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.

## 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.
