Best Place to Position Temtop M10i Air Quality Monitor Malaysia
Meta Description: Learn where to position the Temtop M10i for representative PM2.5, formaldehyde and TVOC monitoring in homes and offices in Malaysia.
The position of an indoor air-quality monitor can significantly affect its readings.
A Temtop M10i placed directly beside an open window, air purifier or new cabinet may show different results from one positioned in the main occupied part of the room.
The Temtop M10i monitors:
PM2.5
HCHO (formaldehyde)
TVOC
AQI
Correct placement helps users obtain more consistent readings for screening, trend monitoring and before-and-after comparisons.
General Placement Recommendation
For general indoor monitoring, place the M10i:
At normal breathing height
On a stable surface
In a frequently occupied area
With its air inlets unobstructed
Away from direct sunlight
Away from direct air-conditioning airflow
Away from open windows and external doors
Away from immediate pollution sources
The monitor should represent the air in the occupied space rather than an unusual location.
Why Breathing Height Matters
A monitor placed on the floor, near the ceiling or inside a high cabinet may not represent the air people normally breathe.
Normal breathing height depends on the room and activity:
Seated office: desk or table height
Bedroom: suitable bedside height
Living room: table or shelf near the occupied zone
Standing workspace: higher representative position
Consistency is important. When comparing rooms, use approximately the same monitoring height.
Where to Position the M10i in a Living Room
A suitable living-room location is:
Near the occupied seating area
Away from the television’s heat exhaust
Away from balcony doors
Away from cooking smoke
Away from air-conditioner outlets
Away from incense or candles
Away from the purifier outlet
If the living room connects directly to the kitchen, note whether cooking is taking place because it can increase PM2.5 and TVOC.
Where to Position It in a Bedroom
In a bedroom, place the M10i:
On a stable bedside table or shelf
At breathing height
Away from the window
Away from direct air conditioning
Away from perfume and aerosol products
Away from the purifier outlet
Outside the reach of children
Do not cover the monitor or place it under bedding.
For overnight monitoring, keep it in the same position so historical trends remain comparable.
Where to Position It in an Office
For general office monitoring:
Select a representative occupied workspace
Avoid direct airflow from central air-conditioning outlets
Keep it away from printers during the initial general assessment
Avoid reception doors and loading entrances
Keep it away from cleaning-product storage
Position it where it will not be disturbed
One monitor may not represent a large open office, several departments or multiple floors.
Where to Position It After Renovation
For a general room reading after renovation, place the M10i away from:
Wet paint
Open adhesive containers
New cabinets
Chemical products
Renovation waste
Heavy dust
Direct airflow
This provides a reading that better represents the occupied area.
A separate targeted source check can be performed near a cabinet, flooring section or furnishing. Clearly record that the measurement was taken near the suspected source.
Should the M10i Be Placed Beside a Window?
Not for general indoor monitoring.
A monitor placed beside an open window may respond strongly to outdoor haze, traffic pollution or wind-driven air.
This location can be useful if the specific purpose is to investigate pollution entering through the window.
For normal room monitoring, position it farther inside the occupied area and document whether the window is open or closed.
Should It Be Placed Beside an Air Purifier?
No. Do not place the M10i directly beside the purifier’s clean-air outlet or air intake.
A monitor positioned in the clean-air stream may show lower PM2.5 than the rest of the room.
For a purifier comparison:
Position the M10i in the occupied area.
Keep it away from direct purifier airflow.
Record the initial PM2.5.
Operate the purifier.
Keep both devices in fixed positions.
Observe the trend over time.
This provides a more representative indication of how the room is changing.
Should It Be Placed Under an Air Conditioner?
Avoid direct airflow from an air-conditioning outlet.
Direct airflow can cause readings that mainly represent the supplied air rather than the overall room.
A better position is within the occupied zone but outside the direct air stream.
Also remember that not every air-conditioning system introduces outdoor fresh air or provides effective PM2.5 filtration.
Can It Be Placed Inside a Cabinet?
A reading inside a cabinet may be useful for investigating that enclosed space, but it should not be described as the general room reading.
Cabinet conditions may differ because of:
Limited ventilation
Close distance to materials
Smaller enclosed volume
Different temperature and humidity
Concentrated emissions
Record cabinet readings separately and compare them with a general room measurement.
How Far Should It Be From a Suspected Source?
There is no single distance suitable for every investigation.
The important distinction is between:
General room monitoring: Away from the immediate source
Targeted source investigation: Close to the material being checked
Record the location and distance whenever possible.
Without this information, results from different positions may be misinterpreted.
How Long Should the M10i Stabilise?
Allow sufficient time for the instrument to respond after:
Switching it on
Moving it between rooms
Opening a cabinet
Changing ventilation
Starting an air purifier
Introducing a new material
Avoid recording a result immediately after moving the monitor.
The required response and stabilisation practices should follow the manufacturer’s user instructions.
Should the Monitor Be Moved Between Rooms?
It can be used for room comparisons, but consistent methodology is necessary.
When moving the M10i:
Record the original room and time.
Move it to the new location.
Use approximately the same height.
Allow sufficient response time.
Record doors, windows and activities.
Use the same observation duration.
Avoid comparing readings taken under unrelated conditions.
For continuous historical monitoring, leaving the M10i in one selected room generally provides more consistent trend data.
Locations to Avoid
Avoid placing the M10i:
In direct sunlight
Outdoors permanently
In rain or high-moisture locations
Beside cooking appliances
Beside cigarette smoke
Beside incense or candles
Near aerosol sprays
Directly under air conditioning
At the air-purifier outlet
Inside a closed drawer
With blocked sensor openings
In areas where it can be knocked over
Protecting the instrument from contamination and unsuitable conditions supports more consistent operation.
Can One Position Represent the Whole Building?
No. One monitor represents conditions at its installed location.
Larger premises may require:
Multiple monitors
Measurements on different floors
Checks near entrances
Separate monitoring in renovated rooms
Portable room-to-room surveys
Professional IAQ assessment
The monitoring plan should reflect the building’s size, layout, ventilation and occupancy.
