·Smart Filter Replacement Reminder & Easy OperationThis home air purifier for pet owners is easy to install and comes with a clear user manual. It includes a filter replacement reminder function: after 1140 hours of operation, the filter indicator light will turn on to notify you when it's time to replace the filter. Simply press and hold the button for 5 seconds to reset the reminder, making HEPA filter replacement effortless. We recommend replacing the filter every 3–5 months depending on your environment and frequency of use.

·Real-Time Air Quality Monitoring & Auto ModeThe display shows real-time air quality readings, supported by four color-coded ambient lights (blue, green, yellow, red) that visually indicate air conditions. In Auto Mode, the purifier automatically adjusts the fan speed based on detected air quality levels. When air quality declines, the indicator turns yellow/red and the fan speed increases automatically to keep your air consistently fresh.

·High-Efficiency H14 True HEPA Filtration for Large Rooms & Multi-Space UseThe Cobectal ZQA-8000A features an upgraded H14 True HEPA filter with 99.995% purification efficiency, effectively capturing larger particles. It is suitable for large rooms up to 2200 sq ft and can purify a 300 sq ft room in just 30 minutes. Ideal for use in the kitchen, living room, bedroom, dorm, office, classroom, nursery, RV, or apartment.

·5 Fan Speeds, 3 Timer Settings & Child LockThis home HEPA air purifier offers 5 adjustable fan speeds and 3 timer options (2/4/8 hours). Choose your preferred speed based on air quality—higher speeds purify faster. Use the timer when cooking, working, relaxing, sleeping, or away from home. The child lock function prevents accidental shutdown from unintended button presses.

·Sleep Mode, Aromatherapy Function & Enhanced ComfortIn Sleep Mode, the purifier operates at a near-silent 24 dB, allowing peaceful air purification without disturbing work, study, or sleep. The top of the unit includes an aromatherapy tray with an included essential oil pad—add 4–6 drops of your favorite oil to refresh the air while creating a more pleasant and healthy living environment.
