Find the root cause, then treat it

Studies referenced by the Environmental Protection Agency show that air pollutants may be up to five times higher inside a home than outdoors. If that worries you because of health issues, allergies, or simply general concern for yourself and your family, R.A. Heating & Air Conditioning in Evansville can help you look into it.

The approach starts with a question, not a product. The team first determines whether there is a problem in your home, then targets it with effective technologies, locating the root cause of your air quality issues before suggesting a fix. One option they offer is the iWave-R air purifier from Nu-Calgon.

The iWave-R, in plain terms

The iWave-R uses needle-point bi-polar ionization, meaning positive and negative ions are released into the air. According to Nu-Calgon, the process reduces allergens, smoke and static electricity, helps control odors, and acts on mold, bacteria and viruses in the coil and the living space. Those are the manufacturer's claims, and the tests behind them follow.

It works in any residential duct air conditioning system up to six tons in size. It can be installed either inside or outside of the ducts, or near the indoor fan in the air handler. Nu-Calgon states that the unit needs no maintenance or replacement parts, so there is nothing to swap out each season.

What the manufacturer's lab tests report

These figures are Nu-Calgon's published laboratory results, not a promise from R.A. Heating. In one test, run with the iWave-C unit under conditions meant to mimic an aircraft fuselage, 84.25 percent of the virus was inactivated at 10 minutes and 99.4 percent at 30 minutes.

Nu-Calgon ran a second test in a laboratory chamber with the iWave-R, placing a petri dish with a pathogen under a hood to see how it reacted to ionization over time. The company notes that locations vary, and that clients should evaluate their own application and environmental conditions before judging the technology's potential benefits.
