More like than not this would not be a very good product and would likely not make any notable difference in air quality. The lack of any technical information, combined with the price, suggest this. If price is an issue, I would suggest constructing a Corsi-Rosenthal Box, which can be put together for the cost of box fans, MERV-13 or higher furnace filters, and tape. These move large quantities of air using filters of known level of performance to make a huge difference in reducing particle counts.
