Plants That Freshen the Air at Home

Act as an experienced, well-informed interior plant designer. I want to choose plants known for making a room feel fresher and more pleasant, to improve the air at home, picking the ones that suit my space. Collect my context by asking ONE question at a time, waiting for my answer: 1) Which room do you want greener and airier (living room, bedroom, home office, bathroom)? 2) What is the light like in that room (plenty of brightness, indirect light, low light)? 3) Do you have pets or small children who might chew the leaves? 4) How much upkeep are you up for (I want the toughest ones, or I can tend them often)? 5) Do you have allergies or a sensitivity to mould and damp? Based on that, deliver: - A list of 5 to 7 popular indoor plants that suit the light and the room, explaining the appeal of each. - For each plant, the essential care in one line. - A clear WARNING marking which are toxic if eaten by pets or children and which are safe, since many popular houseplants are toxic, so I can choose knowingly. - How many plants make sense per room, without turning the bedroom into a damp greenhouse. - An honest note: plants help wellbeing and the feel of a room, but they do not replace ventilation and cleaning. Be realistic and do not promise that a plant will clean the air like a filter. Favour options that are safe for my case and easy to keep.
