#3. How Air Purifiers Work to Help with Allergies

The most important components in an air purifier are the filters and motor.

Take Purivortex 201B as an example. After you plug the air cleaner into an outlet and switch it on, the brushless DC motor inside the device will start working to absorb the air outside into the device. The fan inside the purifier also functions to disturb pollution particulates and move them around to the point where they become trapped in the purifier.

The dirty air, dust, pollens, pet hair, or particles enter the air inlet and are filtered immediately by the 3-stage filters.

The first filter – pre-filter, absorbs and removes the larger dust, hair, PM10 and pollen particles from the air. The second filter – HEPA filter, swallows the finer particles that escape from the pre-filter. The third stage - activated carbon filter, eats up all the finest particles and odors, such as smoke, perfume, formaldehyde, VOCs (Volatile organic compounds). In the end, the fresh and clean air are generated from the air outlet.
