What does a blinking blue light indicate?

"A blinking light indicates when the blades should be wiped clean with a damp cloth." I actually had a "handyman" contract last year to visit an elderly gentleman once a month and clean all 9 of his Ionic Breeze GP air purifiers. Before I did that for him, they would make hissing noises and he really didn't like that. Here's how to clean the operative compnents of these machines: First, unplug the machine and place on a work surface, such as a table or kitchen counter. Second, remove the metal blade insert from the top by gripping the release tab and lifting it up and out. Also remove the front and back grilles by pressing on the plastic tab at the bottom and lifting up on them. Third, use a damp rag or paper towel to wipe the three metal blades clean. Do not immerse this assembly in water, because it has to be completely dry when re-installing it in the machine. Fourth, use a small piece of damp paper towel to VERY GENTLY wipe clean the two thin wires inside the unit. These are located behind the two rubbery flat blades just inside the unit and can be accessed from the front side. You won't damage these rubbery flat blades by pushing your hand gently between them, but be VERY CAREFUL when wiping the wires clean. (This step is important, as the wires must be clean.) Fifth, using another bit of damp paper towel, carefully clean the wire attached to the inside of the front grille. Dry this off with a dry bit of paper towel, then clean any accumulated dirt off the front & back grilles. Check the metal contact near the bottom of the front grille (attached to the wire) to verify that it's clean and will make good electrical contact. Sixth, pick the unit up and turn it upside-down & right-side up about 6 to 8 times. The two wires inside have plastic beads on them that slide up and down the wires. This brushes any bits of leftover dust or lint off of the wires. (Again, these wires must be VERY clean.) Seventh, replace the front and back plastic grilles by placing them in their slots and sliding them down to snap into place. Verify that the assembly with the three metal blades is COMPLETELY dry, using a hair dryer if necessary to dry off damp areas, then slide it back into place from the top of the machine. Now the cleaning process is done, so plug the unit in and turn it on to test operation. If it makes ANY noise, then some component is not completely cleaned off, or still has a presence of moisture, which must be completely dried off before the machine is ready for operation. Hope this helps! ;)

I to have had the problem with the blinking light and could not get it to stop.

I am a very persistent person. I took my unit apart and located the wire that one person indicated is the problem. It look to be the equivalent of brain surgery to work on this wire so i just cleaned the unit very well using a wet cloth and a clean paint brush to dust other areas inside. This was probably good but when I put the front and rear grilles back on and plugged it in the light still blinked.

I decided to find a reset by unplugging the unit and holding down the "boost" button. I tried several scenarios and unfortunately cannot tell you exactly what combination worked because the blinking light problem no longer exists to go through steps to determine which combination worked. What I can tell you is that it was simple. Unplug the unit, hold down the boost and plug it in while continuing to hold it down. After 2-3 seconds release it. Now if this does not work for you try the same with the knobs left knob turned off or on another setting. It will not take long to find the combination if you follow , unplug, hold down button, try different knob position method. I wish you luck.

I fixed the problem by getting a power supply (the part that plugs into the wall socket) that has a higher amp rating. the plug that came with mine was rated for 12 volts and 500 mA and i replaced it with a 12 volt 1000mA (or 1A) and it now works better on low than it did on high before. however it still has the blinking blue light on high. so far it works!
