My husband and I were in the market for air purifiers for our home. We were recently introduced to the Filtropur SFS Sanitizing Filtration System. Unfortunately, we were unable to find any information on this product on the internet. We did however find extensive positive information on the IQAir HealthPro Plus. This led to our decision of ordering an IQAir HealthPro Plus. We were later contacted by Mark Frederickson. He believed that the Filtropur SFS was a great product and agreed to let us do our own independent test comparing the two products.
For our test, we chose two bedrooms of equal size located in the same area of our home. We flipped a coin to determine which purifier would be placed in which bedroom. We tested the particle count in each bedroom prior to using the purifiers. We turned off the ceiling fans located in each bedroom as well as the house fan. We then placed each purifier in the center of its room. We simultaneously turned the purifiers on their highest setting and closed the door to their room. We then let each purifier for for approximately 1-1/2 hours checking their particle counts along the way. To our surprise, the Filtropur unit outperformed the IQAir unit.
IQAir HealthPro Filtropur SFS
Before Use IQAir HealthPro 180 Filtropur SFS 210
At 20 Minutes IQAir HealthPro 70 Filtropur SFS 100
At 50 Minutes IQAir HealthPro 60 Filtropur SFS 60
At 90 Minutes IQAir HealthPro 60 Filtropur SFS 45

The numbers above are the readings from the Laser Particle Counter. They are the readings of the 0.3 microns. These numbers would be multiplied by 1000.
As you can see, the Filtropur unit started with the highest particle count and after 1-1/2 hours of usage ended with the lowest particle count. Simply put, it more effectively cleaned our air. Due to these results, we purchased two Filtroput SFS units.
