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

The product itself: 9/10. Humidifies like the beast that it is. No leaks, no issues with it out of the box. One note is the controller unit could be better with showing target humidity, and show relative outside temp. The installation instructions assume their target audience knows what they are doing and knows how to read technical diagrams, which by that standard they are pretty fine. For other audiences, they might struggle with the assumptions the install instructions make. The install: For context, I’m an average DIYer. This was one of the harder DIY projects I have done on my house. It’s plumbing, electrical, and HVAC all in one project. You will be cutting metal, running wires, and running water lines. You will likely be spending at least half of the units cost on materials to install it, especially if you prefer copper water lines. The adjacent install kit is a waste of money if you want good materials for this unit. I come with a couple of recommendations: * if you have an older house, get your attic insulation sorted to retain heat well before this humidifier project. If your furnace has to run A LOT to keep up with the warmth of your older house, even this humidifier may not be able to keep up to the humidity level you need. * Wire the controller to the return first. This can be done independent of installing the unit and doing the water line. * do not use the solenoid that comes with the unit. They are notorious for leaking and not lasting the lifetime of the unit. Spend the money to get a better setup that will last you longer. * I also highly recommend using the same waterline material as coming from your water heater (likely copper or pex). * set up your water line second. This can also be done independent of the unit being mounted to the air supply. * wear long sleeves while cutting the metal for mounting the unit. It’s very easy to cut yourself. If you’re looking for a DIY adventure and a way to improve your own skills, this product is quite the challenge.

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!

Very impressed with the product and the quick delivery. All Installed and works as a charm.

I have wasted a lot of money on home humidifiers. Nothing has been successful until now. If you are looking for a first-time purchase or replacement, don’t consider anything other than the Aprilaire 700. Here’s why: Humidipads Do Not Work Flow through humidifiers cost approximately $100.00 per month in wasted water Ceramic drum humidifiers require major maintenance and do a minimal job Steam humidifiers are a little better if you can afford the operating cost. My hydro bill increased nearly $100.00 per month ‘Regular’ humidifiers rely on air movement from the heat exchanger to get into the pad and move some moisture through the by-pass and ultimately into your home. This results in a filter change every two months (at approximately $12.00 each) so it doesn’t plug up and lose efficiency (which is only minimal at best). For my money, I just found the best for me. I purchased an Aprilaire 700 from Amazon.ca, spent a couple of hours replacing a 400M model which was not a good buy, and now I am the happiest guy around. On setting ‘5’, I have 35% RH in my 2200 square foot two-storey home and my hardwood floors are happy again. I checked the digital automatic humidistat several times a day and when the RH reaches 33%, the system turns on until 36% at which time it rests again. Love it and know you will too. I do not work for or know anyone at Aprilaire. This is an honest evaluation and personal testimony. I forgot to mention the real reason this is a superior product that REALLY works. It is fan powered and forces the moisture from the Water Panel into the furnace for peak efficiency. The panel requires only annual service (not bi-monthly).

After years of trying to increase humidity during the winter months using portable ultrasonic humidifiers, we finally purchased the 600A model for the furnace. Can't believe i waited so long now that I have the whole home unit installed. On a cold Alberta day, without humidification we would see humidity levels inside the house of 15% or lower. Obviously not the ideal levels during the cold and flu season, or for wood shrinkage of trim, floors, etc. Install is fairy easy if you have the correct tools and some general knowledge of electrical work. I installed the unit on the return air plenum due to space restrictions and then piped the bypass into the supply side, well above the AC condensing coil. Outside temperature sensor will require drilling through an outside wall to pull the wire through. Don't rush the install. Make sure you cut the template precisely into your furnace plenum because there is not much room to screw into the sheet metal if you cut the hole too large. *I opted to NOT use the provided saddle valve because of they're prone to leaks. Instead, I used a 1/2"×1/2"×1/4" Sharkbite fitting with its own shut off valve. You'll also need to buy additional thermostat wire (4 wire) to complete the wiring from the furnace control panel to the humidifier controller. I needed to buy a couple 90 degree elbows and a longer 6" diameter semi rigid duct hose. After installation, the unit ran continuously for approximately 3 days to bring humidity levels up to 40%. The-25 Celsius weather obviously didn't help, as the furnace was running a heating cycle quite often. The unit maintains 35-40% humidity automatically in our home with the dial set at 4. I keep my furnace fan running 24/7 to ensure constant supply of fresh air and help with heat distribution from main floor to basement. Overall, very happy with the performance and how easy it now is to maintain the humidity level inside our 3300 sq ft of living space.
