What Happens to the Particles When You Sneeze?
Particles settle out of the air at different rates depending on the size of the particle. These tests show the relative exposure from particles at different distances from the source.
All MERV 8 Air Filters are not Created Equal - Performance Varies Greatly by Particle Size
Different MERV 8 Filters do not perform in the same way on all particle size ranges. Pleated filters have far higher efficiency on medium sized and small sized particles than polyester pads or ring panels.

Using HEPA filters in the home is an easy and accessible way to curb heart disease say researchers.
Asthma and Allergy Foundation of America - Texas Chapter Provides Outstanding Asthma Online Resource
Education is the key to controlling the effects of asthma. The Asthma and Allergy Foundation of America - Texas Chapter website has been enhanced to provide the best resource available on the internet for physicians, nurses, care givers, schools, asthmatics, and the parents of asthmatics.
The Effect of Particle Removal Effectiveness on Particle Levels in an Office Environment
Particle removal effectiveness is a function of filter efficiency and the air exchanges per hour but also of outdoor to indoor particle transfer, particle size and indoor activity.
Are Portable Air Purifiers Effective for Reducing Indoor Allergens?
A study by researchers at Johns Hopkins provides some interesting insight into the use of air purifiers at reducing indoor allergens.
Children in Neighborhoods Near Highways and Railroad Intersections at Risk for Asthma
A study by Mayo Clinic shows that children living near traffic intersections at greater risk of developing asthma.
Study of Particle Counts in School with Mechanical Ventilation Produces Surprising Results
This study shows that a school with mechanical ventilation and a variable volume make-up air system using MERV 8 pleated filters has significant reductions in small particles but lower than expected reductions in particles in the 3 to 10 micrometer range.

Saline Rinse May Cut Cold and Flu Symptoms
Cold medications are out for children. Simple saline rinse could be the answer for quicker recovery from colds and flu.
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
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
Only Filter Certification now open to all individuals interested in air filters and indoor air quality.
Avian Flu Filtration Precautions
Proper filtration can help to minimize the risk of spreading the flu virus.
