Twenty-seven decibels and an app. The 130i is the only PuroAir with Wi-Fi, and it is quiet enough that the bedroom is the point rather than a compromise.
The 130i is the smart one. It is the only unit in the PuroAir line with Wi-Fi, an app, and voice control through Alexa or Google Assistant, which means fan speed and scheduling from anywhere and a filter reminder that arrives on a phone rather than as a light on the front panel. It runs the same three-stage stack as its bigger siblings, a pre-screen followed by HEPA and activated carbon, filtering PM1, PM2.5 and PM10 down to 0.1 micron plus VOCs.
The specification that earns it a place is noise. PuroAir publishes 27 dB at the lowest setting, four decibels under the 400, and the brand positions that as usable white noise for a bedroom. At 4.39 lbs and roughly 8 by 8 by 13 inches it is small enough to move between rooms, and at 18W it is the cheapest of the three to run continuously. It carries ISO certification and CARB compliance, and the same two-year warranty that extends to lifetime while a filter subscription is active.
The limit is coverage. Six hundred square feet is genuinely a bedroom, a nursery or a home office, not a floor, and pushing it into an open living space is the mistake to avoid. The brand-level caveat also stands: independent testers including HouseFresh have questioned whether PuroAir's real-world clearance matches its coverage marketing, and no CADR or HEPA grade is published for this model either. Size up rather than down.
A bedroom, nursery or home office under 600 sq ft where quiet operation matters most, and for anyone who wants app scheduling and voice control rather than a front-panel button.
The room is larger than about 600 sq ft, where the 240 or 400 is the honest answer. Also skip if you want a published CADR or HEPA grade, or if you have no interest in connecting an air purifier to Wi-Fi at all.

PuroAir PuroAir 130i - buyer FAQ
How quiet is the PuroAir 130i really?
PuroAir publishes 27 dB at its lowest fan speed, which is the quietest figure in the line and roughly the level of a whisper or a quiet library. That is four decibels below the 400. The brand markets it as white noise suitable for sleeping, and the sleep mode is one of four fan modes alongside low, medium and high.
What does the app actually do?
The PuroAir app handles fan speed and settings remotely, sends automated notifications, and reminds you when a filter is due. Voice control runs through Amazon Alexa or Google Assistant. The 130i is the only model in the line with Wi-Fi and Bluetooth; the 240 and 400 are manual units with indicator lights instead.
What room size does it cover?
PuroAir rates the 130i to 600 sq ft per hour, verified 2026-08-17 on the brand product page. That is a bedroom, nursery or home office rather than an open-plan space. For 1,000 sq ft step up to the 240, and for 2,000 sq ft the 400. As with every unit in this line, treat the coverage figure as a best-case ceiling and size up rather than down.
How much does it cost to run?
It draws 18W, the lowest in the line, against 80W for the 400. Running continuously at 18W is roughly 13 kWh a month, so a few dollars at typical US electricity rates. The larger ongoing cost is filters, and the subscription that lowers the purchase price to $119.99 from $124.99 also converts the two-year warranty to a lifetime one while it stays active.
