The device electrolyzes a teaspoon of salt and tap water into electrolyzed hypochlorous water, spraying it as mist about twice a month for roughly 25 minutes to suppress mold. Planned general price is 29,810 yen, with backer-only early-bird pricing.","whyItMatters":"The pitch rests on the maker's own August survey of 1,000 married parents, which found cleaning harder does not solve mold and that 58.3 percent of anti-mold product buyers quit using them, so the product is sold as a low-effort routine rather than a stronger chemical.","webCardHtml":"\u003cp\u003eThe device is the second in the JOKER line, after the 2019 bath washer, and moves from a floating unit to a stationary one placed in the bathroom. It weighs about 1.4 kg and stands about 290 mm tall, made at the company\u0026#39;s own factory in Izumi, Osaka. A second mode dispenses the generated water through a hose into a commercial spray bottle of around 300 mL, for tables, door handles, toilets, and pet odors. Hatano Seisakusho notes AiR JOKER suppresses mold growth and does not remove mold that has already appeared.\u003c/p\u003e","blueskyPost":"The 29,810 yen AiR JOKER price is not for a filter or a dehumidifier. It covers a unit that makes its own cleaning agent from a teaspoon of salt. That puts the cost comparison against tap water, not against other bathroom gadgets.","twitterPost":"AiR JOKER makes its own cleaning agent from salt and tap water. The 29,810 yen pays for the electrolysis hardware, not the spray.","threadsPost":"AiR JOKER's real cost is the electrolysis unit, not the spray. Users supply a teaspoon of salt and tap water, so the 29,810 yen covers hardware that produces its own hypochlorous water rather than a refill subscription. The maintenance question is the electrode, not the next bottle.","newsletterBlurb":"Hatano Seisakusho will open a CAMPFIRE project for AiR JOKER on September 16.
