Recently, I moved into my new apartment, in one of the most polluted cities on Earth, Paris. Therefore I decided I needed houseplants to clean the air. What an idea! Is it bullshit? Does it actually work? Who cares?! As long as it makes my apartment look cool!

Consequently, I started googling about evergreen houseplants that clean the air. I ended up buying the following plants:

Some time later I'll post here how to take care of these houseplants.

Aglaonema

Temperature

Between 15°C and 25°C. Cannot tolerate below 13.

Light

300 lux, half shadow, must get sun light a few hours per day (no direct sunlignt though).

Watering

Soil should be kept moist at all times. Don't allow it to dry otherwise it can cause leaves to drop. In summer, water twice a week. In winter, once. Don't leave standing water in the saucer.

Repotting

Repotting is from March to May, every 2 to 3 years. For an old Aglaonema, just replace the upper layer of the soil, do not repot.

Complementary information

Leaves and fruits are toxic for humans and pets.

Dracaena Marginata

Temperature

Between 15°C and 22°C. Avoid below 15 (won't grow otherwise). Below 10 could damage it. Best between 20 and 22.

Light

500 lux, quite a log of light. Avoid too much direct sun light. It does not like absence of light.

Watering

Soil must remain hardly moist. Once a week in Summer, twice a month in Winter. Mist the leaves twice a week also, if possible.

Repotting

Repotting is from March to May, every 2 to 3 years. Every other year, replace the upper layer of the soil, do not repot.

Spathiphyllum

Temperature

Between 15°C and 25°C. Below 10 could damage it seriously. Best between 20 and 22.

Light

A significant amount (300 lux at least) but no direct sun though. Dim light is OK.

Watering

Once a week, a lot. Don't leave standing water! Reduce the amount of water in winter.

Repotting

In March, every two to three years. When not repotting, replace the upper layer of the soil.

A lot! 600 lux at least. No direct sun light.
