Rank #8 in Best Air Quality Monitor 2026: Fewer Numbers, Better Sensors
Temtop Air Quality Detector, PM2.5 PM10 Laser Particle Monitor
Price and rating as shown on Amazon when we collected them. Both change.
The Temtop particle monitor does one job: PM2.5 and PM10, using a laser particle sensor the listing rates for up to 20,000 hours, displayed on a colour TFT screen with a histogram of recent readings. It is £67.99 with 4.4 stars from 153 ratings.
It is eighth because particles alone leave out the measurement most people actually need — CO2, which tells you when to ventilate — so it works best as a second monitor alongside one of the CO2 meters above. As a dedicated particle instrument at this price it has no competition on this page.
How those 153 ratings break down
An average hides its own shape. This is the spread behind the 4.4 stars.

Questions people ask
Does it measure CO2?
No. It measures PM2.5 and PM10 particles only, which is why it can do that job well at this price.
What can it detect?
Airborne particles: smoke, pollen, dust, traffic and wood smoke. It is the monitor to buy if particles are your concern.
Is the laser sensor reliable?
The listing rates the sensor for up to 20,000 hours and describes it as high precision. Unlike the multi-reading meters, particles are the only thing it measures.
Does it connect to a phone?
No. The screen and the four buttons are the interface, with a histogram rather than app history.
Who is it for?
Someone who already has a CO2 meter, or lives near traffic or a wood burner, and wants a dedicated particle reading.
How many ratings does it have?
153 at the time of collection, averaging 4.4 stars, with 70 per cent five-star and 4 per cent one-star.
