When most people think of air purifiers, they think of the type with filters in them, but air purifiers can use different technology to attract and eliminate pollutants, including ozone, ionization, and even water.

In fact, water-based air purifiers are growing in popularity because they not only clean the air but can also be used as a diffuser and humidifier at the same time. Most of the time, a good air purifier with water puts moisture in the air and some even come with scented oils that you can put in the water to make everything smell great.

How Does a Water-Based Air Purifier Work?

Like filter-based air purifiers, an air purifier that works with water has a fan that draws in the contaminants, then leaves them into the water. Water molecules are in fact a bit sticky, which means the pollutants automatically “stick” to the water. Benefits of air purifiers with water are:

  • User-friendly
  • Quiet
  • Easy to read displays
  • Low running cost

These types of purifiers are very user-friendly and come with easy-to-read displays and low decibel levels. They work much the same way as air purifiers with filters do, but they contain the contaminants in the water, which is their “filter.”

If you’re wondering, do water-based air purifiers work as well as filter-based air purifiers, the answer is, “no,” they usually do not. But before you scrap your plans to buy one of these units and go with a filter-based purifier instead, keep in mind that water-based purifiers still get rid of contaminants, and they are usually much cheaper.

Things You Should Know About Water-Based Air Purifiers

The main thing to keep in mind when researching water-based air purifiers is that although they are great at eliminating large airborne particles in your home or office, they don’t always do well with very small contaminants. For this, a true HEPA filter works best, which means you’ll need a standard air purifier that works using one of these filters instead. Still, if you’re looking for an air purifier that also acts as a scent diffuser and humidifier and you’re on a budget, these purifiers are just what you need.

In addition, these air purifiers also tend to be quiet, low-maintenance, portable, and compact, and save you from having to change filters from now on. This alone makes them a favorite type of air purifier for many people.

Final Thoughts

Water-based air purifiers are great for rooms of all sizes and are affordable. They are easy to operate and can even be used with fragrance oils, which come in many different scents. You can even use your own scented oils if that’s what you prefer to do.

Although many manufacturers recommend using distilled water in these purifiers, others work well with simple tap water. It is well worth it to consider buying a water-based air purifier for your home or office.
