The noise level of air purifiers varies depending on the model and fan speed. Generally, higher fan speeds produce more noise, but many modern air purifiers are designed to operate quietly, especially on lower settings.
How often should I run my air purifier?
The frequency of running your air purifier depends on the air quality in your home and your specific needs. For constant air purification, some models are designed to run continuously. However, for occasional use or in areas with low pollution levels, you might only need to run the purifier during certain times, such as when cooking or after cleaning.
