Choosing air comfort equipment starts with one key question: are you trying to cool and heat a room, or replace a filter in an existing air conditioner? The two AIRO Comfort portable units are room-climate machines with heating in their titles, while the two Comfort Aire choices are replacement filters identified by part number. Treat them as separate purchase decisions rather than interchangeable alternatives.
Quick take
For a portable air conditioner and heater, the AIRO Comfort 16000 BTU Portable Air Conditioner Inverter Dual Hose Heater is the more configuration-specific choice, with inverter and dual-hose language plus a stated room coverage of up to 850 square feet. The AIRO COMFORT 16000 BTU Portable Air Conditioner Heater has a listed price that is $52.50 lower and describes cooling as 16,000 BTU ASHRAE and 12,000 BTU SACC.
For a filter replacement, the decision is more exacting. Choose between Comfort Aire Air Conditioner Part # 12100204000202 - Filter and Comfort Aire Air Conditioner Part # 12120300005844 - Air Filter by the part number required. The latter is also described as a 7-1/2 by 13-inch air filter.

Product notes
AIRO Comfort Inverter Dual Hose Portable Air Conditioner Heater
Pick this portable unit when the inverter and dual-hose configuration matters to your room-climate setup. Along with 16,000 BTU cooling, the description calls out heating, dehumidification, a multi-speed fan, a digital interface, a remote, and a DIY window kit. It is the clearest fit in this group for someone seeking one portable machine that covers multiple air-comfort functions, including a stated room size of up to 850 square feet. Its limitation is the listed price: at $448, it is the highest-priced choice here, so it makes most sense when those portable-unit features are the actual goal.
AIRO COMFORT Portable Air Conditioner Heater
This is the portable AC/heater to consider when its $395.50 listed price and stated cooling measurements are the deciding factors. The description gives both 16,000 BTU ASHRAE and 12,000 BTU SACC figures, while the title confirms the heater function and the attributes identify it as a white portable air conditioner. It suits a shopper who wants a room-focused cooling and heating unit without moving into filter-only replacement parts. The limitation is straightforward: it remains a complete portable air conditioner purchase, so it addresses a different need from either Comfort Aire filter.
Comfort Aire Part # 12100204000202 Filter
Choose this $12.61 item when the needed replacement is explicitly identified as Comfort Aire Air Conditioner Part # 12100204000202. The title and description both identify it as a filter, and the description also associates it with the alternate references MDA12100204000202 and CMF12100204000202. That makes the part-number focus more useful than comparing it by general air-conditioner features. Its limitation is equally clear: this is a replacement filter, not a portable air conditioner, heater, dehumidifier, or fan solution for changing the climate in a room.
Comfort Aire Part # 12120300005844 Air Filter
Select this $13.53 Comfort Aire air filter when Part # 12120300005844 is the replacement designation you need. Its description adds a concrete 7-1/2 by 13-inch size, giving this option a clearly stated filter format. It is the appropriate choice for a filter-specific task rather than a room cooling or heating purchase, and its price stays close to the other replacement filter in this comparison. The limitation is its specificity: it is a distinctly numbered air filter with stated dimensions, so it is not the same identified part as the 12100204000202 filter.
Final recommendation by use case
Choose the AIRO Comfort Inverter Dual Hose Portable Air Conditioner Heater for the most explicitly described all-in-one portable setup and its stated larger-room coverage. Choose the AIRO COMFORT Portable Air Conditioner Heater when the paired ASHRAE and SACC cooling figures and lower listed price are more relevant. For replacement parts, make the exact part number the deciding factor: 12100204000202 for the Comfort Aire filter, or 12120300005844 for the 7-1/2 by 13-inch Comfort Aire air filter.
