If you want your child’s nursery to have the cleanest air possible, you’ll want to set it up with an air purifier.
One of the best-rated air purifiers according to Consumer Reports is the Honeywell True HEPA Allergen Remover. Personally, I opted for the 310-square-foot version, which is probably too large for my baby’s room, but I like that the machine doesn’t have to work too hard to keep the air clean. If you have a smaller room, you can opt for the less-expensive but just as effective, rated for a 10′ x 15′ room (150 square feet).
For either model, you’ll want to also order a few replacement filters.
