Unfiltered airborne contaminants and frame collapse under high air velocities lead to sudden pressure spikes and perimeter leaks in commercial air handlers. Designed specifically to solve rectangle-track mounting and humidity issues, the 16x25x1 Beverage Board Pleated Air Filter MERV 8 establishes a rugged pre-filtration layer that protects system airflow.
Rectangular Frame Precision Fitting: Engineered for exact 16×25-inch mounting channels, eliminating edge gaps and air leakage commonly found in rectangular air handler tracks.
Hydrophobic Beverage Board Protection: Premium water-impervious board construction prevents frame softening and bowing in moist intake environments under continuous suction.
Targeted MERV 8 Dust Retention: Efficiently captures 3.0 to 10.0-micron particulates—such as dust, pollen, and textile fibers—before they reach secondary filter stages.
Aerodynamic Airflow Optimization: Uniform pleat spacing lowers static pressure differentials, allowing fans to run smoothly while extending replacement intervals.

Maximized Dust Holding Capacity (DHC)
Featuring a 16″ x 25″ rectangular profile with a 400 sq. in. face area, this 16x25x1 Beverage Board Pleated Air Filter leverages advanced V-pleat geometry to significantly expand total media surface area. The increased filtration surface area provides superior dust holding capacity, extending service life and reducing routine replacement frequency.
Heavy-Duty Moisture & Deformation Resistance
Constructed as a durable 16x25x1 moisture-resistant cardboard filter, the high-density frame delivers outstanding structural integrity under harsh conditions. It effectively resists water vapor and high humidity, preventing frame softening, sagging, or buckling even in 80%+ relative humidity or high-velocity airflow environments.
Precision Fit for Rectangular Slots
As a precision-engineered 16x25x1 1 inch MERV 8 filter with exact actual dimensions of 15.5″ x 24.5″ x 0.75″, it provides a snug, bypass-free fit inside narrow rectangular ductwork and side-access filter housings. This precise seal prevents unfiltered air bypass around the frame edges, ensuring complete HVAC system protection.

The 16x25x1 Beverage Board Pleated Air Filter is engineered for high-performance primary filtration in demanding operational environments where standard paper-frame filters fail. Featuring an elongated 16″ x 25″ rectangular profile and high-density, moisture-impervious beverage board construction, it is specifically specified for the following specialized HVAC scenarios:
High-Humidity & Coastal Intakes: Ideal for coastal RTUs, fresh air intakes, and humid environments. The moisture-impervious beverage board resists saturation, preventing frame collapse in 80%+ RH conditions.
Side-Access Rectangular Slots: Precision-engineered (15.5″ x 24.5″ x 0.75″) for narrow 16″ x 25″ AHU tracks, allowing smooth sliding and a perimeter-sealed fit without edge crushing.
High-Velocity VAV Systems: High-density board walls backed by metal grid reinforcement withstand high face velocities and variable airflow without bowing or deforming.
Wet-Process Industrial Ventilation: Perfect pre-filtration for paint booth intake, food processing, and washdown zones, handling moisture and heavy dust loads without structural failure.
Facilities management teams should adjust replacement schedules based on ambient humidity, air velocity, and dust loading conditions:
Standard Commercial Operations: In general office buildings, schools, and retail HVAC systems, replace the 16x25x1 Beverage Board Pleated Air Filter every 60 to 90 days during routine scheduled maintenance.
High-Humidity & Coastal Applications: In coastal air intake setups, humid processing zones, or high-traffic facilities, inspect monthly and replace this 16x25x1 moisture-resistant cardboard filter every 30 to 45 days. The high-density frame maintains structural rigidity even in 80%+ RH environments.
High-Velocity / Industrial Intakes: For high-volume air handlers, spray booth intakes, or VAV systems, replace when differential pressure reaches 0.50 in. w.g. (125 Pa) to avoid excessive fan motor drag.
Maintenance Best Practice: Always check edge seals when sliding filters into 16″ x 25″ side-access tracks to ensure a tight, bypass-free perimeter seal.
Frequently Asked Questions About 16x25x1 Beverage Board Pleated Air Filter
Q1: What is the actual size of a 16x25x1 Beverage Board Pleated Air Filter?
A: While 16″ x 25″ x 1″ is the nominal size used for ordering, the standard actual size of a 16x25x1 Beverage Board Pleated Air Filter is 15.5″ x 24.5″ x 0.75″ (395 x 622 x 20 mm). This precise sizing ensures a snug, bypass-free fit in standard 16×25 HVAC filter tracks.
Q2: How does a beverage board frame perform in high-humidity or coastal environments?
A: Beverage board is a high-density, moisture-impervious cardboard engineered to resist water vapor and humidity. Unlike standard cardboard frames that soft or collapse, a 16x25x1 moisture-resistant cardboard filter maintains its structural rigidity and frame shape even in environments with 80%+ relative humidity.
Q3: How often should I replace a 16x25x1 MERV 8 Beverage Board Pleated Air Filter?
A: In standard commercial offices and retail spaces, replace the filter every 60 to 90 days. For high-humidity setups, coastal intakes, or industrial workshops, inspect monthly and replace every 30 to 45 days (or when differential pressure reaches 0.50 in. w.g. / 125 Pa).
Q4: Why choose a 16x25x1 beverage board pleated filter over a flat fiberglass filter?
A: The V-pleat geometry provides significantly more media surface area than flat fiberglass. This delivers a much higher dust-holding capacity (DHC) and captures 70%–85% of airborne particles (3.0–10.0 µm) while maintaining ultra-low initial resistance (~0.15 in. w.g.) to protect fan motors and save energy.
Q5: Can this 16x25x1 filter be used as a primary pre-filter in multi-stage HVAC systems?
A: Yes. The 16x25x1 Beverage Board Pleated Air Filter serves as an ideal first line of defense upstream of secondary medium-efficiency or HEPA filters. It traps coarse dust and debris early, extending the lifespan of expensive downstream filters by 2 to 3 times.
