Aprilaire 600 Whole Home Humidifier, Automatic High Output Furnace Humidifier, Large Capacity Whole House Humidifier for Homes up to 4,000 Sq. Ft.

Installing the humidifier went quite well. Since I have PEX on all my water lines I Tee'd into the piping and ran a line over near the solenoid valve and put a PEX shut-off at the end. The unit comes with a needle valve that is meant for copper pipe only. I had easy access to 120VAC for the transformer that supplies the solenoid valve. The humidifier drain was Tee'd into the 3/4" PVC drain line on the furnace. I put the outdoor air sensor for the humidistat on the intake of my HRV system close to the vent where it comes through the wall. I used 6" rigid duct and 90's to go from the humidifier to the return duct on the furnace. The unit comes with flexible 6" hose which I chose not to go with because the rigid won't have as much affect on air flow. I had to purchase the 18/5 and 18/2 thermostat wire needed to connect the humidistat to the furnace and solenoid valve and transformer. In summary I probably spent just over $100 on additional supplies ductwork, wiring and PEX pipe and fittings that was needed to install the humidifier. It took me a couple of days to put the system in and now it's up and running nicely controlling the relative humidity at 40%. So far I.m quite happy with the product.

I recently purchased the Aprilaire 600 Whole Home Humidifier, and I couldn't be happier with the results! Living in a dry climate, I've struggled with uncomfortable indoor air for years, but this product has truly transformed my home environment. Installation was surprisingly straightforward, thanks to the comprehensive instructions provided. Even for someone like me who isn't particularly handy, it took just a few hours to set up the Aprilaire 600. The build quality is excellent, and it's clear that this product is designed to last. One of the things I appreciate most is the automatic control feature. It maintains the perfect humidity level in my home without me having to constantly adjust settings. This has not only made the air more comfortable but also helped me sleep better at night and reduced static electricity, which was a common annoyance in the winter months. The performance is outstanding. Within a short period of time, I noticed a significant improvement in the overall comfort of my home. My skin feels less dry, my allergies have improved, and even my furniture seems happier with the added moisture. It's also a relief to know that maintaining the optimal humidity level can help protect my wooden floors and prevent them from cracking. In summary, if you're tired of dealing with dry air and its negative effects on your health and home, the Aprilaire 600 Whole Home Humidifier is a fantastic solution. It's reliable, easy to install, and delivers noticeable results. I couldn't recommend it more highly – it's been a game-changer for me, and I'm sure it will be for you too!

I bought this humidifier at a discount for being an open-box product, likely a return. It arrived with no missing or damaged parts and all the paperwork was there. My home is 2625 sq/ft including the basement and the next smaller model would have been sufficient. However, I have an on-demand electric water heater and the humidifier doesn't flow enough water to kick it on (thankful for that energy savings). Since the only hot water entering the humidifier would be what little is in the main hot trunk, I got the next bigger model to make up for using cold water. Installation was a pretty simple DIY project for someone that has the tools and can read directions. Tin snips, a holesaw kit, wire strippers, and some screwdrivers was about the extent of it. Having access to your furnace and thermostat owner's manuals is helpful as well. I set the humidistat up for auto humidity control using the outdoor temp sensor but without auto fan control since the unit will see mostly cold water. I mounted the outdoor temp sensor in my furnace's draft inducer fresh air pickup pipe just inside the band joist per the alternate mounting location instructions in the manual. On startup, the unit kicked on with every heat call to the furnace until my house went from 31% RH to 45% RH in about a day. Just a few days ago here in Michigan, outdoor temps dropped to 18-deg at night and the humidistat compensated by dropping RH to 38%. I have since adjusted the dial up and down, adjusting the target RH in auto mode, found the point where my windows just start to condensate, and backed down one notch from there. After operating this unit for over a month, I have verified its RH accuracy with another hygrometer in other rooms of the house. The humidistat's auto control has been spot on thus far, keeping the highest RH in the house without allowing condensation on the windows. My family has noticed our dry sinus issues have improved and I have noticed that my furnace runs less as the humid air is easier to heat.

Needed a humidifier for new-to-us house and picked this one. Did the installation myself and it took a few hours (although if you are not comfortable with electrical, ductwork and plumbing probably best to hire someone to do it). Need to buy some 1/4" copper line, some plastic water line to get to the drain, some flexible ducting and furnace electrical wire as well as associated tools to cut/install/secure these items. It has worked quite well during the winter, water usage is not too much (except at initial start-up, it was continuous for a few days until the humidity got back to what it should be), the control panel is easily visible and control knob makes it easy to change the setpoint. The humidity level on the panel reads a bit different than our nest but probably due to different locations and temperatures. We had a rotating one at our previous home, big upgrade with this one. Does not get as clogged with calcium, it self-drains and can adjust humidity based on outside temperature (no more frost on windows!). Overall nice system but i would caution, for most it will not be a diy install.

Been using this for about two years an have had no issues, had to change filter cartridge every year as per maintenance on it. Works great would recommend to anyone.
