Vacuums
Vacuums that keep fine dust inside the machine instead of blowing it back into the room.
What we look for
We look for
- A sealed system: the maker says the whole machine is sealed, not only that a HEPA filter sits somewhere inside it. An Asthma & Allergy Friendly certificate, which tests for leaks and emptying, is the best evidence.
- HEPA where it counts: a HEPA filter (H13 or “True HEPA”) on the exhaust, or before the motor in a sealed machine, ideally with a published test of what comes out.
- Mess-free emptying: a bag, or a bin you can empty without a dust cloud. Bags hold fine dust and allergens best.
- Parts you can buy: filters, bags and batteries priced and sold separately, with a stated change interval.
We avoid
- “HEPA filter” claims on machines that let air leak around the filter.
- Emptying a bagless bin indoors when someone in the home has dust allergies or asthma.
- UV lights, ionizers and other “sanitizing” extras sold as health features.
