With this humidifier, the high static electricity that comes with dry air, is completely under control, giving an assurance for the longevity of your wooden furniture, electronics, paintings and artwork.

The Aprilaire 700 has an automatic digital control. On setting it, it records the data entered and automatically raises the humidity level to where required without the need for monitoring.

The Aprilaire 700 is of a good size with a volume of 3168 inched cubed and a weight of 15 pounds. This humidifier comes with a water saddle and a 5 years warranty. However, some items need to be purchased separately which include duct tape, drainage tube.

Users' feedback

Users quotes on Amazon.comExcellent product has kept my 1614 square foot colonial at proper humidity all winter. I was able to lower the thermostat by about four degrees and save on my heating budget all winter. It tops in several areas: maintenance: the water panel is metal paper, so it does not break down & clog the drain, operation: it uses an outdoor thermistor to monitor outdoor temperature and adjust the rate of humidity accordingly.

Users quotes on Amazon.comExactly what the house needed with a new baby on the way! Spent many hours researching how to install a whole house humidifier and this one was recommended many times. When our furnace got serviced this fall the technician also recommended we get a humidifier and when I asked him which model this is the one he recommended. It's really hard to find anyone selling this unit because the manufacturer doesn't want just anyone to install it, they recommend a technician so I was pretty happy when I found it here on Amazon"

Conclusion: 700 by Aprilaire

The Aprilaire 700 Automatic humidifier is a nice humidifier which has the capability to serve the whole house. This makes it quite cheap in the long run when compared to buying several single room humidifiers for the entire house. It’s quite reliable and hardly breaks down. The fact that it doesn’t need to be refilled or monitoring makes it stand out.

However, the cost of purchasing it, purchasing a few extra parts, and the installation cost (which is not covered by the warranty), can end up being too high. Its water consumption rate is also way too high, but still manageable considering it’s used for the entire house.

For someone with a large tightly constructed house, this is the perfect humidifier to use. It’s a great humidifier to highly recommend you to purchase.
