The DH Lifelabs Hypochlorous Acid Space Disinfection and Deodorization Machine is placed in animal hospitals and pet rooms for cats, dogs, and other pets to remove toilet odors, urine, feces, ammonia odors, etc. It has 3-stage adjustable airflow and covers up to 8 tatami mats (space disinfection and deodorization device (Mini Blue)). Q: What happens if I add too much salt? A: When the device detects a high salt concentration, it will alert you with the salt concentration confirmation lamp flashing, the blue light in the tank flashing, and an alert sound. At this time, electrolysis is stopped, and hypochlorous acid water is not produced. Q: What happens if I add too little or no salt? A: When the device detects a low salt concentration, it will alert you with a low salt alert. At this time, the salt concentration confirmation lamp and the blue light in the tank will light up, and an alert sound will be heard. Q: What is the concentration and pH of the hypochlorous acid water? A: The initial effective chlorine concentration of the hypochlorous acid water produced in the tank is 15-40mg/L. The pH value is 8-9. Q: Why can hypochlorous acid water be made with salt and tap water? A: Hypochlorous acid water is produced by electrolyzing saltwater. Q: How do I know when to replace consumables? A: The evaporative filter is a consumable. When it's time to replace the evaporative filter, the filter replacement lamp will light up and indicate the replacement time. It will light up after about 6 months when operated for an average of 12 hours a day. Q: How long will it run when the tap water tank is full? A: This is the continuous operating time from a full tank at 50% humidity. It runs for about 12 hours at airflow "3". The usage time will be longer if the room humidity is high, and shorter if the humidity is low. Q: The filter replacement lamp is lit, but what happens if I don't replace the filter? A: The filter is a consumable, and its dirt, odor generation, and evaporation capacity will decrease with use. To use this product for a long time, please follow the regular maintenance described in the instruction manual and replace the filter when the filter replacement lamp lights up. Q: The humidity meter reading is flashing, what does this mean? A: The humidity meter reading is an approximate humidity, but the product specification is such that the number will flash when it is below 20%. Please use it as a guide to the humidity in your room.
