I have a Bionaire Purifer,model # BAP 1175. replaced the filters, but cannot reset digital display

Try to do a hard reset by unplugging the device from the power outlet and wait for sometime to reconnect.

no that isn't normal. it should be coming out of both sides cause the air intake is in the back of the unit where the filters are. try to reset the unit but the pin hole at the top or unplugging the unit for about 10 seconds.... if that doesn't work i would call the manufacturer and to see what other ways or if the unit can be replaced.

click on this link and get the service manual or info u need

there should be a small pin hole somewhere on the top of the unit. Stick a pin in there hold for about 3 seconds and it should reset.

there is only one other thing that i can think of that might work ifyou haven't done that yet. right above the timer button there is a small pin hole. that is your reset button. you need like a safety pin or something really small to go in that hole. hold it for about 3 seconds. take the pin out and the system should reset back to normal. sometimes when you clean the filters that happens. not every time but sometimes. Now if that doesn't work. i would call the manufacturer again so see if they have any other solutions or if they can send you one more. I do apologize for the inconvenience. I will keep looking for you to see if there is anything else that i can suggest but try that first.

Reset filter reminder:
Unplug power code.
Push and hold sleep button.
Plug power code while pushing sleep button.
LCD shows "P" than release the button.
Push sleep button and you can see 99% filter reminder.

It worked - the solution to press sleep and the power button simultaeneously worked! Air cleaner then reset to 99%. Thank you Harbourman!

I have a Bionaire tower air filter model BAP1700 that I bought from Costco. The filter check LED came on recently after 5 months of use. After cleaning the Permatech filters, I tried every remedy on this website including following the instructions that say push power button for 2 secs. Nothing worked. Then I noticed a tiny hole on the control panel in front of clean filter LED; I pushed a paper clip pin into that hole, felt a click, held it down and 2 secs later, LED went out. Success!
