  1. Q: How large is the Pure & Clear Air Purifier?

    A: 12" Tall, 9" Wide, 12" Deep


  2. Q: Where should I place the Pure & Clear Air Purifier?

    A: It is best to place it in the most occupied area of the home as high up as possible. A good choice, for example, would be in the living room on a bookshelf.


  3. Q: How does the Pure & Clear Air Purifier compare to others on the market?

    A: Unlike most air cleaning systems that require the pollutants to be brought to the device, called passive devices (like a filter), the Pure & Clear Air Purifier is proactive. It attacks pollution at its various sources throughout the indoor environment including in your breathing space and on surfaces. The Pure & Clear Air Purifier will literally purify anywhere the air can get to--reducing particles, breaking down dangerous gasses, and inactivating bacteria, and viruses.


  4. Q: How does the technology work?

    A: The Pure & Clear Air Purifier uses four distinct technologies to break down/destroy pollutants such as the thousands of volatile organic compounds (VOCs), odor causing compounds, bacteria, viruses, and particulates (dust/dander) that are found in the indoor environment. These technologies include:

    • two types of ionization (Pulse and Needlepoint)
    • photocatalytic oxidation (PCO)
    • activated oxygen
    • electrostatic filtration


  5. Q: How do I determine what mode I should use the Pure & Clear Air Purifier in?

    A: More is not necessarily better when it comes to air purification. The goal of the Pure & Clear Air Purifier is to create a natural purification like we find in fresh mountain air. To begin, always place the purifier in NORMAL MODE. After two or three days, try the HIGH MODE setting at 250 ft2 as long as the room the purifier is in is no less than 250 ft2. Over the next few days, gradually increase the square footage setting up to the area of the environment being treated (NOTE: Do not exceed the square footage of the enclosed area. Do not count rooms closed off by doors or other areas where air does not flow freely between rooms.). If at any point you find the purification to be too strong, reduce the square footage setting. You may even choose to revert back to NORMAL MODE if the lowest setting in HIGH MODE is not pleasant for you.


  6. Q: What if I need longer than sixty days to evaluate the Pure & Clear Air Purifier?

    A: Customers typically see a noticeable difference in the indoor air quality within three to five days. In some cases, results are seen in just a few hours. This, of course, depends on the condition of the environment.
  7. Q: Why is the Pure & Clear Air Purifier so expensive?

    A: Keep in mind that the Pure & Clear Air Purifier has some of the most advanced stand alone air purification technology available. Other similar types of purifiers that are not as effective often cost two to four times as much as the Pure & Clear Air Purifier. HEPA filters can cost as much as $1,500 over a five year period of time. The Pure & Clear Air Purifier delivers results by dramatically improving your indoor air quality for much less than other systems available.


  8. Q: Does the Pure & Clear Air Purifier oxidize metal or rubber products?

    A: The purifying oxidizers created by the Pure & Clear Air Purifier when operated in NORMAL MODE or when set to a proper setting in HIGH MODE are not dispersed in levels that will adversely affect metals, plastics, or rubber items in your indoor environment. When using the AWAY MODE (for use only when the area is unoccupied by humans and pets) a level of ozone is generated that helps sanitize the area. Continuous exposure to elevated ozone levels can cause a breakdown of natural rubber products and the oxidation of metal. For this reason, the use of the AWAY MODE should be limited to two to four times per month with a maximum of two hours per session.
  9. Q: Since the Pure & Clear Air Purifier uses an ionizer; will it cause a Black/Gray Wall effect?

    A: No. The Pure & Clear Air Purifier ionization technology projects the ions out the front of the purifier. As long as the Pure & Clear Air Purifier is directed towards the middle of the room, there should be no instances of Black/Gray Wall. Black/Gray Wall effect occurs when ionizers negatively charge the walls, which will attract particulates. However, since many of the particles drop to the floor, they must be swept up or vacuumed and disposed of.


  10. Q: What happens to the particles that are being removed from the air in the room?

    A:The two forms of ionization in the Pure & Clear Air Purifier cause ultra-fine and larger particles to become negatively charged Because most particles in the indoor environment are positively charged, the particles attract each other and clump together. This causes the particles to gain mass and either get pulled into the HVAC filter or drop to the floor at which point they must be swept up or vacuumed to be disposed of.


  11. Q: Can the Pure & Clear Air Purifier be used in a smaller area?

    A: Yes. However, when used in a small (up to 250 square feet), the unit should be operated in NORMAL MODE. In areas over 250 square feet the unit can be operated in HIGH MODE. (NOTE: Do not exceed the square footage of the enclosed area. Do not count rooms closed off by doors or other areas where air does not flow freely between rooms.)


  12. Q: Is the Pure & Clear Air Purifier harmful for people and their pets?

    A: Not when in NORMAL MODE or when set to the proper area.


  13. Q: Can one Pure & Clear Purifier cover the whole house?

    A: It can, but this certainly depends upon the size and layout of the house and how much pollution the Pure & Clear has to deal with. The unit can benefit and be more effective if it is placed in such a way that after delivering the purification to a large area it can be picked up by the air return and distributed through the duct system to other parts of the home.


  14. Q: Can the Pure & Clear be moved around? (To avoid using multiple units.)

    A: Yes. The unit is portable. That is one of its great features. We recommend you locate the best spot in your home that makes it most effective. Typically this is mounted high in a family room close to the kitchen area. Even so, you may find from time to time that you have a reason to temporarily relocate it to deal with odors.


  15. Q: Does the Pure & Clear Air Purifier need to run all the time?

    A: The Pure & Clear is designed to be left on 24/7. This allows the advanced technologies of the unit to maintain a clean environment, rather than having to play catch up each time the purifier is activated. Even during periods when you are away from the home for an extended period, it is best to leave your purifier on to reduce bacteria levels, which are common when a home is closed up for an extended period.


  16. Q: Is there any maintenance necessary on the Pure & Clear Air Purifier?

    A: Yes. The unit should be cleaned on a regular basis (typically once a month). A small mesh plate, as well as the rear filter, needs to be cleaned according to instructions in the Owner’s Manual. In especially dusty or smoky environments, we recommend the use of an additional pre-filter to protect your Pure & Clear and keep it cleaner. The PCO Cell (UV lamp module) requires replacement after its recommended lifespan has been reached.


  17. Q: How long does the PCO Cell (UV lamp module) last?

    A: The operational life of the PCO Cell is approximately 9,000 hours. If you use the product around the clock, it will last you over a year. In fact, the lamp module has a one-year warranty. The manufacturer recommends replacing it annually..


  18. Q: I understand that it uses TiO2 or Titanium Dioxide in a reaction with UV light to produce OH. Isn’t TiO2 a toxic compound capable of causing lung damage? Aren’t OH molecules potentially dangerous too?

    A: TiO2 is “Non-Toxic”! TiO2 is used in paints to create bright white finishes, as well as in toothpaste, cosmetics and many other products. OH molecules are oxidants. When found in high concentrations, they can be irritants. The life of an OH molecule is less than a second. Within that time frame, it will have reacted with an organic and will have been converted to carbon dioxide and/or water.


  19. Q: Do OH molecules have any smell?

    A: No. Though, some people may detect a slight metallic odor associated with the photocatalytic activity but that smell is not as a result of OH molecules.
  20. Q: Is it a problem if the concentration of OH in the air is too high?

    A: The Pure & Clear Air Purifier ionization technology projects the ions out the front of the purifier. As long as the Pure & Clear Air Purifier is directed towards the middle of the room, there should be no instances of Black/Gray Wall. Black/Gray Wall effect occurs when ionizers negatively charge the walls, which will attract particulates. However, since many of the particles drop to the floor, they must be swept up or vacuumed and disposed of.


  21. Q: What if the PCO light in the unit does not come on when the Pure & Clear Air Purifier is turned on?

    A: First, make sure the wall outlet has power and the green LED indicator on the external AC to DC power adapter is lit. Then verify the purifier is turned on and the fan is operating. Next, check that the PCO Cell is properly plugged in. You’ll need to remove the rear grill and filter, and then ensure the plug from the PCO Cell is firmly seated in its socket. If the unit still does not work, contact customer service. .


  22. Q: How many positive ions does the Pure & Clear Air Purifier produce along with negative ones?

    A: The Pure & Clear Air Purifier produces only negative ions, approximately 1.5M ions/cu cm at a distance of 1 meter. Because the majority of pollution in the indoor environment is positively charged, adding negative charges causes particles to attract, clump together and then fall from breathing space.


  23. Q: How much ozone is released from the Pure & Clear Air Purifier?

    A: When used in NORMAL MODE, no ozone is used in the purification process. In HIGH MODE, when the purifier is adjusted for the area being treated, ozone levels are typically 0.1 to 0.3 PPM, well below the safe and “natural” level set by the EPA. It is important to set the square foot setting based upon the ventilated space (where air can get to) and not the entire square footage of the home.


  24. Q: How are negatively charged ion molecules collected after attaching to the positively charged ones in the atmosphere? Is there a mechanism that provides for this in the Pure & Clear Air Purifier?

    A: The process of ionization involves the negatively charged ions coming from the unit, to travel throughout the home attracting positively charged particulates. The process is called agglomeration. The particulates become larger and heavier and fall to the surfaces, i.e. furniture, table tops, counters, floors, and are taken care of by normal home cleaning procedures (sweeping and vacuuming). Because these particulates are heavier than air, they do not get re-airborne. There is no mechanism inside the unit to collect these particles other than the rear filter, which is primarily responsible for keeping the unit itself clean.


  25. Q: Is the Pure & Clear Air Purifier UL listed?

    A: Yes, the Pure & Clear Air Purifier is UL listed. The UL mark can be found on the AC/DC Power Adapter..


  26. Q: We have been using our Pure & Clear Air Purifier for several days and started to experience burning eyes. We turned it off and have not experienced that sensation again. What could cause the burning eyes sensation?

    A: If the purifier is being used in HIGH MODE (square foot setting), the setting is most likely too high and needs to be reduced or set to normal mode. If the purifier has been used only in the NORMAL MODE (PCO setting) the issue can typically be resolved by moving the purifier to a larger area and ensuring the unit is placed at 6 feet, such as on the top of a bookcase.


  27. Q: What is the warranty for this product?
