Is the Therapy Air iOn White worth $150?

Only if you want a cordless, ozone-free ionic purifier for a desk or small room. At $150 from a single seller, it costs more than many HEPA purifiers that clean more air.

Does it have a HEPA filter?

No. It uses ionic filtration with a permanent washable filter, so there are no replacement filters to buy.

Does it produce ozone?

No. The listing states it is ozone-free, which matters because some older ionic purifiers emit ozone as a byproduct.

How long does the battery last?

The specs give a 3.7V lithium-ion battery but no runtime figure. Expect short runs between charges given the small battery and 1A draw.

What comes in the box?

The listing does not detail box contents. Expect the purifier itself and a charging cable; confirm with the seller before buying.

Is it good for a bedroom?

It is portable and quiet by design, but ionic units move little air. It suits a nightstand, not a full bedroom with allergies.

Our take on the Therapy Air iOn White

The Therapy Air iOn White is a small portable ionic air purifier that runs on a 3.7V lithium-ion battery and needs no HEPA filter. It uses a permanent, washable filter and generates no ozone, and it is certified CE, EAC, FCC and KC. It is a niche device: ionic units like this move little air and suit desks or small rooms rather than whole-home cleaning. Its best new price is $150 at eBay as of November 6, 2026, and only one store lists it new, so there is no meaningful price history to compare against.
