Yes. In addition, the SensorPod of the Z-2500 and Z-3500 has an all new design and features additional sensing capabilities. It can measure three sizes of particulate matter (PM1.0, PM2.5, PM10) as well as VOCs, and calculates the overall air quality using a proprietary algorithm that is reactive to genuine increases in pollutants without overreacting to someone entering the room or settling into the couch.

What size room does each TruSens Air Purifier cover? Chevron Icon
  • Z-1000: We recommend using the TruSens Z-1000 in a small room, up to 250 sq. ft.
  • Z-2000/Z-2500: We recommend using the TruSens Z-2000/Z-2500 in a small or medium room, up to 375 sq. ft.
  • Z-3000/Z-3500: We recommend using the TruSens Z-3000/Z-3500 for any room size up to 750 sq. ft.
Does the unit come with a filter included? Chevron Icon
  • Z-1000: Yes, the TruSens Z-1000 comes with a Carbon Prefilter and a HEPA Type filter. It also comes with a UV-C emits light that reduces growth of germs and bacteria that can get trapped in the filter.
  • Z-2000/Z-2500: Yes, the TruSens Z-2000/Z-2500 comes with a washable Prefilter, Carbon Layer and HEPA type filter.It also comes with a UV-C emits light that reduces growth of germs and bacteria that can get trapped in the filter.
  • Z-3000/Z-3500: Yes, the TruSens Z-3000/Z-3500 comes with a washable Prefilter, Carbon Layer and True HEPA filter. It also comes with a UV-C emits light that reduces growth of germs and bacteria that can get trapped in the filter.
Is the Standard Filter included washable? Chevron Icon

The Prefilter on the Z-2000/Z-2500 and Z-3000/Z-3500 units is washable. Gently rinse the Prefilter under running water and allow to dry before reinstalling on the filter drum. Carbon and HEPA filters are not washable and should be replaced, as needed. The purifier is equipped with replacement indicators that will notify you when it is time to replace the Carbon or HEPA filter. Plan on replacing the Carbon filter every 3-4 months and the HEPA filter every 12-15 months.

How often do I need to replace the filter? Chevron Icon

TruSens Air Purifiers is equipped with replacement indicators that will notify you when it is time to replace the Carbon, HEPA filter, or the UV-C light. Plan on replacing the Carbon every 3-4 months, HEPA filter every 12-15 months, and the UV-C light every 1-3 years.

  • Z-2000/Z-2500/Z-3000/Z-3500: Visually inspect the Prefilter every month and wash as needed. We also recommend washing the Prefilter every time you replace the filter or the UV-C light.
How loud is the TruSens air purifier? Is there a quiet mode? Chevron Icon
  • Z-1000: The TruSens Z-1000 operates quietly, with levels ranging between 39-65 dB, dependent on the fan speed setting.

Does the TruSens Z-1000 purifier have a SensorPod? Chevron Icon

The TruSens Z-1000 does not have a SensorPod. It features 360-degree DuPont filtration which allows for the collection of pollutants from around the room. It also has our proprietary PureDirect dual airflow that moves cleaner air more efficiently throughout the room.

Will multiple SensorPods™ in a home or building interfere with one another? Chevron Icon

TruSens Air Purifiers are factory paired with SensorPod™ and designed to not interfere with one another.

Can you have multiple TruSens Air Purifiers in your home? Chevron Icon

For best results we recommend that you have an air purifier in rooms that are occupied. We made moving the air purifier easy with the integrated carry handle. However, it may be more convenient to have multiple air purifiers around your home.

Should the SensorPod™ and air purifier be in the same room? Chevron Icon

Yes. The SensorPod™ measures pollutants in a room and the air purifier responds accordingly. For this system to work as intended you should place the air purifier and SensorPod in the same room. Also, please make sure that the air purifier is appropriate for your room size.

Can you turn off the display lights at night? Chevron Icon
  • Z-1000: Lights on the TruSens Z-1000 Air Purifier are subtle and have been limited to only display the active fan speed and UV setting.
  • Z-2000/Z-2500/Z-3000/Z-3500: Yes. Dimmer Mode turns off display lights, while the air purifier continues to operate in the selected fan speed.
Can I pair the SensorPod™ and the air purifier if I am not getting them to connect? Chevron Icon

Yes, in the rare occasion that the air purifier and SensorPod™ are not able to connect you can override the factory pairing and pair them again. Unplug any other SensorPods and air purifiers you own and follow the pairing instructions found in the Z-2000, Z-2500, Z-3000 or Z-3500 owner's manual.

What do I do if SensorPod™ is not connecting with the air purifier? Chevron Icon

Make sure the SensorPod™ and the air purifier are in the same room and try to move the SensorPod closer to the air purifier.

How do I know if the SensorPod™ has lost connection? Chevron Icon

If the communication between the SensorPod™ and the air purifier is interrupted, you will notice that the radio signal on the air purifier blinks.

How far can you place the SensorPod™ away from the air purifier unit? Chevron Icon

Up to 49 ft (15m). For optimal results, place the SensorPod™ on a tabletop or counter across the room, but within line of sight of the air purifier.

Does the air purifier with the standard HEPA filter work on pet odors? Chevron Icon

TruSens Air Purifiers make use of an active carbon filter to reduce the presence of odors from the air, including pet odors. For optimal results, the carbon filter should be replaced approximately every 3-4 months.

Does the air purifier with the standard HEPA filter help with allergies? Chevron Icon

TruSens Air Purifiers have been developed to reduce allergens present in the air. The 360-degree DuPont™ filter allows air to be pulled in and filtered from all directions. TruSens proprietary PureDirect airflow distributes cleaner air efficiently throughout a room.

Does the air purifier with the standard HEPA filter able to filter out smoke? Chevron Icon

TruSens Air Purifiers make use of a combination of filters to remove smoke pollutants from the air. The active carbon filter reduces odorous gases caused by smoke, while the TruSens prefilter and HEPA filter capture smoke particles flowing through the TruSens air purifier

Does the air purifier with the standard HEPA filter work on kitchen odors? Chevron Icon

TruSens Air Purifiers make use of an active carbon filter to reduce the presence of odors from the air, including kitchen/cooking odors. For optimal results, the carbon filter should be replaced approximately every 3-4 months.

What does the UV bulb do? What are some of the specifications of the UV bulb? Chevron Icon

TruSens Air Purifiers include a UV-C type ultraviolet light to reduce the growth of microbes trapped in the filter. The UV-C bulb has a peak output of 254 nanometers. All units (Z-1000, Z-2000 and Z-2500, and Z-3000 and Z-3500) allow you to control if/when you want to run UV.

Will the air purifier with the standard HEPA filter help eliminate the need to dust? Chevron Icon

TruSens Air Purifiers with DuPont™ filtration remove allergens and particulates in the air. The prefilter will capture the largest of particles (such as hair and dust), while smaller particles will be trapped by the HEPA filter. 360-degree filtration allows air to be pulled in from all directions, filtering dust and other pollutants.

Does the air purifier with the standard HEPA filter help with asthma? Chevron Icon

TruSens Air Purifiers have been developed and tested to reduce allergens present in indoor air. Reducing allergens in the air may help those with sensitivities, but a medical professional should be consulted to determine how to best alleviate asthmatic symptoms.

What are the CADR values of the air purifiers? Chevron Icon
  Z-1000 Z-2000 Z-3000
