10 Best Air Purifiers in the Philippines 2025 | Xiaomi, Levoit, and More

“Air purifier” is a term that applies to a wide variety of devices that aim to clean the air using different methods and technologies. Here are some types of air purifiers, how they work, and how they are useful in each household.

Air purifiers are only effective within their Clean Air Delivery Rate (CADR) range. While we usually think about our rooms in terms of area, the room's volume is actually more relevant when choosing an air purifier. Getting the right CADR ensures that your room's air is cleaned efficiently and that the purifier uses energy wisely.

Brands often provide a rated room size for their products, but understanding CADR allows you to make a more informed choice beyond marketing promises, as every room setup can differ. To calculate the necessary CADR for your room, follow these steps:

• Measure your room’s square footage - multiply the room’s length by its width to get the total square footage.
• Calculate the required CADR - take two-thirds of this number to determine the appropriate CADR for effective air purification.
  • Example: For a 300 sq. ft. room, you would need a CADR of approximately 200 (two-thirds of 300), assuming the room has standard 8-foot ceilings.

Leaving any appliance running for hours can make homeowners worry about their monthly electricity bill. Since you need your air purifier to run most of the time to keep the air in your room clean, it’s best to choose an energy-efficient model. Air purifiers usually consume less energy than other home appliances, with wattage typically ranging from 40 to 200 watts. For example, the Xiaomi 3H operates on only 38 watts.

To further minimize electricity costs, look for models with features like automated shutdown or timers to control usage. You can also use the Meralco Appliance Energy Calculator to estimate how much running an air purifier will add to your monthly bill. By selecting an energy-efficient purifier and utilizing its features, you can enjoy cleaner air without worrying too much about increased electricity costs.

Air purifiers can produce noticeable noise, which may disrupt your daily activities or sleep. To avoid this, many models feature "quiet operation," ensuring they won't interfere with work or rest, but still allow your air purifier to operate efficiently.

Look for air purifiers with a sound intensity rating of about 40 decibels or lower. This rating is comparable to the hum of a refrigerator, which is noticeable but not disruptive. It can seamlessly blend into usual background noises and won’t distract people from work, rest, or sleep.

Filipinos, whether working in an office or from home, may only need to run their air purifiers for a specific duration to effectively clean the air in the room. Many air purifiers now offer programmable settings, allowing you to automate when they operate based on your preferred schedule.

Here are some features that can help you customize and optimize your air purifier use:

• Air quality sensors - Monitor the room's air quality and indicate when it's time to run a cleaning cycle.
• Timers - Set the purifier to run in scheduled shifts and automatically turn off after the designated time.
• Remote control - Manage the air purifier settings from a distance for added convenience.
• Multiple fan speeds - Adjust the speed of air cleaning to suit different needs and preferences.
• Filter change indicators - Notify you when it's time to replace the filter, ensuring optimal performance.
• Night mode - Dims the display and operates on a quieter setting for undisturbed sleep.

Air purifiers can be a big investment, but they offer many health benefits. The advanced technology that makes these devices work well can still be expensive for most Filipino households. If you’ve decided to buy an air purifier, it’s best to choose a trusted brand. 

Well-known brands usually provide high-quality products that perform consistently, offer easy access to customer support, and include reasonable warranty options. Brands like Dyson, Sharp, and Levoit are worth considering because they help you save money in the long run by ensuring that your air purifier is efficient and lasts longer.
