Humidifier Water Cartridge (5-Pack) Compatible with LEVOIT, GENIANI, EVERLASTING, Universal Humidifier Cleaner, Demineralization Cleaning Cartridges - Water Replacement Tablets

I've been using distilled water in my humidifiers for several years. But since gallons of those take up a lot of space & I dislike having my distilled water machine take up so much of my kitchen countertop & sink, I decided to try these in my larger GENIANI Ultrasonic Cool Mist Humidifier a few weeks ago.Perhaps it's too soon to notice a difference, but I've noticed NO deposits whatsoever in either part of that humidifier. Having used a Vornado 4-Gallon Evaporative Humidifier with 2 large honeycomb type wick-filters for two decades prior to replacing that with smaller humidifiers, I'm more than familiar with minerals in tap water. Anywhere else in my home I deal with those deposits with distilled white vinegar when necessary. So, I'm happy to be able to dispense with that in this situation.Note that I also use a few DROPS of Essick Bacteriostatic Treatment daily when I fill the tank—using more results in foaming. That keeps Serratia marcescens bacteria at bay which is essential. (S. marcescens is what's responsible for the pinkish red you'll find in damp areas like your sinks, showers, toilets, humidifiers, etc. if you don't kill it with bleach or prevent it. Simply drying those areas every time is the best preventive but that takes vigilance for which busy families usually don't have the time. So, that nasty bacteria can grow to create slime where you don't want it!)We still have many weeks of winter weather before I can clean & put away my Geniani humidifiers, both of which are at least one-half gallon which is the only stipulation for using these demineralization cartridges—IF they'll fit in the tank opening, that is. So far, I'm very pleased with this product, though. And if it continues to perform like it has, I'll need distilled water for only one humidifier so we can breathe more easily once the heating season arrives.

These work well to stop the white dust. I use two humidifiers in my house all winter and I don't have any white residue on my furniture or in the air.

It's hard to tell if or how well these actually work. We try to use distilled water most of the time anyway and we did experience white dust when using tap water. I would assume these help, but can't say it eliminates all white dust when using tap water.

Easy to use. Great value for the money. Very functional. Nice buy.

Just through them in the humidifier.

On my first cube yet , been using for a month or more

I have used these for 2 years. I have very hard water and these keep my humidifiers clean so much longer. I highly recommend!

PURE FRAUD, these demineralization cartridges do absolutely nothing. They DO NOT remove any minerals.I tested them in 2 liters (.5 gallon) of city tap water, which measured 156 ppm TDS (total dissolved solids) at room temperature, which equals 156 milligrams/liter.I measured the TDS after 24 hours submerged and it actually went up to 166 ppm. Yes, it actually added minerals to the water, 10 mg per liter or 20 mg in the 2 liter sample.The PH measured 7.4 for the entire 24 hours.I weighed the cartridge before at 21.077 grams and after at 21.060 grams: 17 mg lighter.I repeated the test with the second cartridge: same result.I then boiled away all the water and measured what was left: 305 mg of dry powder. See photo.TDS readings are only for electrically conductive minerals.Despicable FRAUD.
