Is it true some vacuum cleaners can help allergy sufferers?
It’s estimated about 40% of us suffer from allergies at some point in our lives. And one way of keeping dust-mite allergy at bay is to use your vacuum cleaner regularly. But it’s important to choose a vacuum cleaner that can retain the contents of its dust bag or canister. Some vacuum cleaners have poor construction or exhaust filtration, which allows tiny particles to escape back into the room and wreak havoc on allergy sufferers. The Which? allergen retention tests show there can be significant differences, with the worst vacuum cleaners retaining less than 10% of the tiny allergen particles compared with the very best which retain more than 99% of them. Look carefully at these ratings if you suffer from allergies. Vacuum cleaners that have Hepa (high-efficiency particulate air) or S-class filters, designed to retain the particles that cause allergy attacks, should also make a difference.
