We expected the bigger machine to win. The real differences had little to do with size.
Most of us picture a nebulizer as a humming box on the table with a hose and a cord to the wall. We set one up next to PureBreathe, a mesh nebulizer that fits comfortably in one hand, and used both the way you would at home. Here is what stood out.
A traditional nebulizer uses a compressor to push air through tubing into a medication cup, and that air pump is where most of its bulk comes from. PureBreathe uses a fine vibrating mesh instead. Liquid passes through tiny openings in the mesh and becomes a fine mist directly. It is not a shrunken version of the old machine, it is a different method that simply needs less hardware.

Our first instinct was that something this small must be leaving something out. Then we realised we were judging both devices purely by how big they looked. Without an air pump or hose, the whole unit fits comfortably in one hand, while the compressor needs its own spot on the table.

With a compressor, you are tied to the machine by tubing and the machine is tied to the wall by its cord. PureBreathe runs on its own rechargeable battery, so there is nothing to plug in while you use it. You can sit in the chair you actually want to sit in, not the one closest to the socket.

A compressor routine usually means positioning the machine, finding an outlet, connecting tubing and attaching the medication cup before you begin. With PureBreathe, you add sterile saline or the liquid medication prescribed for nebulizing, attach the mouthpiece or mask, and press the button to start your session. None of the old steps is hard on its own, but when you repeat the routine regularly, having fewer of them is what you notice most.

At home, a big compressor that never moves may not bother you. Away from home, you are packing the machine, its power cord, tubing, cup and accessories. PureBreathe slips into a handbag, work bag or carry-on and recharges over USB, which makes it easy to take to family visits, hotels, work or a road trip.

When we pressed the button, a fine mist began flowing from the handheld unit within seconds, with no compressor motor running beside it and no machine to warm up. The visible mist does not indicate how effective a treatment is. Results depend on the medication, the device and the instructions from your healthcare professional.
