Simply 14x18x1 Air Filter, MERV 8 — Universal Fit, Made in USA

Cleaner indoor air made simple

Introducing Simply Filters 14" x 18" x 1" MERV 8 air filters, designed to fit a wide range of residential and commercial HVAC systems. With an actual size of 13.75" x 17.75" x 0.75", these pleated filters slide into most return slots with ease, helping maintain fresh air without guesswork.

Why this filter stands out

Our pleated design delivers a higher surface area, which supports better filtration and steady airflow. The filters are made in the USA using 100% American components, reflecting a commitment to quality control and reliable performance. A thicker profile means more filtration capacity and longer life compared to basic, low-density alternatives.

• UNIVERSALLY COMPATIBLE: Works with air conditioners, furnaces, and most HVAC brands; comparable to 3M Filtrete MPR 300/600 and Honeywell FPR 5.
• CREATE A CLEANER ENVIRONMENT: Captures dust, lint, pollen, and pet dander while allowing steady airflow through the system.
• PREMIUM CONSTRUCTION: Electrostatically charged synthetic fibers attract particles without absorbing moisture.

The filter is designed for long-lasting performance—up to about three months under typical home use. When households include kids or seasonal sensitivities, you may opt for more frequent changes to maintain air quality and system efficiency.

• LONG LASTING USAGE: Each filter provides extended life, reducing the frequency of replacements and maintenance tasks.
• EASY TO INSTALL OR REPLACE: Slide into the slot following airflow arrows; no special tools required.
• PACKAGING & SAVINGS: Heat-sealed shrink wrap keeps the filter germ- and dust-free; consider our auto-delivery subscription for convenient restocking.
