Air Duct Cleaning and HEPA Filters Help Bring Relief to Allergy Sufferers

The arrival of spring means allergy sufferers will want to retreat indoors.  But while your home is supposed to be a refuge, it also harbours allergy-provoking particulates.  eieihome spoke with Mark Dela Cruz of Dave’s Duct Cleaning, for his tips on reducing allergy triggers in the home.

The president of Dave’s Duct Cleaning has both personal and professional experience with creating a clean home environment.  “His then two-year-old son would regularly have to use his puffer around the home after just minutes of running around,” says Mark Dela Cruz.

Air Duct Cleaning 

Cleaning your HVAC system helps remove impurities that have accumulated over time that can trigger respiratory distress.  There are three common types of air pollutants: particulates such as dust, pollen and pet dander, bioburden such as dead skin cells, mold spores and bacteria, and volatile organic compounds (VOCs) gasses that are emitted from paint or hardwood floor varnish.  Air duct cleaning can remove particulates and some bioburden, but will not eliminate any VOCs as these particles are too small to capture in a regular air duct cleaning service and require a secondary filtration device such as a HEPA (High-Efficiency Particulate Air) filter.


HEPA Filtration 

A HEPA filter works by forcing air through fine mesh that traps particles and is the most effective way to filter the air you breathe indoors to reduce allergy symptoms.  “The biggest difference is the size of the particulates that the filter will capture,” says Dela Cruz.  HEPA filters can capture 99.97% of super-tiny particles up to 0.3 microns in diameter, making the air in the home as pure as possible.

A HEPA filter not only improves air flow in the home, it can also reduce time spent on housecleaning by minimizing the need for dusting.  “The dirty air is no longer settling on the furniture, it’s consistently being unsettled and recaptured as the HEPA filter promotes circulation in the space,” says Dela Cruz.  This also means you don’t need to clean your ducts as often.  Homes with a HEPA filtration system can reduce cleaning frequency to every seven to nine years (rather than the standard five to seven years) provided there are no renovations or pets in the home during that time.

Since taking these steps, Dela Cruz says that Dave has noticed a significant difference in his son’s asthma and allergy symptoms.  “He now runs through the house and doesn’t need his puffer.”
