The efficiency of the products produced by Blueair is what has made the company so popular with consumers on the market. The air purifiers produced by the company use only the most quality materials and the most effective filtration systems, giving them the ability to remove most particles, gases and odors from indoor air. Since consumers mainly look for the most efficient products on the market when they are shopping for air purifiers, Blueair knew that efficiency was the most important issue to focus on with their units. The company has also focused its attention on the increasing problem of environmental pollution. Blueair has made sure to use environmentally secure materials and a safe filtration system for the home and the environment. By staying environmentally sound, the company has gained more efficiency in their air purifiers.

The preservation of energy is another issue that many consumers have placed on their priority list. Blueair's air purifiers have the ability to be set on different fan speeds. This makes them convenient for residents who may want to leave the units on overnight in order to wake up to clean air in the morning. The air purifiers can be left on a low fan speed to eliminate the airborne particles and contaminants from the air before the residents even wake up in the morning. These residents also don't have to worry about seeing a spike in their power bill by leaving the system on over night. The air purifiers by Blueair can be left on for 24 hours a day, 7 days a week and still not use too much power. The system only uses about 15 watts of electricity to run on a low fan speed. If the air purifier is run on the highest fan speed, it only consumes about 95 watts of power. The average speed of the fan inside these units uses about the same amount of wattage as a regular light bulb.

The efficiency of the filtration system inside Blueair air purifiers is attributed to the overall effectiveness of the system. The HEPASilent filter technology that is present inside the units is known to not only make the performance of the air purifier quiet, but it also is effective at removing harmful contaminants from indoor air. The efficiency of the HEPASilent filter is much higher than a simple regular HEPA filter. This type of technology is able to remove about 99.97% of all particles in the air that are 0.1 microns in size and larger. This includes most particles of dust, dirt, pet dander and other allergens that can be deemed dangerous to allergy and asthma sufferers. In addition to the Blueair HEPASilent filter, the air purifiers also contain an electrostatic system, allowing them to combine the two best and most efficiency filtration systems on the market today. The particles that may have been missed by the HEPASilent filter are then run through an ion chamber where they make contact with negative ions and pick up their charge. The pleats inside the filter are charged positively, making the particles with a negative charge incredibly attracted to the filter. The particles then stick to the filter and are removed from the air. The combination of these two technologies also aids the HEPA filter in removing the particles from the air. With the aid of the ion chamber, the HEPASilent filter doesn't have to work as hard at eliminating airborne particles from the air. The HEPASilent filter has an extended life because of the help it receives from the electrostatic technology system. Due to the dual technological filtration systems used in Blueair air purifiers, the units are known to be some of the most efficient units on the market.
