What is a Hepa Filter?
Hepa filters consist of a mat of fibres arranged randomly. These filters can remove at least 99.7% of airborne particles that are .3 micrometers in diameter. These particles are considered to be the most penetrating particle size. They are particluarly beneficial for asthma and allergy sufferers because the HEPA filter traps pollen and dust mite faeces which are common causes of allergy and asthma symptoms. My daughter is an asthma sufferer, so having a vacuum cleaner was an important choice to make. All vacuum cleaners which utilise HEPA filters require a more powerful motor in order to operate effectively.
Washable HEPA filter
The air that a Dyson vacuum cleaner expels is up to 150 times cleaner than the actual everyday air we breathe! Small particles like pollen and mold spores are captured in the filter which makes it asthma friendly. To seperate the air from the dirt the Dyson Animal DC uses centrifugal force included in their root cyclone technology – this means that no filter is used for actual dust and dirt particles and makes the Dyson a much more reliable cleaner which won’t lose any suction power.
