Home Air Purifiers Technology

One of the functions of a home air purifier that the consumer should be aware of is the air discharge patterns that they perform. Air can be discharged from the unit in a unidirectional pattern, or in one direction. If the air flows out of the unit at the same speed with a small amount or no turbulence, the airflow is considered laminar airflow. Laminar airflow in a home air purifier can be helpful at reducing the amount of contaminated indoor air that mixes with the already treated air that has been expelled from the unit. Having such a strong amount of airflow from the air cleaner can help the unit to reach a certain spot in the room and be sure that it has been treated and the particles have been removed. Air purifiers that use a multidirectional air discharging systems also may have their benefits when it comes to efficiency. By discharging the air in many directions, the multidirectional airflow allows the home air cleaner to mix the untreated air in the room with the treated air in the room and absorb both. Multidirectional airflow may be a good thing to look for if the consumer knows he or she will be moving about the room frequently and will need the entire room's air to be completely clean.

There are many types of performance standards that are set for air cleaners. One standard that is used for HEPA filters is called the Military Standard 282. This test is used to rate the particle reduction that occurs when an air purifier is used with a HEPA filter. Another type of test that is presented to filtering systems inside home air purifiers is the ASHRAE 52.1-76. This type of test is used to determine how many larger particles an air purifier is able to eliminate from the air. This test also measures how much dust is left trapped on the filter after the air has been circulated through the unit. The procedure test measures how much capacity of dust the filter will be able to handle before needing a replacement. The ASHRAE 52.1-76 also measures how much energy the air purifier will use in order to clean the room. However, only the highest test results of the ASHRAE 52.1-76 are actually shown to the consumers. In order to address this issue, the ASHRAE 52.2 tests are being developed in order to assure consumers complete accuracy with air purifier's statistics. This test is able to calculate how small of particles a clean filter inside an air purifier would be able to absorb. The ASHRAE 52.2 focuses on the life span of the filter and its capacity as well. The test helps the consumer to choose the correct air purifier and filter based on his or her specific situation and what specific particulates need to be cleaned from the indoor air.

With so many types of home air purifiers and technologies on the market today, it is important to know what statistics and factors a consumer should look at when shopping around. The Expert has researched and compiled information on the accuracy and purpose of these tests and procedures. From the research and help of the Expert, many consumers are now more informed and educated on what to look at when purchasing air purifiers. By knowing what numbers and measurements to look at, consumers are now able to choose the correct home air purifier for their specific situation. Purchasing an air purifier that is perfect for the specific types of particles they are dealing with can make all the difference for homeowners.
