Did you know the air quality inside your home can fluctuate, depending what is introduced to your home? Cooking, burning food, smoke, pollen, dust and cleaning products can all lower the quality of your air.

With 4 powerful fans and intelligent air quality monitoring, the Shark Air Purifier 4 automatically removes allergens, mould, bacteria and other particles from your air for all-day clean air confidence.

How does the Shark Air Purifier 4 work?

Delivers clean air, fast.

4-Fan Technology efficiently cleans air and quickly circulates it throughout the room, with 4 powerful air purifier fans. Auto mode adjusts the fan speed automatically to keep your air quality level optimum. You can also switch between speed settings manually or using the handy remote control – from air quality monitoring only, to quiet operation, to maximum cleaning.

Auto-adjusts cleaning power

Clean Sense IQ intelligently tracks your home’s air quality, automatically adjusting the air purifier’s cleaning power to keep your air quality level optimum, for all-day clean air confidence.

How? The built-in sensors detect and track air quality changes for you in real time. Auto mode then adjusts the fan speeds automatically. As air quality decreases, fan speed will increase. When your air quality reaches 100% cleaned, the fans will go into power saving standby mode.

The easy-to-read digital display reports results in real time. Simply toggle between:

  • Percentage (%) clean air – See whether your air quality is GOOD, FAIR or POOR and view the percentage of air that is clean.
  • Time left to clean – View the estimated number of minutes remaining until your air is 100% cleaned.
  • Particle amount – View the amount of particulate matter (PM) that is in your air. Switch between 2 particle sizes – PM 2.5 including smoke and bacteria, and PM 10 including dust, mould and pollen.

Choose from 3 display screen brightness levels including a ‘screen off’ setting, perfect for overnight use.

Multi-Staged Filtration

The Shark filter removes odours, captures 99.97% of pollutants and allergens at 0.3 microns, and traps dirt, dander and particles. A carbon layer within the filter removes and neutralises odours, from cooking smells to pet odours.

The display screen also clearly shows time remaining until the filter needs replacing. No need to wash the filters, they’re designed to perform optimally for 6-12 months with no maintenance needed.

Room Coverage: 34m² (Based on 3 air changes per hour)

We’re confident you’ll love your new Shark Air Purifier, offering a free 2-year guarantee for your peace of mind (upon registration with Shark, UK and ROI only).
