House plants that clean the air

House plants can improve your home, both visually and atmospherically. Here are five attractive plants which remove toxins, improve air quality and, as a bonus, are well suited to Singapore’s humidity.

Living in closed work and home environments, reliant on air-conditioning and without sufficient natural ventilation, increases our exposure to chemical vapours and toxins. Carpeting, plastics, paint, synthetic building materials and cleaning products can emit harmful elements such as trichloroethylene, benzene and formaldehyde.

Studies by NASA on air quality inside spacecraft have shown that some house plants can filter out these pollutants through the natural process of photosynthesis. Even better news is that some tropical plants are among the most efficient at removing harmful pollutants from the air.

The definitive book on plants and air quality is B. C. Wolverton’s How to Grow Fresh Air: 50 Houseplants That Purify Your Home or Office. It’s easily available online and in the local library.  Here are some house plants for your Singapore home.

Five house plants to get you started

3. Rubber Plant

Outdoors, the rubber plant can grow into a large tree, and even indoors can reach over two metres. The large, glossy leaves make a striking feature in large rooms. They do best in semi-shade, even in dim light, with moderate water. Renowned for removing formaldehyde.

4. Peace Lily

Lilies are a favourite for their shiny foliage and statement flowers. They enjoy moderate watering in a semi-shaded position. Excellent for removing all pollutants including benzene, alcohols and trichloroethylene.

5. Boston Fern

Ferns are ubiquitous in Asia and there’s a variety to suit almost every home. The Boston fern is rated for its lush foliage and ability to remove toxins from the air. Ferns are needy and require regular fertiliser, semi-shade, moderate watering and regular misting.

6. Snake Plant?

The snake plant is the obvious choice for anyone who travels regularly or does not have a green thumb. It tolerates neglect, requires little watering and its tough leaves are virtually indestructible. Look around hotels and office lobbies and you’ll see it everywhere. It’s also useful for removing chemical vapours from the air.
