Question about Sunpentown AC-3000i Air Purifier

Open Question

Bad smell coming from air purifier.

I have 5 Sunpentown AC-3000i air purifiers that are only a month old and within a few days of each other they started producing a bad odor. The filters look fine. Does it have anything to do with the carbon side of the filter?

    It smells extremely similar to marijuana??? No one in my household smokes it... The first week it wasn't like that but we have only had it for two maybe three months.

    I have the same problem with a 2 week old Honeywell 50250 air purifier.After it rained yesterday, the air coming out smells like a wet dog. So is humidity the problem?It is normally a very dry climate here. There is a permanent large filter, wrapped with a black pre filter. Anybody have any suggestions?

    What kind of "bad odor" are we describing?
    Burning electrical insulation (smells like burning automotive brakes)?
    Something else?
    Carbon tends to absorb odors, shouldn't be giving them off?

    Thanks in-advance.

I cleaned purifier plate and filters and purifier still won't workon my fresh air machine

The air purifier filters which need to be washed lose their efficiency very fast and need replacement every few months . I think its time you switched to a better air purifier like this with superior filters which last longer and can be cleaned using a vacuum cleaner Premium Air Purifiers with e2f technology

Air purifier filter smells bad

That's interesting... I doubt it is the filter if the new filter did the same. It might help if you take a fan and blow it through the area behind the filter, or maybe even spraying some Lysol in it, because my best guess is that something inside the purifier is what is causing the smell. Hope this helps!

Smelling of tobacco on cd so bad, how make oddor disapear ?

My solution has nothing to do with air purifiers other than you use them to keep the air clean. In the old days we put household vinegar in a bowl, hid the bowl under the bed or a chair. The vinegar "swallows" the tobacco smell.

Ecoquest fresh air not omitting ozone

Did you clean the plate contacts with alcohol? How old is the plate? Is the glue that holds the grid in place turning brown? If it is, it may need to be replaced. Call (336) 499-2505 and ask for free email supplemental cleaning instructions before you do anything else. The instructions may help you solve the problem.

The machine seems to be working, but I am not getting the same clean smell I use to. I have a bedroom closed up with an old mattress that smells of cigerette smoke, usually this sort of thing is no problem...

Check that the purification plate contacts and associated wiring are clean and make good contact with the plates. Also check the plates themselves for dirt build up on the metal grid. If the plates are a few years old, they should be replaced. Your dealer should be able to help you get new plates. Leave a comment if you need additional help.

I no longer smell the ozone smell that i used too.

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.
