Reviews of Protec WF2 Extended Life Replacement Humidifier Filter(Pack of 3)

Customer Ratings:

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.

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.

This replacement filter does just the trick. I run my Vics V3100 on high every night and the filter lasts just under two months for me (the box states: "The Cool Mist Wicking Filter should be replaced about every two months, depending on use and local water hardness.") If the humidifier tank runs out of water while running, the filter will dry up completely until you add more water I've found that this practice reduces the life of the filter.

Note: One point of confusion is how Amazon lists this item (as of 1/24/10). The title reads: "2 Filters (Pack of 3)" actually, each box only contains 1 filter. The packaging is confusing as there's a big 2 on the top right of the box. However, if you look at the lower right corner of the box, in much smaller print you see "Contains 1 filter." So, in summary, you are ordering a total of 3 filters (1 Filter/box, Pack of 3 boxes).

I've used a humidifier that requires these for the past three winters, and really am not happy with the entire situation. These last only a month or slightly longer before needing to be replaced, so they simply are way overpriced for what they provide.

It feels like I'm getting suckered by a racket. Just out of principal, I'd much rather buy a humidifier that's higher performing and spend the extra money there rather than having to deal with ordering two packs of these per winter. They're bulky to store and it's just a hassle.
