IAQ Calculator

The IAQ Calculator will help you find the right LakeAir product. Each LakeAir brand air purifier provides a level of air cleaning capacity. This capacity  is measured in cubic feet per minute (cfm). The size of the room and the number of air changes per hour are used in the application on this page.. Follow the steps below to help you determine which model will effectively clean your home or work space. If you are unsure which LakeAir Air purifier is best for your specific situation call our customer service line (800-558-9436) for more assistance.

Inhabitants and Use

Another very important factor to consider is how many people occupy an area.    You need more purification for a bedroom with 3 children compared to 1 child. Room use is important too. A room where you store equipment needs much lower  IAQ than a class room. What types of inhabitants is also important. Children and the elderly require more clean air than healthy adults. Use the higher end numbers for more inhabitants. Use  higher IAQ standards when children and elderly are involved. Inhabitants with asthma and other respiratory illnesses require cleaner air.

Pollutant Concentration Suggested Air Changes Per Hour Typical Application
Low 4 – 8 Living rooms, bedrooms and waiting areas
Medium 9 – 12 Computer areas and kitchens
High 13 – 16 Restaurants, bars and banquet halls
