Question about Alpine Air XL-15 Air Purifier

1 Answer

Ozone output stopped

I have an XL which is about 14 yrs old. It has one plate and handles 3,000 sq. ft. It stopped making ozone as it was running. I see no loose connections or wires broken. The front switch is on manual and I checked the seating of the module in the rear. The pencil ion light is on,so the rest of the system works.

I am not familiar with your particular model. I can give you a generic type answer.

In these units there is a high voltage generator module. This module can fail, and therefore no ozone will be produced. It is possible that the power source that drives the module has also failed.

If you get in touch with the manufacture, maybe they can sell you spare parts, or at least inform you about how you can get the unit serviced.

As for my own opinion, when considering the age of the unit I would consider replacing it with a new model. The cost of servicing your unit may approach that of a new one which will have a warranty and higher reliability.

How do I read the graduations on the purifier control & what do the 1 or 2 red plate settings tell me?


The graduations are incremental for your ozone output for the purifier control. Generally, the machine can put out enough ozone to cover 3000 sq ft. (when the control is moved all the way to the right, about 5 o'clock.) Half way should be about 1500 sq ft or 12 o'clock. For general air cleansing, you should set the purifier control to produce enough ozone so you smell it when walking into the room (after home) for about 30 seconds. The ozone smell should disappear after that. If it lingers, you've got it set too high. For more severe odor control you can set it higher but remember that some of us are more sensitive to the odor no matter what the setting. It may need some adjustment based on your individual preferences.

I'm confused about the 'red plates' as you mentioned. The original machine comes w/ 2 ozone plates (made of glass) and doesn't produce ozone when one of the plates is removed. I'm guessing that the lines may tell you when you're engaging both plates to work, i.e. more ozone being produced & blown into the room or less only calling on one plate to produce ozone. If you send me a close up pic of the control panel I may be able to tell you more.

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 have two that quit the ozone part. Just the fan works. I have a XL 15 and 880, that I can still smell just a little ozone. Can I fix these myself?


You might be able to fix them.
There a couple of things that can go wrong with these units, dirty plates, bad contacts, and bad reostat.

Dirty plates:

The ozone is generated by the purification plates. They should be cleaned once a month with a solution of one part amonia and one part tap water. Use a soft bristle brush like an old toothbrush and scrub the metal contacts on the plates with the amonia solution. Be sure to do both sides. Allow them to sit with the solution for 10 minutes, then rinse off with tap water and allow it to dry completely.

Bad Contacts:

There is a couple of metal strips that make contact with the purification plate. Check the contact strips and wires for corrosion. The metal strips can also be cleaned with the amonia solution as well.

Bad Reostat:

The reostat is the part that attaches to the control knob that sets the purification levels. Sometimes it can go bad. The easilest way to check them is to use a meter and verify that as the knob is turned that the resistance changes with the position of the knob.

You probably have a burned out high voltage transformer. That's what produces the ozone. Helpful hint...........the high voltage transformer is also the one used in bug zappers

My Alpine Air XL-15 Air Purifier youst to have a


The Classic XL-15 should have 2 individual indicator lights. The 'red' light is the ionizer indicator, and the 'green' light is the ozone level indicator. Both lights should be illuminated, if the unit is operating properly. The red light should be pulsing, and the green light should be dimly lit, and brightened as the output knob is turned up - indicating a higher ozone production. If the green light is not lit, you likely won't smell the ozone. The first thing you should try, is cleaning the filter and glass ozone plate. Unplug the unit and remove the rear air filter. Clean the filter with clean water and allow to COMPLETELY air dry. Removed the glass plate by depressing the lever behind the glass plate, and gently pulling it out. Clean the glass with a half water, half ammonia (or distilled white vinegar, if ammonia not available) and an old toothbrush to clean between the mesh. Dry plate with a hair dryer and re-place plate into unit. Replace dried air filter, making sure the little tab on the bottom is secured into the interlock. Power the unit on and you should see the indicator lights and smell the fresh ozone!

Living Air XL 15, no ozone


My XL-15 had the same problem a few years ago. I had a broken wire on the fan, and the Ozone problem turned out to be a problem with the power supply. I had to send it in to have it repaired.
