Main trade-off
LG 10,000 BTU Dual Inverter Smart Window Air Conditioner
The extra capacity may be unnecessary in a small shaded bedroom.
Head-to-head
LG LW1022IVSM vs Frigidaire FHWW085WE1: LG fits below Frigidaire’s 24-inch window minimum
The short answer
Choose the Frigidaire FHWW085WE1 for a room that needs about 8,000 BTU and has a suitable window. Choose the LG LW1022IVSM for a higher heat load or an opening too narrow for Frigidaire’s 24-inch minimum. More cooling capacity does not automatically make a better small-bedroom purchase.
Before you choose
The reasoning and the trade-offs
A sunny bedroom can cross the smaller unit’s threshold
A very sunny 350 sq ft room with three regular occupants reaches 9,400 BTU in the simple screening example. LG’s 10,000 BTU rating is closer to that requirement.
What this is based on
Using ENERGY STAR’s 8,000 BTU baseline for 300 to 350 sq ft at an 8 ft ceiling: 8,000 × 1.10 + 600 = 9,400 BTU.

About this comparison
LG LW1022IVSM vs Frigidaire FHWW085WE1 compares 10,000 vs 8,000 BTU inverter cooling, narrow-window fit and sunny-bedroom sizing.
Winner by situation
Start with what you need it to do
The room’s heat load calls for more than 8,000 BTU
A room with afternoon sun and a desk used by several people can move beyond the smaller Frigidaire’s cooling class. The 25% capacity difference gives a clear reason to consider LG. It does not prove a 25% faster cool-down, because airflow, humidity and room construction also matter. Start with the room dimensions and regular occupancy, then check the window. The higher-output unit is useful only when both the load and installation support it.

- Frigidaire 8,000 BTU Inverter Window Room Air Conditioner with Wi-Fi
- Depends
A roughly 300 to 350 sq ft room fits the smaller cooling class
For an enclosed bedroom near the smaller capacity guide, Frigidaire can cover the brief without stepping up merely for a larger number. Its included washable filter is the normal maintenance item. The premium allergen filter shown in its marketing is an optional purchase. Do not mistake an AC filter for a separately sized air purifier, and do not use the two brands’ lowest noise claims to promise that one will be quieter beside your bed.

My window is 23 inches wide
LG’s 22-inch minimum includes that width. Frigidaire requires 24 inches. Verify height, sill and support requirements separately.

The bedroom must be quiet at full cooling output
LG’s 44 dB claim is for sleep mode and Frigidaire’s headline is a maker test claim. Neither gives a matched full-output comparison for this room.

What matters in practice
The differences that matter
A sunny bedroom can cross the smaller unit’s threshold
A very sunny 350 sq ft room with three regular occupants reaches 9,400 BTU in the simple screening example. LG’s 10,000 BTU rating is closer to that requirement.
How we reached this conclusion
Using ENERGY STAR’s 8,000 BTU baseline for 300 to 350 sq ft at an 8 ft ceiling: 8,000 × 1.10 + 600 = 9,400 BTU.
A smaller-capacity unit does not always fit a smaller opening
Frigidaire has less cooling output but needs a wider and taller opening. LG is the candidate for a 23-inch-wide opening if the rest of its installation requirements are met.
How we reached this conclusion
23 inches meets LG’s 22-inch minimum but is below Frigidaire’s 24-inch minimum. Opening heights are 13 and 14 inches respectively.
A premium AC filter is an extra, not a purifier substitute
Frigidaire’s optional RAC-10 can add filter expense, while its standard washable filter already serves the appliance. Do not choose between these ACs on an assumed room-air-cleaning rate.
How we reached this conclusion
Frigidaire identifies RAC-10 as sold separately. LG’s cooling and control specifications do not provide a matched clean-air delivery rate for this pair.

Meaningful differences
What changes the fit
| What changes | LG 10,000 BTU Dual Inverter Smart Window Air Conditioner | Frigidaire 8,000 BTU Inverter Window Room Air Conditioner with Wi-Fi | Why it matters |
|---|---|---|---|
| Cooling output | 10,000 BTU | 8,000 BTU | Use a room-load estimate to decide whether the 2,000 BTU step is useful. |

| Window width | 22 to 36 inches | 24 to 36 inches | A 23-inch opening is within LG’s width range but below Frigidaire’s minimum. |
| Minimum opening height | 13 inches | 14 inches | The sash opening matters independently of window width. |
| Controls | ThinQ, remote and local controls | Frigidaire app, remote and local controls | Both cover basic connected cooling, so app ownership can break a close tie. |

Choose Frigidaire 8,000 BTU Inverter Window Room Air Conditioner with Wi-Fi. An 8,000 BTU unit avoids buying extra capacity without a reason
What matters in practice
How to make the call
Choose LG for the heat load you actually have
A room with afternoon sun and a desk used by several people can move beyond the smaller Frigidaire’s cooling class. The 25% capacity difference gives a clear reason to consider LG. It does not prove a 25% faster cool-down, because airflow, humidity and room construction also matter. Start with the room dimensions and regular occupancy, then check the window. The higher-output unit is useful only when both the load and installation support it.
Frigidaire suits a more modest bedroom job
For an enclosed bedroom near the smaller capacity guide, Frigidaire can cover the brief without stepping up merely for a larger number. Its included washable filter is the normal maintenance item. The premium allergen filter shown in its marketing is an optional purchase. Do not mistake an AC filter for a separately sized air purifier, and do not use the two brands’ lowest noise claims to promise that one will be quieter beside your bed.
What this comparison cannot tell you
- Published sound figures come from different modes and test conditions. They do not establish which unit will sound quieter in your room.
- Room-size labels are guidance. Sun, occupants, ceiling height, insulation and the installed vent or window seal change the result.
