Clorox Air Filters 18x18x1 Furnace Filter - MERV 13 Performance

Our review of the Clorox Air Filters 18x18x1 finds it best suited for homeowners and small offices that need reliable, higher-efficiency particulate capture without fuss. The single biggest reason to buy is the MERV 13 filtration, which is comparable to MPR 1500 and FPR 10 and captures a wide range of indoor particles while remaining easy to install. The pleated design and synthetic electrostatically charged media promise longer service life than basic fiberglass filters, making this a practical choice for routine HVAC maintenance where cleaner indoor air is a priority.

Key Features

• Designed to fit: Actual filter size is 17.75in x 17.75in x 0.75in, intended to replace 18x18x1 slots with a snug fit for reliable sealing.
• MERV 13 media: Captures a wide range of unwanted indoor particles and is comparable to MPR 1500 and FPR 10 for stronger filtration performance.
• Pleated construction: The pleated design increases surface area to provide up to 90 days of filtration performance depending on use, extending service intervals versus flat fiberglass options.
• Electrostatic synthetic media: The charged media is engineered to improve particle capture efficiency while maintaining airflow through the HVAC system.
• Durable frame: Premium beverage board frame and wire-backed media provide structural integrity so the filter keeps its shape during use and handling.
• Unscented: The filters are unscented, making them suitable for spaces or occupants sensitive to added fragrances.

Who It's For

This Clorox 18x18x1 filter is aimed at homeowners, landlords, and small office managers who want improved indoor air quality without changing filters frequently; the up to 90 day service life and higher-efficiency MERV 13 rating make it a practical upgrade over basic disposable fiberglass filters. It also suits classrooms and healthcare-adjacent spaces where reducing airborne particles matters.

Those who should look elsewhere include users with HVAC systems that require a different thickness or exact 18.0in sealed-frame hardware; always confirm the actual 17.75in x 17.75in x 0.75in dimension fits your filter slot. Also, highly specialized cleanroom or medical facilities needing certified HEPA-level filtration will need a different product.

Pros & Cons

Pros

• Pleated, electrostatically charged media offers longer filtration life and improved particle capture.
• Durable beverage board frame and wire backing help maintain shape and installation ease.
