We love our furry friends, but there's no denying they can make a bit of a mess. An air purifier can make a slight difference here and improve the air quality in your home by a measurable degree. If you're shopping for an air purifier and have pets, a few features are worth looking out for. A HEPA-rated filter will help trap fine allergens, while a washable mesh pre-filter can help prevent any tufts of hair from getting sucked into the machine.
A quick warning, however: while an air purifier can pull in short, lightweight strands of hair in its immediate vicinity, these units are best used to deal with fine, lightweight particles, like pet dander. If you need to keep your floors and furniture pet-hair-free, you might want to look at our recommendations for the best vacuums for pet hair and the best vacuums for allergies.
