Whirlpool Whispure 450 air Purifier Review

Retail Price: $299-$315

OVERVIEW:The Whirlpool Whispure 450 Air Purifier is one, that for some strange and unknown reason, Consumer Reports loves. Maybe it's the Whirlpool name, the energy-saver aspect, or the fact that it is primarily HEPA. There are some facts that CR overlooked (not sure why?) including exorbitant replacement filter prices (over $100). But it is a decent HEPA-based air purifier if you're looking for dust and pollen removal and don't mind the noise (it's loud, even on low). I have a big issue with that because consumers often buy an air purifier for a reasonable cost only to get "ripped-off" when they buy a filter.

The whirlpool whispure 510 air purifier 450 is a 3-stage air purifier which covers 400-440 square feet (depending on whether your read the manual or their website). The carbon filter on it is very thin, which means that it won't work for long (3 months at most) and then it's $25 to replace (ouch!). the HEPA is a good size so it shouldn't have a hard time covering the 400 square feet. the 5 Year Warranty is also good. I haven't had time to pull the fan motor out (I like to see why it's so loud) but will get you that video shortly.
