Why Matching the Size of Air Purifier to the Room is Beneficial
Choosing the right-sized air purifier for your specific space is crucial to ensure optimal performance and maximum air purification benefits. Here are some key reasons why matching the size of the air purifier to the room is beneficial.
1. Efficient Air Cleaning
Air purifiers are designed to clean the air in a specific coverage area. When you choose an air purifier that matches the size of your room, you can be confident that it will efficiently and effectively clean the air within that space. A properly sized air purifier ensures that all the air in the room is properly circulated and filtered, eliminating airborne pollutants and improving indoor air quality.
2. Enhanced Filtration
Different air purifiers come with varying filtration capacities. Larger air purifiers often have more robust filtration systems, including multiple filters and higher airflow rates. By selecting an air purifier that is appropriately sized for your room, you can take advantage of these advanced filtration technologies. This allows the air purifier to capture a wider range of pollutants, such as dust, pet dander, pollen, mold spores, and volatile organic compounds (VOCs), providing cleaner and healthier air for you and your loved ones.
For those seeking specialized solutions, custom air care options are available, including custom filters for popular models like the Airmega Mighty and 200M, as well as the 350/450 series. These custom filtration options can be tailored to address specific air quality concerns in your environment, further enhancing the effectiveness of your air purification system.
3. Reduced Energy Consumption
Using an air purifier that matches the size of your room can help optimize energy consumption. An undersized air purifier may struggle to effectively clean the air in a larger space, leading to increased runtime and energy usage. On the other hand, an oversized air purifier in a smaller room may consume more energy than necessary. By selecting the right-sized air purifier, you can ensure efficient operation and minimize energy consumption, contributing to cost savings and environmental sustainability.
4. Noise Level Considerations
Air purifiers vary in terms of noise levels produced during operation. Larger air purifiers with higher airflow capacities may generate more noise compared to smaller models. When choosing an air purifier for a specific room, consider the noise level that is acceptable for that space. A properly sized air purifier will strike a balance between effective air cleaning and maintaining a comfortable noise level in your living or working environment.
A properly sized air purifier will strike a balance between effective air cleaning and maintaining a comfortable noise level in your living or working environment. Most Airmega models' lowest airflow mode operates at around 20db (as quiet as a whisper) for sensitive sleepers, to turbo mode on some models which can be as loud as 40 db (as loud as ordinary conversation or a refrigerator hum). You can literally hear the air being sucked in and purified in this case.
5. Aesthetics and Space Optimization
A well-sized air purifier can fit seamlessly into your room's layout and décor. Choosing a model that matches the room's size ensures that the air purifier doesn't dominate the space or appear too small and inconspicuous. Aesthetically pleasing air purifiers can enhance the overall ambiance of the room while still delivering the necessary air purification benefits. With the right-sized air purifier, you can breathe easier, promote well-being, and create a healthier environment in your chosen space.

5The coverage area of the air purifier is based on an area where the air cleaner can make two air changes per hour (ACPH). An air change per hour translates to how many times an air purifier can clean an area, assuming the height of a ceiling to be 8 ft, in one hour. Therefore ** means two air changes per hour means that the cleaner can clean the area once every 30 minutes and * means air changes per hour means that the air purifier can clean the area once every 60 minutes.
