Product review (5 stars): Skuttle 86-ud is a durable product and should last many years
Ive had the unit installed for a month now .It works dam good .I'll probably look for a better controller with an outside air sensor .This unit was the perfect unit for my old forced air heater . 12"x 8"  supply ducts . I cut the opening around 3 feet from the vertical plenum . .The baffle that comes with had to be cut a little . My average indoor humidity is making  38 to 45 %  before the install I was around 20 % /This unit is capable of producing over 50 % but that would be too high for my taste .My home is roughly 2000 square foot not counting the basement .I would recommend this unit if you cant afford steam . I think steam is the best choice but rather expensive .
Cheers !!
