Description

AprilAire introduced the first evaporative humidifier for forced air furnace systems back in 1954. Since that time, AprilAire continues to lead the industry in whole home humidification systems. Our evaporative humidifiers work by piping water into the distribution tray located at the top of the humidifier. The water is uniformly distributed across the width of the tray and through a scientifically designed system of outlets. It flows by gravity over the Water Panel evaporator. Dry, hot air from the HVAC system is moved through the moisture-laden Water Panel evaporator. Natural evaporation takes place, the water is turned to vapor, and the humidified air is circulated throughout your home. INCLUDED IN THE BOX: Installation instructions and template, humidifier with built-in fan, 24 VAC transformer, automatic digital humidifier control with sensor, outdoor temperature sensor, saddle valve, solenoid valve, and Model 35 Water Panel

    • Please read for Carrier furnace and thermostat
Style: Humidifier
Review Image by xavier xavier
** 2 year update: I still love this humidifier it has never caused me issues that required replacement parts. The only maintenance i've done is changing pads every 6 months to a year and wipe down the inside with vinegar water to clean it up. Also twice the small orfice clogged causing water to slow or stop and humidity to drop. Easy fix with a small wrench and needle. ** Original review: First of all, this humidifier is a lifesaver. It works amazingly well. But I'm reviewing because I want to help buyers who have a Carrier thermostat and furnace. My Carrier Infinity Touch thermostat did not use all the standard wires that most thermostats use. The wiring instructions for this unit did not apply to my system at all unfortunately because my Carrier thermostat was wired up with just 4 wires: +power, -power, data+, and data-. At first I thought the install wouldn't be possible because of the wiring but then I realized that my furnace computer board had a "hum" pin on it. In my case, the output was 24v AC, which is exactly what the Aprilaire unit was expecting in order to trigger the relay to activate humidification. So What I did was plug the two loose wires from the humidifier directly to "Hum" and the "C" terminal on the furnace. WARNING: Not all furnace "hum" terminals are 24v AC, so you need to make sure your unit has the correct voltage on that pin before doing that. Because the wiring was this way, my thermostat had to directly control the humidifier, so i did not use the aprilaire humidistat that comes with it. The most trouble in the whole install that I faced was that initially, my Carrier Infinity Touch thermostat would not allow me to control the humidity. At first, all the humidity settings were greyed out so I couldn't click them. If this happens to you, you need to enable the humidifier "accessory" on the thermostat. This is how: Go to the main menu on your thermostat (dont try this on the phone app), then click and hold the "service" button until it turns green (about 10-15sec). Then you should see a hidden menu that the technicians are supposed to use. From there, go to "setup" then scroll and click "accessories". Then click "humidifier". Now you can tell the system that you have a humidifier plugged in. You can also set a reminder for 6 months or a year or whatever to change your humidifier filter. The other option "humidifier with fan" is a little bit vague but i have it enabled and it works how i want it to. If the humidity drops down, the furnace fan and the humidifier both turn on, even if the heater itself is not heating. This was my desired feature. Now you will be able to control all those settings for humidity that were greyed out before. I highly recommend enabling "window protection" if you live in a cold climate. Because this humidifier works really well and it will cause some condensation on your windows (especially upstairs) if you are not careful. Humid air rises! Check your windows and keep an eye on them because if they get moisture on them that means your attic can also get moisture and you really don't want that. I Hope this helps at least one person! Thank you Aprilaire! P.S. I had no water flowing on my humidifier after the first install, but i realized there is a tiny yellow restrictor hole that got plugged with something so i stuck a fine needle in it and water works fine now. I Haven't had an issue with that since. The restrictor is just after the solenoid on my 700 model. ... show more

    • One heating season was enough, this thing is way too loud.
Style: Humidifier
I picked this up after swapping out to a new 96% 2 stage furnace with VS motor. I couldn't use the bypass style I had previously since I needed to significantly increase the return side of the ductwork and was very limited to where I could mount it. I heard good things about these fan powered humidifiers and wanted something I could install on the supply side, so decided to give it a shot. It does a great job getting the house to a nice comfortable humidity level, and I like the automatic humidistat they supply with the kit. However, it is just too loud for my liking. The new furnace purrs like a kitten, you can barely hear the thing run. But when this humidifier fan kicks on, you can hear the solenoid hissing and fan noise in every room in the house. In addition to the noise, I'm also tired of seeing so much waste water just trickling down the drain every winter. I'm currently leaning towards installing a mini mister style humidifier even though they get mixed reviews. I'm willing to take a chance on the mister as they're quiet, don't require a water panel replacement at certain intervals, and also don't trickle water down the panel and into the drain at every call for heat. If noise is a concern and your furnace is close to your living space, I'd probably be looking for better options than this. ... show more

Review Image by G Taets G Taets
My house was sitting at an indoor relative humidity of 18% the other day, and I was tired of the static, dry skin, loose floorboards, and bloody noses, so I decided It was time for a while home humidifier. I researched and decided on the Aprilaire 700. Install took me about 4 hours including a trip to the hardware store. I’m an experienced DIY and a lifelong mechanic, so it may take longer or shorter do to experience levels. I installed this on the return side of my heater due to size constraints on the supply side, but the RH has been rising steadily over the last two days with no issues. I did buy from AmazonWarehouse in “like new” condition, even so, I was expected something missing or damaged, but was pleasantly surprised that only the butterflies that tighten the sides of the frame to duct to be missing (not a big deal as the frame is still secured to the duct with screws (which are not included). Items I need to complete the install: 18/5 and 18/2 thermostat wiring Sharkbite valve to 1/4” o.d. copper line 1/4” copper tube 1” Zip-In screws Foil tape Something I hadn’t thought about was the 110 vAC to power the internal fan: The cord is only about 5’, and my outlet was about 6’ away, so I had to add an outlet closer, which added additional time. I have a Honeywell smart thermostat, which doesn’t have humidifier controls (that I know of), so I used the wiring described on the install sheet. The only deviation from the instructions, was there was already a 24 volt transformer on the side of my heater so I just used that for the solenoid power instead of the one supplied with the unit. I set the dial to 7 and let it go...it’s been running for 48 hours pretty much non-stop to bring my house up to 31% RH and rising. I assume once the house absorbs the humidity it’ll stabilize and only cycle when needed. My animals are not staticky, my skin is soft, my nose isn’t dry, and I was able to take my heater down to 70 from 73 and still feel comfortable! I highly recommend this unit. ... show more
