Why customers choose TaskHolt Tools

Breathable comfort for your home

In busy homes, air can carry dust, pollen, and pet dander. Filtrete’s 17.5x17.5x1 AC Furnace Filter uses electrostatic charge to attract and trap more particles as air moves through your HVAC system, helping to keep indoor air feeling fresher with each cycle.

Why this filter stands out

  • 4-pack designed for a 3-month service life per filter, so you’re rarely left waiting for a replacement
  • MPR 700 rating, equivalent to MERV 8, for targeted particle capture while preserving airflow
  • Electrostatic 3-in-1 technology attracts lint, pollen, dust, and pet dander
  • Non-electrostatic and fiberglass alternatives often underperform in real homes
  • Maintain HVAC performance by changing filters at recommended intervals

Smart features and practical use

  • Filtrete Smart App lets you create a replacement countdown by scanning the packaging barcode
  • Choose 30, 60, or 90 days, with a reminder when it’s time to change
  • Designed to balance filtration with steady airflow through your furnace or air conditioner

Suggestions for real-life use

  • Seasonal pollen boosts in spring and early summer
  • Pet households with shedding and dander
  • High-traffic living areas and rooms prone to dust buildup
  • New HVAC installations or routine maintenance cycles

Quick tips: replace every 90 days for 1-inch filters, and store the 4-pack in a cool, dry place to preserve performance. The actual filter size is 17.19 x 17.19 x 0.81 inches, designed to fit compatible systems while maintaining airflow.
