Up to 1,850-Square-Foot Coverage

Before settling on a particular air purifier model, it’s important to know how far the device can reach. According to Instant, the same brand that brings you top-quality slow cookers, the AP300 has a maximum reach (1 air change per hour) of 1,850 square feet, making it the perfect purifying device for home offices, small businesses, and dorm rooms.

However, Instant recommends placing the AP300 in 388-square-foot rooms for better results (5 air changes per hour).

3-in-1 Filtration

So, how does the AP300 clean indoor air? It utilizes a 3-in-1 filtration system that captures ultrafine particles. The first line of defense is an activated carbon filter that refreshes the air by trapping odor molecules.

The second filter is an H13-grade HEPA Filter, that traps particles as tiny as 0.3 microns with 99.97% effectiveness. Finally, suctioned air passes through an antimicrobial filter that captures and destroys microscopic organisms, including viruses.

Optional Plasma Ionizer

To make the AP300 even better, users have the option of activating the AP300’s plasma ionizer. The ionizer discharges negatively charged ions into the air that latch onto dust, bacteria, and other allergens, allowing them to adhere to the filters more easily.

Anything that doesn’t get sucked by the AP300’s fan will land on the ground for easy cleanup later on instead of remaining airborne.

24/7 PM 2.5 Air Quality Monitor

Like any smart air purifier, the AP300 comes with a highly precise air quality monitor. The sensor uses LEDs to inform the user of indoor air quality (white for good, orange for fair, and red for poor air quality).

When you activate Eco Mode, the sensor will instruct the motor to turn on and off, depending on how polluted your home’s air is. This is an ultra-convenient feature that pretty much eliminates the need for users to mess around with the AP300’s control panel.

Auto-Sleep Mode

The AP300’s Eco Mode has one huge perk that’s not available in many competing air purifier models. When the sensor detects an absence of light, it’ll automatically assume that it’s nighttime and cause the light indicator to turn off.

However, the AP300 will continue working in the dark—just not produce distracting light that can interfere with your beauty sleep.

Cylindrical 360° Design

As you can see, the AP300 is shaped differently from most air purifiers out there. It has a cylindrical base with one massive air intake port on the side that suctions air for cleaning.

Purified air is then shot upward and distributed to all four corners of a room, spreading fresh, breathable air everywhere.

Verdict; Compact, Heavy-Duty, Smart—A Must Have!

All in all, the Instant AP300 Air Purifier is certainly a capable air purifier that can get rid of ultrafine particles in your home with ease. The powerful fan allows it to purify the air in 1,850-square-foot areas, making it ideal for large rooms and entire apartments.

If you have pets, love experimenting in the kitchen, or live with a smoker, do yourself a favor and get the 3-in-1 AP300.

Air Recommended Air Purifiers

Our Pick Perfect for bedrooms, playrooms, and living rooms, the Coway Airmega AP-1512HH is one of the best-performing, most durable, and most economical purifiers we’ve tested.

Most Popular The Levoit Core 300 air purifier has some strong suits, but in our opinion it falls short of carving out a meaningful niche for itself. Its ideal use would be in a small bedroom occupied by someone who is sensitive to noise.

Also Great With high end air cleaning performance and a whisper quiet fan, the Winix 5500-2 is the perfect combination of power and finesse. It cleared airborne particulates out of our smokey testing room faster than any other model.

Best of the Best If you have a large space you want to remove irritants from, We recommend the Airmega 400S. All of Coway air purifiers do an excellent job of attacking indoor pollutants, and we highly recommend any of them. The 400S is designed to accommodate large room sizes.
