Best Whole Home Humidifier 2017

The best whole home humidifier is a unit that is designed to provide the ideal amount of moisture to your home, thereby reducing the ill-effects of dry air and making you comfortable at low thermostat settings.

Benefits of using whole house humidifiers

It is a well-known fact that a certain level of humidity is required to keep the atmosphere healthy and balanced, particularly inside the home. Humidity levels under 35% can seriously impact your health with dry air extracting all the moisture from your body, making you feel colder and giving you dry skin and making you prone to infection. It also makes you sick and prone to allergies and asthma.

By installing the best whole home humidifier, you can also get rid of any mould deposits, thus making your home a healthy place to live in. Humidifiers have plenty other benefits, such as:

  • Convenience: Once you set up your whole-house humidifier, all you need to do is to set the humidity level and leave it to function. These devices measure humidity with a hygrometer and it automatically humidifies the air as your furnace works to warm it up, thereby distributing it to all the rooms of your house via your duct work.
  • Humidity Level: A whole-house unit constantly monitors the house’s indoor humidity level, and adds moisture when required and limits the humidity level to the chosen setting. There are several room units that do not come with regulators that can stop humidifying the whole house when the pre-set humidity level has been reached. However, this is necessary as excessive humidity can cause mould, mildew and dust mites.
  • Maintenance: All parts of a room humidifier must be cleaned to prevent mould and bacteria deposits. But a whole house humidifier needs to be cleaned just once or twice a year to clean white dust mineral deposits left by steam. Apart from this, it does not need any other maintenance.
  • Health: Since the humidity level of a whole house humidifier is kept constant, it helps you breathe healthy air, no matter which room you are in. Dry air can increase the chances of sinus problems and cause nose bleeds and respiratory problems. However, when the air is humidified, it reduces dry skin and throat, chapped lips and snoring.
  • Comfort: Humid air is warmer than dry air, set at the same temperature. By adding a furnace to your whole house humidifier, the heated air allows you to set your thermostat a few degrees lower so that you enjoy the same warmth and comfort all over your house. Besides, having a lowered thermostat lets you save money on your heating bill.
  • Operating Costs: A whole-house humidifier is made part of your household water system, so you don’t have to buy any special water. This increases your water bill marginally.

Types of whole house humidifiers

All whole house humidifiers are installed directly into the home’s central heating and air conditioning systems. Together, they normalize the humidity all over your home and automatically add moisturize the system when the furnace or air conditioner comes on. The point of difference is in the way they bring in moisture to the system. There are three common types of whole house humidifiers:

Drum Systems: These humidifiers have a fabric or foam belt that spins on a drum kept on a water reservoir. The belt absorbs moisture from the reservoir, and when the air conditioner or furnace blows air over the drum, the moisture evaporates into the air and wafts all over your home. Of the three types of whole house humidifiers, drum systems are the cheapest, but they need to be cleaned often or mould grows in the water reservoir.

Flow-Through Systems: operate by dripping water through a foam or aluminium pad. Your furnace or A/C blows air through the pad, picking up moisture and delivering it to the rest of your home. Flow through systems don’t have the problems with mold that drum systems have, though you will need to clean or replace the pad periodically since it will eventually accumulate dust and dirt and clog up.

Spray Mist Systems: These devices let out a very fine spray into the ductwork of your home when your furnace or air conditioner begins to work. Though they don’t need the ongoing maintenance that drum or flow-through systems do, yet they can develop mineral deposits if your mineral water supply gives you hard water.
