IonicZone.com is proud to announce the addition of the NQ Clarifier medical grade air purifier to their product line. The U.S. made NQ Clarifier is the air purifier of choice for hospitals, medical facilities, and clean rooms, and for good reason This advanced air purification machine has an unmatched air exchange rate, over 6 times an hour in a 440 sq. ft room, nearly double that of the nearest competitor. How does the Clarifier achieve such a superior air exchange rate? It features a patented ‘topflow” air discharge system that sends the clear air high towards the ceiling. Unfiltered air enters through the bottom of the unit. Conventional air purification systems discharge clean air from the side of the unit where it mixes with the unfiltered air. This results in an actual air exchanges rate that is half of the theoretical air exchange rate quoted by the manufacturer. Independent tests have shown that the NQ Clarifier achieves nearly double the air exchanges of competitive units.
Besides the superior air exchange rate, the NQ Clarifier also features two or four high powered UVC lamps to create 13,000 to 26,000 microwatt’s of UVGI (a kill zone) within the unit. Virtually all viruses, bacteria, and mold is eradicated on the first pass through the NQ Clarifier. (Six air exchanges per hour in a 440 sq. ft room) The Clarifier also features 65 sq. ft of medical grade HEPA filtration, a pre and post carbon filter, 15 lbs of specially mixed activated carbon media, unlimited “dial” speed settings, silent operation (20 dbs on low to 55 dbs on high), and super energy efficient (100 watts on high) Competitive units use as much as 300 watts on high which will translate into about $600 more in electricity usage over 5 years over the NQ Clarifier.
The following is data from an independent testing lab that compared the NQ Clarifier to several competitive models:
PARTICLE AND SPORE TEST FOR CLARIFIER
ABSTRACT - The purpose of the test was to set up a closed system that best simulated a standard residential room. The particle counts in the test chamber would also be able to be identified and counted in a controlled scientific manner. The results tabulated and a realistic conclusion made.
PROCEDURE - A dust tight room was built with clear poly sheets mounted on all six sides onto a frame with seams carefully taped with packaging tape.
• The air sampling was performed on the outside and inside of the air chamber.
• The air sampling was then started immediately after placing the unit inside the chamber after taping all extra seams and running it on medium fan speed.
• Samples were obtained from factory supplied, 15 liters per minute vacuum pump, and each sample was run for a 10-minute collection time.
• Ambient temperature was 68 degrees F and humidity level was 50%.
• The chamber was 8 ft x 8 ft x 10 ft high.
• This chamber was sealed on all seams with plastic packaging tape. New dust free materials were used in the construction.
• Collection site was at 6 feet above floor inside the chamber and 16 inches in from the front and 12 inches in from the sidewall. The outside chamber collection site was 24 inches out from chamber walls and 5 feet above the floor. See sketch below.
• Unit was placed on the floor at the center part of the rear wall at 3" from the rear wall surface. See sketch below.
• See actual spore count sample test sheet attached, which lists the actual spores that were included in test.
SPORE CHAMBER DESIGN FOR AIR CLEANING TEST
Project # 04009-010AA
Air Quality Sciences, Inc.
Air - O - Cell Spore Trap Sampling
Sample Times for spore test
Sampling date - 5 / 18 / 98
Samples were collected and sealed with factory-supplied tape. All samples were previously numbered, placed into a box and sent to the lab for the actual spore counting. See attached sample test log sheet for the type of spores tested and cataloging.
RESULTS - Attached is the graph of the data results, which shows the rapid resultant reduction in room spore counts.
CONCLUSION - The test showed the ability to simulate a home environment and successfully reduce and maintain, over time, a very low level of particulate mater in the space. Test result show the air cleaning unit was very successful in reducing the fungal spores in the air of the test chamber and the results can be directly related to the ability of the unit to clean the air in any room, either in a residence or an office complex.

DISCUSSION OF TABLE VALUES
Theoretical Air Changes - this is a simple calculation of the size or volume of the room divided into the airflow coming out of the air cleaner. This is then converted to unit per hour
ie. Unit air flow of 350 cu ft/min x 60 min/hour = 21,000 cu ft per hour, Room volume = 20 ft x 20 ft x 8 ft = 3200 cu ft., this air change will then be equal to 21,000 / 3200 = 6.6 ACH
Mixing Factor - The most important function of an air cleaner is to clean the air. However, if this clean air does not get distributed throughout the room and to the occupants, then much of the clean air is wasted. Similarly, the dirty air needs to be drawn back to the unit so that the air can be cleaned. As much air flow as any air cleaner may have, how well it performs in retrieving dirty air and getting the clean air into the breathing zone indicates it's actual effectiveness. This relationship to air flow mixing is called the mixing factor. This factor, as detailed by ASHRAE Guidelines, will change with applications or room configurations.
According to ASHRAE, high supply and low return in a room are ideal. This model is successfully achieved by the NQ Clarifier due to its patented design. No obstructions are usually on the ceiling, therefore, all the air gets immediately up into the breathing zone from the unit, mixes completely, and is then drawn back to the unit by both the fan and due to the natural momentum and convection currents of the air.
ie. The ratio of clean air and where the clean air is best used is shown by this ratio, with 1:1 as best. These ratios were based on ASHRAE Guidelines. Units not creating this high supply-low return airflow pattern have higher ratios.
Actual Air Changes - This is the true "Effectiveness" of the unit. It relates the theoretical airflow with the mixing factor to yield the real amount of usable clean air.
ie. 1:1 times 6.6 = 6.6 air changes, 2:1 times 4.2 = 2.6 air changes
