There is a complex formula used to measure the volume of air needed. The measurement unit is CFM. CFM stands for cubic feet per minute. CFM is the amount of air that passes through a device. In this case the device is an air purifier.
The amount of the air volume is determined by the size of the fan and motor. The amount of resistance caused by the filter also plays a role. The size of the inlet and outlet also come into the equation. A large fan will move more air than a small fan. A dense filter may trap more particles. However it will reduce the volume of air. An air purifier maybe cute and small but not be able to produce enough clean air.
LakeAir has several models each designed for a different size area. The noise levels vary from unit to unit. The filter that allows the most air to pass through while cleaning the most is an electrostatic filter. We recommend this technology most often for low noise, best cleaning efficiency and highest volume of clean air.
Each LakeAir brand cleaner provides a level of air cleaning capacity which is measured in cubic feet per minute (cfm). This is determined by the size of the room and the number of air changes per hour. Follow the steps below to help you determine which model will effectively clean your home or workspace.
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 |
Example
A 15’ X 15’ X 15’ living room
Step 1: 15 x 15 x 15 = 3375 ft3
Step 2: 3375 ft3 / 60 minutes = 56.25 ft3 per minute
Step 3: 56.25 ft3 per minute x 8 air changes per hour ( an average polution level ) = 450 cfm (cubic feet per minute)
Step 4: A LakeAir Maxum HEPA Tabletop model would be ideal for this space. The Maxum Line is available in electrostatic, media filter and HEPA filter models.
The CFM calculator uses a variety of units to perform its calculations. These units include cubic feet per minute (CFM), feet per minute (fpm), and inches per minute (IPM). Each unit is used to calculate a different aspect of the airflow through a given space. The CFM calculator is designed to be used with both standard and metric units. Standard units are used when the dimensions of the space are known.
The purpose of the CFM calculator is to help you determine the proper airflow for your HVAC system. By inputting the dimensions of your room, the calculator will determine the number of cubic feet per minute (CFM ) of air that you need to maintain comfortable temperatures.
The CFM calculator is a tool that is used to calculate the air flow in a room. It is a simple tool that allows you to input the dimensions of the room and the desired air flow rate. The calculator will then output the necessary CFM rating of the fan that you will need to achieve the desired air flow.
