In addition to ensuring your home or office remains odor-free, this air purifier was designed to remove particles, allergens, dander, and smoke in rooms up to 497 square feet. Designed with four fan speed settings, you can choose how quickly your room is purified and use it in the ultra-quiet sleep mode setting.

An LED display provides live status updates so you'll always know when to replace the included filter and stay aware of changes in air quality. Insignia also threw in a convenient timer that automatically shuts off the air purifier after 1, 2, 4, 8, or 12 hours. Plus, there's a child lock setting you can use so your young ones won't accidentally change any of your chosen settings. Note that you'll have to change out the filter now and then and these are sold separately.

This air purifier is a great way to improve indoor air quality in your home or corner office. Check this deal out while it lasts.
