Still getting dust build up after installing an IQ air system

You will need to run an actualy HEPA filtered air filter as well. The air purifier will oxidize pollutants and will attract and trap some small dust, but most small units also require additional filtering to trap inert neutral charged dust.

Nothing collecting on strips

Larry, since this unit is electrostatic, you may or may not hear little crackles of sparks when it is operational. You should, however, smell a very faint odor of ozone when it is running properly. If you do not hear any sounds from the electrical plates and the air coming out of the unit does not have a little different smell than the air in the rest of the room, then the unit is not functioning properly. In my research of these units, I did see references to replacing the metal fins being required as some claimed they were an consumable element to the purifier and needed periodic replacement to function properly. However, nothing in the owner's manual says they are. It simply says to carefully clean them to avoid damaging the fins or plastic insulation on them.

Other factors to check include:
Making sure the unit has at least 12" of open space behind it.
Making sure there is 36" of open space in front of it.
Give time for dust to accumulate. The manual states that you should check the collection fins after a couple of days to see how much dust has accumulated since cleaning schedules will vary greatly depending on how dusty your home is. Dust collection may take days to start to appear.
Make sure the DRYING CYCLE light is not on when the unit is operating. This protection system is designed to remove electrical power from the fins if humidity is detected (which can easily be the case since you are advised to wash the fins in water to clean them).

If the DRYING CYCLE light is not on, you have plenty of air space around the unit, and after days you still do not see anything on the fins, then chances are the issue is internal and will require repair or replacement of parts. Be advised that this unit is no longer made and has no manufacturer supported service or parts availability. Further diagnosis and repair could quickly get costly and in most cases, you are probably better off replacing the unit.

There is a blue spark and bug zapping sound-looks like its sparking on the ceramic ozone plate. The place looks fine-no cracks.

It's doing exactly what it's supposed to do. The bug zapping sound is from dust particles in the air, that's being pulled thru the unit. However, it should not being doing in continuously (unless your home is really dusty), it may simply need cleaning. Cleaning the unit, about once a month is recommended.

Hope this helped you.

My xl15 runs but does not produce ozone. The little Rulien fan on the little ozone maker does not run. the regular fan works though.

You realize this is a really old machine!! The little fan is for ozone level detection, not production.
To see if the machine still will produce ozone
1) Set the switch to manual rather than auto and always run it on manual.
2) Remove the back of the machine and remove the 4" white plates. Check them for cracks, breaks in the mesh, loose mucilage, discoloration, burned spots, excessive grease or nicotine, or particulates such as dust, dog hair, or lint. Clean the plates using a solution of 1 part plain AMMONIA to 1 part warm water. Soak 5 minutes, brush with a soft brush, rinse well, and blow dry. DO NOT use any kind of cloth to dry the plate. Avoid putting fingers on the mesh.
3) If the plates are damaged in any way, call Vollara (new name for EcoQuest) and order replacements. 1-800-989-2299. Use #16618 as the dealer referral number if you are no longer in touch with the registered distributor who sold you the machine.
4) Insert the plates, making sure the metal contact fingers press on them firmly.
5) If none of the above works, most likely the power to those contact fingers is no longer strong enough to arc through the plates.
6) Call customer service, and they'll explain your options.

I've replaced the filter. why won't the red replace filter light shut off?!

Remove the front cover and locate the FILTER RESET button above the dust sensor level indicator lights. Press and hold this button for 3 seconds until the unit emits a beep and the REPLACE FILTER light goes out.

My Fresh Air by EcoQuest blows out black like dust/substance. So much so that around the unit and on the wall is turning black. Is this working properly?

The unit is designed to drop particulates out of the air. If you have a heavily polluted area there are more allergens/dust in the air and this might create a 'dust-shower'.
The unit charges particles negatively so the particles bond with positively charged particles. Then the particles drop out of the air or stick to a nearby object. This could leave some black stuff on the wall. You can easily wipe this off, most of this is grime/dust.

The air purifier is blowing black soot.

I had the same problem and then found that it was from burning aroma candles! I will never burn them again!

Help! My air ilter quit!

I bought one a year ago and never thought it work well in cleaning the air. I get more dust on my counters than collects in the pure-ion. I recently got a letter from an attorney saying they are settling a class action suit on these purifiers because the are not effective. I called brookstone and they said they will refund my money because of the law suit. Good luck.
