The catch
LG 10,000 BTU Dual Inverter Smart Window Air Conditioner
A small shaded bedroom may not need the extra capacity.
Side by side
LG LW1022IVSM vs Frigidaire FHWW085WE1: LG fits in windows under Frigidaire’s 24-inch minimum
Quick verdict
If your room needs about 8,000 BTU and has a suitable window, the Frigidaire FHWW085WE1 is the one. The LG LW1022IVSM is the one for a higher heat load, or for an opening too narrow for Frigidaire’s 24-inch minimum. Extra cooling capacity does not automatically make a better buy for a small bedroom.
Before you buy
Why, and what it costs you
A sunny bedroom can push past the smaller unit’s threshold
In the simple screening example, a very sunny 350 sq ft room with three regular occupants comes to 9,400 BTU. LG’s 10,000 BTU rating sits nearer that requirement.
Where this comes from
ENERGY STAR’s baseline is 8,000 BTU for 300 to 350 sq ft at an 8 ft ceiling, so 8,000 × 1.10 + 600 = 9,400 BTU.

What this page compares
Inverter cooling at 10,000 vs 8,000 BTU, narrow-window fit and sunny-bedroom sizing are what set LG LW1022IVSM and Frigidaire FHWW085WE1 apart.
Which one fits
Pick the situations that sound like you
More than 8,000 BTU is what the room’s heat load requires
Afternoon sun and a desk shared by several people can push a room past the smaller Frigidaire’s cooling class. The 25% capacity difference is a clear reason to look at LG, though it does not prove a 25% faster cool-down, since airflow, humidity and room construction matter too. Begin with the room dimensions and who is regularly in it, then check the window. The higher-output unit is useful only when the load and the installation both support it.

The smaller cooling class suits a room of roughly 300 to 350 sq ft
In an enclosed bedroom near the smaller capacity guide, Frigidaire can do the job without you stepping up just for a bigger number. Maintenance centers on its included washable filter. The premium allergen filter shown in its marketing is an optional purchase. An AC filter is not a separately sized air purifier, and the two brands’ lowest noise claims cannot promise that one will be quieter beside your bed.

In practice
Differences you will notice
A sunny bedroom can push past the smaller unit’s threshold
In the simple screening example, a very sunny 350 sq ft room with three regular occupants comes to 9,400 BTU. LG’s 10,000 BTU rating sits nearer that requirement.
How we worked this out
ENERGY STAR’s baseline is 8,000 BTU for 300 to 350 sq ft at an 8 ft ceiling, so 8,000 × 1.10 + 600 = 9,400 BTU.
A unit with less capacity does not always fit into a smaller opening
Frigidaire gives less cooling output and needs a wider, taller opening. For a 23-inch-wide opening, LG is the candidate, provided the rest of its installation requirements are met.
How we worked this out
23 inches clears LG’s 22-inch minimum and falls under Frigidaire’s 24-inch minimum. The opening heights are 13 and 14 inches respectively.
A premium AC filter is an add-on and does not replace a purifier
Frigidaire’s optional RAC-10 can add filter expense, and its standard washable filter already does the job for the appliance. Do not pick between these ACs based on an assumed room-air-cleaning rate.
How we worked this out
Frigidaire says RAC-10 is sold separately. LG’s cooling and control specifications give no matched clean-air delivery rate for this pair.

Decision guide
How to decide
Pick the Frigidaire FHWW085WE1 when a room needs about 8,000 BTU and the window suits it. Pick the LG LW1022IVSM when the heat load is higher or the opening is too narrow for Frigidaire’s 24-inch minimum. Bigger cooling capacity is not automatically the better small-bedroom purchase.
Let your real heat load point you to LG
Afternoon sun and a desk shared by several people can push a room past the smaller Frigidaire’s cooling class. The 25% capacity difference is a clear reason to look at LG, though it does not prove a 25% faster cool-down, since airflow, humidity and room construction matter too. Begin with the room dimensions and who is regularly in it, then check the window. The higher-output unit is useful only when the load and the installation both support it.
A more modest bedroom job is Frigidaire's territory
In an enclosed bedroom near the smaller capacity guide, Frigidaire can do the job without you stepping up just for a bigger number. Maintenance centers on its included washable filter. The premium allergen filter shown in its marketing is an optional purchase. An AC filter is not a separately sized air purifier, and the two brands’ lowest noise claims cannot promise that one will be quieter beside your bed.
What this page can’t tell you
- Each published sound figure was taken in a different mode and under different test conditions, so none of them settles which unit will sound quieter in your room.
- Room-size labels are guidance only. Sun, occupants, ceiling height, insulation and the installed vent or window seal all alter the result.
