Clorox 20x20x1 Air Filter MERV 13 Pleated Pack of 4 - Long Lasting

In this review the Clorox 20x20x1 Air Filter is evaluated for homeowners and small offices seeking higher-efficiency furnace filtration without complicated installation. The bottom line: this four-pack of pleated MERV 13 filters is best for people who want noticeably cleaner indoor air for up to 90 days per filter, with a sturdy frame and electrostatically charged media that capture fine particles. The reviewer found the filters straightforward to install and effective at reducing airborne dust and allergens compared with basic fiberglass options.

Key Features

• Designed to fit: The replacement filters have an actual size of 19.75 in x 19.75 in x 0.75 in so they slide into standard 20x20x1 slots with minimal trimming or adjustment required.
• MERV 13 performance: The media is rated MERV 13 and is comparable to MPR 1500 and FPR 10, which helps capture finer indoor particles that lower-rated filters miss.
• Pleated for longevity: The pleated construction is intended to deliver up to 90 days of filtration depending on use, giving longer service between changes than many fiberglass filters.
• Electrostatically charged media: The synthetic charged media improves particle capture while maintaining airflow suitable for most residential furnace and HVAC systems.
• Sturdy construction: A premium beverage board frame and wire-backed media provide structural integrity so the filter holds shape during use and handling.
• Unscented for sensitive spaces: These filters are completely unscented, making them appropriate for households, classrooms, and offices where fragrances are a concern.

Who It's For

The Clorox 20x20x1 MERV 13 filter is ideal for homeowners, apartment residents, and small offices that want a step up in particle capture without changing furnace or HVAC hardware. It suits anyone who wants longer-lasting pleated filtration for dust, pollen, pet dander, and other common indoor particles.

Those who need specialty gas or odor removal, HEPA-level filtration for severe respiratory conditions, or nonstandard filter sizes should look elsewhere; this product is focused on particulate capture with a standard 20x20x1 form factor rather than chemical adsorption or absolute HEPA performance.
