Clorox 20x25x1 Air Filter MERV 13 Pleated - Pack of 4

Our review of the Clorox 20x25x1 Air Filter (pack of 4) finds it is a practical choice for homeowners and small offices that need reliable, longer-lasting filtration without fragrances. The biggest reason to buy is its MERV 13 pleated media, which captures a wide range of indoor particles while offering up to 90 days of service per filter depending on use. Installation is straightforward and the unscented, synthetic media makes these filters suitable for spaces sensitive to smells.

Key Features

• Designed to fit: The filters are manufactured to the nominal 20x25x1 size with an actual size of 19.75in x 24.75in x 0.75in for a snug, drop-in replacement in compatible housings.
• MERV 13 performance: The pleated media captures finer particles than standard filters and is comparable to MPR 1500 & FPR 10 for improved indoor air cleanliness.
• Long-lasting: The pleated design is rated for up to 90 days of filtration under typical use, reducing replacement frequency versus basic fiberglass filters.
• Durable construction: A premium beverage board frame and wire-backed media deliver structural integrity and reliable performance across the filter life.
• Unscented media: The filter is completely unscented, making it a safer choice for sensitive occupants and scent-free environments.
• Easy installation: The filter frame includes an airflow direction indicator to help align and install the filter quickly and correctly.

Who It's For

The Clorox 20x25x1 MERV 13 filter is best for homeowners, small office managers, and school maintenance staff who want improved particle capture and longer intervals between changes compared with basic fiberglass filters. It suits spaces where unscented filtration and structural durability are priorities, such as classrooms, bedrooms, and common living areas.

It is less suitable for specialty needs like HEPA-level filtration or systems that require a different physical thickness or non-standard dimensions; users needing HEPA or medical-grade filtration should look for higher-rated or purpose-built options.
