A: The Check Filter LED Indicator illuminates to alert you when the Stainless
 Steel Filter Assembly needs to be checked for cleaning. It may be 
 necessary to clean the Filter Assembly more frequently depending on 
 the air quality in your environment.
Q: Can I leave my Ionic Comfort® Plus on continuously?
A: Yes. Your Ionic Comfort® Plus only consumes 15 watts for Model A501 
 and 25 watts for Model A551. It is safe and economical to leave on as 
 long as you like - even 24 hours per day, 365 days per year.
Q: Will my Ionic Comfort® Plus interfere with home or office equipment 
 (e.g. computers)?
A: No. The Ionic Comfort® Plus meets FCC regulations for harmful 
 interference with radio communications so you may place your Ionic 
 Comfort® Plus by your computer, audio players, etc. without causing any 
 unusual interference problems.
Q: Will the Stainless Steel Filter wear out over time?
A: No. The Stainless Steel Filter Assembly is made of high quality 
 corrosion resistant stainless steel. Be careful not to bend the plates. If 
 the plates touch each other, the electrostatic filtration will be impaired.
 Note that some phosphate-free dishwasher detergents can react with
 aluminum and cause staining. It’s recommended to try water-only cleaning     
 first if washing filter in dishwasher.
