When you're in the comfort of your own home, you should breathe easy—but ultimately, your living space might make it hard to do so. Indoor air pollution is a serious problem, and the United States Environmental Protection Agency reports that some pollutants, including common allergens like pet dander and mold, can exist at two to five times higher concentrations inside compared to outside. That's why it's important to consider the air quality where you spend the majority of your time, especially if you deal with asthma, allergies, or just simple congestion. Luckily, an air purifier can be a budget-friendly and effective solution.

On Amazon, shoppers have specifically praised Rigoglioso's small air purifier ($40;, which is USB-compatible and perfectly sized for a nightstand or desk. Standing a little over 9 inches tall, the device is more compact than most purifiers on the market, but it's powerful enough to clean the air of a small room and leave it smelling fresh.

"I bought it for my home office. I've only had it a few hours and I can already tell a difference in the air quality walking into the room," one reviewer wrote. "My only regret is that I didn't buy it sooner."

The Rigoglioso air purifier contains a HEPA (high-efficiency particulate air) filter, which removes at least 99.97% of dust, pollen, mold, and bacteria from the air, according to the EPA. So if allergies or odors have proven to be a particular problem in your living space, this purifier could be your simple fix.

Some have even seen a reduction in their congestion, allergies, and asthma symptoms once setting up the purifier. "My daughter and I have severe asthma and are allergic to dust. I've had this thing for about two months now and can feel a huge difference whenever it's on," one five-star reviewer wrote.

"Between allergies and odors from four teenage athletes living in my home, this device was a game changer," wrote another shopper. "My nose is less congested, sports gear odors are less potent, and breathing is much easier."

The purifier emits a quiet white noise sound that some reviewers call "soothing," as well as a discreet blue light, but most shoppers say that it's not noticeable enough to be distracting. In fact, many have noted that they bought the device specifically to improve their sleep. "After using it every night on my nightstand, I no longer wake up with a stuffy nose," another five-star reviewer wrote.

To buy: Rigoglioso Air Purifier for Home, $40;

To set up the air purifier, simply plug it to a USB port and press the power button on the top. You can also put the device in sleep mode by pressing this button twice—this will reduce the brightness of the light on top of the purifier and automatically turn the device off after eight hours, if you don't want it running 24/7. The Rigoglioso model comes with a filter, but you'll have to swap in a replacement filter ($13; every six months to ensure that the purifier continues functioning properly. Some reviewers, especially those with pets that shed a lot, recommend replacing it more frequently.

With over 1,500 five-star reviews and a $40 price tag, this air purifier is a budget-friendly buy that can make a major impact in any living space. Sometimes, serious relief comes in a small package.
