Heartleaf Philodendron (Philodendron hederaceum) is noted by NASA among the best types of houseplants for removing formaldahyde, especially higher concentrations.
It is capable to absorb between 80 and 90% of the formaldehyde present in water-based paint, roofing felt or insulation material, glues in fitted carpets or even laminated wood floors!
Also, this Philodendron can be used successfully for indoor vertical gardens.
Philodendron hederaceum is an evergreen climber growing to 3–6m (10–20 feet), with heart-shaped glossy leaves 10cm (4 inch) long and 8cm (3 inch) wide with 5-8cm (2-3 inch) long leaf-stalk. The leaves have acutely pointed tips. The leaves look slightly brownish and almost transparent when they are new, but they quickly become deep green as they grow to maturity. Occasionally spathes of white flowers appear in mature plants.

Known for their ability to thrive in low-light conditions typical of many homes and offices, Philodendron hederaceum plants are often grown for their lush foliage. It can be grown as a climbing or training specimen depending on whether its long stems are trained up supports or are allowed to trail over the rims of the pots or hanging baskets.
Philodendron hederaceum as a climbing species is usually tried to a stake inserted into the potting mixture for support. For best results, dress the stake in sphagnum moss until form a 5-8cm (2-3 inch) thickness over the full length of the stake above the potting mixture level. Alternatively, nail a piece of rough-textured cork-bark to the stake. The sphagnum moss or cork-bark being used must then be sprayed with water at least once a day. Doing this it will stimulate the aerial roots of the Philodendron hederaceum to get a firm hold on this support. Be sure that the support is tall enough to accommodate the eventual total growth of the plant.
