I've been looking for a whole house humidifier for a while, and the price on this one just dropped from around $140.

http://www.amazon.com/Aprilaire-5...B0039PR5RE

Model: 500A
Rated for: 3000 sqft (depends on how well your house is sealed)

The digital control should allow you to prevent the huge amounts of condensation that you get from some of the uncontrolled units.

And even more savings will come from turning your thermostat down.

1) You will need to cut a whole in your sheet metal to push air through this filter covered in water into your house.
2) You will need to tap into a hot water line from your hot water heater to provide this water.
3) You will need to run a temperature sensor outside (so it doesn't run above 55F).
4) You will need to provide 120V power (regular 3 prong - but yours may not be close).

sounds worth it to me...
I have had an aprilaire humidifier installed since 1989. I replaced it with this exact one last year. Install was pretty easy since I was replacing the existing unit, moving the control unit to the return air duct (recommended so it can monitor house air humidity with a sensor on the back), and adding the outside thermometer. I highly recommend this unit and was happy with it for the $200 I spent. That said....

My ducts and furnace have not rusted. My furnace is a Rheem 80 installed in 1989. A water softener does not put salt into the house water unless you use the water while it is recharging. That's simply not how it works. People with water softeners are not drinking salt water. Let me explain the process.....

Your water softener has resin in which attracts the ions in your water, pulling the ions out. Your water is delivered to your tap ion free. When the water softener recharges (typically in the wee hours of the night when no one uses the water - although you can choose the time), salt water (brine) is pumped into the resin to free up the ions. The salt water (brine) is then dumped. In my case, it goes to the sump and subsequently out to the yard. It doesn't go to the septic because the salt would hurt the septic environment. With the resin recharged, it's ready for service again.

Phew, long post, I hope that clears things up. Good humidifier. Good deal. Good job, OP.

How hard is it too install?

I paid $175 for the 400 model January 2015 and it is COMPLETELY worth it. The difference in the air in my house is amazing. I had an engineer from work help me install it without much issue. Bought maybe $50 worth of random bits and bobs from Lowe's to get it in.

What is the difference between the 500 and 600? Is 600 just for a larger home above 3000 sq ft?

All said, takes 1.5 to 2 hours. Time absolutely well spent.

#3, installing the outside temperature sensor should be optional. It's only required if you want to use the humidifier in Automatic Mode. You can use the humidifier in Manual Mode by manually adjusting the humidity level based on anticipated outside temperature to avoid condensation on your windows.

does this go on with your AC unit or heating unit?

I have central AC, but baseboard heating. the house gets most dry in the winter when the house is being heated, but im not sure how this unit would work in delivering moisture since baseboard isnt able to put anything into the air.

At least with the way I've installed these, you have to install it on your furnace. The unit turns on when your furnace turns on. With baseboard heating, this likely won't work unless you can get your central AC to turn on the blower-only and push air through this humidifier on some kind of regular intervals. You might be better off with an individual room ultrasonic type humidifier.

I've heard that some of the more advanced thermostats (like the Nest) can turn on your A/C blower fan based on humidity levels. If that is the case, you could definitely use this humidifier.

TIP: make sure you don't tap the water supply *after* a water softener. the salty water will corrode the metal in your duct work rather quickly. a friend of mine learned that after buying a house where the previous owner had done just such thing. $$$ to replace the furnace and ducts.

while this makes some sense I did not have an issue. mine is installed after the water softener and the furnace ran for over 20 years like that. Possibly as many as 27 years.

Very good humidifier company. It's installed on the furnace on the air return before your filter and blower. They tap into your cold water line and provide moisture that helps relieve dry noses and static buildup in the house. It uses minimal water and uses a small drain hose or pipe to your sewer. If you have hard water, take care to check this drain line periodically so it doesn't clog and leak water around the furnace. You MUST replace the filter every year or you're risking a mold problem, or the filter breaks apart and blocks the drain. Just turn it off in the warm months.
