Winix P150 4 - 40 W power consumption is no doubt lesser than its higher end series although you would only see the difference in long-run. Compared with other small category air purifiers, this ENERGY STAR rated unit power usage is still within reasonable tier. 26 - 50+ dB noise level is subdued at low to medium fanspeed while at high and turbo speed there is a common humming loud noise though still bearable in our book.

^ Winix P150 replacement filters estimated cost
As mentioned earlier, Winix P150 reasonably low price tag with the bundled set of features is the air purifier key selling point. If you could top up a little bit more, we would personally recommend you to go for the mid-range Winix P300 that comes with better CADR and airflow delivery rate, 3 years warranty plus a remote control. Filter replacement cost is tag under OK as the bundled package (4 carbon filters and 1 HEPA filter) would last through a year. If you are OK replacing the filter on a quarterly basis, no doubt Winix P150 would serve you well. For the best deals and discount available online, go to Amazon via our affiliate link below.

The challengers

Holmes Tower Air Purifier HAP9422-UA

Again cheaper, marginally better in coverage and CADR plus an optional ionizer. Lacks option such as digital display, air quality sensor.
