Omron NE-C801 Compressor Nebulizer for Respiratory Therapy

₹1,899

Particle size is the specification that decides whether a nebuliser works, and it is the one cheap units never print.

Vissco

₹1,299

The hinges are the whole difference, and the reason to pay three times a plain knee cap.

Buy it if: Anyone managing asthma or COPD at home who needs medication to reach the lower airway.

Avoid it if: Anyone needing continuous use -- the compressor must rest 40 minutes after 20.

Buy it if: Anyone with ligament instability or recovering from a knee injury who needs lateral support.

Avoid it if: Anyone with simple arthritic ache -- a plain elastic knee cap costs a third as much and does the same thing.
