How important is good indoor air quality, you ask? Well, unless you enjoy inhaling insulation, paint fumes, and carbon monoxide – all of which are most likely lurking unknowingly in our households – then you needn’t worry about anything at all.

Inofia Air Purifier with True HEPA Air Filter Review

However, if yours and your family’s health is of the utmost importance, you’ll be glad to know that we can eliminate these airborne toxins and much, much more with a simple air purifier. In this article, we’re going to a close look at the Inofia PM1539 Air Purifier, one of the best-working models made by a relatively lesser-known manufacturer.

Made for Spacious Areas

So you need an air purifier to clean the air in a wide area, and you don’t want to invest in multiple miniature air purifiers to do the job? Then have we got good news for you! The PM1539 is designed to filter the air of areas as large as 1,056 square feet. By placing a single PM1539 against the wall, you can ensure that multiple rooms or an entire floor’s air is constantly purified to give your family the freshest breathable air possible.

Here’s something that might disappoint: the PM1539 only has two filters to eliminate microscopic particles and odors. The first line of defense is an activated carbon filter that stops larger particles and odor molecules in their tracks. If you live with a smoker or like to experiment in the kitchen, then the PM1539’s odor-removing filter is exactly what you need. As for any smaller particles that manage to wriggle their way free of the activated carbon filter, they stand no chance against the final boss, which is the…

Inofia Air Purifier with True HEPA Air Filter

True HEPA Filter

Its impossible to understate the awesomeness of True HEPA Filters. Designed for industrial purposes, True HEPA Filters have found their way into everyday home appliances, such as vacuum cleaners, air conditioners, and air purifiers. True HEPA is the only filter that guarantees that up to 99.7% of particles as small as 0.3 microns in width will never find their way into your lungs. True HEPA Filters require constant monitoring to ensure that they’re working optimally, and replacements can be on the costly side, but when it comes to purifying performance, there’s nothing that comes close to it.

300+ CADR Ratings

Inofia has willingly put the PM1539 to the test by having its CADR ratings measured. The PM1539 scores 330 CFM on all three measurements (smoke, pollen, and dust), practically promising that all airborne pollutants in a 1,000-plus-square-foot room is completely gone for good.

Smart Air Monitor and Auto-Mode Convenience

The PM1539 comes equipped with a built-in Smart Air Monitor. The monitor alerts users of how polluted indoor air is by flashing LED lights. When auto-mode is activated, the PM1539, without needing guidance, will automatically switch to one of the five available fan speeds to get rid of pesky airborne pollutants as efficiently as possible. So basically, after plugging the baby in and turning auto-mode on, all you have to do is check whether the filters need to be replaced. Talk about convenient!

Wi-Fi Connectivity

To make the PM1539 even more convenient to own and operate, the air purifier can connect to your home’s Wi-Fi and receive instructions via your smartphone. Just download the app, simply named APP, on Google Play or the Apple Store and choose whatever settings you’d like with a tap of the phone’s screen. The app only works on 2.4G Wi-Fi.

24-hour Timer

If your home’s Wi-Fi is down or you don’t have 2.4G connectivity, worry not, dear reader, for the PM1539 has a built-in timer function. The PM1539’s timer can be set from anywhere between 1 and 24 hours, giving you the peace of mind of knowing that your air purifier is working without fail in the background.

Quiet as a Mouse

Most air purifiers produce a ton of noise while cleaning indoor air. This is not the case with the PM1539 – from sleep mode to speed 5, the air purifier generates only between 27 and 52 decibels, roughly the same volume as background noises inside of your home. You’d have to stick your ear pretty close to the PM1539 to be annoyed by its constant droning.


After reading our review, hopefully, you realize just how great the Inofia PM1539 is. It comes with all of the bells and whistles you’d ever need, plus the convenience-adding features (APP, timer, Smart Air Monitor and Auto Mode) have exceeded our expectations of this product.

If there were one thing we could change, it would be adding a dimmer to the LEDs since having them off completely at night can make finding the on and off buttons a challenge. Hey, no air purifier is perfect, but the PM1539 comes as close to perfection as we can imagine.
