ICP-988 Frequently Asked Questions
Q: What area of floor space does this unit clean?
The ICP-988 is rated to cover 50 sq. ² (538 sq. ²) or a room size of approx. 20' x 25' dimension.
Q: What filters have to be replaced and how often?
There are four filters that require replacement on the ICP-988 (two on each side). Two ULPA filters and two activated carbon/photocatalytic filters. The washable pre-filters (one on each side) do not have to be replaced. The ULPA filters can be visibly checked for discoloration and matched with a color code comparison bar on side of the ULPA filter. When this is at the darkest shade, the filter should be changed and the activated carbon/photocatalytic filter at the same time. You can optionally change the filter with greater frequency.
Q: How long to do you have to run the unit to purify the air?
That depends on pollution levels, which can be monitored by the sensor, set for various timed periods or manually controlled by the user. The air exchange rate varies from about 1/2 hour on maximum fan speed to 2 hours on minimum fan speed. NOTE: Using the optional HEPA filter in place of the ULPA increases airflow. This will decrease the air exchange rate to approximately 20 minutes.
Q: What impurities does this Air Purifier remove from indoor air?
The ICP-988's three stage filtration first traps large airborne particulate, followed by finer pollutants and vapors such as smoke, food/kitchen odors, pet dander, pollen, various other allergens, mold and fungi spores and outdoor air pollution that makes its way inside the home.
Q: What noise level does the fan produce?
The noise level of this unit is relatively quiet, producing a maximum noise level of 44dB on the highest fan speed setting. top
Q: What are negative ions?
Negative Ions(also knows as Anions) result from an atom containing more electrons than protons. When a high voltage corona discharge occurs in the air or comes in contact with ultraviolet light, the atom gains an electron, and as a result it becomes negatively charged. These processes release high quantities of negative ions into the air after (otherwise known as an Ion Shower).
Quickly after release, the negative ion cannot survive in this form and then seeks out a positively charged molecule (contaminant) to re-attach to. Then it bonds to it, dropping it to the ground and destroying it in the process. top
Q: What are the benefits to humans from higher amounts of negative ions released inside?
Many scientific and medical research studies have concluded that a surplus of negative ions in the air result in higher levels of seritonin (a.k.a. 'the mood chemical') production in the brain, enhancing ones overall feeling and mood. In addition, these studies also pointed to increased levels of brain productivity, decreased irritability and elevated energy levels, among other beneficial effects.

Indoor air typically has high levels of positive ions but low levels of negative ions. Home electronics, synthetically produced materials and the climate control process (heating and air conditioning) all contribute to higher levels of positive ions found in indoor air. In natural environments, negative ions are found in highest concentrations in natural outdoor settings such as near waterfalls, ocean crashing into rocks or just after a thunderstorm has passed and to lesser degree in fresh country air with low pollution counts. top
Q: What settings are on the control panel and LED display? What are their functions?
The control panel (located on units front face) has a bright blue LCD screen visible at night. Buttons are described in detail on the product page (click on intelligent features). The remote controller uses a 3V lithium battery also can be used to select desired settings. There is also an in-built tray on the unit for remote control storage. top
Q: How do the UV lights sterilize the air?
The Ultraviolet light uses a UVC spectrum to concentrate its wavelength at a short range to destroy very small bacterial viruses and mirco-organisms. So as the air passes over the UV light, the sterilization process occurs. In addition, the UVC light also contributes to further ionization of the air as explained above - refer to Negative Ions). top
Q: How many hours do the UV tubes last? Where can I get replacement UV lamps and filters. What is the cost?
On average, the tubes last about 3,000 hours. The replacement bulbs can be purchased directly from Purifion Canada for $10.00/ea. You can also buy a set of 2 UV lamps and the 8 filters (4 ULPA & 4 Charcoal Tio³ Filters) for $86.99 + shipping and can be purchased here. NOTE: Running the UV lamps for sterilization is an optional feature. top
Q: How does the titanium dioxide coating on the activated carbon filter work with the UV light to further purify the air?
The activated carbon filter contains charcoal granules which absorb gases, vapours and odours. One side of filter facing the UV tube is coated with titanium dioxide. Titanium Dioxide also referred to by its chemical formula TiO², it is harmless, opaque and approved for use in many products by the FDA.

When the UV light rays hit the titanium dioxide surface, a chemical reaction occurs which produces what are known as hydroxyl radicals. These radicals quickly react with VOC's (Volatile Organic Compounds), micro bacteria and viruses to convert them into non-organic matter in the form of water and CO², thus rendering them harmless.

Other commercial and product uses for titanium dioxide include but are not limited to, anti-fogging and pollution resistant surface coatings, pigmentation for toothpaste and white paint, sun block agent and water purification. top
Q: What sort of warranty do I receive on Purchase?
A one-year warranty on parts and labour, with a replacement unit given to the purchaser, provided it was not damaged by misuse. top
