AI-generated imageA synthetic pleated air filter uses a pleated sheet of synthetic filter media set in a rigid paperboard frame. Pleating packs far more media into the same face area than a flat panel filter, so air passes through at lower resistance while the filter holds more dust before it needs replacing. Air Handler is Grainger's private-label HVAC filter line, and its synthetic pleated range covers MERV 7 through MERV 11 across 1", 2", and 4" nominal depths.
Facilities managers, HVAC contractors, and building maintenance teams rely on these filters for air handling units, rooftop units, and furnace/AC filter racks in offices, schools, and commercial buildings. The MERV rating is the main selection lever: Air Handler's MERV 7 and MERV 8 filters are classified for particles such as cat and dog dander, dust mites, mold spores, and cement dust, with MERV 8 providing between 50% and 70% efficiency on 3-10 micron particles. MERV 10 and MERV 11 filters move up to finer contaminants such as auto emission particulates, humidifier dust, and lead dust, with MERV 11 providing between 80% and 85% efficiency on 3-10 micron particles. A higher rating is not automatically better, because denser media adds airflow resistance that the HVAC system has to be able to handle.
Common configuration: synthetic media in a white beverage board (paperboard) frame, UL 900 Classified, in MERV 7, 8, 10, and 11 ratings. Nominal depth runs 1" (3/4" actual), 2" (1-3/4" actual), or 4" (3-5/8" actual), and listings carry a maximum temperature of either 150°F or 180°F depending on the model. Filters are classed as standard capacity or high capacity, with a maximum velocity of 500 fpm, and media area ranges from about 2.2 sq ft on compact 1" sizes to 28.8 sq ft on a 24x24x4 filter. As a sample of rated airflow, the 16x20x2 MERV 7 filter is listed at 667 cfm at 300 FPM and 1,111 cfm at 500 FPM, while the 24x24x4 MERV 11 filter is listed at 1,200 cfm at 300 FPM. Packs are typically 12 filters for 1" and 2" depths and 6 filters for 4" depths.

Typical furnace, AC, and air handler slots built for a 1" filter, where basic dust and dander control is the goal. MERV 7 standard-capacity filters dominate here.
Commercial air handlers and rooftop units with 2" filter racks that need more media area and longer service life. High-capacity MERV 8 to MERV 10 filters dominate here.
Air handlers with 4" deep filter housings where maximum media area and finer particle capture matter. MERV 11 filters dominate here.
Air Handler's synthetic pleated line spans three nominal depths and four MERV ratings, with standard-capacity and high-capacity options in the most common sizes. Here's how to navigate the range without a 40-tab browser session.

Whether you're a facilities manager standardizing filters across a building, or an HVAC contractor stocking a service van — use this framework before you procure.
Order by the nominal size on the filter frame (for example 16x20x2). Actual dimensions are smaller than nominal, with actual depth running 3/4" for 1" filters, 1-3/4" for 2" filters, and 3-5/8" for 4" filters.
MERV 7 and 8 cover general dust, dander, and mold spores, while MERV 10 and 11 capture finer particulates. Denser media adds airflow resistance, so confirm with your equipment manufacturer before moving up to a higher MERV.
Compare the filter's listed cfm and its 500 fpm maximum velocity against your system's airflow so the filter isn't being pushed past its rating. For example, a 16x20x2 MERV 7 filter is listed at 667 cfm at 300 FPM.
Listings show either a 150°F or 180°F maximum temperature depending on the model, so confirm the rating if the filter sits near a heat source or in a high-temperature air stream.
Most 1" and 2" filters ship in 12-packs and 4" filters in 6-packs. Replacement frequency depends on dust load and runtime, so set a schedule based on how quickly your filters load up and stock accordingly.
Filters are sold by nominal size, and the actual measurements are smaller. Search by function on ChatMRO — the AI surfaces exact matches AND available substitutes at the correct nominal size for your rack.
Higher-MERV media is denser and restricts airflow more, which can strain a system not designed for it. Match the rating to what your equipment can handle rather than defaulting to the highest available.
Maximum temperature varies by model in this line. If the filter will see elevated air temperatures, check the specific listing rather than assuming every Air Handler filter carries the same rating.
Describing your application to ChatMRO takes 30 seconds. The AI reads the full Air Handler pleated filter catalogue so you don't have to.
MERV (minimum efficiency reporting value) measures how effectively a filter removes particles from the air stream by size. Air Handler's synthetic pleated line spans MERV 7 to MERV 11, with MERV 8 providing between 50% and 70% efficiency on 3-10 micron particles and MERV 11 providing between 80% and 85%. Search by MERV rating on ChatMRO to compare pricing and availability instantly.
Nominal size is the rounded size used for ordering (for example 20x28x1), while actual size is the true measurement of the filter, which is smaller. Actual depth is 3/4 inch for 1-inch filters, 1-3/4 inches for 2-inch filters, and 3-5/8 inches for 4-inch filters. ChatMRO can match your nominal size from a single description search.
Listings classify these filters as standard capacity or high capacity. High-capacity models generally offer more pleated media area, which typically means more dust-holding capacity and longer service life, so compare the media area (in sq ft) on the spec sheet. ChatMRO provides access to manufacturer media area and airflow specifications directly from search results.
Yes, the Air Handler synthetic pleated filters in these listings carry UL 900 Classified agency compliance, with synthetic media in a beverage board frame and a maximum temperature of 150°F or 180°F depending on the model.
