I am also not convinced that a generator is medically necessary for a CPAP machine, because unlike a ventilator, you are not likely to suffer immediate harm if the CPAP shuts off in the middle of the night. And you can easily buy rechargeable batteries for CPAP machines for much less than the cost of a whole house generator.
And lastly, if you do claim the generator cost as a deductible medical expense, you can’t also include it as a home improvement when you sell the home.
