This article contains the FAQs for the HE400UK Shark™ Air Purifier 4.
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.
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.
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.
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.
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.
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.
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.
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.
Your Shark™ Air Purifier 4 comes with 1 pre-installed filter and a remote control. Please be sure to remove the filter from its packaging before first use.
- 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.

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.
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.
