Simply 18x18x1 Air Filter MERV 8 — 6 Pack (17.75x17.75x0.75) Pleated for Dust & Pet Dander

Simply 18x18x1 MERV 8 air filters (six-pack) are pleated HVAC filters sized 17.75" x 17.75" x 0.75" that capture common household particles to improve indoor air quality.

These six pleated filters are designed for straightforward replacement in most residential and light-commercial furnaces, air conditioners, and HVAC return grilles. Built with a denser media and a higher pleat count than many retail options, they balance particle capture with steady airflow. Each filter is shrink-wrapped for clean delivery and made in the USA from domestic components.

How well will these filters remove dust, pet dander, and pollen?

The MERV 8 rating makes these filters effective at trapping larger airborne contaminants like dust, lint, pet dander, and pollen without overly restricting airflow. They are a practical choice for homes that need routine particle control rather than specialized fine particle filtration.

• Removes common particles such as dust, pet hairs, and pollen
• Higher pleat count increases surface area for better capture
• Balances filtration with system airflow to protect HVAC components

Will these fit my existing HVAC or furnace?

Each filter measures an actual 17.75" x 17.75" x 0.75", intended for slots labeled 18" x 18" x 1"—a common residential size. They are compatible with most brands and central system designs; simply follow the airflow arrows when installing.

• Actual dimensions match standard 18x18x1 housings
• Works in furnaces, air conditioners, heat pumps, and return grilles
• Easy slide-in installation; no tools required

How long will each filter last and how should I maintain them?

Each unit provides reliable performance for up to three months under typical household conditions; homes with heavy pet hair or high dust may need more frequent changes. Inspect monthly and replace sooner if visibly dirty or if airflow drops noticeably.

• Recommended replacement interval: up to 3 months
• Check monthly in high-use or high-dust environments
• Dispose of used filters in normal waste; replace with fresh unit from the pack

What makes Simply filters different from other retail brands?

Simply filters use a tighter pleat arrangement to increase filtration surface area while maintaining adequate airflow for most residential systems. They’re manufactured in the USA from domestic parts and arrive individually shrink-wrapped to stay clean until installation.

• Higher pleat count than many store-brand filters for increased capture
• Heat-sealed packaging to prevent shipping dust and germs
• Made in the USA using 100% American components
