Qenza Air One Smart HEPA Air Purifier
Why indoor air still needs help
Rooms hold onto dust, cooking, and whatever the day brings in. Air One keeps working in the spaces where you actually spend time, without turning clean air into a science project.
What Air One is here to do
-
Capture
A HEPA filter sits in the path of air moving through Air One, so fine particles have somewhere to land. Measured capture results will be published when they exist.
-
Circulate
Air One is meant to keep air moving through the room, not only the air sitting against the unit.
-
Quiet nights
Leave it on while you sleep. The aim is a room that stays peaceful, not a machine you have to switch off.
Built for mid-to-large rooms
Air One is sized for the living room, the open bedroom, the place you actually sit. Placement guidance ships with the product. Coverage is not a guessed number.
Genuine filters, on your schedule
Replace the filter when it is due, not when an app nags you. The Genuine Filter 3-Pack is the refill made for Air One.
FAQ
Questions, briefly
What room is Air One for?
Air One is for one mid-to-large room you live in, such as a living room or a primary bedroom. It is not a whole-home system. Qenza has not published a square-foot rating or a CADR. Use the room you actually sit in, and follow the placement notes that ship with the unit.
Do you publish CADR or lab results?
No. Qenza does not publish CADR, ACH, or a lab certificate for Air One until those measurements exist. Product pages will not estimate them.
How do I replace the filter?
Air One uses a genuine Qenza filter. The refill is the Genuine Filter 3-Pack. Replace a filter on a schedule you set, or sooner if it looks loaded. There is no hour rating and no app countdown.
Where do you ship?
Free shipping on Air One is announced for the continental United States. The rate at checkout is the rate that applies. That announcement does not cover Alaska, Hawaii, or addresses outside the continental US.
Can I return Air One?
Ask from your order confirmation, or use the support email, for an unused Air One or an unopened Genuine Filter 3-Pack. The Returns page is where a numbered window belongs. This answer does not add one.
Is Air One a medical device?
No. Air One is a room air purifier for everyday indoor air. Qenza does not claim it treats, prevents, or cures any condition.
