Product Information

Allergens, germs and odors, beware! The Hi-Performance Air Purifier is an ideal purifier for allergy and asthma sufferers providing cleaner, fresher air to breathe and relief from allergy symptoms. A True HEPA filter relieves allergies by capturing 99.97% of dust and allergens as small as .3 microns in size. According to the American Academy of Pediatric Allergy and Immunology, doctors recommend HEPA air filtration to reduce exposure to indoor asthma triggers. A large activated granular carbon filter attacks common household odors including those caused by smoke, cooking and pets. And, it works to reduce the harmful VOC's that are emitted by common household products and cleaning chemicals. UV-C light technology kills germs including staph, influenza and rhinovirus. An ionizer option is built into the unit and can be turned on to boost allergen control. The ionizer emits negative ions that attract microscopic allergens to form larger particles that can be easily trapped by the True HEPA filter. The purifiers stands about 27" high and provides powerful air cleaning in rooms up to 378 sq. feet. Tested by independent labs, the CADR ratings are high with 244 (smoke); 310 (dust) and 346 (pollen). This air cleaner is ARB certified and complies with federal ozone emissions limit.

    What is CADR?
    CADR stands for “Clean Air Delivery Rate” which indicates the volume of filtered air delivered by an air purifier. CADR ratings show the effectiveness of how efficient the air purifier is at capturing fine particles from things like tobacco smoke and plant pollens from the room.

    How do I know when I should replace the filter?
    It is recommended that you replace the Combination Filter every 6 months — depending on use — to maintain an optimal level of air purification. When the filter turns from white to dark grey or black, it should be replaced with a new one. If the filter is still white, it does not need to be replaced.

    What is UV-C light?
    UV-C is part of the ultra-violet light spectrum that is filtered out by the earth’s atmosphere. The “C” stands for the particular frequency of UV light that kills germs.

    Why is UV-C light so effective?
    UV-C light is highly effective at penetrating thin-walled germs like viruses and bacteria. The light alters the genetic structure of the germ, and they die.

Powerful, Quiet and Sleek

I've owned other air purifiers and this one is definitely the best. It is very powerful/high volume on the highest speed setting. I had a weird odor in a room and turned it on and closed the door. I'd say it was no more than a few hours later when I returned and the smell was gone. After that, I wanted to use it just to normally filter the air, I plugged it in and put it on medium speed. It is quiet and barely audible even though it is still doing a lot of air filtering. I also like the modern design and built-in handle.

By: Scott

Great for apartments

Even though it is expensive, when the setting is on Low or Medium it is VERY QUIET. It is in my living room, and within a few hours of turning this on, the air feels crisper. It even works when cooking, getting rid of some of the smell, as my kitchen has very bad air circulation.

Great air purifier - Recommend highly

Love this air purifier. Works very well in our large bedroom, and the air always smells sweet and clean. I find it very quiet, especially on the low setting, which we usually use. Unit is small enough to fit easily into a corner, although you must allow some space around it per the directions. I think it's worth every penny and would like to buy another.

This is a life-saver. My one year old has allergies, bad. From the day he was born he had a runny nose and constantly goopy eyes. We just were hoping he'd grow out of it. Well I got tired of giving him baby Zyrtec so my husband splurged and bought this. Omg it's amazing. It's in my sons room and his allergies are nonexistent now. He's doing wonderful. It's pretty quiet, we leave it on full blast while he's sleeping with no problems. It's expensive, but worth every penny. Zyrtec, probiotics, Kleenex, doctors visits now that's expensive. I think this is an investment. We are currently saving up to buy one for our room. If your battling allergies I'd say just get it.
