The 5 Best Air Purifiers for Home Offices, Quiet Enough for Calls, Ranked & Reviewed

Our verdict: A HEPA purifier with an air quality monitor, Auto and Eco modes, a timer and a 3-year warranty.

The Coway Mighty AP-1512HH uses a HEPA filter for smoke, allergies, pet dander and odour, with an air quality monitor, Auto and Eco modes, a timer, a filter indicator and a 3-year warranty. It is rated for up to 1,748 square feet in an open room.

It takes first place because Auto and Eco modes suit an office. Auto mode raises the fan when the air quality sensor sees dust or smoke, and Eco mode shuts the fan down after the air has stayed clean, which keeps the room quiet when you need it to be. The filter indicator removes the guesswork about replacements. The 3-year warranty is the longest in this group.

Buy it if you want automation and a long warranty. Skip it if you need the cheapest unit.

Our verdict: A compact purifier with an H13 True HEPA filter and a quoted 24dB noise level.

The LEVOIT Core 300 has an H13 True HEPA filter that the listing says removes 99.97 percent of dust, smoke, mold and pollen particles, with a quoted noise level of 24dB.

It ranks second because a quoted 24dB at the lowest setting is as quiet as these purifiers get, and low noise matters most on a desk. The compact body fits a corner or a shelf. The cost of compactness is coverage, as it suits a small room rather than a large studio, and it has no air quality display.

Choose it for a small office or a desk-side unit. Skip it if you want a monitor and automatic mode.

Our verdict: A smart purifier rated up to 1875 square feet in an open room, with app control.

The LEVOIT Vital 200S-P is a smart air purifier rated for up to 1875 square feet in an open room, with app control.

It ranks third because capacity is its edge. A higher rating gives headroom in a furnished or crowded home office, where furniture and closed doors reduce effective coverage. App control lets you schedule it to run before you start work. The unit is larger than the Core 300 and costs twice as much.

Buy it for a big or cluttered office. Skip it if the room is small.

Our verdict: A compact Levoit purifier with smart and voice control for hands-free changes.

This compact Levoit purifier offers smart and voice control and is aimed at bedrooms, pets and dorm rooms.

It ranks fourth because voice control is handy during calls, when you can lower the fan without leaving your seat. It is affordable and compact. The listing says nothing about the filter grade or noise level, so we cannot compare it with the Core 300 on those points.

Choose it for hands-free control in a small room. Skip it if you want a stated noise level.

Our verdict: A budget-friendly, compact HEPA purifier for smaller offices.

The Membrane Solutions MSA3 is a compact HEPA air purifier described as budget-friendly.

It ranks last because the listing gives few specifics beyond HEPA filtration and a compact body. It will suit a small office on a tight budget, but there are no stated noise or coverage figures, so you are less able to judge it.

Buy it for a small room on a budget. Skip it if you want documented figures.
