Indoplas BP105 blood pressure monitor review

At around ₱749 as of August 13, 2026, with a 22 to 34cm cuff, 74 readings of memory and irregular heartbeat detection. Start with the cuff, because it decides whether anything else matters.

Cuff size is the biggest source of error in home monitoring

Not the electronics. The cuff.

A cuff that is too small for the arm has to inflate to a higher pressure to compress the artery underneath, and the monitor reports that higher pressure as your blood pressure. The error runs in one direction and it can be substantial, enough to turn a normal reading into an apparently high one.

This cuff covers 22 to 34cm, which is the standard adult range and does not stretch to larger arms. So before ordering, take a tape measure to the midpoint of your upper arm, between shoulder and elbow, and measure the circumference.

If you are over 34cm you want a large-cuff model, and buying this one will produce readings that worry you for no reason.

Upper arm is the right format

Home monitors come as upper-arm and wrist units, and clinical guidance consistently prefers the upper arm.

Wrist monitors are sensitive to position: the wrist has to be held at exactly heart level, and a few centimetres out changes the reading. Arteries at the wrist are also smaller and less regularly placed. They exist because they are convenient, and convenience is the whole argument for them.

This is an upper-arm monitor, which is the format to buy.

The routine that makes readings mean something

More than half the value of a home monitor is in how you use it. All of this is free and most people skip it.

Sit for five minutes first, back supported, feet flat on the floor, legs uncrossed. Rest the arm on a table at heart level. Do not talk during the measurement, which raises readings measurably. Empty your bladder first, and avoid caffeine or smoking for half an hour before.

Then take two readings a minute apart and average them, at the same times each day, usually morning and evening.

A single reading in a random position after climbing the stairs is not information. A week of properly taken pairs is.

What the irregular heartbeat symbol is for

It means the monitor detected an uneven rhythm while measuring. That is worth mentioning to a doctor, particularly if it appears repeatedly, because atrial fibrillation is common, treatable and a significant stroke risk when missed.

It is not a diagnosis, and it can be triggered by moving, talking or shivering during the measurement. Repeat the reading sitting still before reading anything into it.

Why home monitoring is worth doing at all

Two reasons that a clinic visit cannot cover. White coat hypertension, where pressure rises at the doctor’s office and is normal at home, leads to overtreatment. Masked hypertension, the reverse, leads to no treatment at all. Only home readings distinguish them.

Keep the log, bring it to appointments, and do not adjust any medication on your own.

Who should buy the BP105

Buy this if your arm measures inside 22 to 34cm, you want an upper-arm monitor at a modest price, and you will use the routine above.

Skip it if your arm is larger, where the readings will be wrong in a way no feature fixes.
