Comparative Tests on Pressure Drop of HVAC Filters

We test 20 filters for pressure drop and efficiency. It is often very difficult to compare pressure drop for HVAC air filters. Even though filter tests are standardized it is not unusual for the same type of filter to be tested in two different laboratories with two different results. In addition, filter tests are run … More

Sorting Fact from Fiction on Health Effects of Mould

Leading Asthma and Allergy Experts Discuss the Most Recent Scientific Evidence on Health Effects of Mould Several years ago I had the pleasure of attending a joint meeting of the National Air Filtration Association and the Indoor Air Quality Association. One of the key speakers was Dr. Michael Rinaldi of the University of Texas Health … More

What is a Safe Level of Ozone for an Air Cleaner?

The Consumer Product Safety Commission (CPSC) is trying to answer this question. Their study and the responses to that study highlight the complexity of the issue. As the sales of air cleaners have increased over the past 10 years a serious question has been raised about products that generate ozone as a byproduct. What level … More

Study Finds RCI Devices Increase Indoor Ozone and Are Relatively Ineffective at Particle Removal

This study shows that the RCI (radiant catalytic ionization) Air Cleaning Devices produce fairly significant levels of ozone and are less effective than a standard air filter at removing 2 micron sized particles. Researchers at the University of Cincinnati have found that the RCI “air cleaning device” produces a significant amount of ozone and is … More

Improving Indoor Air Quality in Classrooms Leads to Higher Test Scores

This study shows that improved indoor air quality in classrooms leads to higher test scores for students. Education budgets are tight. Politicians are busy putting limits on school budgets to “put more money in the classroom.” The problem is – if you do not provide safe, healthy and encouraging environments, it does not matter how … More

Studies Show Improved IAQ Leads to More Productivity

Numerous studies show that improving the Indoor Air Quality will lead to higher worker productivity. Measures to improve IAQ don’t cost – they pay!! In a recent article presented by the U.S. Green Building Council and Building Operating Management David P. Callan did an excellent job of summarizing the studies that have been done in … More

The Indoor Air Thickens – New Study Confirms Links with Ozone, Cleaning Agents and Air Contaminants

Fine particles, formaldehyde and other air contaminants are created when common cleaning agents are exposed to indoor ozone. When used indoors in the presence of ozone, many household cleaners and air fresheners emit toxic pollutants at levels that may lead to health risks according to a new study by researchers at the University of California, … More

Isn’t it Ionic? Air Purifiers Make Smog

Another study confirms that ionizers and ozone generators can create unhealthy levels of ozone in poorly ventilated rooms. The news does not appear to be getting any better for ionizers, ozone generators or other devices that generate ozone and claim to be “air purifiers.” Another study has raised additional concerns about these devices. This study … More

Do Air Filters Provide Health Benefits?

Air cleaners and air filters alone have not been shown to be clinically effective at reducing allergy symptoms. Last Friday (March 31) I was very fortunate to be able to participate in a round table discussion on indoor air research. This meeting was conducted by university indoor air scientists and engineers and was attended by … More
