This article contains the FAQs for the HE600UK Shark™ Air Purifier 6. 

Why is my air quality reduced even when I am not cooking or doing any activity?

Air quality can change for a variety of reasons. Clean Sense IQ™ takes a reading of microscopic particulate matter in the room and displays the air quality accordingly. Everyday activities can agitate particles, such as settled dust, into the air, which will decrease air quality.

Can I leave my air purifier on at all times (24/7)? How does that affect lifespan of the product?

While your air purifier can be left on 24/7, longer runtimes may shorten the filter lifespan. Shark™ recommends keeping your unit in Auto Mode to extend the filter lifespan.

Why is my air quality at 100%, but the air smells bad?

Air quality is measured by the amount of particulate matter in your air. To accurately calculate the percentage of your air that is clean, Clean Sense IQ™ tracks 2 distinct particle sizes:PM2.5, and PM10. However, odours are not included in this calculation. Rest assured, our filter technology is actively capturing odours and allergens while you run your unit.

Why is my air quality always at 100%?

If your air purifier display reads 100%, your air quality is good. However, air quality will fluctuate as you introduce pollutants into your home. Activities like smoking, cooking, dusting, or spraying cleaning products can add more pollutants to your air. Clean Sense IQ™ tracks this fluctuation in real time and alerts you when your air quality decreases. 

Air quality is measured by the amount of particulate matter in your air. To accurately calculate the percentage of your air that is clean, Clean Sense IQ™ tracks 2 distinct particle sizes: PM2.5, and PM10. However, particles in your air can be both larger and smaller than this range. Rest assured, our True HEPA technology is cleaning the air by capturing odors and 99.97% of particles 0.3 microns or larger.

Why is my air quality never at 100%?

If your air quality never reaches 100%, make sure that the filter is properly installed without its original plastic packaging. The filter should be replaced every 6-12 months, but depending on the level of particles present in the air, you may need to replace the filter more often. Your air quality may also fluctuate depending on your surroundings. Activities like smoking, burning candles, running a humidifier, and cooking can add more pollutants to your air. Survey your environment and remove anything that could be causing low air quality.

How do I know if my air purifier is in Auto Mode?

The Auto Mode setting automatically adjusts the fan speed of your air purifier based on the air quality. If the air quality decreases, the fan speed will increase.

To activate Auto Mode, select the AUTO button on either the top control panel or remote control. When this option is selected, the AUTO button will appear brighter than the other buttons.

To turn off Auto Mode, press the AUTO button again.

How do I change the settings on my air purifier?

To change the settings on your air purifier, press the buttons on either the top control panel or remote control.
Air purifier settings include Fan Speed, Timer, Auto Mode, Filter Life, Brightness, and Air Info Views.

How can I tell if my air is clean?

The illuminated air quality rings on the front and top display screens will change color as your air quality changes.

The ring color indicates the air quality:

  • Blue = good air quality
  • Amber = fair air quality
  • Red = poor air quality

By pressing the AIR INFO button on your unit or the info icon on the remote, you can switch between air quality view options. Options include percent clean, time to clean, and the amount of PM2.5, and PM10 particles in the air surrounding the unit.

What accessories are included with my air purifier?

Your Shark™ Air Purifier 6 comes with 1 pre-installed filter and a remote control. Please be sure to remove the filter from its packaging before first use.

How do I set up my air purifier?
  1. Set up the unit on its base on a level floor. For best results, set it up in the space you spend the most time in, such as the kitchen, living room, or bedroom. Make sure the unit is at least 3 inches (8cm) away from all walls, large objects, or electronics.
  2. Before plugging in the unit for the first time, you must remove the filter and take it out of its packaging. First, remove the filter cover from the back of the unit. Press the tabs near the top and pull the cover toward you.
  3. Remove the filter from the unit and take it out of its sealed plastic packaging. Then, reinstall it into the unit. DO NOT run the air purifier unless the filter is removed from its packaging and installed correctly.
  4. With the filter installed, replace the filter cover. Insert the tabs on the bottom of the cover into the slots on the unit. Press the top of the cover, then the sides, until it clicks into place.
  5. Plug the unit into an electrical outlet and press the power button on the top control panel or on the remote.
  6. Once the unit is on it will begin to read the air quality in your room. This calibration process will run for a few seconds and is indicated by the rotating lights the top of your machine. Once the calibration has completed, you can begin to customize the settings on your unit.
How do I maintain my air purifier?

Both the exterior and the interior of your air purifier will need to be dusted periodically. For best results, clean the unit every two months or as needed.

When cleaning dust from the exterior, use a microfiber cloth to remove debris from the surface of the unit. To sanitize, wipe down the exterior with a warm, soapy cloth. Avoid excess water and abrasive chemical cleaners to prevent damage.

When cleaning dust from the interior, lift off the filter cover, remove the filter, and use a vacuum cleaner or a microfiber cloth to remove dust and debris from the interior of the unit. DO NOT use abrasive chemical cleaners on the inside of the unit. DO NOT insert cleaning instruments into the fan outlet.

Can I use any replacement filter?

Only use Shark™ brand filters when operating your air purifier. Other filters may cause damage to your unit or not perform to the same high level of particulate capture. Replacement filters can be purchased at sharkclean.co.uk.

Can I wash the filter?

No, the filter is not washable. Keep the filter away from water and dispose of it when dirty.

How do I change the filter?

The FILTER LIFE button on the top control panel will flash when it’s time to replace the filter. To change the filter, complete the following steps:

  1. Turn off the unit and unplug it before removing or installing filters.
  2. Remove the back cover from the unit by pressing the tabs at the top, then pulling the cover toward you.
  3. To remove the old filter from the unit, pull it out by the tab near the top. Place the old filter in a dustbin and dispose of it.
  4. Remove all packaging and wrapping from the new filter.

  6.  Plug the unit back into the outlet and turn it back on to begin calibration.
  7.  After installing a new filter, press and hold the FILTER LIFE button on the top control panel for 3 seconds to reset the filter timing system. The unit will beep when filter timing is properly reset.

Note: Do not get filters wet. Do not place filters in the dishwasher or washing machine - they are not washable and must be replaced with new ones.

How often do I need to replace the filter?

Shark™ recommends changing the filter every 6-12 months. When the filter needs to be changed, the FILTER LIFE button will flash.

If you or a member of your household is sensitive to allergens, you may benefit from changing the filter more frequently.

To check the remaining filter lifespan, press the FILTER LIFE button on the top control panel to show the number of hours remaining before the filter needs to be changed.

What is PM?

PM stands for particulate matter. These particles are microscopic solids or liquid droplets that are suspended in your air and can be inhaled and cause health problems.

Using Clean Sense IQ™, the Shark™ Air Purifier 6 tracks 2 distinct particle sizes: PM2.5, and PM10. Each of these particulate sizes corresponds to common household pollutants.

  • PM 2.5 includes smoke and bacteria
  • PM 10 includes dust, pollen, and mould
Does this air purifier reduce odors?

Yes, the Shark™ Air Purifier 6 filter is equipped with activated carbon pellets which are designed to absorb household odours and VOCs (volatile organic compounds) such as cigarette smoke, pet odours, cooking smells and formaldehyde.

Does this air purifier have a HEPA filter?

No, but this air purifier features a high quality filter that captures 99.97% of particles 0.3 microns or larger.
