When you learn the differences between Paraffin and Beeswax candles,
you will be sold on the ones made by bees !

“Regular candles,” like the bag of tea lights you can buy for just $5 are made from paraffin. As the name implies, paraffin candles are made from paraffin wax, a by-product of petroleum refining. Hence they are a highly toxic and environmentally unfriendly product that literally poisons the air you breathe.
Conversely, beeswax candles improve the quality of the air in a room when burned.
Paraffin wax starts as the sludge at the bottom of the barrel of crude oil. Even asphalt is extracted before paraffin in the refining process! The black sludge, already filled with numerous toxins, undergoes bleaching and treatment by the carcinogens benzene and/or toluene.
The chemical mix increases with the addition of various toxic concoctions of colors and fragrances to make this waste product marketable and appealing. The final result is an innocent looking candle which releases seven documented toxins – two of which are carcinogenic – as it burns.
And toxins aren’t the only problem with burning paraffin candles. Over time, repeatedly burning paraffin candles leaves black soot stains on walls, ceilings, furniture, and drapery. The microscopic soot particles at fault for the cosmetic damage also cause serious health problems. These tiny particles are easily inhaled and get trapped in the deepest part of the lungs, which may cause respiratory irritation.

How beeswax candles clear the air
Beeswax releases negative ions as it burns. Airborne pollen, dust, mites, dirt, pollutants,  all carry a positive charge, and that is how they can be suspended in the air. The negative ions released from burning beeswax negate the positive charge of air contaminants, and the neutralized ions are sucked back into the burning candle or fall to the ground. Similarly, many air purifiers and water filters utilize negative ion technology to remove toxins.
Because beeswax candles clean the air and reduce indoor pollutants, they can effectively reduce asthma, allergies, and hay fever symptoms. There are many anecdotal reports of asthma and allergy symptom relief as a result of burning beeswax candles.  For many with chemical and fragrance sensitivities, these are the only candles they can burn since the beeswax doesn’t release those irritating toxins

Watch out for sneaky labeling on beeswax candles.
In the U.S., the term “pure” on a label means only 51% of an ingredient (and that goes for food, too). Often, companies sell “pure” beeswax candles which contain a combination of 51% beeswax and 49% toxic paraffin. Look for the key phrase “100% Pure Beeswax” on candles.
