In this section, Electrolux Philippines will share with you 3 tips to choose an air purifier, which are types of filters, room size, and noise level.
1. Types of filters
There are different technologies that air purifiers work on to effectively clean the air. Choose the product with suitable filters you want:
Pre-filter eliminates large particles like pet hair before the next stage of filtration. People having pets at home should choose air purifiers with strong pre-filter to get rid of pet hair.
HEPA (High Efficiency Particulate Air) filter is used to remove 99.97% of particles sized 0.2 microns or larger from the air. They are relatively effective against dust, pollen, mold, and dander.
People suffer from asthma or allergy should opt for air purifiers with HEPA filter. Note that some filters may not be certified to meet the requirements of a true HEPA filter, so research carefully before purchasing.
Activated carbon filters help in absorbing odors and gases, thus eliminate smoke, chemicals, food smell, and fumes. Activated carbon filters can quickly capture volatile organic compounds (VOCs), which is a compound released from burning fuel or release from household products. These gaseous pollutants can be harmful to everyone, especially if you have asthma or chemical sensitivity.
Antibacterial and germicidal filters eliminate harmful bacteria and germs.
2. Size of your room
The size of your room matters a lot when it comes to purchasing an air purifier. You need to make sure that the product is big enough to effectively purify the air in your room. For better performance, we recommend buying an air purifier that can operate in a space that is 20-40% larger than your room.
Also, the larger your room is, the higher CADR rating of the purifier you need. So what is CADR rating and why it matters when choosing an air purifier? CADR stands for Clean Air Delivery Rate that tells a consumer how efficient air purifiers are at removing a certain contaminant from the indoors. The three pollutants that are measured are pollen, smoke and dust.
The CADR rating reflects the volume of air in CFM (cubic feet per minute) that is cleaned of particles of certain sizes.
Typically, the larger the room, the larger the CADR rate you want. Manufacturers usually list the recommended CADR and room size on the guidelines, so read carefully when you buy a purifier.
This is the suggested CADR rate for different room sizes:
| Room Area (square meter) |
Minimum CADR (cubic meter per Hour) |
| 25 |
200 |
| 38 |
300 |
| 51 |
400 |
| 60 |
472 |
| 88 |
688 |
3. Noise level
