Re: XL15

The ozone plates need to be cleaned monthly to work effectively. You can get an owner's manual for free from the manufacturer's website, it's at:

The manual has a description of the type and frequency of cleaning of various parts of your air purifier. Hope this helps!

Re: XL15

If the smell is "stale" (like stale tobacco smoke) it probably needs a good cleaning. I recommend using cleaning ammonia and an old sock for most of the hard surfaces, and an old toothbrush dipped in the ammonia solution for the discharge plates. Use a clean damp sock to rinse/wipe the hard surfaces, and rinse the plate(s) afterward with clean water and allow to dry thoroughly. They have to be absolutely bone-dry before use.

If the smell is "bleachy" or makes your eyes water or throat sore, you likely have the ozone/activated oxygen (O3) control set too-high. You want it _just_ perceptible when you first enter the room, no more. Some people are more sensitive to O3 than others, and you should act accordingly. O3 in clean outdoor air is normally between 10 & 40 ppb (parts-per-billion)- not very much.

If you can vary the smell by adjusting the O3 control knob, do so, and keep adjusting it downward until it is barely noticeable. Turning up the fan helps as well.

Re: XL15

Mine does too. Did a little research - I guess all air filters let out a little bit of ozone. Some describe the smell of ozone to be something like bleach yet others say it smells like geraniums or even "sparks" (like the sparks that come off of the bumper car ride at the fair...hmm...interesting). Not sure which to believe, but I know mine smells.
I found a manual talking about reducing this smell. Said the first couple of weeks are the worst of it, but if it still bothers you, you could install an "activiated carbon filter" down stream from the air filter, or go through complicated instructions (for whatever model they were talking about) to go into the electronics of the machine and switch stuff around.
Both solutions sound complicated to me.
I'm just happy knowing the smell is normal and that it is actually working. Think I'll live with the smell.

I have a terrible smell coming out of my Mitsubishi air-con.

after making sure it will drain properly the best way to permanently remove smells is to use a "ozone machine" or a ionizer this attacks the odor causing molecules and breaks them down. 30-60 minutes from a powerful unit will do the trick , most carpet cleaning companies that also do water repairs have these machines and their rates vary. alpine air also makes a home unit and these are good to use in the home 24/7 as well

We purchased this at a thrift store. Can you tell me what the ionizer setting is for

The ionizer cleans the air. If it's working properly, it will smell like the air right after a lightning storm. You should use as little as possible, based on the size of the area, you're using the unit in. Do not allow it to blow directly on you or anyone else. The higher you can place the unit, the better it will work. Match the fan speed to ionizer setting.

Hope this helped you.

I have the living air xl15 its not working properly, I cant smell ozone no buzzing sound no uv light no green led coming on. I guess the only thing working is the fan. I don't have a manual and it blows my...

I have an extra user manual for the alpine. You have to clean the plates at least once a month to get maximum performance. Get back to me at for the manual. Also the ion emitter sometimes needs to be replaced. I use one of mine in my FIR sauna. It seems to be OK at those high temps. 50*-60* far.

Open the back and change the Ozone plate. then slide out the ION plate and clean it with denatured alcohol. If no light inside, you may have to replace the bulb and / or starter. Hope that helps.

Have a Living Air XL15 > everything works motor, fan, BUT .....

look through the front grill while its "on" you should see a glow from a neon lamp inside. If its not on chances are the circuit card is dead (should have about 350VDC plate voltage).
I have a used but good board if anyone needs one.

XL-15 Classic Living Air emmitting Foul Odor!!

Ionizers do cause a bad odor to happen. I work in the copier business and do work around machines that can cause an ozone to happen when there are ran. Copiers like ionizers can cause an ozone to happen because the air particles are being electrically charged. The smell isn't good to be breathing in as well.

Here is an EPA report about ionizers

The Consumer Products Safety Commission is going to be making a decision about the health effects on ionizers by the end of the year. Their decision can effect selling ionizers all together.

This industry should have been regulated years ago and after what happened to Sharper Image this year due to their arrogance it isn't doing the industry any favors. They went out of business because of Consumer Reports findings and tried to sue them for it.

If you really want the air in your house cleaned, the best way to do it is using a hepa filter.

If that's one of those fanless air purifiers with parallel plates, it is not all right. The plates need to come up to charge and not discharge much at all unless there is a big contaminant particle (e.g. flying insects.) You may or may not be able to make the plates parallel again; there should be no sharp bits. If it's an ionizer, even then the flashing should be rare; otherwise you will get more ozone than you need. That can be fun, but it is not making plain old clean air....

When ionizer is on even

Hi willy,

The ionizer itself shouldn't smell. I wonder if you're smelling O3 (aka ozone or activated oxygen), or if there's a short-circuit of some kind that is causing electrical components to overheat/burn. Burning electronics and singed hair smell more alike than ozone (which isn't the same as ionization, incidentally.

Write back with more details if you can, preferably with any details about your observations.

If I can be of further assistance, let me know. If this solves the issue, please rate it accordingly.

Thanks in-advance for using,
