Why customers choose TaskHolt Tools

Keep your home’s air crisp and inviting with Filtrete’s 17.5x23.5x1 air filter. The actual size is 17.18 x 23.18 x 0.81 inches, designed to fit standard 17.5x23.5x1 frames. Built with exclusive Filtrete 3-in-1 technology, this filter combines a MPR 1000 rating with MERV 11 filtration, aiming to pull in and trap a wide range of particles while letting cleaner air pass through smoothly.

What makes this filter stand out is the balance it offers between filtration and airflow. A 4-pack provides coverage for a 3-month replacement cycle, helping you maintain a steady flow of air in your furnace, air conditioner, or HVAC system. The combination of particle capture and consistent airflow can contribute to a fresher, more comfortable living space without sacrificing performance from your HVAC equipment.
