Question about Ecoquest Fresh Air Air Purifier

2 Answers

Fan Noise We took the machine apart and did the monthly cleaning, but when we turned the machine back on it made a horrible and constant noise.....I'm assuming it is from the fan as none of the other parts are cracked or need to be replaced.

Re: Fan Noise

Your fan motor probably needs additional maintenance, in the way of lubrication.

After removing the unit from power, access the Fan blade and spin with finger. If there is any resistance to note then the spindle running through 2 bearing surfaces needs lubrication.

See the other question/answer to fan removal - motor lube.

If you have any sort of humidity to contend with and have a FreshAir model F1 or earlier different type, they seem to have some corrosion problems after a period of a couple years.

It is just a function of the machine/job that necessitates such maintenance.

Re: Fan Noise

Make sure you lay the machine down on its back when you lub it. The oil will lub behind the fan. WD 40 works.

How do I fix the noise?

let it dry completely, disassemble as you would for cleaning, and remove filter unit. Inspect to make sure no paper or other debris like a seal has been dislodged. If you can see fan blade, see if it will turn with filter removed. If it moves easily, reassemble carefully and make sure the contacts are oriented correctly and any charcoal filter is on place as well. Try unit.

If noise persists, the unit has to be opened up to inspect bearings of fan/motor and to locate and remove any debris. At that time a drop of light sewing machine oil or pellet gun oil to lubricate the bearings is a good idea.

How do I know when it is time to service my Living Air 880?

This is one of the first models manufactured by Alpine, and is at least 15 years old. It's pretty basic, however, and if it's maintained monthly or bi-monthly, it probably will just keep on going and another little advertising icon says!
The two most important parts are the white plates with the screens attached, and the fan. If the machine is making strange squeeking or grinding noises, the fan needs oiling. Even if no noise is audible, the fan still needs oiling occasionally, like any fan in any appliance.
1) Unplug the machine.
Remove the front grid, gently but firmly pull off the fan blades, and

The fan makes noise when turning

It probably need oiling. The fan motor should be oiled at least every two months. For complete cleaning instructions (including oiling) e-mail to Ask for their free cleaning instructions. They will be glad to help.

Cleaning the top of the oreck air purifier

what i normally do, is i take off the top of the and remove the filter, the metal dust catcher, and the back filter... i was the 2 filters and rub them down. then with the metal dust catcher i take a butter knife. wrap it in a clorox wipe (making sure that no metal is exposed to scratch) then i feed it through the metal dust catcher one at a time to clean it. It took me 5 wipes to clean the whole thing. when the wipe comes out black then i rotate it. As for the top of the machine. there are 2 screws that i removed to get to the fan. when they were out i used a can of air (like you would clean a computer with) and blew out the fan... it took care of all noise and it runs just like the day i got it.
