PTO PTA Healthy Classroom Air Project

PTO and PTA Groups are searching for school improvement projects that will make a difference.  One of the newest project ideas is cleaning up the air quality in elementary school classrooms.  The potential benefits include all of the following:

  • Fewer student sick days from respiratory infections.  One school documented 61% fewer sick days.
  • Lowering the use of daily allergy medications which have negative side effects.
  • Reduced use of expensive rescue inhalers at school.  Schools documented a 70% reduction.
  • Reduced teacher sick days by 50% and reduced their healthcare costs.  One teacher reported stopping medical treatments saving $600 per month.
  • Fewer sick days, and less use of mind-numbing allergy medicines produce higher test scores on standardized tests.

PTO and PTA groups can go after funding from families, their employers and other sources in their communities who want to help schools make all of these exciting improvements that last for year after year once the classrooms are equipped with these powerful air purifiers.  The number one reason PTO and PTA groups should want to install Purifans in classrooms is to reduce the number of days their child is sick and misses school.  This often causes one of the parents to miss work, and can cost a lot of money in the cost for doctor office visits, medical tests, prescriptions, over the counter medications and daily allergy or asthma medications.

Classroom IAQ Impacts Student Attendance

The main reason employers and families will be motivated to raise the money needed for this PTO project is the potential payback in financial savings, reduced sick days and a boost in average test scores.  In the school above the average student missed 11 fewer sick days in the first school year after Purifans were installed.  This school building had a history of air quality issues with hidden mold from water damage and age.  So sick days where averaging 10% per year.  The cost of a sick day is getting more expensive every year.  With new health insurance plans having higher co-pays, higher deductibles and reduced coverage these costs can place a tremendous burden on families and employers.

Classroom Air Quality Can Increase Health Costs

A school building with fewer IAQ problems than the exampe above should also see a reduction sick days for both students and teachers if classroom air purifiers are installed.  In the Howard Elementary School, teachers reported 50% fewer sick days.  The nurses station actually recorded a 70% decrease in inhaler use in the first year after the Purifans were installed in the classrooms.

In any new building or older school building the particles measured in the air are much higher than outside levels on most days.  Many of the offending particulates and allergies that fill the classroom air actually arrive daily on the skin, clothes, coats, hair, backpacks and shoes of the students and teachers.  Some students rolled all over the sofa that was covered in cat dander, prior to heading to school.  These allergens become part of the dust in the classroom that settle on the floor and desk surfaces.  When this dust is stirred up and floats in the air, children breathe in these allergens and trigger all kinds of allergy problems and illnesses.

The other costs are for the employers who have to deal with the lost work product of parents who have to stay home to care for sick children.  This can have a big impact on an employer and also can drive up the costs of healthcare insurance for the employer.  In some cost payback analysis the financial return for this PTO PTA project can exceed 25 times the costs.  And these are real out-of-pocket costs that can be a big savings for the families, teachers, insurance companies and the employers.  Even the students on Medicaid can produce significant savigns for these health programs based on some studies.

The teachers also deserve some serious consideration when this PTA PTO project is being discussed.  A room full of children returning from recess on a warm day can produce an undescribable odor that are very undesirable for the teacher.  Reducing classroom odors, teacher sick days, teacher health costs and coughing children in the classroom can be the best gift you can give any teacher.  After Purifans were installed, some teachers reporting being able to stop allergy treatment programs that were costing them more than $600 per month in out-of-pocket health expenses.

Teachers Complain About Classroom Air Quality

The Purifan company is offering special PTA PTO Pricing Bundles at lower prices to help more schools improve their classroom air quality.  The first year classroom bundle cost can be as low as $968 per classroom for the air purifier systems.  Installation can be provided by the school or parent groups in most ceiling types.  The units install like a normal ceiling fan.  The second year the only cost is replacing the filters at the start of the school year and at the holiday break.  The Purifan company is offering low-cost filter classroom bundle pricing dropping the cost per classroom as low as $168 per school year, or approximately $8.40 per student per year.  If filtering classroom air saves each student just one illness that causes the child to miss two school days, the real out of pocket savings could be worth $600 or more to the family and employer.  You can see that is a substantial financial return on the annual cost of $8.40 per student!

 The EPA posts information on many indoor air quality studies describing the cause, impact and educational costs of classroom IAQ problems.

The powerful ceiling mounted Purifan operates quietly and is constantly moving the air in the classroom.  The airflow pattern pushes the dirty, particle filled air directly under the Purifans where the air is sucked into the spinning Purifans and forced through the five layer .3 micron filters 40 times each hour.  The results can be a substantial reduction in airborne particulates in just a few hours after they are installed.  Here are some comparisons of classroom in the same building with and without Purifans filtering the classroom air.

Classroom Particle Count Reductions

In addition to providing healthier air quality for students and teachers the movement of the air in the room can eliminate hot and cold spots and actually save on the HVAC energy required to heat or air condition the rooms.

Classroom Air Purifiers Save HVAC Energy Costs

There are also cases where the impact of poor classroom air quality has also caused lawsuits for some schools.   Any building with a history of water damage from storms, floods or leaking windows or ceilings, a pipe breaking or toilet over-flowing, can dramatically raise the hidden mold issues and respiratory health issues for the occupants.  The CDC cites studies where respiratory health problems are 300% higher in buildings with a history of water damage.

Here are some typical classroom installations.  The air purifiers are mounted along the centerline of the room about 25% from each end.  This gives the classroom 4 square feet of dedicated five-layer filter media, and moves all the air in the classroom through the filters approximately once every ninety seconds.  Cleaning up airborne particulates quickly can be very important because dust and dangerous allergens settle to the floor and when students enter the classroom from recess or lunch, these partculates are disturbed and rise back into the air quickly.  The nose and mouth of small children are much closer to the floor than adults and these children are forced to inhale these allergens.  Rapidly filtering the air improves the air quickly reducing the impact of this floor dust that rises into the air.  This rapid filtration is also one of the main reasons teachers report such a major improvement in odors in their classroom.  Hot sweaty children can produce a very bad smell when they return from recess activities.
