    • Wish I had purchased Years ago
Style: Dehumidifier
Wish I had bought the Aprilaire years ago. Two ways to run this Dehumidifier. You can run it stand alone or connect to your house central system. If you're mechanically inclined you can set this unit up to your central system on your own, otherwise you can pay a heating & air guy or an electrician. I intended on connecting to the central system but when it arrived during the worse part of the year humidity wise I plugged it in, turned it on and set it to the percentage I wanted and it worked so well in the central closet that I haven't bothered to connect into the house system. It is downstairs on the main level and actually takes care of the entire house. Since its in the heating/air closet I just turned the unit so the drain pipe that drains the water is turned toward the drain in the floor and I've had zero problems. When fall arrives I just turn the unit off because humidity is no longer a problem and there is no need for it to cycle unnecessarily. Turn it back on end of April or in May. Noise wise since it's near the living room, not a problem. About the same noise level as the a/c running. The relief it has brought with dehumidifying the house makes any noise it may omit more than worth any noise inconvenience. Actually the only time I notice the noise is when fall arrives and the central air is turned off; the noise from the unit turning on to check the air humidity is the only time I notice the unit. That's when I turn it off for the year. This is an investment. An investment in comfort. One of the best decisions I've made for the house in a few years. I've been able to bump up the thermostat a couple degrees also. Yeah, keeping the a/c set to settings before I installed the unit makes the house a little chilly at night. Oh, I have a portable dehumidifier upstairs where humidity of course is the worse that I had used for years. The kind you have to empty the water out of the catch basin. That's been turned off. Unplugged. And in a corner since about 2 or 3 days after receiving and setting up the Aprilaire. Not needed anymore. The Aprilaire took that unit's job away from it fair and square. Note: the Aprilaire is 'downstairs' and the portable is 'upstairs', and the Aprilaire - stand alone - out performed and took away the need of a very good unit. The Aprilaire can be portable if you install the wheels. ... show more

    • Fantastic and high quality
Style: Dehumidifier
I cannot say enough good things about this little dehumidifier. When I first installed it, it ran continuously for probably a day or two, maybe even three. It is integrated into my HVAC in a return to supply configuration and controlled by my Nest learning thermostat, which has its own humidity sensor. While that is convenient, however, Nest settings graduate in increments of 5%. If I had to do it over, I would have left the dehumidifier sensor to control the dehumidifier and signal the HVAC to turn on the fan. I put it in my basement (poured concrete) to keep it dry. During humid months it would go between 55-60%, which was too humid for me. I bumped it down to 45%, which is perfect. If you have ever had a standalone low-end dehumidifier, this is NOT that. While they certainly work, and I’ve used them before, there is simply no comparison. You get what you pay for. My E100 has been operating without a hitch for 9 months. I love it so much, I’m putting an E130 in my attic to dehumidify my main floor and 2nd story. I will definitely configure that one to use the internal sensor and the HVAC fan. **** After 9 months of operation **** I installed the E130 in my attic, and ducted it as return to supply, just like the E100. I also commissioned the new E130 dehumidifier using its internal humidity sensor rather than integrating it into my Nest thermostat. I no longer believe this is the best configuration, even though the Aprilaire’s sensor has a sensitivity of 3% vs. Nest’s 5%. The main observation I would offer is that humidity within the living space differs enough from the humidity in the ductwork that difference in the precision between the sensors is meaningless by comparison. With the internal sensor sampling air within the ductwork, the humidity of the air sensed appears to be influenced by the local proximity to the moister air surrounding the air handler’s drain pan therefore skewing the reading. All of this is in spite of a three minute sampling routine that presumably would flush out any local duct air and replace it with air from the living space. Now, perhaps this reaches some equilibrium over time. For example, perhaps the dehumidification cycles eventually completely remove all drain pan moisture such that the internally sensed humidity from the ductwork no longer differs from the air from the living space. While it may be a nice experiment, I won’t be waiting around to find that out. I plan to have the E130 connected to the Nest thermostat, as the final configuration. All that is to say, the initial Nest thermostat integration of my basement E100 was the correct way to do it. I just need to correct my second dehumidifier (E130) to match it. ... show more

    • Buy American
Style: Dehumidifier
I bought the Aprilaire EO100 after doing research about crawl space encapsulation and humidity control. Yes, there are less expensive dehumidifiers but the ease of installation, high level of design and features, online installation videos and promise of telephone support from Americans convinced me. It didn't hurt that the eo100 was discounted $300. I have no love for Chinese designed products. They are a poor substitute for American designed products. I installed the unit on cinder block in my workspace adjacent to the crawlspace as a trial and used a plastic bin to collect water will I figured out how to handle the condensate line. I ran the unit for about 5 hours and it dropped the humidity in my workshop, the size of a one car garage from 72% to 66% humidity with the full size walk-in crawlspace door open. Crawl space itself is less than 2000 sq ft, closed off from the outside with plastic covering on the dirt floor, covered vent openings and Dry loc on subterranean walls. The unit is extremely quiet. It did take some time before water dripped from the condensate opening but once it got started it dripped out continuously. I'm very pleased with this purchase. ... show more
