Purifox LLC

Purifox LLC operates as an air duct cleaning specialist serving Alexandria, Falls Church, and surrounding Northern Virginia communities from its base in Alexandria. With a 4.8-star average drawn from 929 customer reviews, the company has built a reputation for methodical ductwork and dryer vent sanitation over nearly a decade in operation. The licensed contractor handles both residential and commercial properties, offering chimney sweeping and carpet cleaning as complementary services. Property owners across Fairfax, Arlington, and Prince William counties have entrusted their indoor air quality to this team, which maintains a six-month workmanship warranty on completed services.

What distinguishes Purifox from competing duct cleaning services is its commitment to transparent documentation. Technicians capture before-and-after imagery of cleaned ductwork, giving customers visual confirmation of results. The company backs every job with a six-month customer warranty, reflecting confidence in their cleaning standards. Beyond standard air duct sanitation, the team addresses chimney flues and dryer ventilation systems, areas where neglected maintenance poses fire risk. This multi-disciplinary approach lets homeowners coordinate HVAC, chimney, and venting maintenance through a single service call.

Customer feedback consistently highlights specific team members who exceed expectations. A reviewer described technicians Myinor and Axel arriving at a residence, explaining the cleaning process while demonstrating respect for the living space. The same pair provided personalized recommendations for homes with pets, noting how animal dander accelerates duct contamination. Another client praised the team for thorough explanations of coil and filter cleaning, with the reviewer noting immediate improvements in air freshness and cooling efficiency after service completion.
