Air Conditioning Filters

The 16x24x1 Aerostar measures 15 1/2" x 23 1/2" x 3/4" actual, sized for a nominal 16x24x1 return. Common spec on mid-sized residential furnaces and air handlers, and one of the higher-volume filter sizes in the U.S. residential market. Available in MERV 8 for standard households, MERV 11 for pet owners and mild allergy households, and MERV 13 for fine particulate filtration including smoke and virus-carrying aerosols. The pleated synthetic media construction gives this filter substantially more

The Aerostar 18x36x1 pleated air filter delivers clean air by replacing your air system's vent intake filter. Designed to work with most home and office AC and furnace systems with compatible intake vent sizes, filtering out dust, pollen, bacteria, and other airborne particles. Great indoor air quality is as easy as changing your air filter to Aerostar.

The 18x24x2 Aerostar comes in at 17 3/8" x 23 3/8" x 1 3/4" actual. Built for a nominal 18x24x2 return, which is a common spec on older residential furnaces and many light commercial air handlers. The 2-inch depth gives you roughly twice the debris-holding capacity of a 1-inch filter in the same nominal opening, and the lower pressure drop is easier on the blower motor across its service life. MERV 8 covers standard residential dust and pollen filtration. MERV 11 handles pet dander and most comm

The Aerostar 16x25x5 Replacement Air Filter for Bryant Carrier FILCCFNC0016 Air Systems features a multi-model fit design (see Additional Specifications for full model list) and is available in multiple MERV filtration levels to suit your lifestyle and needs.

Stepping up to a 2-inch depth in a 16x16 return gets you noticeably longer service life and less static pressure than the 1-inch equivalent. This 16x16x2 Aerostar measures 15 1/2" x 15 1/2" x 1 3/4" actual. The deeper pleats hold roughly twice the debris before pressure drop becomes a problem, which means a longer interval between changes and easier breathing room for your blower motor. MERV 8 handles standard residential dust and pollen. MERV 11 covers pet households and mild allergy concerns.

A nominal 20x21x1 return takes a filter at 19 7/8" x 20 7/8" x 3/4" actual. Odd-sized returns like this show up where the original equipment installer used a non-standard grille opening, which is common in custom builds and certain regional HVAC markets. This Aerostar is built to the actual spec without adjustment, so it'll seat properly without forcing or wedging the frame. MERV 8 covers standard household filtration for dust, lint, and pollen. MERV 11 steps up for pet households or homes with

At 23 3/4" x 35 3/4" x 3/4" actual, the 24x36x1 Aerostar fits a nominal 24x36x1 return. This is a larger residential or small commercial size, common on furnaces serving big homes and on some commercial rooftop units that use a 1-inch slot rather than deeper media. Three MERV grades cover the typical filtration range. MERV 8 for baseline dust and pollen filtration. MERV 11 for pet households and mild allergy concerns. MERV 13 for fine particulate capture including smoke, bacteria, and virus-size

Picking a 12x30x1 means you've got a long, narrow return - common on older furnaces and certain horizontal air handler installs. The actual size of this Aerostar is 11 1/2" x 29 1/2" x 3/4", so it'll seat properly in a nominal 12x30x1 grille without forcing the frame. Three MERV grades match the filter to the household. MERV 8 for baseline dust and pollen at lowest airflow restriction. MERV 11 for households with pets, smokers, or mild allergies. MERV 13 for fine particulate filtration including

Square 21x21x1 returns are uncommon enough that you've probably struggled to find this size at a hardware store. This Aerostar measures 20 7/8" x 20 7/8" x 3/4" actual, sized for a nominal 21x21x1 slot. Pleated synthetic media construction with an electrostatic charge built into the fibers. MERV 8 handles standard household dust and pollen. MERV 11 captures pet dander, smoke residue, and most common allergens. MERV 13 takes care of fine particulates including bacteria, virus-sized aerosols, and

Coway Aquamega 100’s water purification system reduces the amount of contaminants in using triple filtration technology.

A nominal 22x24x1 return takes a filter at 21 7/8" x 23 7/8" x 3/4" actual, sized to drop into the grille without binding. This is another size that doesn't appear at most retail outlets, which is one of the reasons odd-size buyers end up ordering direct from manufacturers. MERV 8 handles standard residential dust and pollen filtration. MERV 11 captures pet dander, smoke residue, and most common household allergens. MERV 13 covers fine particulates including bacteria, virus-carrying droplets, an

Need a 12x20x1 that actually fits your return? This Aerostar comes in at 11 1/2" x 19 1/2" x 3/4", matching the real opening in most furnace and air handler returns where a nominal 12x20x1 is specified. The half-inch undersize on each dimension is industry standard and keeps the filter from wedging in the grille track. Three MERV options let you match the filter to what your household actually needs. MERV 8 covers basic dust, pollen, and lint at the lowest static pressure. MERV 11 captures pet d

Direct replacement for the Carrier 13x21 1/2x1 OEM filter spec, sized at an actual 12 7/8" x 21 1/2" x 3/4". This is the filter that ships on a range of older Carrier and Bryant residential systems, and the OEM-branded refill is one of the more expensive consumables in the Carrier parts catalog given the odd nominal dimensions. Aerostar's pleated equivalent meets the dimensional spec without modification. MERV 8 covers standard household filtration: dust, lint, pollen. MERV 11 handles pet househ

The Aerostar 20x25x5 Replacement Air Filter for Bryant Carrier FILCCCAR0020 and FILXXCAR0120 Air Systems features a multi-model fit design (see Additional Specifications for full model list) and is available in multiple MERV filtration levels to suit your lifestyle and needs.

Built for HVAC returns calling for a nominal 10x20x1, this Aerostar filter measures an actual 9 1/2" x 19 1/2" x 3/4". The smaller actual size is intentional and standard across the filter industry, giving the filter room to slide into the grille without binding. Pick your MERV based on what you're actually trying to catch. MERV 8 covers everyday dust, lint, and pollen at the lowest airflow resistance. MERV 11 handles pet dander, smoke, and most household allergens. MERV 13 traps fine particulat

The 10x10x1 Aerostar pleated filter ships at an actual size of 9 1/2" x 9 1/2" x 3/4", which is the trade-standard undersize for a nominal 10x10x1 return. That gap matters: a true 10-inch filter won't seat in a 10-inch grille, and an oversized one tears its frame trying. Three MERV grades cover the typical residential range. MERV 8 handles standard dust, lint, and pollen for households without specific air quality concerns. MERV 11 steps up for pet dander, mold spores, and finer dust if you've g

The 20x24x4 Aerostar fits commercial and residential systems with a 4-inch filter slot, measuring 19 3/8" x 23 3/8" x 3 3/4" actual. The 4-inch depth is where pleated filtration earns its cost: substantially more media than a 1-inch can hold, much lower pressure drop across the filter face, and a service life measured in months rather than weeks. MERV 8 covers baseline residential and light commercial filtration. MERV 11 handles pet households and most allergen concerns. MERV 13 captures fine pa

At an actual 16 1/2" x 21 1/2" x 3/4", this Aerostar fits a nominal 16 1/2 x 21 1/2 x 1 return - another odd size that hardware stores don't stock and that's a common reason buyers end up ordering direct. MERV 8 covers standard residential filtration. MERV 11 handles pet households and most common allergens. MERV 13 captures fine particulates including bacteria, virus carriers, and wildfire smoke - the grade for households with asthma or chronic respiratory health concerns. Pleated synthetic med
