Air Purifiers

I have neighbors that excessively use pesticides on their lawn. Being concerned that some of these poisons might be permeated into my home, I purchased the 5000 series Vocarb from AllerAir to set in my bedroom. It has..

Filtration System: Vocarb Carbon, Micro HEPA, Prodense Pre-filter
Carbon Filter: 18 lbs Vocarb, 2.5" Depth

The page for it can be found here.

Will this filter suck all of the pesticides out of the indoor air, or is even it not enough? I also have a Spider Plant, Golden Pothos plant, and Bamboo plant in my room. With the plants working in conjuction with the air filter, should there be no measurable level of pesticide residue in my room that might be inhaled?

My friend just moved to an apartment and is concerned about off gassing and indoor air pollution; we are in a friendly debate as to what strategy [or combination approaches] is best to address her concerns. Neither of us are engineers or technical. I know there are plants [and I have that list] that help clean and purify indoor air. Also the natural allergens in our geographical area are generally high.

To make air purified, clean, washed.
Wow, Plants, that is really interesting…Though…I actually am going to be in a basement area.
