There are lots of concerns that arise in dry weather conditions as well as when the winter season approaches. Not only does cold weather make outdoor life quite intolerable, but also causes a widespread of health issues such as running nose, fever, dry skin, itchy eyes, raspy throats, flu, and dry lips among other conditions. One significant cause of such predicaments is the low humidity level in your indoor space. So, to solve this problem, you need an effective whole-house humidifier like the Aprilaire 800 Whole House Steam Humidifier to help alleviate this symptoms and improve overall comfort in the home.

A steam humidifier like the Aprilaire 800 Whole House Steam Humidifier works the same way as a traditional humidifier except that they come equipped with a humidistat instead of a thermostat which they use to sense the humidity levels in the home.

While a thermostat is ideally used for measuring temperature, a humidistat measures the moisture in the home. So, once it senses that the humidity levels have dropped below a certain set point, an alert is sent to the steam humidifier unit to start raising the humidity level in the home by pumping moisture in up to the desired levels. It does so by heating water in the reservoir, converting it to steam and releasing it into the air. 

By doing so, it’s able to effectively control the humidity levels in a process that also helps to filter out odors, toxins, chemicals, particles and other impurities that could otherwise result in unhealthy quality of air. You instead get numerous benefits including reduced allergy symptoms, prevention of respiratory illnesses and most importantly, the indoor living space becomes more tolerable than ever before. 

Although steam humidifiers are not as popular as their evaporative counterparts, the Aprilaire 800 Residential Steam Humidifier is no doubt one of the best steam humidifiers for residential homes out there, due to its efficiency and powerful performance.

A product of the popular makers at Aprilaire who have more than 50 years of experience in the indoor air quality business, this is one of their most popular whole-house dehumidifiers, ideal for maintaining healthy humidity levels throughout all the rooms in the home during the colder months as well as the drier climates.

So, if you’re a potential buyer looking for in-depth information about this humidifier, please sit up and read on.

Why choose the Aprilaire 800 Whole House Steam Humidifier?

Steam humidifiers like the Aprilaire 800, are now becoming increasingly popular due to their efficiency, reliability and low energy usage. Although they may require a notable upfront investment (due to their high price tags), steam humidifiers have lots of great benefits and are accompanied by numerous positive feedback from most customers.  Aprilaire 800 Whole House Steam Humidifier

The Aprilaire 800 on its side was specifically designed to humidify homes during the cold months or homes located in arid or semi-arid geographical regions. This unit can cover large rooms with dimensions of up to 6,200sq ft. The 800 model uses the electrode technology to operate which according to most customers is efficient, easy to install, and easy to maintain.

For those who are curious to know how this appliance operates, the Aprilaire 800 simply uses electrodes which are submerged in a replaceable canister. When the unit is switched on, electric current flows through the electrodes causing a resistance between the water and the electric current. This forces the current to heat the water resulting to steam. Once the humidifying season is over, it’s highly recommended that you replace the canister alongside the electrodes.

If you’re a fan of steam humidifiers, you know that some units in this category can’t operate without being connected to a HVAC system. Luckily, with the Aprilaire 800, this requirement has totally been eliminated as this humidifier can perfectly run independently without a HVAC system.

Features of the Aprilaire 800 Whole House Steam Humidifier

1. Electrode technology

One of the most impressive features of the Aprilaire 800 is the electrode technology. Here, electric current runs through two electrodes submerged in a replaceable canister with unfiltered water. Since the water is not pure, the impurities will catalyze resistance between the water and the electric current heating the water to foam steam.

This process is energy efficient, and user-friendly as the steam produced is environmentally safe and good for humans to breath. Also, the cost of replacing the canister and the electrodes is relatively low as you don’t have to clean or scrub the appliance.

2. User-friendly interface

Although not all, some humidifier models you’ll come across have complex control options that are very difficult to use. Luckily, in the case of the Aprilaire 800, the user interface is intuitive and very fluid making it easy to view and operate.

The control panel features a power button, a fill icon with an indicator light to notify you when the unit is filling, a steam icon with an indicator light to signal when the unit is dispersing heat, a drain icon with a light to notify you when it’s draining and finally, a service icon with an indicator light to signal when the canister needs replacement.

3. Dual sensor automatic mode

The Aprilaire 800 is engineered to operate both manually and automatically depending on your personal preference. However, the auto-mode is more astounding as it allows this humidifier to monitor and respond to humidity fluctuations in your indoor space relative to outdoor temperature to determine the amount of humidity it can release. You simply program it to desired levels and forget it, it will do the rest for you.

In addition to that, the auto-mode function notifies you when the humidifier is releasing heat or draining water. It also automatically drains the steam canister after being in operation for 168 hours paving way for canister replacement as you prepare for the next cycle.

4. Digital humidistat

This unit allows you to take advantage of the digital humidistat to balance the level of steam in your indoor space. At least with the humidistat, you’ll be able to maintain an optimal humidity level of 35%-45% which is considered best for reducing respiratory infections.

Furthermore, the digital humidistat is fitted with a blower activation switch and an outdoor sensor which accurately detects the amount of humidity required in your indoor space based on temperature fluctuations. With such advanced technology, the Aprilaire 800 will take out any guesswork relating to humidity settings to make your life easier than ever.

Benefits of the Aprilaire 800 Whole House Steam Humidifier

1. Easy to install and operate

One of the things any potential buyer will look at when shopping for a humidifier is the installation and ease of operation. Here, Aprilaire has done their homework pretty well. First, they’ve designed this unit with an easy installation procedure though it must be accomplished by a professional such as an authorized technician.  Aprilaire 800 Whole House Steam Humidifier

The process of screwing the humidifier on the wall is pretty easy. Also, the process of connecting the unit to your home’s water supply is simple though as I mentioned, it should be done by professional personnel.

As for the operation, the Aprilaire 800 features a user-friendly control panel that gives you an explicit view and access to all features. Whether you like it manual or automatic, this humidifier gives you the freedom of choice keeping in mind it has multiple sensors that make it more “intelligent”.

2. Low maintenance

Speaking of maintenance, the Aprilaire 800 will not require you to break the bank for you to maintain it. With the help of an expert, all you need to do is to install the unit then connect it to your home’s water supply. Since this humidifier uses running water, you won’t have to worry about bacteria and mold build-up in the system. With such a huge advantage, you don’t need to regularly clean the unit.

Also, the cost of replacing the parts is generally lower as the Aprilaire 800 Whole House steam humidifier doesn’t include lots of replaceable parts. However, the only area you’ll need to take care of is the canister which must be replaced at least once every year.

Finally, the Aprilaire 800 is designed to use any type of water be it hard or soft. With this advantage, you don’t have to worry about purchasing water softeners which again minimizes installation complexities and operating cost. In fact, it’s highly recommended that you use impure water as it has ions that promote rapid transfer of electric current.

3. Powerful performance with high room coverage

The Aprilaire 800 is a high power capacity type of steam humidifier primarily intended for whole-house use. It’s able to deliver effectively maximum levels of humidity throughout all the rooms of your home, distributing up to 34. 6 gallons of humidity per 24 hours, based on voltage and installation. This makes it ideal for large rooms with dimensions of up to 6,200 sq ft. So, whether your home is tightly built or highly ventilated, this unit will do a perfect job of humidifying your indoor space.

The Aprilaire 800 steam unit is a perfect choice for typically inaccessible parts of the house such as the attic and crawl spaces. It’s also a great complement to other heating sources such as heaters and air conditioners thanks to its high humidifying capacity.

4. Doesn’t require a HVAC system

One advantage of the Aprilaire 800 steam humidifier is that it doesn’t require a HVAC system to operate. This unit uses the absorption and dispersion steam technology to disperse steam through the airflow system without causing any condensation problems in the ducts.

Since the unit can operate independently without a HVAC system, you need to employ a professional to do the installation for you to ensure that the humidifier is connected to the existing ductwork and that the drainage tubes are perfectly fitted to prevent condensed moisture from leaking and damaging the ducts.

What’s not so good?

1. The warranty

Although the Aprilaire 800 is backed by a 5-year limited warranty, connections must be done by an authorized technician or else the warranty will be voided. Most customers have really complained about this approach as they feel the installation process is easy enough to be accomplished by anyone.

However, if you want your warranty to be honored in case of anything, professional installation is non-negotiable.

Customer Feedback

Most of the customers who’ve chosen the Aprilaire 800 Whole House Steam Humidifier are generally homeowners living in arid regions or those living in places that record very low temperatures during the cold winter seasons. Most of them have appreciated the efficiency and how fast it’s able to raise the humidity levels.

Customers living in cold regions have appreciated the performance of this unit as it’s capable of dealing with dry air/low humidity with ease, while people who suffer from cracked lips, itchy eyes, and raspy throats have also appreciated this humidifier with some calling it the “best investment ever”.

A fraction of customers living in Colorado  and other drier areas have appreciated how fast this humidifier increases the humidity level in the room. One customer stated that after installation, the Aprilaire 800 took only 12 hours to maintain a humidity level of 37-39%.

The Aprilaire 800  steam humidifier as expected, has also received a number of negative criticisms from a fraction of customers due to its high operating cost. Compared it to the evaporative Aprilaire unit, one customer stated that this unit uses about 1,600 kWh a year while the former (the evaporative Aprilaire) uses 600 kWh in almost 2 years.

Still, on the high operating cost, several customers have complained about the high cost of purchasing this humidifier as well as the higher cost of replacing the parts such as the drain valve and the canister.

Several customers have confirmed, much to their dismay,  that Aprilaire will not honor the warranty if you install the unit yourself. For the warranty to be upheld, installation must be done strictly by a professional, regardless of how simple and easy the whole installation process is.


Steam humidifiers are fast emerging and gaining dominance among most homeowners for whole house applications where evaporative humidifiers are less practical. If you’re one of these home owners, the Aprilaire 800 Whole House Steam Humidifier is the perfect choice for you, to help protect your home interior and infrastructure from the damage that could be caused by low humidity as well as to help alleviate dry air symptoms.  Aprilaire 800 Whole House Steam Humidifier
