Without getting too nerdy, HEPA stands for “high efficiency particulate air” and are filters present in most high end vacuums (if not they can be purchased separately).
When vacuuming, a genuine HEPA filter traps micro-particles of dust that would otherwise be recirculated back in to the air, picking up particles as tiny as 0.3 of a micron, think 10 x smaller that a strand of hair! That means they’re also trapping droppings from dust mites, along with pollen, mould, pet dander and tobacco particles.
A cleaner, healthier environment is of course important to everyone, however if you have acute allergies, asthma, COPD or other respiratory conditions, HEPA filters are an integral component of a safer space.
Interestingly though, how you vacuum can be just as important as the vacuum you use. Investing in HEPA filters can be a waste of money if the job is then rushed and careless. Slow and methodical vacuuming is the best way to collect up to 99.7% of matter from any type of surface.
Either way it’s worth checking your vacuum or with your cleaning team, to make sure genuine HEPA filters are fitted and being used correctly, for the health of anyone living or working in your environment.
