifiers use in extreme cases of infections. It is not good to use these purifiers regularly. (Caution: The ozone air purifiers can cause asthma or lung issues. You should not use them in ordinary cases.)

Ultraviolet Air Purifiers Technology: The ultraviolet air purifiers work with ultraviolet rays. The idea to make this purifier inspire by hospitals. The ultraviolet rays use in hospitals to disinfect the operation theaters and wards. These rays kill all infected particles such as bacteria and viruses from the air. The ultraviolet rays break the bonds between particles. In this way, it kills the pollutants and germs. The rays eliminate from an electric bulb that needs to change after a year. This purifier effectively kills bacteria and viruses. It doesn’t work well to remove dust particles from the air.
The best air purifier contains all these technologies to clear the air.

5. What are your Requirements?

Before buying anything, you should know your needs. According to lab tests, air purifiers work well to clean the air in a room. Time and efficiency depend on the model of the device. If you are an asthma patient or have dust allergy, the air purifier will help you a lot to remove all pollutants and toxic materials. If you are not a patient, then a simple air purifier can work well for you.

6. Check the noise level of the Air Purifier

The purifiers are those who work quietly without making any noise. Most purifiers do not produce sound. But the purifiers with advanced technologies may produce some sound. Sometimes the purifier start making noise during working times. In this case, you need to check your filter and fan.

7. What is your budget?

The price of air purifier depends on technology use in it. If the purifier equipped with simple HEPA filtration or Activated carbon filter, it doesn’t cost much. The purifiers equipped with advanced technologies(iconic, ozone, ultraviolet) are expensive. The air purifiers having all the functionalities are high in cost.

8. Is an Air Purifier worth buying?

Many people feel confused about either buying an air purifier worth it or not. An air purifier is always worth buying. It provides you a clean and germ-free air to breathe. It helps asthmatic patients, dust allergic people, and children.

9. Best place to keep Air Purifier

The air purifier works for a room. The best place to keep the purifiers is bedrooms. But if you want to clean the air of the living room, you can also place it there. Some people think portable air purifiers can be used for this purpose. It is not the right way to use the purifier. You need to invest in separate purifiers for different rooms.

10. What maintenance is involved?

The maintenance of purifiers applies by replacing filters. It depends on the type and model of the purifier. HEPA filters can last for one year to five years. The activated carbon filter air purifier lasts for 6 months. The ozone, iconic and ultraviolet purifiers need more maintenance as compared to other purifiers. If you frequently use the purifier, then you may need to change filters early.
