You'll love the Blueair Air Purification System, unless, of course, you're an airborne particle. The 501 effectively purifies air in rooms as large as 580 square feet. While traditional air cleaners trap particles using either mechanical or electrostatic technology, the Air Purification System combines the best of both. First, the filters contain millions of ultra-thin fibers that mechanically trap even smaller particles. Then it goes a step further by giving a negative charge to particles, which magnetically attracts them to the filters, giving your room an air exchange six times per hour. To minimize drafts, it disperses clean air on three sides through an area six times greater than the average air cleaner, while it is very quiet (has 4 speeds, on level 1, it is nearly impossible to hear). The Air Purification System is made of galvanized Swedish steel, the same material used in high quality telecom equipment, and is constructed to have an exceptionally long product life with casters for mobility. No assembly required. We think this product is so good, we use them in our offices! New improvements have increased energy efficiency by 30% and reduced noise levels by 12%. Particle Filters (item #4793), and Smokestop Filters (item #4797) sold separately, both in sets of 3. Please see Other Info tab for filter information. From Blueair.

"Take The Blue Air Allergy Test"

1. True or False: Allergies to cats are more common that allergies to pollen.
2. True or False: Allergies may be hereditary.
3. True or False: Molds are worse in warm weather.
4. True or False: You can drown dust mites. That's why washing bedding and rugs is so important.
5. True or False: There is nothing you can do to calm your indoor allergies.
6. True or False: Pets with short hair or no hair are OK for allergy sufferers to live with.


1. False: 35 million people suffer from upper respiratory symptoms that are allergic reactions to airborne pollen; up to 10 million Americans are allergic to cats and 2 million develop severe allergic reactions to insect stings.
2. True: Allergies have a genetic component. If one parent has allergies, chances are 1 in 3 that each child will have an allergy. If both parents have allergies, it is much more likely (7 in 10) that their children will have allergies.
3. True: Molds, too, are light and can be easily carried by air current. The mold season often peaks from July to late summer but can thrive year round indoors.
4. False: Dust mites can't be drowned. The only way to get rid of them in washable items like rugs is to use water that is hotter than 130°F. It's actually the waste product of dust mites that cause the allergy.
5. False: Many people are turning to indoor air purifiers to help relieve their allergies indoors. Air purifiers such as Blueair, eliminate up to 99.97% of all airborne contaminants.
6. False: The major allergen from animals is not their fur, but proteins secreted by skin glands that are found in dander, proteins in the saliva that stick to the fur and proteins found in the animal's urine.
