Description

TrueEASE humidifiers run water and air through the system when humidity is needed; using less water and saving energy by eliminating the constant cycling of air, saving customers water, energy and money. Plus, since humidified air feels warmer, customers can turn their thermostats down to help reduce heating bills.

Thanks to TrueEASE's patented design with multiple snap-into-place configuration options, obstructions such as pipes or compact spaces with tightly fit water heaters will no longer complicate installations.

Features:
  • Up to 50% Water Savings on Advanced Fan-Powered Models - Timer-metered solenoid wets the pad only as needed, reducing water waste by as much as 30% and savings up to 10,000 gallons of water per year
  • Quietest Residential Fan Humidifier - The centrifugal wheel and propeller fan design makes TruEASE quieter than standard variable HVAC systems and more than 20 dB quieter than equivalent competitive residential fan humidifiers
  • One-Piece Design - Mounting screws are located around the perimeter of the humidifier, making it easy to install in a single step rather than mounting a separate frame assembly.
  • Integrated Wiring - Push terminals make TrueEASE simple to wire and the integrated control board eliminates cost and time spent on separate relays typically required to deliver additional humidity by forcing the fan. Simply flip a DIP switch to set advanced humidification options.
  • Quick-Connect Plumbing - All plumbing is connected in a single step by attaching the hose to the quick-connect gasket
  • Familiar Footprint - Installs in the same space as existing bypass humidifiers for easy retrofit upgrades. A foam seal ensures a tight fit
  • User Friendly Pad Access - Easy slide-out design means there's no disassembly of the humidifier or interaction the the plumbing needed to change the pad

This is the ONLY fan per unit to use!!

I while I did not buy from here I've installed a ton of these for customers. You need a 21x21 hole. Where this unit shines is it allows me in tight spaces where you have to mount the unit high. Unlike the other brands you can do that because you have to be able to get the front panel off / which is the fan assemble cover off. With this unit it's a simple as sliding the front door out which is fantastic design. These units are very very quite. The added bonus is it comes with the drain hose, saddle valve, and water hook up line. Aside from thermostat wire. It cut the hole, which will be oval, hook the water up and drain, plug it in and your good to go. The only small grip I get from some customers is if you set it at 40% it may not shut off. I tell them set it at 35 and it should cycle as needed which it does. It's light weight and can be mounted to ductboard supplies with minimal reinforcement to support it from the back side. Overall from a personal use to my customer to whom I sold and installed this there just a really solid unit. And preform better the way pulsate the water / wicking the pad not just dumping huge amounts of water like the other brands. Plus the added bonus is the nice digital humidistat they include. It a nice touch when you open the box and go wow it's all there. As in oh need a hose clamp, water tube drain line. It's all there. Which is really nice.

Great for humidification but poor design

This unit does a great job pumping out humid air. My gripe is with the way the unit is designed. If you have a sealed system this unit will destroy that seal. The vented fan causes 2 problems: 1. When it is running the fan pulls air in through the vents you see in the photograph. I can't think of many HVAC locations where you'd want an air intake right there. And there's no connection it to duct it into the return or another fresh air source. 2. When the unit is not running your heat (in winter) or cold (in summer) blows back out those same vents, so you end up heating or cooling the space around the HVAC. Very poor design with this unit.

I did buy this product again.

This is the model I had installed in my heating system. It can raise the humidity 1% an hour. The fan blades (squirrel cage) broke and there was no replacement un less you purchase the motor too. So for a about $200 more I got the whole brand new unit. Best part was I put it in place put in a few screws hooked up water amd turned on, hooked up drain plugged it in and hooked up humidistadt and it was indtalled no new cutting or anything. It does tend to leak out the overflow happened once before. Makes a water on the floor.not sure why the old one did it too. So I now have a bucket under the overflow. Brand new filter. It leakedbefore and changing the filter stopped it. I am Using honeywell filters.

Simple, Effective, Quick.

I have installed 8 of this model for customers starting in 2023, until now (Q1 2025). It is a very easy to use and easy install for what it is, easy to wire and the kit comes with everything you need. Saddle valve, water line, humidistat, outdoor sensor, everything. Make sure you mount it level for drainage purposes, otherwise its very basic to install.

Hot water humidifier! works good

I got this running with a vision pro 8000 thermostat. 3000 sq ft house, maxed out at 39%, set to 45%. Plenty of connectivity options. I like it. It's better than the 23% I had before.

I would not buy this item again

Item arrived twice, once physically damaged with capacitor that had come off the control board, and the next one would not power up at all.

Best whole home humidifier for larger furnace applications!

I had to replace our 25-year-old furnace last October. I had an equivalent April Air 700 model that a local HVAC contractor sold and installed 15 years ago. Although the April Air did a decent job when it worked, it was very poorly designed, cheaply built, and I had many problems with it over the years such as the blade fan failing twice, the humidistat was inaccurate, water wick was difficult to change, and the plastic housing became very brittle and cracked within in a few years' time. Upon researching a new humidifier to install in our new furnace I noticed that all the 16–18-gallon fan models available are designed the same as my 15-year-old April Air model# 700. That is when I noticed & purchase this Honeywell, HE300. It has been installed and working for a month now & I couldn't be more pleased. The unit was easy to install, very quiet squirrel cage fan operation, digital display very accurate humidistat, east to access and change water wick, and a very well-constructed and designed housing. The only problem was the provided drain hose is unusable because it is too thin walled so it will easily kink. IMO this is the best designed and operational unit in its class right now. Supply House has by far the best price on this unit, and they had it to me in two days with free shipping. I would highly recommend dealing with them! I don't participate in very many reviews, but I will always give credit where credit is due. THANK YOU

Product is great Supply House is even better

The humidifier works as expected and suits the needs of humidifying the house. It's quiet, it's efficient and was easy to install once I figured out the wiring. My house is much more comfortable after installing. Now for the service: My first delivery arrived damaged. I contacted Supply House and they immediately sent out a replacement with improved packaging and made the replacement a snap. Two thumbs up for the great service – I refer everyone I can see you guys!

Q: Does this model include the humidistat?

Asked by Chris 10 years ago

Add your answer

* Required Field
-

The first page of the installation instructions shows the contents of the humidifier box including the humidistat (item "G"). This is a basic 'stat that's best mounted on the return duct (assuming you're buying the fan-powered and not bypass model). This 'stat doesn't compensate for outside temperature so you will have to adjust the desired inside humidity setting based on your outside temperature.

Q: How much clearance is needed to remove pad and install new pad on the fan powered model?

Asked by Craig 10 years ago

Add your answer

* Required Field
-

The pad, in its frame, pulls out straight from the back of the unit. You have to pull the frame all the way straight back to clear the body of the humidifier. The clearance needed behind the unit is 12" minimum.

Q: Should you hook up the water supply to the hot or cold water?

Asked by Bob 12 years ago

Add your answer

* Required Field
-

You can use either hot or cold. If the humidifier only runs when the heat is on, it won't matter. Hot might help when only using the fan with the humidifier. I connected to cold.

Hot. Hot water vaporizes easier. It like having a steam humidifier. Only lazy installers use cold water.

Q: What should the humidity be inside a home. Will this work on any Heat and air unit.

Asked by Tommye W 12 years ago

Add your answer

* Required Field
-

What should the humidity be inside a home? Generally, the relative humidity should be between 40% and 50%. Will this work on any Heat and air unit? It's not possible to state if it will work on any heat and air unit because of all the variables associated with each system. You must compare the requirements of the humidifier with your specific system. From the HE-350 Honeywell manual, the following requirements must be present in your system to successfully use this humidifier: -Access to supply side duct. You can't mount this on the return side duct. -Ambient Temperature 34-90 degrees (F). -Access to cold or hot water supply pipe; floor, or other, drain; and 120VAC power receptacle. -Mounting surface must be able to support weight of humidifier (about 16 lbs). -Must be mounted on a vertical surface, level and plumb (you can't turn it sideways for example). -Ensure mounting area allows access to remove/replace unit cover and also humidifier pad -Unit needs to extend into plenum about 1-3/4" (check clearance to air conditioner evaporator coil (if present) -Humidistat mounts on return duct. -Generally compatible with 24VAC control wiring. Connections to heating system depend on your system.

Q: Is it OK to mount it horizontally. I have only space on the top of supply right above the heating unit.

Asked by freecat 12 years ago

Add your answer

* Required Field
-

No, the water source feeds into an open pan that trickles the water down through the filter that air is blown through. If the unit was on its side it would just leak water out of the side of the unit onto the ground. Sent from my iPad

Was this review helpful to you?
-

No, the unit has to be mounted as shown in the photo, plumb and level. It depends on gravity for proper water flow.

Was this review helpful to you?
-

No. If must be vertical. The water needs to flow down the pad.

Was this review helpful to you?
-

No - the water supply relies on gravity to pull the water down through the pad. If you mount the unit horizontally, the water will never enter the pad and will just leak into your HVAC ducts.
