Simply 18x18x1 MERV 8 air filter six-pack delivers reliable dust, pet dander, lint, and pollen capture for cleaner indoor air in residential HVAC systems.

These pleated filters from Simply are sized to work with most home and light-commercial HVAC units (actual filter dimensions: 17.75" x 17.75" x 0.75") and come in a convenient six-pack.

How do Simply MERV 8 filters improve everyday indoor air?

MERV 8 filtration targets common household airborne particles without overly restricting airflow in central systems. These filters reduce visible dust and many allergens by trapping particles like pollen, pet dander, and lint, helping equipment run efficiently between changes.

• Captures a broad range of particulates common to homes and offices.
• Pleated media increases surface area for longer service life.
• Maintains airflow suitable for most residential furnaces and ACs.
• Recommended replacement interval up to three months under typical conditions.

Will these filters fit my HVAC or furnace return?

Yes — the nominal label 18" x 18" x 1" corresponds to an actual filter size of 17.75" x 17.75" x 0.75", which is compatible with most brands and standard slots. Simply designed these to be a drop-in replacement for many retail name-brand sizes.

• Actual dimensions suit standard 18" filter openings.
• Works with common systems including air conditioners, furnaces, heat pumps, and return grilles.
• Comparable to popular retail alternatives for easy cross-reference.
• Insert following the airflow arrow; typically slides into the existing filter slot.

How long does each filter last and how do I install them?

Under normal household use, each Simply filter is built to perform for up to three months before replacement. Installation is tool-free: open the housing or grille, slide the filter into place aligned with the airflow arrow, and dispose of the old filter responsibly.

• Up to 3 months of effective filtration in average conditions.
• Heat-sealed shrink wrap keeps filters clean until use.
• Simple slide-in installation with clear airflow arrows for orientation.
• Subscription option available to automate timely replacements.

What makes Simply filters different from other retail options?

• Higher pleat count than many retail comparables for increased media area.
• Manufactured in the USA using American components and recycled materials.
• Delivered in heat-sealed wrap to prevent shipping dust contamination.
• Sold as a six-pack to lower per-filter cost and simplify maintenance.

It’s a practical choice for households with pets, seasonal allergies, or anyone seeking regular, easy-to-replace filtration without upgrading to high-restriction media.
