Name: TruSens air purifier Z-2000
Price (RRP): $229/399/549
Manufacturer: Acco Brands TruSens

Air purification has become a hot category, and TruSens have a range of three portable purifiers to suit small, medium and larger rooms.

GadgetGuy put the TruSens Z-2000 (medium room) to the test. It is a solid contender for the perfect purifier at just $399.

ACCO Brands is behind TruSens. It is best known for stationery products like Artline, Derwent, Esselte, GBC, Kensington, Maped, Marbig, Quartet, Rapid, Rexel, Spirax, Stabilo, and Xstamper. What GadgetGuy’s knows is that ACCO Brands are all about quality at reasonable prices in highly competitive markets.


  • We spend more than 90% of time inside (unless you are an outdoor worker)
  • Hay fever and Asthma are products of 20th-century environmental changes
  • You need both HEPA and Carbon filters to trap everything (as against synthetic fabric filters that only trap particulate matter)
  • Particulate matter ten (lower is better) is the maximum you should accept and around 3 or less is ideal.
  • And CADR (clean air delivery rate), not airflow, is the only way to rate a purifier

TruSens comes in three models

  • Z-1000 for small rooms to 23m2 $229
  • Z-2000 for medium rooms to 35m2 $399
  • Z-3000 for larger rooms to 70m2 $549

Room size assumes a standard 2.4m ceiling height. TruSens does not quote a CAGR (rate per cubic metre) but states that air changes twice every hour. On that basis the Z-2000 that is a CADR of 168m3 ( 168,000 litres or 47lps) – impressive.

Each has a different sized Dupont filter unit comprising individually replaceable HEPA and actve carbon filters. They also have a replaceable UV bulb that helps to prevent the growth of odour-causing microbes on the surface of the filter — these last up to three years.

Trusens SensorPod

The Z-2000 and Z-3000 come with a separate TruSens SensorPod that can be placed up to 15 metres from the TruSens and monitors air quality in the room.

This is important to ensure that the whole room is purified – not just the air around the filter. It also enables the TruSens to display the 1 to 500-point Air Quality Index (AQI) scale from the Environmental Protection Agency (EPA). 


For example, here is the NSW AQI and you can search for each states AQI. During the test, the outside AQI was 49 in the ‘good green range’. The purifier bought that down to six!

Setup is simple – no app required.

  • TruSens Z-2000 and a two-pin standard power cord
  • SensorPod and a 9V/.5A plug charger

Place the filter pod up to 15m away and turn on both. Pair the SensorPod to the TruSens. Done.


Initially, for around 10 minutes, the TruSens was working overtime on Trubo (maximum fan speed) but gradually became whisper quiet as the AQI lowered.

It is best to leave it on 24/7 (Auto mode requires SensorPod). Our tests were in a 30m2 office and as soon as a door or windows opened the AQI indicator shot up to the 40s.


Our measurements were from 35dB (typical) to 70dB at Turbo speed.
