Dr Trust Signature Series Fingertip Pulse Oximeter (210)

₹1,199

Plus or minus 2 percent Arms sounds tight until you notice what it means: a displayed 94 percent could be 92.

Omron

₹1,899

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

Buy it if: Anyone monitoring a respiratory condition at home who wants a reading they can sanity-check.

Avoid it if: Anyone expecting hospital-grade certainty -- home oximeters are screening tools, not diagnostics.

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.
