Smart Air Purifier “Nimbus A1” — Features, Setup & Warranty

Product Page
Nimbus A1
Section
Features, Setup & Warranty

Nimbus A1 is a compact, ozone-free air purifier designed for apartments and small offices up to 28 m². To indoor air quality in mixed-occupancy spaces, the unit combines a HEPA 13 cartridge with a deep-bed carbon layer that targets smoke, VOCs, and cooking odors. A laser sensor tracks PM2.5 in real time; when Auto mode is enabled, the fan adjusts to meet target thresholds while maintaining a nighttime sound level of 22 dB. The top grille lifts for tool-free filter replacement, and a color ring signals remaining life. Place the purifier at least 20 cm from walls and keep doors ajar to prevent pressure pockets. The companion app displays AQI history, lockout controls for childcare rooms, and an energy timer.

Last season, some customers installed the device in enclosed cabinets or used non-compatible third-party filters, which reduced airflow and bypassed seals. , the packaging now includes a quick-start diagram and a tamper-evident filter frame. Only Nimbus A-series cartridges fit the housing; off-brand inserts may void performance claims. For best results, run the unit continuously on Auto and ventilate kitchens during high-heat cooking. Register your product purchase to activate the three-year limited warranty and filtered-air credit program. Worn cartridges can be mailed back using the prepaid envelope for responsible recycling.

Service requests require a serial number and proof of purchase. Units that show liquid ingress, smoke damage from open flames, or evidence of altered firmware are not covered. For safety, unplug before cleaning; wipe the shell with a dry cloth—do not spray solvents into the grille.
