always make sure the dehu youre buying is AHAM rated, which is the benchmark for water removal systems..the stated removal capacities are tested at 80f and 60% humidity..so if it says 120 pints thats what it will do in an environment under those atmospheric parameters...Ideal and other non AHAM dehus claim high dehumidification numbers like 70 pints a day..they dont tell you they got that number running it in a 99% humidity wet room, under the conditions we run the numbers are significantly less...i use driease and a phoenix max lgr, both are awesome, quests are great too ill be using one probably in the room im building
