The Healthiest Vacuums

Tips From the Allergist

•Consider the crowd. Don’t become Ms. Clean when the kids are around, because they’re closer to the ground where the dirt is.

•Go outside.Reduce indoor irritants by taking your vacuum and trash can outside to remove the dust bag or empty the canister.

•Check the filter. Generally, you should replace HEPA filters every six months, but check the manual -- each machine is different.

•Time it right. Don’t vacuum right before bed; even HEPA vacuums kick up a bit of dust, and it takes time for it to settle.
