Now, let's get on with the article.


The Three Musketeers III M's AM-1A Air Purifier is the first product on the list. And, seeing how the name is a mouthful, we will refer to it as the AM-1A air purifier going forward. With that out of the way, you should know that the AM-1A has a lot going for it. For starters, the air purifier makes use of replaceable HEPA filters that, in theory, can remove up to 99 percent of indoor pollutants. sd

This includes particulates that are as small as 0.3 microns, mind you. What's more, the AM-1A's HEPA filter can last anywhere between three-six months, thereby ensuring you don't have to swap out a filter every few weeks. The unit is quite portable too and measures 3.55 inches in diameter and is 6.69 inches tall. As such, the device won't take up too much space on your work table.

Coming to the meat of the matter, the unit covers an area of around six square meters. Interestingly, the device requires a low input of just 5V to function properly. More to the point, the AM-1A's fans don't make a lot of noise either and top out at 30 dB. This reminds us, the air purifier comes with three fan speed presets as well.

Unsurprisingly, the majority of customers are seemingly impressed with the AM-1A's feature set, with many citing an improvement in the air quality after using the device. Needless to say, the AM-1A is among the best desk air purifiers you can buy.


Pro Breeze has a fantastic Air Purifier up for grabs too. The company's Mini Air Purifier ships with a HEPA filter as well. That's not all, as the purifier's HEPA filter comes with a pre-filter of sorts that captures larger airborne particles as well.

As such, the device can filter out up to 99.7 percent of airborne particulates, including dust, pollen, smoke, and pet dander. Needless to say, the air purifier is a great buy if you have pets in your household. Moving on though, the air purifier also comes with night light functionality. To that end, the unit emanates a diffused blue light of sorts that accentuates the design of the air purifier tenfold. It can also be used to create an ambiance in and around your work desk.

The icing on the cake is that the air purifier comes with easily replaceable HEPA filters. So, you won't have to toss the device once the filter gets too dirty. And, going by the customer reviews, the Pro Breeze Mini air purifier seemingly leaves no stone unturned in the performance department either. In fact, several users cite that the purifier cleared nauseating air at their workplace. Some users even state that the air purifier helped them with their headaches, which is great.


OSIMO's A2 portable air purifier is no slouch either. To that end, the unit measures 6.3 x 6.3 x 7.9 inches and weighs just 1.44 lbs. Despite that, the device has an effective range of around 215 sq. ft, which is great. As such, the device will be able to clear out the airborne particulates in a small room or office space easily.

Since we’re on the subject, you should know that the device comes with an H13 HEPA filter that can remove up to 99.9 percent of air contaminants. That's not all, as the device boasts a three-stage filtration system comprising a preliminary sponge-esque filter followed by the H13 HEPA filter and an activated carbon filter. The carbon filter is a great addition as it can eliminate household odors, including the smell of cooking or smoking a cigarette.

The unit also comes with three different fan speeds and you can use the purifier in sleep mode, normal mode, and strong purification mode. It goes without saying that the fan noise is the loudest at 40 dB when the device is operating in the strong purification mode.

As for longevity, the company claims that the filters need to be replaced every six months. And, sure enough, the replacement filters are readily available as well. Suffice it to say, the OSIMO A2 portable air purifier is among the best desk air purifiers you can buy today.


Up next, is the Core Mini Air Purifier by Levoit. For the most part, the air purifier's features draw parallels from the alternatives prefaced above. With that said, the Core Mini has a few aces up its sleeves. To that end, the Air Purifier also doubles up as a makeshift diffuser for aromatherapy.

That's right, the Levoit Core Mini features a small slit of sorts that can be filled with your favorite essential oils. In doing so, the device will not only cleanse the air around you, but it will also sprinkle a tinge of your desired fragrance as well. Further, the Core Mini features a three-stage filtration system as well, comprising a pre-filter to trap dust, lint, and pet fur. Moreover, the device also gets a HEPA filter to capture microscopic particulates, along with an activated carbon filter that should help neutralize pungent odors.

Do note that the unit is the heaviest air purifier on the list. So, you might want to factor in the device's size if you’re working with a tight space. On the upside, the air purifier is whisper quiet and keeps the fan noise below 25 dB, which is great. Unsurprisingly, the Core Mini has amassed over 11.5K ratings, with the majority of reviews highlighting the device's excellent performance. Rest assured, the Levoit Core Mini is among the best desk air purifiers at the moment.


The LG PuriCare Mini is the most expensive air purifier on the list. Thankfully, the device's feature set will turn your frown upside down. We say this, as the device is the only ‘smart’ air purifier on the list that can give you detailed AQ stats as well as insights into the filter's health and the purifier's battery levels.

To do so, you will have to download the companion app which enables a plethora of smart features. These include the ability to get notifications to your phone and control the purifier's fan speeds from the comfort of your couch. More to the point, PuriCare Mini features two filters, namely a pre-filter and a HEPA filter. The two filters work in tandem to clear out up to 99 percent of airborne pollutants.

The unit is quite compact too and the device tips the scales at just 1.2 lbs. That's not all, as the device can be used for up to eight hours at a stretch too. It goes without saying then, that the PuriCare Mini's spec sheet reads like a dream.

So, what do customers have to say about the device? Well, you’d be glad to know that the majority of buyers have been singing praises of the PuriCare Mini's performance. Moreover, most buyers are in agreement that the fan noise isn't too loud or jarring either. Pool everything together and the LG PuriCare Mini is right up there with the best desk air purifiers.

Yes, any air purifier with a HEPA filter will remove harmful particulates from the air, which in turn will be better for your overall health.

As a rule of thumb, you should run an air purifier for at least 8-10 hours a day. You can even leave it on for the entire day if you so choose.

A device with a HEPA (High-Efficiency Particulate Air) filter is among the safest types of air purifiers as they can remove microscopic contaminants without emitting ozone.

If you work in a stuffy environment, then you must add a tiny air purifier for proper ventilation and filtration. The aforementioned devices should help you narrow down the search for the best desk air purifiers. Do let us know which device you snagged in the comments below.
