Aerostar 18x18x1 MERV 8 Pleated Air Filter | 6 Pack | Actual Size 17.5 x 17.5 x 0.75 in | Made in USA

Cleaner indoor air starts with a reliable filter

Aerostar 18x18x1 MERV 8 pleated air filters are designed for standard 1-inch filter slots, and they come in a convenient six-pack. The actual size is 17.5 x 17.5 x 0.75 inches, ensuring a precise fit for many residential and light commercial HVAC setups. With this size accuracy, you’ll experience straightforward installation and consistent filtration today and for the weeks ahead.

The filtration tech uses electrostatically charged synthetic media to trap particles in the 0.3 to 1.0 micron range, including lint, dust mites, spores, and pollen. While this is not medical guidance, many users notice less visible dust in rooms and a sense of refreshed air after a filter change, especially during busy allergy seasons.

In everyday living, these filters can support cleaner air during periods of heavy use, such as when windows stay shut or during high-traffic months. They are designed to help keep airflow steady, which may reduce strain on the HVAC system and keep performance steady as temperatures swing.

• UNIVERSAL COMPATIBILITY: Fits most standard 1-inch filter slots in residential and light commercial systems; actual size helps ensure a snug seal.
• DEPENDABLE MERV 8 FILTRATION: Captures up to 90% of airborne particles like dust, pollen, pet hair, and mold spores.
• ENHANCED AIRFLOW & EFFICIENCY: Pleated media traps more particles while preserving smooth airflow, supporting steady system performance.
• LONG-LASTING, DURABLE DESIGN: Heavy-duty beverage board frame with moisture-resistant backing and reinforced pleats for up to 3 months of use.
• PROUDLY MADE IN THE USA: Manufactured in American facilities with quality materials for dependable, cleaner indoor air.

Maintenance tip: For best results, replace every 60 to 90 days. In peak summer and winter months, consider changing every 30 days to maintain filtration and efficiency. This simple step helps you sustain air quality and HVAC performance without overloading the unit.

Compatibility, performance, and value come together in this six-pack from Aerostar. If you’re upgrading from fiberglass filters or switching to a higher-efficiency pleated option, these filters offer a straightforward, cost-effective path to potentially crisper indoor air and smoother system operation.
