Why Do You Need an Air Purifier Without Water?

The EPA and other air-quality experts have claimed that the average home’s indoor air is up to five times unhealthier than the air we breathe when we’re outside. A good quality air purifier is one of the best – and one of the least expensive – ways to take care of the problem. Waterless air purifiers use a fan to draw in unhealthy particles from the air, where they are kept in a filter until the filter is replaced.

The benefits of air purifiers without water are:

  • excellent for reducing mould and fungal problems
  • better at filtering air
  • better at removing odors
  • filter larger rooms
  • less cleaning needed
  • no spillage problems

The most efficient air purifier uses a true HEPA filter, which captures 99.97% of all pollutants as tiny as 0.3 microns, which means hardly anything gets past it.

Some of the pollutants captured by a good air purifier include:

  • pollen
  • dust
  • pet dander
  • cigarette smoke
  • bacteria
  • viruses
  • wildfire smoke

By letting the purifier run 24 hours a day, seven days a week, you can keep the air fresh and clean all day, every day. An air purifier eliminates contaminants and certain odors, which means the air not only smells better, but it is much healthier as well. This is especially important if you have anyone in your home with a weakened immune system, allergy or sinus problems, asthma, or any other type of upper-respiratory problems.

When you go shopping for your next air purifier, keep in mind that there are several types, including those that use ozone and those that use the ionization process to get rid of nasty pollutants. Most, however, still have some type of filter since it is the filter that traps and therefore eliminates the pollutants in the air.

Final Thoughts

For people with asthma or allergy problems, a good quality air purifier can be a true miracle worker because it attracts even very small particulates and pollutants in the air and gets rid of them so they’re no longer there. If you love breathing fresh clean air 24/7, one of these air purifiers is bound to be the right one for you, and the fact that they work without water makes them easy to install anywhere.
