6 DIY Humidifiers

For asthma and allergy sufferers, a humidifier is a lifesaver. The problem is that a good one can cost hundreds of dollars, and they all tend to break down from constant use. Luckily, a number of DIY alternatives can be just as effective at a fraction of the price. With a little time and effort, you can put together anything from a simple mister to an ultrasonic model or even a tornado humidifier. So, without further ado, here are the six most impressive and user-friendly DIY humidifier guides ever made.

1. DIY Tornado Humidifier

This mesmerizing DIY humidifier proves that, with the right tools and a little elbow grease, you can outdo any mass-produced appliance. Sure, building an exposed tornado humidifier is a long, relatively expensive venture. But, let's be honest, it is worth every penny. Here's the tutorial:

Vornado Evap40 4-Gallon Evaporative Humidifier
  • Humidifies up to 1,000 sq. ft. through the use of signature vortex circulation. Hertz - 60 HZ. The high speed RPM is...
  • Adjustable humidistat for automatic humidity control and 3 speed settings (low, medium, high)
  • 4 gallon capacity and up to 4 gallon output every 24 hours for long, uninterrupted operation

Before you get started, make sure you have all of these materials:

  • Standard trash can
  • Inline duct fan. You can use a 4" or a 6" fan. The smaller one is less expensive but more noisy.
  • PVC Board. It must be larger than the diameter of your trash can, which means you need at least a 25" x 25" piece.
  • Five 1" PVC couplings
  • 3" to 4" PVC adapter
  • Five 1", 5-foot-long PVC pipes. Aluminium piping works just as well but it's a bit more expensive.
  • Hot glue gun
  • Three Ultrasonic Foggers
  • Spray paint (optional)

2. DIY Ultrasonic Humidifier

If you want to get the most bang for your buck, this $10 ultrasonic humidifier is just what you're looking for. Even if you have no DIY skills, the whole project won't take longer than 30 minutes to complete. You may need two of these to humidify large areas, so consider stocking up on these materials for this homemade humidifier:

  • Ultrasonic Mister. The smallest available unit will work just fine, but make sure it includes power supply wiring.
  • Computer fan. Ideally, you need a low-voltage fan with a diameter of three inches or less. But it's possible to use a bigger size so, if you have one lying around, go for it.
  • DC connector. You need the 'female' adapter.
  • Tape. For best results, use the tough and waterproof Gorilla Tape.
  • Plastic bottle. You'll need to refill the humidifier every two days or so, but it can last twice as long with a taller bottle.

3. DIY Evaporative Sponge Humidifier

This DIY humidifier is the most low-maintenance appliance you will ever own. The assembly process for this evaporative humidifier is quite simple and straightforward, though it may take a while to finish. Plus, most of the required materials are common household items. Here's the full list to make your own humidifier:

  • Digital Controls with Auto Humidistat
  • 3-Speed Motor with Quiet Nighttime Setting
  • Automatically Shuts Off When Desired Humidity Level is Reached or When Unit is Empty
  • Automatic pet water bowl. Any similar bowl can be used as long as it has a water reservoir that gradually refills the container.
  • Small computer fan. To minimize noise, look for a brush-less fan or one that comes with a silencer.
  • Four thick sponges. Soft foam dish sponges won't work.
  • Tupperware container. You need one roughly the same size as the open part of your pet water bowl.
  • Four bolts with matching nuts.

4. DIY Humidifier on a Budget

It may not be the most creative DIY guide, but it's surprisingly effective for a low-budget humidifier. As a matter of fact, in most households, it's a totally free project. Putting it together couldn't be any easier, and you probably already have all the needed materials.

  • Fan. Literally, any kind of fan will work. Plus, it won't get damaged in the process.
  • Disposable aluminium baking pan
  • Evaporation Foam Cooling Pads. These can be replaced with dish sponges, though you'll need much more than two.
