Purifying the Air in Your Home

Using HVAC Purifying Equipment and Filters

Written by: Lorelei Bucarey

Many of us would like to improve the air quality in our homes.  Perhaps it’s because of the weather and your windows are kept closed, or perhaps it’s because the weather is nice and all your windows are open, allowing allergens inside.  Or maybe even you have little allergens family members living in the house like a beloved cat, dog or bird.  Or maybe even the ones we don’t see or think about but exist, dust mites and their feces.  None are very nice to think about but all may have an effect on our health.  With all the pollution outside sometimes we don’t think about the air quality right in our own homes which can have a big effect on our health and quality of life.  Even if you do a wonderful job keeping your home clean there are things you just can’t control by yourself.  This is when one has to think about their HVAC systems because sometimes your Air Conditioning system just isn’t enough.  Although this will filter the air the good news is there are other forms of HVAC Air Conditioning and Filtering systems and equipment that can help us to augment the quality and purity of our air.

Air Purifiers can help us do just that.  Below is a list of all the things an AIR Purifier HVAC system and or equipment can help you to filter out of the air in your home:


We can use these air purifiers to reduce the concentration of these airborne contaminants and though very useful for people who suffer from allergies and asthma[, technological and scientific studies are finding that poor air quality is a contributing factor of some forms of cancer, respiratory illnesses, COPD, and other pulmonary infections and illnesses. They also do a great job at reducing the need for frequent room and area cleaning.  Air purifiers use a small amount of electrical energy, causing a small amount of expense and environmental effect.


Below is a list of the various Air Filtering and Purifying techniques:



UVGI (Ultraviolet germicidal irradiation)  can be used to sterilize air that passes UV lamps via forced air.  This form of sterilization uses the placement of the UV lamps as well as a good filtration system to remove the dead micro-organisms


Filter based purification traps airborne particles by size exclusion. Air is forced through a filter and particles are physically captured by the filter.   HEPA filters remove at least 99.97% of 0.3-micrometer particles, and are usually more effective for particles which are larger or slightly smaller.  


Activated carbon is a porous material that can absorb volatile chemicals on a molecular basis, but does not remove larger particles.


Photocatalytic Oxidation (PCO)' is an emerging technology in the HVAC industry.   In addition to the prospect of IAQ benefits, it has the added potential for limiting the introduction of unconditioned air to the building space, thereby presenting an opportunity to achieve energy savings over previous prescriptive designs.


Ionizer purifier’s use charged electrical surfaces or needles to generate electrically charged air or gas ions. These Ions attach to airborne particles which are then electrostatically attracted to a charged collector plate.


In September, 2007, the California Air Resources Board announced a ban of in-home ozone producing air purifiers. This law, which will take effect in 2009, will require testing and certification of all types of air purifiers to verify that they do not generate excessive ozone.


In conclusion I hope this helps you make informed choices in the usage of your home HVAC equipment and air purifying choices.  We will be keeping this information updated with any upcoming HVAC related news pertaining to the health and air quality in your home.
