I seem to remember the original instructions were to clean the filter regularly. I don''t have a problem with mold or slime buildup, but see they have a product for that.

I have very hard water and so quickly get a buildup of minerals left over as the water evaporates. To remove that, I simply pour some vinegar onto the filter from the top, while it''s still in the machine. As the crust starts to soften (the vinegar dissolves the crust) I pour the liquid in the bottom of the machine into the sink, lay the filter down (it will now flatten without breaking) pour some more vinegar on it (probably 2 cups, total) and let it soak until it stops bubbling. Rinse good with water and it''s ready to go again. I''ve used the same filter for several years. It is now finally disintegrating so I''m buying a new one.

This machine is for the bedroom. I also have a much larger one, different make, same type filter, large-room size, and use the same procedure for it.

I purchase these every year for my Vicks humidifier. I have spent way beyond what the machine itself cost me on filters. Each filter lasts about a month to 6 weeks before getting moldy and stops wicking the water. I only use the humidifier for about 4 months in the Winter, which a 3 pack of filters is good for. I would use it all year if I did not have to keep replacing the filters. If someone knows a better choice of longer lasting filters, please post.

12/9/08-Too bad this is the only place I have easily found these. I cannot believe they have gone up $10 in cost since I purchased them a year ago (11/30/07)!

They fit and work as expected. Just like any other humidifier filter, they need replacing after dirt and minerals build up. These filters work just like to filter that came with the original unit.

These things don''t work remotely as well as teh filter which came with my Viks unit. I would have to replace the water with the orginal filter in the morning, these filters only help lift half the water of the old ones.

I''d like to know how long a non-extended-life pad will last. These are made with one perforated cylinder of foil (with opposing sides very poorly connected if they are connected at all), surrounded on each side by a cylinder of perforated *paper*. I think it''s just the paper that''s holding the cylinder together. It will last a month if you are lucky. Don''t plan on soaking it in vinegar, as it will just fall apart. I think they call this "planned obsolescence". This is obviously where they make their money, similar to ink-jet printers and their costly ink cartridges.
