CLARIFIER STANDS OUT IN ALL CATEGORIES AS THE BEST PRODUCT CHOICE
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
Effectiveness** - This is how well any stage of the unit performs in an actual room, as it relates to the highest standard of another unit. We use it here to compare carbon benefits. If the best standard carbon weight is less than 15 pounds, then effectiveness is a simple percentage of that 15 pound standard multiplied by the odor adsorption ability of the carbon. Not only does the Clarifier use 15 lbs. of carbon, but it also includes potassium permanganate, which has better adsorptive qualities (6% reagent content vs. 4%), so therefore pound of pound it is more adsorptive than standard carbon, so this is also factored into the effectiveness.
ie. Less than 1 pound = 1/15 = .0666 times 4/6 = 4.4% 13 pounds = 13/15 times 4/6 = 58%
