The answers below are the same facts as the homepage. They do not add a CADR rating, a lab certificate, or a medical claim.
FAQ
Questions
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.
