Humidifier Tank Cleaner 12Pack Demineralization Cleaning Balls – Prevents Hard Water Build-Up, Eliminates White Dust & Odor

I never received this item. After a week, Walmart just refunded the money with no solution to the issue of me not having what I ordered. The least they could've done was offered a different option or a discount on a different item to equal the amount I would've paid for this one. This is the 6th time Walmart has done this to me, just this month. Do better Walmart.

they help keep the humidifier water clean but not for a whole month I thought one would be sufficient for a month but I used three and my tank isn't that big it's standard size ..they make the water smell clean too

haven't even been able to use these yet because I did not know that I could not use water treatment and these together. supposedly it's toxic so I tried the water treatment stuff first and I'm not impressed so on to the blue balls!

easy to use as you just drop in water tank. Didnt work as well as I expected it would. After about 3 days of running off and on water minerals we very evident in tank.

Great product. Works as described. Fast shipping.

these did nothing. Nothing but sink to the bottom of the tank. Also I viewed no bubble action. Wasted my time and money.

We bought these in January and they did nothing. They didn't dissolve at all between January and April

i don't experience the use of cleanser yet,but humidity is of no use,its nothing of what the description says

Fast delivery. They seem to work. I've been using for a couple of months now. I do wipe out my humidifier at least once a week. I put one in my humidifier each month, and as far as I can tell there's been no build-up at all.

I will be returning within 30 minutes so I could see it was leaving white film on my furniture. also seller's description doesn't say what they're made of what's inside of them so that's a little sketchy!
