★★★★☆Our rating: 4/5•By Smart Gear Vault•Updated 4 October 2026

Quick verdict

The Shark FlexBreeze Pro Mist is the fan to buy if you want to cool down in the garden as well as indoors. It runs cordless for up to 24 hours on its lowest speed, switches between pedestal and table modes in seconds, and adds a portable misting tank for outdoor use. It's heavy and pricier than mains fans, and the mist is for outdoor use only.

Most fans stay plugged in next to the sofa. Shark's FlexBreeze range is designed to go wherever you are, from the bedroom to the patio. The Pro Mist (model FA300UK) adds a portable MistPro tank, so you can enjoy a cooling mist outdoors without a garden hose.

Who is it for?

It suits households that spend summer evenings in the garden, people with a patio or balcony, and anyone who wants one fan they can carry from room to room without hunting for a socket. If you only need a quiet bedroom fan, a mains air circulator will be cheaper and lighter.

Cordless freedom

The rechargeable battery is the main reason to choose this fan. Shark quotes up to 24 hours at speed 1, which is enough for a couple of evenings in the garden, dropping to two hours at full power. Because it runs on a battery, you can also use it during power cuts or in rooms where the sockets are in awkward places. Pressing a button releases the fan head from the pole, turning it into a table fan in seconds.

Misting

Clip on the MistPro tank and the fan sprays a fine mist into the airflow. Shark says it can lower the temperature you feel by up to 6°C, measured at 30°C with chilled water, so real results will vary. There are three mist modes and up to an hour of mist per tank. Shark designed the misting for outdoor use only, so remove the tank indoors, where two FlexBreeze modes imitate natural wind patterns.

What reviewers say

Independent reviews and retailer feedback praise its strong, quiet airflow and portability. Some owners report that the maximum speed is noisy, and there are some reports of misting tank leaks. Shark's two-year guarantee should cover genuine faults, but it's worth registering the fan when you buy it.

Pros and cons

Pros

  • Cordless, up to 24 hours on low
  • Portable outdoor misting with no hose
  • Switches between pedestal and table modes
  • Breeze reaches up to 20m
  • 2-year guarantee including the battery

  • Heavy at 7kg
  • Misting is for outdoor use only
  • Only 2 hours at full speed
  • Some reports of noisy top speed and tank leaks

UK price

The FlexBreeze Pro Mist costs more than a typical mains fan because of the battery and misting system. Prices change throughout the summer, so check the current price on Amazon UK before you buy.

Verdict

The Shark FlexBreeze Pro Mist does something most fans can't: it cools you down properly in the garden, without cables or hoses. Long cordless runtime, quick conversion and the misting tank make it a versatile summer gadget. It's heavy and pricey, and the mist is outdoor-only, so it earns four stars rather than five.

FAQs

Can you use the Shark FlexBreeze Pro Mist indoors?

Yes, as a fan. Shark says the misting tank is for outdoor use only, so you should detach it indoors.

How long does the Shark FlexBreeze Pro Mist battery last?

Shark quotes up to 24 hours on speed 1, 6 hours on speed 3 and 2 hours on speed 5, without oscillation or mist. A full charge takes about 6 hours.

Does the misting function really cool you down?

Shark says it can lower the temperature you feel by up to 6°C in a controlled test at 30°C using chilled water. Real-world results depend on humidity, temperature and distance.
