Keep A Snake Plant In Your Bedroom To Improve The Air Quality While You Sleep

The Snake Plant, or Mother-in-Law's Tongue, is one of the most recommended plants for improving air quality. The optimal place to keep this relatively inexpensive and low-maintenance plant is the bedroom, because it converts CO2 into oxygen at night.In its roundup of the best cheap plants for improving indoor air quality, Wisebread notes that Mother-in-Law's Tongue is recommended by a NASA study (which lists at least a dozen air-improving plants) and researcher Kamal Meattle, who has shown us that just three common houseplants can improve indoor air.Meattle says Mother-in-Law's Tongue is known as "the bedroom plant." While most plants take away oxygen at night, this one gives off oxygen at night. The plant also filters formaldehyde, trichloroethylene, xylene, toluene, and benzene from the air. Meattle recommends 6-8 waist-high plants per person for optimal output from this oxygen factory.Dry indoor air is blamed for a host of respiratory problems, particularly in the winter, and plants emit water vapor duringtranspiration. 
Helping to maintain humidity levels: Dry indoor air is blamed for a host of respiratory problems, particularly in the winter, and plants emit water vapor duringtranspiration. 
Producing negative ions: Plant leaves produce negative ions, similar to many air purifying machines. Negative ions attach themselves to (and effectively remove) particles such as dust, mold spores, bacteria, and allergens. The presence of negative ions is credited for increasing psychological health, productivity, and overall well-being.
