What Is A Water Based Air Purifier And How Does It Work?

Water air purifiers are different from ordnary air purifiers because they use water to clean the air. Unlike the traditional air purifiers, the air water based air purifiers do not use HEPA filter to Purify the air. Instead, they use water. On top of that, these air purifiers can also be used to humidify your environment. 

The air in the room is drawn into the purifier, then particles and other pollutants are trapped into the water. Then the washed air is released back into the room from the other side of the purifier. 

Water air purifiers help reduced the number of pollutants in the air including 

  • Dust mites 
  • Mould,  
  • pollen 
  •  cooking smells 

They are also great for people with alleges or those who suffer from Asthma.

These air purifiers do remove pollutants and bacteria from the air to some extent but I should make it clear that they are not as accurate as the Hepa filters that are used by the ordinary purifiers, which remove more than 99% of impurities from the air.

However, water air purifier come in as a natural way to clean the air and at the same time humidifying your surrounding air without anyadditional cost.

How To Clean A Water Based Air Purifier

  1. Switch off your device and unplug it from the power source. This is a first and safety step to protect yourself from any kind of electric shock. 
  1. Remove the top of the purifier. You can do this by unscrewing it, but it depends on the device that you are using. 
  1. Remove the fan and clean it. The fan draws in air into the purifier and pushes it out into the room on the other side. So dirty air passes through them and it can accumulate over time. Because of that, we recommend cleaning the fan to ensure that the air that you get is clean. 
  1. Clean the water basin:  It is important that you clean the basin with soapy water because that is where mold would likely build up overtime if no regular cleaning is done. 
  1. Clean your device’s stem:  This is the part that stirs the water so that the pollutants are trapped in there. Gently and carefully clean it. Overtime, residue can accumulate. 

Once you are done with the cleaning, leave your device to dry.  You can either leave it under the sun, or you can simply let the air dry it.  After everything is dry, you can now put them back together, fill the basin with water and plug in your unit. 

Frequently Asked Questions (FAQs)

How often should you change the water in an air purifier?

About a day or so. But generally, how often you need to change the water depends on the model of the water air purifier you are using.

Many manufacturers recommend changing water and cleaning the basin once per day. But for other models, like the Venta LW25 Comfort Plus Airwasher, you will only need to change the water after 10 to 14 days (about 2 weeks) depending on the quality of the air. 

How long does it take for an air purifier to clean a room?

An air purifier would take anywhere from 30 minutes to 3 hours to clean your room. But you should be able to notice the difference in the quality of the air within 30 minutes of running your purifier. 

Generally, there are factors to consider before you can estimate how long it will take your purifier to clean your room such as coverage of the air purifier, the size of the room, the fan speed etc, 

Is it ok to leave air purifier on all night?

You can leave your air purifier on all the night, all days of the week. Infact, air purifiers are designed to be running all the time even when you are not home.

Dust and other unwanted particles constantly enter your room even when the doors or windows are closed. They sneak in through gaps between doors or windows or cracks even if we don’t see them. 

Can you use an air purifier with windows open?

You can use your air purifier with open windows, but it won’t be as effective as it would with windows closed. Just by keeping windows closed, the particulate pollution in the air will be about half the level of outdoor air  

If you want to use your purifier with windows open, the best way you can do it is, use a purifier that with coverage rating larger than your room size. 

Are air purifiers a waste of money?

No. Air purifiers are not a waste of money. They are effective at cleaning the surrounding air and they also help people with alleges or asthma issues. They come with many health benefits such as reducing the chances of airborne diseases including flue and cold.  So air purifiers are worth it.
