Simply MERV 13 20x20x1 Air Filter 6-Pack — 19.75x19.75x0.75 in, Pleated High-Capture for Dust & Allergens

Simply 20x20x1 MERV 13 air filters (6-pack) are pleated HVAC filters built to capture a wide range of airborne particles while fitting standard 20"x20" filter slots.

These replacement filters from Simply come as a six-pack with an actual carded size of 19.75" x 19.75" x 0.75", engineered for use in home furnaces, air conditioners, heat pumps and most residential HVAC return grilles. Rated MERV 13, they are designed to balance particle capture and airflow, using a dense pleated media and higher pleat count than many retail brands. Packaged in heat-sealed shrink wrap, each filter arrives clean and ready to install.

How will Simply MERV 13 filters affect indoor air quality?

MERV 13 media is effective at trapping fine particles that typical lower-rated filters miss, such as pollen, pet dander, smoke particles and many bacterial-sized particulates. While not a medical device, these filters can reduce visible dust and common allergen loads in living spaces when used consistently and changed on schedule.

• Captures a broad range of particles including dust, pollen, pet dander and smoke
• Denser pleated design increases surface area for particle capture
• Helps reduce dust buildup on HVAC components and home surfaces
• Best used with regular replacement every 1–3 months for steady performance

Does this filter fit my system and how do I install it?

The pack is sized to fit standard 20"x20" filter housings; the true dimensions are 19.75" x 19.75" x 0.75", so it slides into most residential filter slots and return grilles without trimming. Installation is typically a one-step slide-in: align the arrow with the system airflow direction and slide it into place.

• Actual size: 19.75" x 19.75" x 0.75" to fit common 20x20 housings
• Follow the printed airflow arrow toward the furnace or air handler
• Suitable for furnaces, central air units, heat pumps and return vents
• Heat-sealed packaging keeps filters clean until use

How long will each Simply filter last and when should I replace them?

Performance depends on home conditions — pets, occupants, and outdoor pollution — but these filters are designed for up to three months of typical residential use. Check the filter monthly; replace sooner if it looks visibly dirty, airflow is reduced, or homeowners have strong allergy concerns.

• Designed for up to 3 months under normal household conditions
• Homes with pets or heavy dust may need 1–2 month changes
• Regular replacement maintains airflow and HVAC efficiency
• Available in six-pack quantity to cover multiple replacement cycles

What makes Simply filters different from other retail brands?

Simply emphasizes a higher pleat count and American-made components, producing a dense but breathable filter media that seeks to improve capture area without overly restricting airflow. The filters are comparable in application to popular retail options but come as a six-pack with attention to packaging and U.S. sourcing.

• Higher pleat count than many store-brand filters for more capture surface
• Manufactured in the USA using 100% American components
• Heat-sealed packaging to prevent dirt during shipping and storage
• Compatible with many leading retail filter specifications

Who is this for? Homeowners and renters who want stronger particulate control than basic fiberglass filters, families with pets or seasonal allergies looking to reduce dust and dander, and anyone who prefers American-made HVAC supplies. These filters suit typical residential systems where a balance of filtration efficiency and maintained airflow is desired; consult your HVAC technician for placements in systems with special air-quality requirements.
