The Smartmi E1 filter features a highly effective filtration capacity, capable of filtering particles at a rate of up to 150 m³/h while distributing 2500 liters of clean air per minute. The filter consists of three layers, all contributing to the air purifier E1's ability to cleanse the air of particles such as pollen, pet hair, dust mites, smoke, and other airborne pollutants, as well as reducing allergens and unpleasant odors.

The inner layer of the filter is an activated carbon layer that adsorbs formaldehyde, volatile organic compounds, odors, and other gaseous impurities. The second layer promotes highly effective filtration of particulate contaminants. The outer layer serves as a decorative main filter that captures dirt and hair, thus extending the lifespan of the filter. This outer layer can be chosen in various colors and patterns, allowing you to select either a clean and elegant fabric that fits seamlessly into any home or a vibrant fabric that adds extra flair to your living environment.

The replacement interval is approximately 6-12 months.
