How to prevent dirt from entering ducts?
To prevent dirt from entering the system: Use the highest efficiency air filter recommended by the manufacturer of your heating and cooling system. Change filters regularly.
Does cleaning air ducts help?
Duct cleaning has never been shown to actually prevent health problems. Neither do studies conclusi vely demonstrate that particle (e.g., dust) levels in homes increase because of dirty air ducts or go down after cleaning. This is because much of the dirt that may accumulate inside air ducts adheres to duct surfaces and does not necessarily enter the living space. It is important to keep in mind that dirty air ducts are only one of many possible sources of particles that are present in homes. Pollutants that enter the home both from outdoors and indoor activities such as cooking, cleaning, smoking, or just moving around can cause greater exposure to contaminants than dirty air ducts. Moreover, there is no evidence that a light amount of household dust or other particulate matter in air ducts poses any risk to health.

How to clean ERV filter?
Using either a shop vac or a household vacuum cleaner, gently remove as much dust and debris from the ERV or HRV filter and core as possible. Set aside the pleated paper core (if applicable) after vacuuming.
Why do ventilators need to be cleaned?
Whole-house ventilators, like air exchangers, energy recovery ventilators (ERV) and heat-recovery ventilators (HRV) need routine cleaning because the air pulled into these units carries a build up of dust and debris with it — creating a not-so-ideal situation for your air quality. Air exchangers, ERVs and HRVs contain air filters to trap larger contaminants, but some of the dust slips through and settles inside the core, which directs airflow in very specific patterns to facilitate proper ventilation, heat exchange and/or humidity control. Because of this, the core needs to be removed and cleaned on a regular basis, as do other parts in the whole-house ventilation system.
How to clean a ventilator core?
Alternatively, soak the core and filters for a couple of hours in water mixed with a dab of mild soap. After soaking in soapy water, give the filters a final rinse with clean water. Let each piece air dry completely, as installing wet filters or cores into the ventilator can damage it. Accelerate drying by gently shaking off excess water.

Causes
Results
- Some research suggests that cleaning heating and cooling system components (e.g., cooling coils, fans and heat exchangers) may improve the efficiency of your system, resulting in a longer operating life, as well as some energy and maintenance cost savings. However, little evidence exists that cleaning only the ducts will improve the efficiency of the system.
Prevention
- You may consider having your air ducts cleaned simply because it seems logical that air ducts will get dirty over time and should be occasionally cleaned. Provided that the cleaning is done properly, no evidence suggests that such cleaning would be detrimental. EPA does not recommend that the air ducts be cleaned routinely, but only as needed. EPA ...
Summary
- Duct cleaning generally refers to the cleaning of various heating and cooling system components of forced air systems, including the supply and return air ducts and registers, grilles and diffusers, heat exchangers heating and cooling coils, condensate drain pans (drip pans), fan motor and fan housing, and the air handling unit housing (See diagram).
Issues
- If not properly installed, maintained and operated, these components may become contaminated with particles of dust, pollen or other debris. If moisture is present, the potential for microbiological growth (e.g., mold) is increased and spores from such growth may be released into the home's living space. Some of these contaminants may cause allergic reactions or other …
Benefits
- Knowledge about the potential benefits and possible problems of air duct cleaning is limited. Since conditions in every home are different, it is impossible to generalize about whether or not air duct cleaning in your home would be beneficial.
Risks
- If no one in your household suffers from allergies or unexplained symptoms or illnesses and if, after a visual inspection of the inside of the ducts, you see no indication that your air ducts are contaminated with large deposits of dust or mold (no musty odor or visible mold growth), having your air ducts cleaned is probably unnecessary. It is normal for the return registers to get dusty …
