Hey, welcome to the forum! Snake plants (aka mother-in-law’s tongue) are spot-on for what you’re after-they use CAM photosynthesis to pump out oxygen at night and scrub some toxins like benzene. Super low-maintenance, drought-tolerant, and safe for bedrooms (non-toxic to humans, but keep away from pets). Peace lilies are great purifiers too, but they don’t release O2 at night like snakes do. If you want another easy one, try the spider plant-it’s forgiving for newbies and helps with formaldehyde. Start with good indirect light and well-draining soil!
