People come up with these funny looking inventions where they'll tape filters together with a box fan so that they're filtering air in that room. and I Remember years ago when we would have these stand-alone type units. You could buy them online, You could have these units in the room where you plug them in the wall and they would clean the air. They were a novelty, especially with a lot of heating and air professionals.

There weren't many heating and air manufacturers out there that were taking any of this sort of stuff seriously, and as time has gone on, we've seen that change a little bit. We're starting to see some of the big name brands get into this sort of game where they're offering products where homeowners can be in control of how clean the air is in their home.
