they take CO2 in and release O2, and the process is called photosynthesis
They breath pollution and carbon dioxside.

Nitrogen fixation is the process by which bacteria remove nitrogen from the air and make it available to plants.
Transpiration
I'm guessing that you saw a plant tag on a spider plant advertising the plant's ability to "purify the air"? That's mostly just a marketing scheme used to make you think that spider plants have some extra powers that other plants don't have, but it's not true. I've seen that same kind of statement on tags for all kinds of plants. All plants purify the air by removing volatile organic compounds, which the plant uses in its regular metabolism, and the removal of VOCs means cleaner air. Having houseplants can have a measurable effect on the concentration of VOCs, so to say that a plant purifies the air is definitely true. And it's reasonable to think that different plants use more VOCs than others, but I can't find any evidence to say that spider plants are actually better at purifying air than any other houseplant. NASA found that the spider plant is especially good at removing formaldehyde, and can also remove xylene and toluene, though it is not in the "top 10 list". To be effective "air cleaners" it is necessary to use 1 potted plant per 100 square feet of home or office space.
All plants.
Air plants do not significantly purify the air in a room. They primarily absorb moisture and nutrients from the air rather than filtering out pollutants.
Any plants that are in the house will help freshen the air.
They breath pollution and carbon dioxside.
The process to purify ore and produce steel is known as the Bessemer process, which was invented by Sir Henry Bessemer in 1856. This process involves blowing air through molten iron to remove impurities and increase the carbon content, resulting in the production of steel.

yes
Candles do not purify the air in a room. While they can add a pleasant scent, they do not have the ability to remove pollutants or improve air quality.
This eucalyptus ointment will help to purify the air.
No, plants lose water to the air through a process known as transpiration.
Plants purify air composition by absorbing CO2 and releasing Oxygen. By way of transpiration plants add humidity in the air and broad leafed trees also help in reducing suspended particulate matter from the air. A good number of aquatic plants absorb heavy metals from water. Thus plants help us fighting pollution in many ways.
Yes, beeswax candles can help purify the air when burned because they release negative ions that can neutralize pollutants and allergens in the air.
