Once you’ve had the air ducts in your home professionally cleaned, implementing a proper air filtration system can help maintain the benefits of that cleaning. Air filters capture contaminants circulating through your HVAC system before they can re-enter your ductwork, preventing the buildup of dust, dander, mold and other particles that threaten indoor air quality. By choosing and maintaining the right air filters, you can prolong the effects of your duct cleaning and optimize healthy air in your home.
Make HVAC Filters a Priority
First and foremost, install new filters after duct cleaning. Given how much debris remove from your ducts during the cleaning process, your existing filters are likely saturate. New filters will allow your HVAC system to function optimally from the start. Then, prioritize regular filter replacements going forward. The minimum recommendation is to replace filters every 3 months, though higher-quality filters may only last 6-12 months. Mark your calendar as a reminder.
Upgrade to Higher Efficiency Filters
Next, consider upgrading your HVAC filters to a higher efficiency rating. Standard filters are labeled Minimum Efficiency Reporting Value or MERV 1-4. Higher MERV 7-13 filters capture smaller particles, including those that cause allergies and asthma. Aim for at least MERV 8 after duct cleaning to keep contaminants out of the air your family breathes.
Use Pleated Filters for Maximum Surface Area
Look for filters with pleated designs for maximum surface area and particle capturing ability within the same physical dimensions. The folds in pleated filters essentially multiply the amount of media that particles must pass through, vastly improving contaminant capture rates. However, pleated filters require more air resistance to push air through all those folds, so confirm that your HVAC system can accommodate them.
Consider Electronic Air Cleaners
For the highest level of air purification, consider adding electronic air cleaners to your HVAC system. These devices use an electric charge to capture particles as small as 0.3 microns, including toxins, odors, smoke and VOC gases. Electronic air cleaners install in series with your existing filters and should not impact the basic functionality of your HVAC equipment.
In summary, proper air filtration after air duct cleaning helps sustain the benefits of that process moving forward. By choosing and routinely replacing higher efficiency and more specialized filters, you can ensure that contaminants aren’t reintroduced into your ducts and air supply after they’ve been so thoroughly cleaned.
