Whether you're on a life-long quest to keep your apartment fresh, or trying to rid your space of the smell of smoke, the best small air purifiers can help — and you don't even have to donate all your floor space to the cause. Many of these models feature HEPA filters to remove at least 99.97% of particles of 0.3 microns or larger including dust, pollen, and even bacteria.

Unfortunately, most people feel they have to sacrifice quality for size. That's where these devices come in. There are plenty of tiny purifiers that can tackle large spaces, some that are designed to eliminate germs, and still more that work well on pet dander.

Personally, my top priority is keeping the air in my home as healthy and dust-free as possible. I live in the basement apartment of a house that was built decades ago and was heated with coal for most of its existence. Even though the apartment itself is new construction, I can't go more than two days without getting a layer of soot over all my furniture. For you, your priorities might differ.

But whether you're looking for the absolute smallest purifier that removes 99% of dust, or a powerful three-in-one purifier that eliminates bacteria, this list has what you're looking for. So, start scrolling. The best small air purifiers still pack a purifying punch, all despite the fact that you can neatly tuck them into a corner or place them discreetly on your bedside table.


The Best For Allergies: Honeywell Air Purifier

It may look unsuspecting compared to other purifiers, but this one from Honeywell is surprisingly powerful. It can tackle molecules that are 250 times smaller than the average human hair, all thanks to its true HEPA filter. In a 310-square-feet room, it can filter and circulate the air an impressive five times in an hour. If you have a specific issue you're trying to fix, Honeywell is also one of the few models that gives you different modes — germs, general clean, allergens, and turbo. "I'm in an apartment, so it's more than enough to handle my living room," says one reviewer who saw a difference in their allergies less than an hour after setting it up. No wonder it has a 4.7-star overall rating. Plus, it’s the most commonly recommended brand by allergists.

Helpful review: "A friend of ours suggested buying one of these after a serious bout with a respiratory illness - it really helped him. After trying one, I now own 3 of these. A big one in the living area, a medium sized in the bedroom, and small one in the RV. I'm also buying one for my elderly father for use in his house. I am amazed at the amount of dust and stuff that this unit catches in just the prefilter. It has seriously cut down on our nasal symptoms due to allergies and colds.”

Thanks to its fine preliminary layer, true HEPA filter, and activated carbon layer, this air purifier is especially effective when it comes to trapping airborne allergy triggers like dust mites, pollen, smoke, mold, and pet dander — and at less than $100, that's a huge value.

I have to say we were both surprised by this air purifier. We got the black one, it looks great in his room, it's also quiet and works very well. I have a small kitchen so I decided to put it through the ultimate test, can this product remove odors as stated in the reviews? Well it sure did, not only from the kitchen but there wasn't any lingering bacon smell anywhere in my apartment.”

Furthermore, the fabric filter is totally washable and can be changed to a different color to suit any decor.

We have this in our bedroom, and within 4 hours there was a VERY noticeable difference in air quality, total 180 by the next day.
