Used it to clear out my 8sleep. I believe it works

I wasn't really sure what to expect for this. I saw on a reddit forum about purchasing this to mix with water in the 8sleep to clear out any of the bacteria or nastyness that ends up clogging the drain lines and breaking the machine. I used 3x the strength on the bottle and filled/flushed 3 tanks worth. It went from not working at all, to working like it did from when I first purchased it. I wish I would have been using this stuff from the start and would have avoided having to break down the machine entirely and working tirelessly with 8sleep's dreadful customer service.

After refurbishing a humidifier in expectation of having a tracheostomy patient in the house, I spent the extra money on Refresh C because a little extra immune support can't hurt, right? But when it came time for a refill, and it's winter so we're going through it FAST, I figured I'd try the regular bacteriostatic. I'm not having any problems with hard water deposits or murky water, the only thing working overtime seems to be the filter, but as long as i rinse it regularly, it doesnt turn into a rock. This product smells amazing. Not strong. A barely there type fragrance thatvis fresh and clean. I'd only noticed when thenbottle was open before, but i cleaned the whole ynit last night and you use more product the refilling the humidifier after maintenance. Walked out of my room this morning and the house smells awesome. Very light, barely there, but noticably better than when i went to sleep. Will continue to purchase, the scent makes me smile.

I use it for Humidifier device, so the water doesn't get contaminated with bacteria. It works, no white, stinky residues, water is clean and the air is safe.
