Power The power on my unit will not turn on at all. I have cleaned it and made sure everything is put together correctly, however it will not turn on in any setting. Any suggestions?

Be sure to clean ALL metal parts inside the unit, not just the 3 removable fins.

check connection ware.

When you cleaned everything did you also turn the whole unit upside down and gently shake to remove trapped dirt in the bottom of the unit. As for taking this unit apart to clean throughly there is no need. Just use some q-tips with 91% Isopropal alcohol not Rubbing alcohol to get to the small areas. Pay close attention to the small arrow shaped metal contact near the bottom of the unit. Make sure it is wiped clean and everything is completely dry. Plug unit back into power and the red button should turn green.

Check the switch and make sure that it is getting power. You can also disconnect the connectors to the swiitch plug the unit back in and touch them together if that works then you know the switch is bad

When you cleaned your cleaner, you must be gentle with it. Wipe down with a lightly moist cloth or paper towel. make sure you dont shove any grime between the metal cleaning grid and the plastic holding it all together. that can cause lots of problems. Your air purifier probably wont start because of an auto shut off safety feature. Be sure that everything is in its proper place.... make sure hte front grill is fastened on correctly as well as the back grill. if those are not secured properly the unit will not start. also, check that your collection grid is placed all the way inside the unit and wait for the click noise that indicates that its locked in place. at that point the unit should turn on and you can once again enjoy fresh, pure air!

Just wanted to make sure you inserted the carbon filter on the back before turning it on. It will not turn on without the filter in place. Also, you have to make sure the on/off switch on the back is turned on. Hope that might help.

make sure the filter is seated in the unit correctly there is a right and wrong way and unless the connection is made it won't start

I have two Quadras not sure about the GPS. The only way to clean them properly is to complete the folowing steps. This will eliminate the hissing noises and intermittent shutdowns. Clean the blade unit as normal and leave it out of the unit. Unplug the unit, remove the four phillip screws on the top of the unit where the collector grid slides down. Next remove the four screws holding on to the base of the unit. After this you will see two additional screws also by the base that need to be removed. Look carefully between the grills of the unit and you will see about 12 to fifteen tiny screws that hold the grill together. After these are removed take off the UL label and seprate the grill. You may have to gently pull up on the top where the power switch is located. I have found if you use a lightly dampened scotch brite pad to carefully clean the two wires works best. Clean the wires and pins at the bottom and make sure all is well. Use a microfiber or lint free cloth to gently wipe everthing down and make sure the unit is dry. Put it back together and put the UL sticker back on.

Power Off the unit then Press and HOLD the Off-Timer and Function buttons at the same time WHILE Powering the unit back On. The Replace Filter light will blink for 5 seconds than go out. Now you can release the the buttons.

Just to make sure everything is working fine power off and on the unit.

On a side note if you are a tight wad like me you may want to just smak the filter layers against the ground a few times to clean them and re-use them / make them last longer. When the replace fileter light comes on too often then it is time to replace the filter.

No worries ;o)

When you clean this unit, the plate should be soaked in a 50% amonia to water solution for about 8 minutes. Take a toothbrush and scrub each side of plate and let copletely dry. Take a qtip and dip in rubbing alcohol and swab each of the metal electrodes that touch the plate....This should have that freash air smell back again.!!
