The great reviews are awesome and all - but c’mon - 200 sq. ft.?? This thing is nearly useless unless you put one in every room… Particularly here in FL where single-story homes with 20ft ceilings are the norm. This thing would make fresh air in one corner.
Put your money toward the install of a whole-house filter…
Ah yes, but if you live in a 1941 home with radiators in winter, the wartime-frugal smaller rooms and lower ceilings, that’s a good size for a bedroom cleaner if it’s quiet enough. Our bedroom is ~12x15. I’m burnt on our current bedroom cleaner, so if the filters are cheap enough I might bite.
If all your temp control goes through vents and a heat pump, though, I’d certainly agree with you.
Hey, has anyone found how much replacement filters are going to cost? I found one replacement pack on amazon for $94. You might as well get a new if the replacement packs are that much.
Alternatively, you could try attaching a HEPA furnace filter to the back of a standard box fan, and see how that works out. It will clean air pretty well.
Note that the description says “HEPA-type”.
This means it’s not actually HEPA.
While it’s probably “good enough”, HEPA is a technical specification that means you know what level of filtration you are getting. A product cannot be labeled HEPA unless it meets the HEPA standard.
HEPA matters because it filters down to a particle size that captures most airborne objects that can cause you discomfort. Filters that do not meet HEPA may allow airborne viruses and mold to pass through.
However, particulate filtration does not address gaseous irritants. For that, you need activated charcoal/carbon. On top of that, you need a LOT of carbon because most household filters only include a bare sheet of carbon that becomes useless after a week.
So, if your goal is to mechanically filter air for your health needs, there are 2 parts:
HEPA - Capturing particles so they are no longer floating around.
Activated Carbon - Capturing odor molecules in the porous surface of carbon so those odors don’t recirculate.
I have doubts that a Lasko unit achieves either of these. HOWEVER, the Lasko unit is probably still acceptable for capturing standard household dust and pet dander and hair. These irritants are large enough that they get caught in most filters (HEPA or not).
Know what you’re buying when you spend $100+ on an air filter. Sometimes you only have to spend a little more to get a real deal filter.
