As a relatively new home owner, I am learning about different systems....a company tried to sell me a home air purification system (hepa filter, uv light etc on the furnace). I am having trouble finding comparables and am wondering if others on CalgaryPuck have done some research or had this type of system installed?
so, my questions are:
Is it worth it to have this type of system installed?
what are the annual costs of upkeep/electricity etc?
how much did you pay?
does it meet expectations?
are you happy with the company that installed/sold you the system and their services?

Thanks in advance, and Go Flames Go!
