Test Method:
Objective
To evaluate the effectiveness of White-Rogers SST1000, Honeywell F300E Lennox PCO-12C, Ionic Breeze 3.0 and Bentax USA's air purification eqiupment by comparing its reduction of airborne particles to a control's natural decay in a typical indoor environment. The environment has been designed to be similar to a typical consumer application such as homes, offices, etc. The key to our experiment is to eliminate any outside influences not consistent with a typical commercial or residential environment.
Testing Method
Test facility
The tests were conducted in a closed room 10.5 x 12 x 8 ft equipped with an exhaust system to clean the room between tests. The room also had a ceiling fan used primarily for evenly spreading the contaminants injected into the room for the most accurate measurements.
In order to test this specific equipment, a duct system was utilized to supply air to the room in order to model, as close as possible, a real indoor environment. The sypply air was taken from outside the test chamber. The air cleaning equipment was installed in this duct system which was supplied a measured amount of air into the room.
Dissemination of dust particles into the closed room
Roughly One (1) gram of dust particles was introduced into the test room by utilizing an injection system. The contaminant was spread evenly in the closed room by the ceiling fan mounted in teh middle of the room's ceiling. The fan was on as the contaminant was introduced into the room and was turned off after 60 seconds. The particle count was measured using a TSI Aerodynamic Particle Sizer Model 3321.
Temperature and humidity
The temperature was held at a level between 65 degrees F and 75 degrees F, and the humidity was held at a level between 35% and 45%. The temperature was measured by a Vaisala Temperature/Humidity Sensor Model HMW30YB.
Data logging
The particle data were recorded continuously by an automated computer data acquisition system directly connected to the TSI Particle Sizer. Data was logged every minute during the test period using a proprietary software program, the temperature and humidity was averaged over the period.
Testing
The steps of the actual testing procedure were as follows:
Commercial building
- The room was cleaned by the heavy duty exhaust system that re-circulates the air until the contamination level of airborne particles in the room is below 0.03 part/cc.
- The heavy duty exhaust system was turned off.
- The air contaminants, dust particles were introduced by an injection system and then spread evenly in the room for 60 seconds using the ceiling mounted fan.
- Measurements of the decay of the particles in the air were taken and recorded by the data-logger.
These measurements were conducted first on the controlled natural decay of the particles. After that was completed, steps (a) through (d) as described above were repeated with specific equipment turned on.

Summary
Testing of the above units was designed to simulate real world use. A test chamber duplicating typical household conditions was modified to introduce outside air processed by the units as might be seen in a standard installation.
