pureAir 500 Room Purifier

Effortlessly purify the air in an individual room with pureAir 500. Using advanced technologies including activated oxygen, ionization, and HEPA carbon filtration, pureAir 500 eliminates bacteria, viruses, odors, smoke, pollen, mold, pet dander, volatile organic compounds (VOCs), and more. These technologies help to sanitize everything in the air, walls, ceilings, floors, furniture, clothing, countertops, and other exposed surfaces.

pureAir 500’s operation is just as simple as its design; choose the continuous setting (green) for a constant ionic clean or use the burst setting (blue) with automatically timed activated oxygen to deal with tougher odors. There’s even an away setting (red) that deep cleans the air in your room while you’re out running errands.

Clean and disinfect air and surfaces throughout your home – even while you’re away!

Unlike passive filters that affect only air that passes through them, pureAir 500 projects powerful purification to the sources of pollution inside your home, continuously cleaning the air and surfaces, covering up to 850 ft2 of living space. Set your personal purification level for while you are home or run a deep clean while you are away and come home to pure freshness!

Harness mother nature’s purification power – indoors!

pureAir 500 harnesses the power of activated oxygen, HEPA carbon filtration, and ionization to destroy surface and airborne germs. Activated oxygen is nature’s first line of defense in fighting pollution of all types. Powered by natural forces such as lightning, sunlight, and waterfalls, oxygen becomes positively charged and able to destroy a whole host of harmful contaminants. 

Kill mold, mildew, bacteria, viruses, and odors – without lifting a finger!

While the naked eye can’t see most of these environmental contaminants, you can rest assured that your pureAir 500 is working overtime on your behalf to significantly reduce all types of indoor pollution as well as eliminate odors of all kinds, including those from pets, cooking, and smoking.

Remove allergens from your breathing space – and rest well!

The ionic power of pureAir 500 knocks out allergens by causing them to clump together until they fall out of the breathing space and can be swept up or caught in your HVAC filter.  

Easy to set up, easy to use

With easy setup, use, and maintenance, improving the air quality of your living environment is a breeze. pureAir 500 does not require frequent air filter replacements. Regular cleanings and a once-per-year replacement HEPA filter is all that’s required to keep your home clean and healthy.

    This little gem is something that I could not live without! It is super stylish and looks like part of the decor on my table. Cleans the air and makes breathing easier. I have two dogs that stay in the house the majority of the time and you would never know that they are inside! It really has made the air inside our home easier to breathe and has allowed me to cut back on my allergy medication which is a huge thing for me. So easy to remove and clean the filter. Love, love, love this product!

  2. John M

    I was having an issue of waking up in the morning and being all stuffed up. I have an allergy to dust and dust mites. The pureAir 500 did the trick! I have a rather large bedroom with a walk in closet and bathroom. It was more than enough. I am no longer stuffy in the morning or sneezing.

  3. Paula D

    I have the pureAir 500 system and I love it for my kitchen. It keeps the odors away after dinner is done and helps keep the kitchen stay cleaner since the particles in the air are removed not recirculated.

  4. Joel R

    With 4 kids and 1 cat the pureAir 500 has been a life saver!

  5. Jim

    An impressive maintenance and three system modes to handle the numerous situations associated in the air.

  6. Melissa B

    I have two of the pureAir 500’s – one for our bedroom and one for my home office. What a difference! I sleep better at night, I breath better during the day. When we have guests I will move them around to the common areas (they are small and incredibly portable) to help keep the air fresh. Especially if those friends have kids with germs! Both my husband and I are snoring less since we’ve been using the 500 in our room at night. I could not be happier!

  7. J Allen

    Its good and I’m pleased I have bought it – but I can’t find any information on exactly how to use it.
    I mean – what is the difference between the green and blue modes? Which mode removes odors the best and which mode purifies surfaces etc and kills mold? Does the mold disappear when it has been killed? I just would like more info than they supply.

    Hello –

    Thank you for your purchase of the pureAir 500. I’m sorry that the information provided did not answer your questions. Let me try and fix that.

    Your unit provides three different modes for purifying the air in your room:

    Ionization Mode (Green Light)
    Ionization Mode is your unit’s default mode. This mode utilizes Ionization, which charges particulates in the air until they clump together and fall out of your breathing space, and also HEPA filtration with a carbon filter for removing airborne particulates such as smoke, pollen, and pet dander.

    Purification Mode (Blue Light)
    In addition to the benefits of Ionization, Purification Mode creates safe levels of Activated Oxygen (O3), which destroys bacteria, viruses, mold, and mildew in the air and on surfaces.

    Away Mode (Red Light)
    High Power Purification Mode creates Activated Oxygen (O3) and Ionization for a powerful 30 minute cleaning cycle before reverting back to the previous mode setting.

    The ionization mode (green light) is activated when you first turn the unit on. Pressing the power button once more activates the purification mode (blue light). Pressing the power button one more time will turn the unit off (no light) after a 30 second cleansing cycle.

    Your unit also offers an away mode (red light), which can be activated by pressing the button next to the power button on top of the unit. When set to this mode, your pureAir 500 will propel a high power level of activated oxygen and ionization for 30 minutes, deep cleaning the air and disinfected surfaces in your room. This is the most powerful setting and will provide the highest level of odor reduction, mold and other pollutant removal, and air and surface purification. This mode should only be activated when no people or pets are in the room as higher levels of activated oxygen can cause temporary respiratory and eye irritation or headaches.

    Apart from the away mode, to continuously clean your air at higher level the purification mode (blue light) would be your best bet.

    Most airborne and surface particles such as mold, viruses and bacteria are not visible to the naked eye, but you can be confident that the pureAir 500 is working on your behalf to remove these pollutants from your room. Staining or other visible water damage may still remain even though the active mold spores themselves have been reduced or eliminated.

    Pro tip: If the light on your unit is bothersome, you can turn it off by pressing the lightbulb icon on top of the unit. Press the icon again to turn the light back on.

    I hope this answers your questions and I am so glad that you are happy with your pureAir 500 purchase!

    Thanks for letting us know, Melissa! We’re so glad to hear you are sleeping better!

  10. GreenTech Environmental

    We are so glad to hear you are happy with your pureAir 500!

  11. J Allen

    Thank you so much for answering.
    So it is safe to use continuously in blue mode for small dogs and myself 24/7 in a small flat?
    I am very impressed that the odors are removed. That is wonderful and for that reason alone I have recommended it to all my friends.
    Now I just want to be sure surfaces etc are sterilized from virus and the mold is killed etc.
    Thank you again 🙂

  12. GreenTech Environmental

    So glad to hear that your air has been cleaned and the odors are removed! The pureAir 500 is designed to clean and disinfect an area up to 850 square feet. Now that your space has been cleaned, if your flat is much smaller than 850 square feet, or not well ventilated, you may be able to “smell” the purification. Our purifiers are working at their best when you smell nothing but fresh air. While our pureAir 500 is completely safe to run in “blue” mode for yourself and your pet, If you are detecting a distinct purification smell, you may want to put your unit into the ionization “green” mode for at least part of time to allow the active oxygen to dissipate more. Hope this helps!

  13. Glenda R Jackson

    I love this product. My husband and I now wake up with no sore throat or stuffy nose. Also, we have a small bathroom attached to our bedroom and I no longer have mold in my attached bathroom with shower.

  14. alfred

  15. Samantha Ledford

    I have 2 pureair 500. We run it all the time. I have one upstairs and another downstairs. Our house feels and smells clean. I love it so much. We feel we are breathing clean air. One of the things I have noticed, we have grandbabies when they come over with colds or running nose they seem to get a little better but my husband and myself have not got a cold from them since having our pureair. Thanks so much
