How does an air purifier clean polluted air?
An air purifier only cleans the air in its coverage area. It gives good results only if you have a separate purifier for each room.
An air purifier works by continuously drawing in, cleaning and releasing air back into the room.
The CRDR shows how quickly the air is cleaned, with a higher CRDR being required for larger rooms.
When we enter a house, we think that no matter how much dust or smoke there is outside, the air in the house is clean. But the truth is that these days the air inside the house is as polluted as the air outside. Especially in big cities, where the air quality index is consistently bad.
In such a situation, most people want to buy an air purifier, but they are worried about how to identify a good quality air purifier. If you do not buy a good quality air purifier, the air will be polluted. Therefore, before buying an air purifier, it is important to fully understand its actual workings, essential features and common misconceptions.
What does an air purifier do?
Many people think that an air purifier only freshens the room. But an air purifier works in a continuous process of pulling air, cleaning it and releasing it back into the room. The fan inside the machine pulls in dirty air, dust, PM 2.5, pollen, pet dander, smoke, etc. from the room. Then various filters do their job.
The HEPA filter captures very fine particles. The activated carbon filter absorbs household odors, cooking odors and gases. The pre-filter extends the life of the HEPA by blocking large particles. Some machines also have an ionizer or hybrid system, which makes the air even better.
6 things to pay special attention to before buying an air purifier
1. The higher the CRDR, the better
CRDR 'clean air delivery rate' shows how quickly the machine cleans the air. A high CRDR is needed for a large room and a medium CRDR for a small room. If you choose the wrong CRDR, the air will never feel clean.
2. Understand the life of the filter and the cost of replacement
Many people only pay attention when buying a machine, but replacing the filter later costs a lot. An air purifier is not a one-time item, but an item that requires regular maintenance. Therefore, you should buy it only after understanding the life of the filter and the cost of replacement.
3. How much noise does it make?
Especially in winter, when the fan or AC is not running in the room, even the light sound of the purifier can be heard all night. Therefore, if the noise of the air purifier is too loud, sleep will be disturbed and the benefits will be reduced. Therefore, you should choose one with low noise.
4. Power consumption should be low
Air purifiers should be used for many hours a day. Therefore, it is beneficial to choose a machine that consumes less power.
5. Smart features are necessary
If you are tech-savvy, features like Wi-Fi, mobile apps, real-time AEQI monitoring are very convenient. They can also control the machine remotely.
6. Remove these myths from your mind right now
Myth 1: One purifier is enough for the entire house
This is completely wrong. An air purifier only cleans the air in its coverage area. Only having a separate purifier for each room gives good results.
Myth 2: HEPA filters also remove odors
HEPA only captures particles. Only activated carbon filters have the ability to clean odors and gases.
Myth 3: Purifiers are only needed in winter
The air is not only polluted in the winter, it can also be polluted in the summer. In big cities, the AQI is often bad in every month, so an air purifier is useful all year round.
Choosing an air purifier with these things in mind will provide you with truly clean and healthy air.
