The Original Air Probe Sanitizer™ may be tax deductible.
"Capital expenditures for home improvements and additions that are added primarily for medical care qualify as a medical expense only to the extent that the cost of the improvement exceeds any increase in the value of the affected property (Reg. 1.213-1(e)(1). The entire cost of any improvement that does not increase the value of the property is deductible... The entire cost of special equipment used to mitigate the effects of a physical impairment is also deductible."
