The term “the powers that be” is a phrase used to refer to those individuals who collectively hold power over a particular domain. The phrase often connotes a sense of resignation or cynicism and is used when referring to a large corporate entity or government structure that has enough power to affect change even if it is not for the betterment of the populace as a whole. Many of us see this process take place with the corporations we work for and with laws passed by local, state and federal governments.

In today’s world of social media and instant information and instant feedback from anyone and everyone on every level we have the power to express our opinions and feelings about those issues that dramatically affect us and yet “the powers that be” continue to try to convince us that  we need to follow their lead. This is especially true in the area of indoor air quality and air filtration or air purifying systems.

For years the the most commonly used air cleaner for the residential market was the electronic air cleaner. This device was considered the standard in the industry and laid claim to a number of performance guarantees that were never achieved. Yet people continued to purchase it because this was the only system HVAC contractors new how to install. And,they required very little maintenance or cleaning. The interesting part is that people didn’t realize the poor dust removal performance until medial air filters entered the scene.

Electronic air cleaners only needed to be cleaned or washed down a couple of times a year. The one big selling point to the consumer was the fact that you didn’t need to replace anything…ever. Just clean the particle collecting plates or wires on a regular basis and make sure the power pack was working correctly. When high grade media air filters were introduced into the market the HVAC contractors fought their entry with a lot of energy. While electronic air cleaners were being sold for $600.00 to $1,200 dollars installed. A filter frame and filter media unit was only a few hundred dollars and more often than not just included in the price of the HVAC system installation.

Once homeowners began to realize that the air media filters, which were usually a pleated polyester or cotton fiber material, were more effective at remove the airborne dust particles the sales  of electronic air cleaners dropped dramatically. Even though air media filters had to be replaced once every three months or so, the vastly improved dust collection was preferred.

Pure Air Systems offers a complete line of HEPA, Carbon and polyester dual-layer ring panel air filters that are very effective at removing and reducing harmful airborne contaminants. These systems are normally attached to the existing HVAC systems and in many cases can used as stand alone units. It is interesting that today, “the powers that be” now recommend HEPA or other types of media air filters over any of the electronic air cleaners currently on the market.  For more information on the complete line of commercial grade air filtration systems available from PAS please go to our website at: Or you can follow us on Twitter at: @pureairsystems
