Running these analyses costs money. Buy through my links to help keep lights on! I may get a small commission.
I strongly recommend you avoid evaporative humidifiers and get an aprilaire steam one injecting into the supply ductwork, they are $1100-1500ish installed by a decent HVAC tech and provide far better control than evaporative ones (i.e. pads/drums/ect), and by nature will not grow shit due to old folk not doing the maintenance required on evaporative systems and are more disaster proof (i.e. un-noticed leaks) than evaporative ones as well.
Yup, although I was off on the price and it increased more than $300 over the last couple of years. Still easier to install unless you have a huge house and want to run it on 240VAC and not 120. Personally - I feel 120VAC is a more even change in humidity than the higher voltage and generally install it sucking that.
Aprilaire 800 would recommend
Aprilaire 800 is awesome.
The 800 uses a lot of electricity . I was surprised in the jump in the electric bill.
Aprilair 800 is the best on the market
It really depends on your house and how well sealed it is. We installed a aprilaire 720m and so far has kept our house at 40-45% consistently. But we have a new build, well sealed home. If you have an older leaky house, it may not perform as well. There’s the 800 steam version, but that will use a considerable amount of electricity.
