Does it come with a filter? How often is it recommended to change the filter?
Answer by • Oct 05, 2025
The air purifier comes with a filter. The outer pre-filter should be cleaned every 2–4 weeks to increase efficiency and extend the life of your filter. Depending on how often you use the air purifier, the filter indicator should turn on at about 12 months. You can keep tabs on the remaining filter life by checking the filter life percentage in the app.
How loud is this?
Answer by • Jun 01, 2025
This purifier features unique QuietKEAP Technology which keeps the noise level as low as 24dB. That's similar to a whisper from about 5 feet away, rustling leaves, a quiet library, or light breathing.
