Leading Asthma and Allergy Experts Discuss the Most Recent Scientific Evidence on Health Effects of Mould 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. Study on Photocatalytic Oxidation (PCO) Raises Questions About Formaldehyde as a Byproduct in Indoor Air
Research at Lawrence Berkeley National Laboratory finds that Photocatalytic Oxidation (PCO) reduces indoor VOC's but could produce formaldehyde as a byproduct. 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. 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. Study Shows Increased Inflammation in Asthmatics Exposed to Air Pollution
Fine particles in air pollution shown to increase nasal inflammation in asthmatic children. 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!! 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. 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. Do Air Filters Provide Health Benefits?
Air cleaners and air filters alone have not been shown to be clinically effective at reducing allergy symptoms. Alchemy, Indoor Air and the Black Box
Be wary of excessive marketing claims for products to take care of indoor air. Free Radicals Are NOT "Friendly Oxidizers"
Some new air cleaning devices are using free radicals or Reactive Oxygen Species (ROS) to "oxidize" indoor air. Free radicals have been shown to be damaging to human health. Testing is lacking on the by-products of the reactions between free radicals and the components of indoor air. NAFA Expands Air Filter Specialist Program
