Use it everyday!
The replacement wick, due to its construction, doesn't stand up to multiple cleanings. The glue doesn't hold so there should be more thought into this units construction.
I'm glad I was able to get this product and sent right to my house in a short time but when I went to the store to buy it I had to order it. So frustrating to very rarely find it in the store anymore. My husband had this same problem when he went to buy band saw blades for his craftsmen band saw he bought at sears. Couldn't find them in any store. You sell the saw but NOT the blades for it. He ended-up going to a wood working store to buy some. Shelves in stores are starting to look like a ghost town!
Gggg
My filters were delivered to the wrong address I contacted Sears but they didn't correct the issue.
If you have the machine the refills are a must. I strongly suggest the machine and refills for the hot dry weather (and dust) in the Montana area.
we have very hard water and need to soak the wick in a 10% vinegar/water solution to remove the lime weekly. After 2 to 3 weeks the wick just disintegrates. I am ok with replacing monthly but every two weeks is expensive. Wish it would hold up better.
