Dyson engineer reveals the often-overlooked feature that vacuum cleaners are ‘pointless’ without – and it’s nothing to do with suction

All kinds of factors come into play when you try to understand the best vacuum cleaner to buy, but most people probably assume that strong aspiration is the most important thing on which to focus. A good suction is not not relevant – you need a certain amount of power of power to pull the dust and the debris from the floors. However, it is not all and the end, as I learned when I spoke to the engineer of Dyson Amy Wright.

“Many people assume that if visible dust and dirt are picked up, the problem is solved, but vacuum cleansing is useless in -depth filtration,” said Amy. If your vacuum cleaner has inadequate filters or loose seals, he will eventually release part of the dust and dirt he picked up in the air.

“A good vacuum cleaner is fully sealed and equipped with an advanced filtration system with several steps to ensure that all the dust collected remains trapped inside the vacuum cleaner and that only clean air is expelled in the house,” she continues.

The best Dyson vacuum cleaners in the range combine HEPA filtration with a fully sealed system. A HEPA filter captures 99.97% of particles as small as 0.1 microns. However, it will only capture the particles of the air that crosses it, this is where the sealed system comes into play.
