Air purifiers work by drawing air from the room into the system with a fan, clean the air, and then release the clean air back out into the room.
When you consider purchasing an professional air purifier, it’s important to know how the actual system works. As described above, if you want an air purifier that both eliminates particulate matter and potentially dangerous chemicals and odors, you will want an air purifier that contains activated carbon or a UV purification system.
You also need to know the power of the machine you are purchasing and its general effectiveness. Air purifiers, whether they contain HEPA filters, or use electrostatic systems, come in a range of prices.
Price is often a good indicator of the quality of the product you are buying. Of course, a smaller unit may prove to be a quality product but with a lower price tag. A lot of high end air purifiers utilize a pre-filter as well as the HEPA filter. These air purifiers give extended life to the HEPA filter by removing some of the larger particulate matter before it can contact the HEPA filter, thus extending the lifespan of the HEPA filter.
To be effective, the pre-filter requires regular cleaning to remove dust build up which will otherwise reduce the air purifier’s performance. Efficiency is important to consider when purchasing an air purifier. Even though a HEPA filter can remove 99.97% of dust from the atmosphere, that does little to help if the actual air purifier is only cleaning a fraction of the air in the room.
