What does the F mark on Dyson air purifier mean?

The F sign on Dyson air purifier is the sign of replacing the filter. There is a timer inside the host, and this sign will appear after 4300 hours.

In fact, the most important part of the air purifier is the filter screen. Many products fail after a long time of use, which is also the reason why the filter screen is broken, so everyone should change the filter screen of the purifier at home regularly.

Dyson patented air amplifier? Technology, the air outlet can spray strong and stable high-speed airflow, so that indoor air can circulate effectively, covering any corner of the room.

The 360-degree sealed filter system inside the fuselage consists of two layers of upgraded filter screens, in which the activated carbon filter screen with Tris activated carbon crystal can effectively remove harmful gases such as formaldehyde, benzene and nitrogen dioxide. 10 meter long PTFE HEPA filter element can purify 99.95% particles as small as PM0. 1 after more than 260 folds, thus ensuring indoor air quality.

Advantages of Dyson air purifier:

First, Dyson air purifier has two modes to choose from: individual mode and multi-person mode. In personal mode, Dyson air purifier will guide and transport warm current from a distance without sitting in front of the heater.

In multi-person mode, Dyson air purifier will release strong airflow at a large angle, so as to achieve all-round heating effect and meet different heating needs of families. Heating, air-conditioning, cold and warm two modes, warm the room quickly and evenly in winter, and send out strong air-conditioning smoothly in summer, which is applicable all year round.

Secondly, the patented technology of air amplifier air flow multiplication is adopted, and the inhaled air is ejected by the narrow air duct at an accelerated speed, and the generated air flow is introduced into the surrounding air through the airfoil guide groove, thus forming the air multiplication effect, and then conveying the strong and smooth warm air flow to any position.

Third, Dyson air purifier attaches great importance to the safety of use. Fan-free design, without any obvious heating elements, can automatically cut off the power supply when overturned, ensuring the personal safety of users when using.

4. it is a heater certified by Quiet Mark, British noise prevention association. Quiet Mark is the trademark name of Silent Logo Co., Ltd., which belongs to the operation part of British Noise Prevention Association.

Its excellent mute effect is inseparable from innovative design and technical application. Its streamlined airway design allows air to pass through the machine more quietly and efficiently. Secondly, the application of aerodynamic diffuser disperses the airflow and sends it to a specific path, which reduces the generation of turbulence.

In addition, the motor housing with special acoustic design can also effectively reduce vibration, thus further reducing noise. The excellent mute quality of Dyson air purifier makes it not disturb sleep when it is used at night, whether it is heating or delivering cold air.

Fifth, the humanized operation mode is also a highlight of Dyson air purifier. We can set the temperature, swing mode, wind power and airflow mode remotely through the remote control. Moreover, it also has a timed sleep function, and you can freely set the timed shutdown mode, from 15 minutes to nine hours, which is both worry-free and power-saving.

6. The cleaning of Dyson air purifier is very convenient, and there are no blades and safety nets that are difficult to touch. When cleaning, you only need to wipe it gently with a rag, which solves the maintenance difficulties of most products on the market at present.
