Best HEPA Air Purifier for Home?
Same situation. Analysis: 1. Fan noise is primarily determined by turbulence, which is directly correlated with fan speed, which (all else held equal), is linear to to fan rotational speed. Small fans must rotate faster to move the same CFM as a large fan. And a filter can't be aerodynamic. TLDR: Buy big. 2. The wirecutter did a review and all of the fancy technologies (Molekule, etc.) didn't work as well as HEPA. 3. Winix has a fancy ionic mumbo-jumbo but it just wastes power in the WireCutter's tests. 4. The thing that improved performance 50% on most HEPA filters was to have a fuzzy gasket around the HEPA filter to prevent air from going around it. Simple and not sexy. 5. I used to add gasket tape around my Winix but after calculating TCO on all my filters, \*I standardized on Coway AirMega 400/400S (the smart ones that can be monitored online for filter replacement, particle count, etc.). They work like a champ\* - not one failure in at least 5-25 years of operation (multiple filters at play) 6. All other things equal, I'd assume high RPMs lead to faster motor death. The windings on small motors are more likely to short out from dust and whatnot. Bearing surfaces more likely to burn out. 7. You can't get the same number of air changes from your central HVAC, and absent special engineering the increased difficulty of going through a high MERV filter is going to kill your motor (ask an HVAC tech for specifics on pressure differentials). Therefore, those filters are to protect the equipment, not purify your air. Save the money and buy hard floors (CoreTec Luxury Vinyl Tile is fantastic and cheap to install, the marble looks and feels amazing) TCO Analysis: 1. Coway Airmega 400S takes a $45 HEPA filter replacement cartridge every year, but consumes \~64W of power, for a yearly operating cost of $45 + 64W \* 1kW/1000W \* 8760 hr/yr \* $0.12kWhr = $100/yr. Each can cover 1560 sq ft, so \~$0.06/sq ft/yr. 2. WINIX WAC9500 pet ultimate filter takes a $89 “filter B” set, and a $44 HEPA & charcoal “filter A” set every year. That’s $133 + and a power consumption between 6 and 70W, so let’s say \~50W, which is about $52/yr for a TCO of $185/yr for 284 sq ft, so \~$0.65/sq ft per year. 3. A small honeywell air filter took $47 in charcoal and HEPA filters in two years, but takes 84W of power, so $88 in energy, or $132/yr and it’s quite noisy and only covers a single room (310 sq ft), so \~$0.42/sq ft per year.

Need Help Choosing the Best Air Purifier for Allergies, True HEPA and Quiet
Austin Air is overpriced, and sounds like a jet aircraft taking off. For contrast, look at the Coway Airmega 400, or the Airmega400S (for "Smart") if you want detailed sensor readings/remote operation. For that size room, you could even start with the Coway AP-1512HH and then add a second unit if the one wasn't enough.
