But the air purifier does not. So the gas furnace is creating negative air pressure whether or not there is an air purifier in the room. The most the air purifier would do is move air around (since it has a fan), but because it's a closed system, it's not going to change the pressure.

Sorry, still confused - your gas furnace will vent stale air outside (and probably draws in fresh air from outside) regardless of whether or not you have this air purifier (or any air purifier, for that matter) in your house.

Which one is better? Winix C535 or GermGuardian?

GermGuardian filters have to be replaced more often than Winix ones. I have three GermGuardian tower air purifiers, but I just bought this Winix because the cost of buying GermGuardian filters was getting too costly. Based on the sqft specifications, this one Winix (360 sqft) is going to replace two of my GermGuardians (180 sqft each). Cost for the Winix filter is $60 every year (once per year), while the two GermGuardian is $50 every 6 months for each air purifier, totalling $200 a year.

Winix blows GermGuardian out of the water in terms of yearly costs. As far as performance goes, I've only had the Winix for less than a day, but no issues so far, and the Winix seems more quieter than the GermGuardian. That's not to say that the GermGuardian is loud at all. I have no issues sleeping with it on.

I have a GermGuardian and my filters last about a year. I actually replace them before the unit tells me to. I guess it depends on how often you run it throughout the day. I turn it on for about 3-4 hours a day. GermGuardian recommends that the filters are changed every 6 months.

edit: I buy the filters at Costco or Amazon when there is a sale and pay about $34 for each filter.

Yeah, the GermGuardian filters can last longer if you don't have the unit turned on all day, but then you can make that same argument with Winix filters as well. At the end of the day, the Winix filters are far more cost-effective than GermGuardian ones. I really liked the GermGuardian units, but the cost savings per year is just too hard to ignore.

I was also buying the GermGuardian filters for $34 each the last couple of years, but it seems like the prices have jumped. The genuine "B" filters are now going for $50 each on most sites. I see Costco is selling 2 for $65, but who knows how long that will last, and like I mentioned, the one Winix unit replaces two of my GermGuardian units, so buying this one Winix for $180 is a no-brainer, since it already comes with two years of filter replacements. Two years of GermGuardian filter replacements would have set me back ~$280, assuming I can get them at $35 each, which isn't a given.
