Filter King 29x17x1 Air Filter 4-Pack - MERV 8 Pleated HVAC Filters

Our review of the Filter King 29x17x1 4-pack finds it best suited for homeowners and renters who want an affordable, reliably sized replacement air filter that balances particle capture and airflow. The single biggest reason to buy is simple: these are MERV 8 pleated filters that are fully manufactured in the USA and designed to trap common household particles without noticeably restricting HVAC performance. For people replacing 1 in filters on a 30 to 90 day schedule, this pack is a practical, no-frills choice.

Key Features

• MERV 8 rating: Provides effective filtration of household dust and pollen while maintaining adequate airflow for most A/C and furnace systems.
• Actual size: Labeled 29 in x 17 in x 1 in with an actual depth of 0.75 in, so users should check their slot for a slightly under 1 in fit.
• Made in USA: Fully manufactured domestically, offering consistent construction and traceable production (EPA Establishment Number provided).
• Pleated design: The pleats increase surface area to capture more particles and extend filter life between replacements.
• Up to 90 day life: Rated for up to 90 days depending on household conditions, giving flexible replacement intervals from 30 to 90 days for 1 in applications.
• Easy installation: Simple open, slide and close installation makes swapping filters quick for most homeowners.

Who It's For

This filter pack is ideal for homeowners, renters, and small-business operators who need a dependable, budget-friendly replacement for standard 1 in HVAC filter slots and who prioritize balance between particle capture and system airflow. It fits those who replace filters seasonally or on a 30 to 90 day cycle and want a pleated MERV 8 option made in the United States.

People who should look elsewhere include households requiring higher-efficiency filtration for severe allergies or medical needs, or anyone whose system requires a full 1 in thickness rather than the slightly thinner 0.75 in actual depth; double-check sizing if your slot is tightly toleranced.

Pros & Cons

Pros
