Water Air Purifier: How It Works?

You don’t have to be a mechanical genius or very handy to keep them in good repair.


eowners everywhere enjoy using these because of how easy they are to own and operate.

What Does A Water Air Purifier Do

It’s basically three easy steps that water air purifiers work.

First, the air in your home is pulled into the machine, using an intake vent.


the air is put into the water basin and swirled around inside the device.

We call it the “rainstorm”. It traps the majority of particles.

But mostly dust particles. And doesn’t remove as many pollutants as true HEPA would.


, the air is released back into the room.

Water-based air purifiers work by drawing in dirty air to the water basin of the unit.

By doing this, all solid particulates are trapped within the water.

Once the

air has been filtered using the water in the device, it will be further purified. It swirls around inside the device.

Imagine if you will a very intense “rainstorm”. The particles are put through this “storm,” or pressurized water.

This weighs down and further traps particulates from escaping.

And that’s not al

l! The third line of defense is usually an electrostatic filter or another filter (such as a carbon one). It traps any remaining particles.

Do Air Purifiers Need Water?

The good news is that basic air purifiers do not generally use water.

So, if you’d prefer

to use a non-water-based air purifier you may do so. You will never have to worry about using water to get the air clean.

These types of air purifiers use HEPA (high-efficiency particulate air) filters to clean the air.  

HEPA filters are exceptional at absorbing small particles within the air.

They work by pushing

air through a very fine mesh.

This entraps particles like pet dander, smoke from tobacco, pollen, and dust mites, among others. HEPA makes use of activated carbon filtration.  

This gets rid of gases and odors from the air. It gives it a fresh and clean smell.

Start by finding out

how much area the air purifier is capable of cleaning.

You will want to purchase one that is large enough for the room in question.

The act of using it is very easy. You simply follow the package directions to add the water and plug it in.

But here are things y

ou can do in order to maximize its effectiveness.

Keep doors and windows shut.

You can’t purify the great outdoors, so keep doors and windows shut while the device is running. Make sure you seal up any drafts as well.

If using a filter, clea

n it or change it regularly- If you purchase one of these devices that uses HEPA or other filters, you replace them.

Follow as per the manufacturer’s recommendation. 

Clean washable filters each week for best results. Most of the time, you will need to replace filters once per year.

But this is dependent on

how polluted the air is within your home.

Don’t shut it off- Do you live in a home where people smoke, or pets are always around?

Are you trying to clear the air for people with asthma or allergies?

Keep in mind that, HEPA air

purifiers have been scientifically proven to fight against allergies.

Water-based air purifiers do not have any scientific evidence that they actually do anything for your health.

Although, water-based air purifiers devices are engineered to be energy efficient. Thus, you won’t notice a big spike in the electric bill.

Position It Correctly- Are yo

u placing the device in a larger room?

You should make sure the stream of clean air from your purifier is directed toward where people are.

If the room the purifier will be in is small, you can set it anywhere. This is because the air will circulate around.

Location, Location, Location-

Make sure your water-based air purifier has some breathing room.

It needs a few feet of space around the sides and top of the device. This is so air can circulate with zero obstruction.

How Do I Add Scents to My Water-Based Air Revitalizer?

Adding scents to your air revitalizer is easy to do.

You will want to do this by p

urchasing essential oils in smells that you like.

Or choose ones that will benefit your family. Some air revitalizers will even come with vials of essential oil you can use.

You will first read the manufacturer’s directions carefully.

Then you will safely add the oi

ls to the specific compartment on the device.

Other individuals using water-based air purifiers simply add a few drops to the water chamber. Then enjoy the scents that way.

If you’re stuck on which scents are best, here are some we love.

Adjust the recipe to suit you

r room size and individual taste:

  • 5 drops of peppermint and 2 drops of rosemary to refresh a room
  • 5 drops lavender and 2 drops lemon oil for a beautifully scented and calming room
  • 2 drops of lemon, lavender, and peppermint each, plus 1 drop of tea tree oil. This particular blend may help with controlling pathogens and bacteria.

How to Clean A Water-Based Air Purifier?

First, think safety. Turn off and unplug your machine.

Put on gloves to keep your hands safe.

Remove the bowl portion and place

it in a bucket of hot water, or your sink.

Then add 1c white vinegar. Allow it to soak for a half-hour.

Now remove it and wipe it down.

And just like that, you should ha

ve a nice, clean good-as-new air purifier.
