What Kind Of Candles Purify The Air?

Beeswax candles:

beeswax candles have been used for centuries to purify the air.

By releasing negative ions when they burn. These ions attach themselves to the positively charged dust, mold, and other pollutants in the air. Causing them to fall on the ground instead of being airborne and breathing them in.

Other types of candles will not clean the air as well as beeswax ones.

This is because paraffin wax burns with a sooty flame which releases black smoke into the air that contains toxins. These toxins can cause respiratory problems and other health issues.

Do Scented Candles Cause Air Pollution?

According to the EPA, burning candles that contain lead core wicks can result in indoor air concentrations of lead above EPA-recommended thresholds.

Also, another study claimed that the worst-case scenario concentrations of candle emission can contain acrolein, formaldehyde, and acetaldehyde which exceeds the EPA-recommended thresholds

While scented candles can cause allergic reactions and respiratory problems.

This is because the scent particles can be breathed in and cause health issues.

For this reason, if you have any breathing issues or you are allergic to certain scents, then avoid using scented candles.

Do Burning Candles Help With Dust?

Yes, burning beeswax candles helps to get rid of dust.

The negative ions they release attach to the positively charged dust particles and cause them to fall on the ground. This helps to get rid of the dust in the air.

However, the dust particles that fall onto the ground will not get rid of dust completely. This is because candles do not have a HEPA filter.

If you want to get rid of dust completely out of the air it is much better to use an air purifier to do this task.

Do Candles Take Oxygen Out Of The Air?

Yes, burning candles do take oxygen out of the air.

However, the amount they take is negligible and not enough to cause any health issues.

Also, if you are in a large room, the oxygen taken by the candle is replaced by the oxygen that comes in through open windows and doors.

So there is no cause for alarm if you are burning a candle in your home.

Candles won’t deplete the oxygen in the air unless they are in an enclosed space with no windows and doors to get fresh air and there are so many of them burning at the same time that it creates a deficiency.

What Gas Does A Candle Give Off?

Burning candles give off two gases: carbon dioxide and water vapor.

The oxygen from the air reacts with the burning wax to create these gases. Other products of the chemical reaction, of course, include heat and light.

Can Candles Get Rid Of Bad Smells?

Yes, candles can help get rid of bad odors in two ways. The first is by simply covering up the smell with a scent of your choice. There are so many scented candles that will help mask bad odors.

While this doesn’t really get rid of the odor, it makes the room smell better and more pleasant.

The second way is by burning beeswax candles which release negative ions. These attach to the positively charged particles in the air that are responsible for bad odors.

The Downsides To Burning Candles In Your Home

While there are no major drawbacks of using natural wax candles at home, those made from paraffin wax or other types of candles may pollute indoor air and can sometimes be harmful.

When they burn, they release toluene, benzene, acrolein, formaldehyde, and other harmful chemicals into the air.

They also release soot, which can be harmful to your lungs over time.

So, if you are using candles made from other types of wax, make sure that you burn them in a well-ventilated area and do not let them burn for too long.

How Can I Naturally Purify The Air In My Home?

There are many ways to naturally purify the air in your home. They include the following, among others:

  • Using indoor plants

Plants are a great way to naturally purify the air in your home. They absorb harmful toxins and gases and release oxygen into the air. Some of the best plants for this purpose include peace lilies, bamboo palm, English ivy, spider plant, and mother-in-law’s tongue.

  • Opening windows and doors regularly

This will ensure that fresh air and sunlight can get into your home. It also helps to ventilate the house by removing stale air.
