Our purifiers are designed to operate optimally in single spaces. Our purifiers do not work through walls, doorways, or travel upstairs for loft-style apartments.
As your room size will have the largest impact on your selection process, before choosing your air purifier, measure your room in square footage.
Additional information: Where Should I Place My Purifier?
If a room is larger than the purifier covers, it may be best to get more than one purifier for that room.
While using a purifier that matches the square footage of a room will be sufficient, we recommend choosing an air purifier that will cover more square footage than the actual size of the room.
For example, if the air purifier can cover up to 900sqft (BreatheSmart FIT50), we would recommend that purifier for a 700sqft room, to produce an excellent result.
