Your home looks clean.
But have you ever checked the air?
Cooking dinner. Closing a bedroom door. Cleaning the house. Turning on a purifier. Every one of these changes the air around you. Most people never see it happen. This little screen does.
What It Watches
- Fine dust (PM1.0, PM2.5, PM10): Tiny particles from cooking, smoke, or dust.
- CO2: Tells you when a closed room needs fresh air.
- TVOC: Picks up sprays, fumes, and new furniture changing the air.
- HCHO (formaldehyde): A gas that can come from new furniture, paint, or building materials.
- Temperature & humidity: Tells you if a room feels too hot, cold, dry, or damp.
Eight readings. One simple question: does anything in this room need your attention?
Already Own A Purifier?
Here's the part most people never think to check. Turn on your purifier and watch this screen. If the number drops, it's working. If it doesn't move, now you know that too.
Check It From Anywhere
Connect it to your Wi-Fi and check any room from your phone, even when you're not home.
