When shopping for air comfort, the main decision is not simply which item looks closest to the part you need. The bigger question is whether you are replacing a specific air conditioner component, comparing a higher-priced furnace-related part, or looking at an item that does not really belong in the same purchase decision. The four choices here span a very wide listed price range, from a small Comfort Aire filter to a much higher-priced 115-volt draft inducer, plus a Nike running shoe that appears in the mix but serves a completely different purpose.
Quick take
- Best for a low-cost air conditioner part: Comfort Aire Air Conditioner Part # 12100204000202 - Filter. It is the clearest fit when the goal is a replacement filter tied to specific part numbers and model references.
- Best for a display-related Comfort Aire repair: Comfort Aire Air Conditioner Part # 17220300A17150 - Display Box Subassy Box. It is the choice when the needed item is a display box subassy rather than a filter.
- Best for a 115-volt draft inducer need: Armstrong Johnson Air ease Efficiency Ultra 90 Draft Inducer 115 Volts FB. It sits apart from the Comfort Aire air conditioner parts and carries the highest listed price in this group.
- Not an air comfort equipment pick: Nike Air Max 90 PRM Iron Grey University Red Running Shoes HV4517-001 Men Sizes. It may appeal as men's running shoes, but it is not an air conditioner or furnace component.
Listed price comparison
The spread is large: the lowest listed item is the Comfort Aire filter, while the highest listed item is the Armstrong Johnson Air ease Efficiency Ultra 90 Draft Inducer 115 Volts FB. The lowest price is about 95% below the highest, so the right choice depends heavily on whether you need a small replacement part, a display box subassy, a draft inducer, or footwear.
| Product | Listed price | Price bar |
|---|---|---|
| Armstrong Johnson Air ease Efficiency Ultra 90 Draft Inducer 115 Volts FB | USD 259.95 | |
| Comfort Aire Air Conditioner Part # 17220300A17150 - Display Box Subassy Box | USD 42.17 | |

Decision matrix
If you are replacing a named Comfort Aire air conditioner part: Start with the two Comfort Aire entries. The filter and display box subassy are not interchangeable, so the title phrase and part number are the key decision points.
If the part number matters more than the general category: The Comfort Aire filter lists part number language including 12100204000202, while the display box subassy centers on 17220300A17150 and related numbers. That makes the product name more useful than broad wording like "air comfort."
If you need a 115-volt draft inducer: The Armstrong Johnson Air ease Efficiency Ultra 90 Draft Inducer 115 Volts FB is the only item here with "Draft Inducer" and "115 Volts" in the title. It is not competing directly with the Comfort Aire filter or display box subassy.
If you are shopping for shoes: The Nike Air Max 90 PRM Iron Grey University Red Running Shoes HV4517-001 Men Sizes stands on its own. Its relevant cues are men's sizing, lace-up closure, gray color, comfort and cushioned features, and foam insole material.
If you want the narrowest air comfort choice: The filter is the simplest air conditioner part in this set by title. The display box subassy is more specific to the control/display side, and the draft inducer is a different type of component altogether.
Concise product notes
Armstrong Johnson Air ease Efficiency Ultra 90 Draft Inducer 115 Volts FB
This is the pick to focus on when the needed phrase is "Draft Inducer 115 Volts FB." Its title is much more specific than the general air comfort category, and the attributes mention a pneumatic power source, plastic material, one-item package quantity, and no batteries required. The main limitation is that it is not presented as a Comfort Aire air conditioner part, filter, or display box subassy, so it does not solve the same replacement need as the two Comfort Aire items. It also occupies the top end of the price spread, which makes it a more targeted purchase rather than a casual add-on.
Comfort Aire Air Conditioner Part # 17220300A17150 - Display Box Subassy Box
This Comfort Aire option is the most relevant choice when the job calls for a Display Box Subassy Box tied to part # 17220300A17150. The description connects it with several Comfort Aire models, including REG-123L, REG-123M, REG-183J-20A, REG-81M, REG-81L, REG-183L, REG-123J, REG-183J, and REG-183M. That model language gives it a more defined role than a generic replacement piece. Its limitation is just as important: it is a display box subassy, not a filter and not a draft inducer, so shoppers looking for airflow filtration or a 115-volt draft inducer should not treat it as a substitute.
Nike Air Max 90 PRM Iron Grey University Red Running Shoes HV4517-001 Men Sizes
The Nike Air Max 90 PRM Iron Grey University Red Running Shoes HV4517-001 Men Sizes belongs in a different decision lane. It is a men's lace-up running shoe in gray, with comfort and cushioned features and a foam insole material. The title's Iron Grey and University Red color language is useful for shoppers choosing a sneaker style rather than a repair part. The limitation is clear: despite the "Air" name, this is footwear, not air comfort equipment. It will not replace a filter, display box subassy, or draft inducer, so it should only stay on the shortlist for shoppers actually comparing shoes.
Comfort Aire Air Conditioner Part # 12100204000202 - Filter
The Comfort Aire Air Conditioner Part # 12100204000202 - Filter is the cleanest low-end air conditioner part choice in the group. The title names the part as a filter, and the part-number language includes 12100204000202 along with related MDA and CMF references. The description names many model families, including Comfort Aire, Arctic King, Keystone, and Midea model references, which makes it relevant when that exact filter number is the target. Its limitation is that it is only a filter; it does not address a display box subassy replacement, and it is not the 115-volt draft inducer option.
Final recommendation
For most air comfort shoppers, choose by component name first, then use price as a secondary filter. If the needed item is a filter, the Comfort Aire Air Conditioner Part # 12100204000202 - Filter is the most straightforward match and is also the lowest listed item in the group. If the needed item is a display-related Comfort Aire component, choose the Comfort Aire Air Conditioner Part # 17220300A17150 - Display Box Subassy Box, especially when the model references in its description line up with the repair need.
The Armstrong Johnson Air ease Efficiency Ultra 90 Draft Inducer 115 Volts FB is the focused recommendation only when "Draft Inducer," "115 Volts," and "FB" are the relevant title cues. Its position at the top of the price spread reinforces that it should be treated as a specific component choice, not a general alternative to the Comfort Aire parts.
The Nike Air Max 90 PRM Iron Grey University Red Running Shoes HV4517-001 Men Sizes should be separated from the air comfort decision. It may be a valid shoe comparison item for someone seeking men's lace-up running shoes with cushioned features, but it is not part of an air conditioner or furnace repair shortlist.
