Furnace filter to filter smoke.

[glen]

Pretty smoky so I picked up a furnace filter for smoke and am leaving the furnace on. I hope that helps.  
cheaper then buying a room filter.

Great idea...you want a filter with a minimum rating of MERV 13 to capture smoke particulate. Also, if the label says " electrostatic" that helps too.

Switching your return/drop from a 1" filter to a 5" thick media filter provides much better air quality, and can be done relatively inexpensively. Installing a UV light on your supply duct will also help.

Ultimately, you can install a HEPA system, but that can get pricey, however OHIP will pay for it if you have medically documented breathing issues.

I wouldn't spend a penny on a "room filter".

Switch the fan to on position rather then auto, if you want it to have any chance of helping 

hepa is really the only way to go

A few good points in that article...but it's from California, homes are a little different there. Often no basements and no duct work for forced air systems. Heat pumps and ductless split systems for AC are typical there, so a room unit may be the only option. I wouldn't waste my money on one up here if you have a tradional FA furnace like most of Ontario. Unless the room is hermetically sealed, and you never go in and out of it, not the best solution.

My daughter uses a hepa room filter because she has a rabbit and her dog in there at night with the door closed. It has helped with her allergies and the white noise of the fan helps her sleep..

We have a portable HEPA filter unit in our living area to help with my wife's COPD. We have a open plan so the kitchen and dining area are connected. It seems to work quite well. It has 3 speeds indicated by blue, orange, or red indicator lights. It runs continually on low(blue) and is almost silent. Sometimes when we are cooking, esp if we are frying, it will kick into orange or even red for a little while before reverting back to blue. I suspect that it does that faster than our furnace filter would clean the air in the whole house, which is about 3 times the volume.
