desktop air purifier

A desktop air purifier might seem like just a nice-to-have little gadget. Sort of like your novelty mug, or a desk toy given to you by your Secret Santa. That is, until you consider this—you may spend around 90,000 hours of your life there! If that makes you wonder just what you’re breathing in, you’re not alone. Sales of desk air purifiers have increased in recent years, both for work-from-home warriors and those in offices. 

But with so many desktop air purifiers out there, how can you pick the perfect one for you? Breathe easy, dear reader—below, we’ve rounded up reviews for some of the top desk air purifiers out there.

All About Air Purifiers

Just what does an air purifier do? These devices use both filtration and advanced air cleaning technologies to remove pollutants, such as  toxins, dust, allergens, and odor particles from the air. That leaves your air fresher, cleaner, and safer to breathe.

How a particular desk air filter does this can change. Some filters rely on a fan and one or several filters. This fan pulls the air through the filter, trapping fine particles inside. Others might neutralize or ionize these harmful particles, while not filtering the air at all. Some brands can even trap or kill harmful airborne bacteria.

What to Look For in a Desktop Air Purifier

When shopping for a desk air purifier, you have a lot of options out there. It can be confusing to know where to start. To find the best desktop air purifier for your desk, there are a few things you should consider:

  • Room Size: Air purifiers are not a one-size-fits-all device. To be sure you’re getting the benefits of clean air, you should make sure that your desk air filter can handle your space, without being overkill.Determine the square footage of your room or office to make an informed and reasonable choice.
  • Square Footage = Length (ft)  x Width (ft) Ex. — 12 x 20 = 240 sq. ft.
  • ACH Rating: As you shop for the best desk air filter, you might come across the ACH rating. Standing for “Air Changes per Hour,” the ACH rating measures how many times your device will purify the air volume in your room each hour. For example, a desktop air purifier with an ACH value of 4x will cycle the air 4 times. The higher this number, the more efficient the device, and cleaner your air will be.
  • HEPA Filters vs. The Rest:  Known as the ‘gold-standard’ for air filters, HEPA stands for High Efficiency Particulate Air [filter]. It is an efficiency standard carefully monitored by the Environmental Protection Agency, and other government groups. To be named a HEPA filter, a filter must remove 99.97% of particles from the air, and anything above 0.3 microns. For some comparison, one of your hairs is a HUGE 70 microns thick. Many cheaper products try to cash in on this quality by using “HEPA-like,” or “HEPA-type filter,”—but don’t be fooled. When shopping for your desktop HEPA air purifier, always look for the true HEPA designation. With regular changes, these strong filters will keep your air clean and clear.
  • Other Features: Think about what is important to you in your desk air filter. Would you like to be able to set a timer? Connect your air filter to your smartphone? How about a nightlight, or a super-quiet fan? Make sure your purchase is the best desk air purifier for your needs.
