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!

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.

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.

Installation was easy, and the unit operates quietly, ensuring a peaceful environment. The large capacity covers the entire home effectively. Maintenance is straightforward, and the unit significantly improves indoor air quality, making it a worthwhile investment for a comfortable and healthier living space. Highly recommended! The only drawback encountered was the digital display unit requiring rewiring with a transformer to function, a minor inconvenience in an otherwise excellent product.
