Review on 💧 HoMedics Demineralization Cartridge 4-Pack: Prevents Hard Water Build-Up, Filters Mineral Deposits, Purifies Water, Eliminates White Dust & Odor by Vincent Blitz

They will work in any humidifier with an opening wide enough for them to fit, which I appreciate because I didn't have to buy a new humidifier. to use them. And they really help get rid of the white dust in my apartment. I live in Chicago and the water here is VERY hard and the white dust is uncontrollable with humidifiers - it doesn't matter that I pour filtered tap water into another filtered Brita pitcher before pouring it into the humidifier, it forms still white dust. These little cartridges really make a difference. However, they don't last more than 2-4 weeks at any given time and sometimes it seems like one in the humidifier tank isn't enough and I need to add two. for now. As such, their construction seems inconsistent (or not strong enough to withstand fluctuations in water hardness, which is frustrating). And for the price, I wish they lasted a little longer. I use two humidifiers 24/7 to get me through the windy Chicago winters, so I feel like I just have to shell out an obscene amount of money for these little things that I have to keep changing. Unfortunately this is the only article I could find.
