Congratulations on purchasing a PureAiro HEPA Max 870 air scrubber. In order to take advantage of the warranty plan, be sure to note the serial number and date of purchase. Serial Number……………………………………….. Date of Purchase……………………………………

When set to maximum airflow, the scrubber draws air through two types of filters- a pre-filter and a HEPA/Activated Carbon Filter.

  1. Pre-Filter
    The first phase of filtration, the prefilter, Captures initial dust and allergen particles.
  2. HEPA/Activated Carbon Filter
    The second phase of filtration, the HEPA/Activated Carbon Filter, catches smaller particles, down to 0.3 microns. Contributes to the control and prevention of the growth of bacteria, germs, and mold. Captures 99.99% of dust and allergens.
  3. UV-C Light
    UV-C light technology works with filters to enhance the elimination of airborne germs Titanium Dioxide is activated by the UV-C light to decompose remaining odor molecules caused by smoking, cooking, and pets.

Daisy-Chain Capability (Note: It is not available for 220/240V)
Using the auxiliary outlet on the control panel, you can link up to 3 units together. You can also daisy-chain the machines when they are stacked vertically (limit of 2 units).

The PureAiro HEPA Max 870 can be operated in the vertical position, as well as when stacked vertically (up to 2 units). When storing, the machines can be stacked horizontally to save space.

Removable Intake Panel
The PureAiro NEPA Max 870 is equipped with a removable panel on the intake side of the machine. The removable panel is quite useful in remediation applications, so you can draw air out of the room and create more negative pressure (use a manometer to monitor air pressure). To use panel:

  1. Remove the panel.
  2. Install the machine outside the containment area to draw air out.
  3. Cut a hole in the containment plastic that is the size of the unit’s inlet.
  4. Insert the inlet into plastic and seal the circumference tightly with duct tape.

  1. Place the PureAiro HEPA Max 870 so that it is in the upright, vertical position.
  2. Plug the machine into a standard 115-volt outlet. Note: Each unit needs 3 amps to operate.
  3. The PureAiro HEPA Max 870 can be operated in the vertical or horizontal position, depending on the exact situation. At this point, adjust the machine to the optimal position.

Variable Speed Control
The Variable Speed Control is used to adjust the power of the machine. Turn the knob in a clockwise direction, to increase the speed from maximum to minimum. The minimum speed setting is located immediately under the OFF button.

Auxiliary Outlet (Note: It is not available for 220/240V)
If more air filtration is necessary for a space, you can”daisy chain” or link up to 3 PureAiro HEPA Max 870s to the same outlet. There is a maximum amperage of 12 when the units are turned off, and a maximum of 9 amps when the units are turned on. Other equipment can be plugged into the same outlet as the PureAiro HEPA Max 870as long as it doesn’t go above the max amperage.

Circuit Breaker Switch
The Circuit Breaker Switch protects the unit if there are more than 12 amps of electricity passing the circuit. If this occurs, the switch will cut off the power to the unit.

Used to time the running time of the device. Start timing when the device is running, and pause timing when the device is stopped.

  1. Loosen the 4 locks that hold the filter board in place.
  2. Slide-out the filter panel board.
  3. Remove the used filters and replace them with new filters.


  • Always wear approved protective gear when changing the filters.
  • Filters should be changed after each remediation job.
  • If the indicator light is on, always change the HEPA/Activated Carbon Filter.


Water Damage
In this application, the PureAiro HEPA Max 870 should be placed in the center of the affected area. The air scrubber will draw in the air, filter it, then blow out the newly cleaned air. To begin the process, simply turn on the scrubber and it will start cleaning the air. Keep in mind that if you are working in a large area or one divided by walls, you may need several air scrubbers to effectively clean the air.

Odor Control
The PureAiro HEPA Max 870, when used with the HEPA/Activated Carbon Filter, is excellent at odor control, as well. Simply place the carbon filter in the pre-filter slot and it will capture a wide variety of odor-causing gas molecules, such as volatile organic compounds (VOCs), smoke, soot, and paint fumes.

Other Uses
The PureAiro HEPA Max 870 is also useful in many other applications including mold remediation, fire damage, dust control, and sewage remediation.


Breathing Hazard

  • When using the PureAiro HEPA Max 870in a containment area, always turn off power to open combustion appliances, such as fireplaces, furnaces, water heaters, and HVAC systems, to avoid the risk of backdrafting carbon monoxide fumes.
  • If the Filter Change Light illuminates during the remediation process, immediately change the HEPA/Activated Carbon Filter.

Tripping Hazard

  • Use caution when stacking units.
  • Do not stack more than 2 units on top of each other.
  • Falling equipment could cause bodily harm.


  • Always unplug the unit prior to performing any maintenance.
  • Check the power cord for damage (fraying, cuts, etc.) before use.
  • Verify that the GFCI outlet is working by powering on the machine and pressing the red GFCI test button. If the outlet is working, the”reset” button will pop up. To operate, press the reset button again.
  • To avoid electric shock, never use a water hose or pressure washer to clean the electrical components.
  • Check the pre-filter prior to operating the machine to ensure it is not clogged. If there is any sign of air flow restriction change the filter.
  • Make sure the unit is dry prior to installing clean filters.
  • When using the PureAiro HEPA Max 870 for remediation purposes, replace both filters at the same time and always clean the machine in between jobs. This will help prevent cross-contamination.
