BNX TruFilter MERV 13 Air Filter 20x20x1 6-Pack — Electrostatic Media, Low Airflow Resistance

BNX TruFilter 20x20x1 is a MERV 13 electrostatic HVAC filter sold in a 6-pack that fits standard 20x20x1 housings and captures fine particulates like pollen, pet dander, smoke and other microscopic contaminants.

Designed and manufactured in the USA by BNX Converting, LLC, this 6-pack of TruFilter filters delivers high-efficiency filtration while keeping airflow resistance low. Each filter is built to an actual size of 19.68" x 19.68" x 0.75" to fit common 20x20x1 slots, and uses electrostatically charged media and a single-piece recycled cardboard frame for reliable performance and reduced environmental waste. The media rates MERV 13—comparable to MPR 1500/1900 and FPR 10—making it suitable for homeowners seeking stronger capture of fine particles without sacrificing system efficiency.

How does this filter improve indoor air quality?

The MERV 13-rated media captures a wide range of airborne particles, including pollen, pet dander, dust, smoke and many microscopic carriers that lower-rated filters miss. Electrostatic charge helps attract and hold tiny particles while the design maintains low airflow resistance so HVAC systems run efficiently.

• Removes up to 98% of targeted airborne particles in its rating range
• Electrostatically charged fibers enhance capture of fine particulates
• Compatible with most residential furnaces and air conditioners sized for 20x20x1

Will it fit my HVAC system and how is the actual size measured?

Although commonly labeled 20x20x1, BNX lists the true dimensions as 19.68" x 19.68" x 0.75" to reflect the real filter thickness and ensure a proper fit in standard frames. Always check your unit's filter slot orientation and airflow arrow before installation for the correct fit and performance.

• Actual size: 19 11/16" x 19 11/16" x 3/4"
• Labeled to replace filters rated MPR 1500–1900 and FPR 10
• Fits typical 20x20x1 housings in furnaces and air conditioners

How long do these filters last and how often should I change them?

Filter life depends on household conditions: homes with pets, smokers, or high dust will need more frequent changes. In general residential use, replace MERV 13 filters every 1–3 months; check monthly to determine the right cadence for your environment.

• Inspect monthly for visible buildup or reduced airflow
• Replace sooner in homes with pets, allergies, or heavy pollution
• Six filters in the pack support routine replacements across seasons

What makes BNX TruFilter different from basic fiberglass filters?

Unlike basic fiberglass panels that mainly stop larger particles, BNX TruFilter uses advanced electrostatically charged media that captures much smaller airborne contaminants while still preserving airflow. The one-piece recycled cardboard frame and UL 900 classification reflect manufacturing standards and durable construction.

• MERV 13 media captures finer particles than standard fiberglass filters
• Lower airflow resistance helps maintain HVAC efficiency
• Manufactured in Houston with sustainable frame technology

Who is this for: BNX TruFilter 20x20x1 is aimed at homeowners and renters who want stronger particulate capture than basic filters—especially those with allergies, pets, or concern about smoke and fine dust—who also need a reliably sized filter that fits common 20x20x1 slots. It's suitable for anyone seeking American-made filters with MERV 13 performance in a convenient 6-pack for scheduled replacements.
