However, evidence has been increasing for some time that all of these products contain industrial chemicals which can, among other things, damage lungs, aggravate asthma and cause tumours.
Sprays, plug-ins and gels
Chemical sprays, plug-ins and gels for home perfuming are hugely popular but they can include an array of hazardous substances which may cause lung damage and tumours, interfere with our hormones and aggravate conditions such as asthma.
Many air fresheners employ carcinogens, volatile organic compounds (which are characterised by their low boiling point which mean they form a gas at room temperature) which are known to increase the risk of asthma in children and known toxins such as phthalate esters in their formulas.
The evidence of harm is mounting:
But manufacturers refute such concerns
Manufacturers of air fresheners, however, maintain that their products are safe. In June 2015, SC Johnson, which makes Glade air fresheners, published specific information on most of the ingredients in its products for the first time.
Company chairman Fisk Johnson says: 'We take great care in making ingredient choices to offer products that are both safe and effective.'
However, not all of the ingredients used in the actual perfumes are fully listed and could well be made up of many different chemicals.
However, SC Johnson maintains that all its fragrance ingredients, even those not listed, are safe: 'While they are not disclosed, the remaining ingredients also must meet our strict standards.'
Incense are no better
Millions of us burn them every day to send spiritually inspiring wafts of spiciness around our homes. Research shows that ingredients such as frankincense can cause chemical changes in our brains, lifting our moods.
However, incense's mystic allure has been clouded by new findings warning that its fumes may be more dangerous than cigarette smoke, causing cancerous mutations in our DNA.
Burning incense releases tiny chemical particles which can become trapped in our lungs, causing potentially dangerous inflammatory reactions.
The research also found that incense particles from commonly used ingredients agarwood and sandalwood are more toxic to our cells' DNA than tobacco smoke.
Nor are scented candles
Scented candles bring another dimension, adding that subtle hint of aromatic bliss. Scientists remain unmoved however, voicing extreme concerns about the pollution that they are bringing to our lives.
In March 2015, a team of experts tested six scented candles, with such aromas as clean cotton, strawberry and kiwi fruit.
Behind their labels, however, lay a host of potentially dangerous industrial chemicals, including formaldehyde at levels which, with long-term exposure, are known to raise the risk of respiratory problems and cancer.
The candles also gave off significant levels of VOCs. Furthermore, the study warned that you don't even need to light such candles because simple evaporation will enable them to pollute your home.
Most scented candles are made with paraffin, which brings other problems. The oil by-product gives off ultra-fine soot particles containing acetone, benzene and toluene, usually seen in diesel emissions, and known carcinogens.
