Choosing an air comfort replacement part is less about picking the lowest listed price and more about avoiding a mismatch. This group includes an air-exhaust duct connector, an air-conditioner filter, a 20-inch-by-25-inch media filter two-pack, and a duct pressure transducer. They address different equipment needs, so the right choice starts with the job and identifying number.
Quick take
For a named portable-air-conditioner exhaust connection, the Comfort Aire Air Conditioner Part # 12120600003049 - Connector, Air Exhaust Duct is the focused selection. For a replacement filter tied to an air-conditioner model family, look to Comfort Aire Air Conditioner Part # 12100204000202 - Filter. The Goodman AMP-11-2025-45 (2-Pack) - 20" x 25" x 4.5" Clean Comfort Air Filter M11 is the clearly specified media-filter option, with a two-filter count and MERV 11 rating. The KMC Controls TPE-1476-23 Duct Pressure Transducer UP To 10'' WC Air Comfort belongs in a different decision: a duct-pressure transducer requirement.

Decision matrix

Product notes
KMC Controls TPE-1476-23 Duct Pressure Transducer UP To 10'' WC Air Comfort
Choose the KMC TPE-1476-23 for a request specifically calling for a duct pressure transducer with an up-to-10'' WC designation. Its model number is clearly stated as TPE-1476-23, which gives a precise reference point for a part-specific requirement. At USD 328.08, it is the highest-listed item in this group, consistent with it being a transducer rather than a connector or replacement filter. The stated condition is New - Open box. Its limitation is specialization: this is duct-pressure hardware, so it does not fill the role of the air-exhaust connector or either filter option in this comparison.
Comfort Aire Air Conditioner Part # 12120600003049 - Connector, Air Exhaust Duct
The Comfort Aire 12120600003049 is the straightforward pick when replacing the round Midea unit adaptor described as a connector for an air exhaust duct. The listing associates it with several identifiers, including CMF12120600003049 and B0FWRWTLQV, and names compatible equipment such as Artic King WPPD-14HR5 and Comfort-Aire PS-121B. That breadth is useful for shoppers working from a known compatible model. Its limitation is equally clear from the title: it is an air-exhaust duct connector, not a replacement filter or a duct pressure transducer. Use the part number as the central match point.
Comfort Aire Air Conditioner Part # 12100204000202 - Filter
Pick the Comfort Aire 12100204000202 when the required replacement is the named air-conditioner filter and the equipment appears among its listed model families. The filter is also identified by MDA12100204000202, CMF12100204000202, and B0FWRZZ2BC. Its compatibility list includes Comfort-Aire REG-123J and REG-81J, alongside models from Artic King, Keystone, and Midea. This makes it a focused replacement-part choice rather than a general media-filter selection. The limitation is its part-specific nature: the decision depends on matching 12100204000202 or a listed compatible model, rather than selecting by the Goodman filter's stated nominal dimensions.
Goodman AMP-11-2025-45 (2-Pack) - 20" x 25" x 4.5" Clean Comfort Air Filter M11
The Goodman AMP-11-2025-45 suits shoppers seeking the listed 20" x 25" x 4.5" pleated media-filter format. It includes two filters, carries a MERV 11 rating, and is described with electrostatic polypropylene media, 12 pleats per foot, and a two-piece frame. A listed six-month filter life provides another practical specification for this option. Its limitation is the fixed format stated in the title: it is not the right category of part for a portable-air-conditioner exhaust connection or a duct pressure transducer task. Choose it when the stated dimensions and AMP-11-2025-45 model match the filter requirement.
Final recommendation by use case
Choose the Comfort Aire connector for the 12120600003049 exhaust-duct connection task. Choose the Comfort Aire filter for the 12100204000202 air-conditioner filter task. Select the Goodman AMP-11-2025-45 when the requirement is the stated MERV 11, two-pack media filter format. Reserve the KMC TPE-1476-23 for a duct-pressure transducer need. In this set, matching the component category and exact identifier matters more than comparing the items as interchangeable air comfort purchases.
