Yes, many of these high end air cleaners are very effective, yet can be expensive to have installed and maintained. The Elevated Air products use scientifically correct designed products to get the same efficiency as products that cost twice as much and our easy to replace media cost about the same as high end allergy filters that you buy at retail outlets. These allergy filters do a good job collecting the larger airborne particles yet cannot capture the smallest of allergens that the Elevated Air Polarized Media Air Cleaner removes from the air. 98% of the particles in the air that you breathe measure below one micron in size and are invisible. The Elevated Air Polarized Media Air Cleaner removes 97% of these particles from the air you breathe.
