How to Maximize Air Purification
5 Tips for Cleaner Air with Houseplants
- 1. Place 1–2 plants per 100 square feet for optimal effect.
- 2. Keep leaves dust-free by wiping gently with a damp cloth — dust blocks pores.
- 3. Provide adequate light; most air-purifiers thrive in bright, indirect light.
- 4. Use well-draining pots to prevent root rot — overwatering is the #1 killer.
- 5. Rotate plants occasionally for even growth and maximum air exposure.
