How does the filter monitor its own lifespan?

The filter features RealTrack Technology, an intelligent monitoring system that calculates the remaining filter lifetime based on fan speed, usage time, and pollution levels. This enables accurate alerts for when a replacement is needed, ensuring optimal air purification performance without guesswork.

What types of pollutants does the filtration system capture?

The filter employs a 7-stage filtration system featuring HEPASilent technology, which captures at least 99.97% of tiny airborne pollutants down to 0.1 microns, including dust, pollen, pet dander, and other allergens. Additionally, OdorFence Technology effectively captures and breaks down common household odor gases for fresher indoor air.

Is the filter easy to replace?

Yes, the filter is designed for hassle-free replacement with an easy-to-install design. It ensures convenient maintenance, helping you keep your air purifier running efficiently without complicated procedures.

How long does the filter last?

This filter is crafted with durable materials that offer double the filter lifetime compared to standard filters. Longevity can vary based on usage and environmental conditions, but the smart monitoring system provides precise remaining lifetime information.

How can I check if this filter is compatible with my air purifier?

To confirm compatibility, you can unlock your phone and tap and hold it near the sticker on the air purifier's cage. This action automatically directs you to the compatible filter model, ensuring precise and hassle-free identification.
