Here are the Top 5 Air Purifying, easy to care, indoor plants that are widely available.
 1. SNAKE PLANT (Sansevieria):
Also cleverly knows as ‘Mother in law’s tongue’, is must-have for every house, garden, office or even a bathroom. A plant that’s so resilient, even a person with zero gardening abilities will be able to make it work. The snake has many different varieties, all easy to care for.

It is known to remove Formaldehyde from the air. It will do well in any light conditions from extreme heat to very low light. It likes well-draining soil and being root/ pot bound. The long, upright pointy leaves, make it a great interior décor statement. 

The only thing to remember here is that this plant can get root rot if watered too much. So just relax, cut back on the watering and only give it water when the soil completely bone dry. 

2. PEACE LILY (Spathiphyllum):
 A cool green plant that has beautiful foliage and lovely blooms. These plants are known to filter Formaldahydes and benzene. 

They like to have moist soil and humidity. They like medium light or shade. They can tolerate low light, but may not flower in such conditions.

A pretty easy plant to take care of. Try to keep away from direct harsh sunlight and careful of overwatering and over fertilising.

 3. SPIDER PLANT(Chlorophytum comosum): 
These funky plants have the ability to filter formaldehyde from the air and look very cool while doing so.

They like well-draining soil and bright light. Wait for the soil to dry out between waterings as they don’t like being soggy. They are susceptible to dry tips, in that case, keep the soil slightly moist but not drenched.

If we get all these conditions right, these plants start shooting out little baby spider plants that are just too cute. You can then snip these baby plants and make smaller plants. I don’t know what could be better!

4. MONEY PLANT (Epipremnum aureum):
Also known as Pothos, this is a fast-growing, easy, beautiful vining plant. They like bright indirect light. They can do just fine in low light as well. They can filter out benzene. They are several different varieties with variegated leaves 

They like well-draining soil and likes the soil get dry between watering

They make a lovely plant for home décor. You can steak them up on a moss pole or a ladder or anything it can climb up on or leave it in a hanging basket for a completely different look.
