Summarize:

Fill your home with indoor plants to purify the air and increase oxygen in your space. If you have limited room, put plants in the rooms you use the most, like your bedroom and kitchen. If you have pets, research online before purchasing plants to make sure they're non-toxic. All plants are good at boosting the oxygen in your home, but the following are very efficient: Aloe English ivy Rubber tree Peace lily Philodendron Snake plant Spider plant Red-edged dracaena Golden pothos Though not scientifically proven, some believe that lamps made from pink Himalayan salt may help to purify the air. They emit a nice pink glow as well. This may not generate enough negative ions to change your environment, but it might help remove some of the toxins in the air around you. Candles made of beeswax don't smoke when they're lit, and they don't release chemicals as they burn. Similar to salt lamps, these candles don't release enough ions to purify the air completely. However, beeswax candles may be a healthier substitute for more common candles made of paraffin, which usually emit pollutants. You can purchase beeswax candles at your local health food store or online. Never let candles burn unattended.
Put plants in your home. Get a salt lamp. Burn beeswax candles.
