This air purifier also has an Energy Star certification, so you don't have to worry about your energy bill spiking every time your device is running. It even includes a built-in fan, helping to circulate air throughout the room and keep you cool.

This is where the PureZone really shines, as it is nearly silent on its low setting. It emits a fairly low-pitched hum on medium and high that certainly isn't offensive, and some may even find it to be a pleasant white noise. This again adds to its usefulness as a small bedroom machine, as you'll likely be sleeping in close vicinity to the machine. If quietness is your first consideration in buying a purifier, we think the PureZone is the best deal you're going to find. Ease of Use Understanding the air quality in your home can feel confusing and overwhelming, but the Levoit Core 400S Smart True HEPA air purifier makes it easy to understand. The lightweight model works in rooms up to 990 square feet, and it uses three different filters to remove dust, bacteria, pollen, smoke, and more from your home. One of our most FAQs is “ Do air purifiers use a lot of energy?” In fact, air purifier must be used for a long time to be efficient. And power consumption is one important criteria to review how much energy this air purifier will consume. Keep in mind that this unit is not Energy Star certified, so it will consume more energy than other devices of the same size with Energy Star certifications. However, because it’s a smaller device than air purifiers for large rooms, it may still cost less to operate than a bigger unit. It comes with a three-stage HEPA filter, and there are three customizable options for replacements when it's time for a new one: a pet allergy filter for those with pets, a filter designed to absorb toxins, and a smoke-removing filter.However, its energy consumption is really low and you shouldn’t worry about running this air purifier. Pure Enrichment PureZone Mini is designed only for personal use, though the company confirmed it can run in any room of 54 square feet. Again, I recommend you should use it in very small places. The PureZone air purifier is made by Pure Enrichment, a brand from A Bear Down Brands, LLC, based in California. The company produces various home air quality products, from humidifiers to heat therapy. According to Linkedin, they were founded in 2010 and currently have 55 people working for them. Product Details: Room Size: 219 square feet | CADR: 240 m³/h | Noise Level: Between 48.5 and 55.4 decibels | Dimensions: We have been testing air purifiers in our Des Moines, Iowa lab for over a year, using a pre-determined methodology to put some of the best air purifiers to the test and see which ones improved the air quality most efficiently. We exposed the air purifiers to smoke, artificial pet hair, and dust in an enclosed space, then tested out different settings and compared the air quality of the room periodically throughout the test using an air quality monitor. This helped us determine which models were able to remove particles in the air, how long it took to do so, and what particles each purifier was unable to capture.

Battery lasts a decent amount of time with 12 hours on low, or 2.5 hours on the highest speed What We Think Could Be Better: A benefit of small dehumidifiers is that—even though you might have to empty them more often—they’re usually much easier to dump than larger models, given their tinier collection tanks. Most can operate for a day or two before filling up completely. If you don’t want the hassle of emptying out a tank, look for models that come with hoses or continuous drainage options. The best air purifiers will have built-in HEPA filters, which can remove 99.97% of pollen, dust, airborne contaminants, mold, and any particles that are 0.3 microns, according to the EPA. Since airborne particles that are 0.3 microns in diameter are the most penetrating particle size, HEPA filters will work even better on particles larger or smaller than this. However, you'll want to make sure the purifier you're buying has a HEPA filter and not another type of filter, as other filter types may not work as well.

True HEPA filter – A True HEPA Filter can reduce 99.97% of down to 0.3 microns all contaminant particles like dust, dust mites, pollen, pet dander or even mold spores. The PureZone also offers a UV light that is meant to kill microorganisms in the air moving through it. While this technology has been proven effective in industrial-scale units used in hospitals, this technology is largely unproven in household units. Also, UV lights can sometimes produce ozone, which is a lung irritant. If you want to err on the side of caution, you might want to keep this feature turned off. We used a sound level meter to record noise levels when running the PureZone Mini at its lowest and highest speeds. If you own pets, you already know how much work it takes to keep a tidy home with a furry friend or two sharing your space. Since pet hair and dander can have a negative impact on your air quality, a reliable purifier can capture and remove allergens from the air you breathe. We chose the Rabbit Air A3 as the best air purifier for pets, because it’s highly customizable, with a specific filter for pet allergies, and very effective.

While this air purifier is advertised to work well in rooms up to 990 square feet, it will take more time for the device to improve the air quality in larger rooms. We recommend purchasing multiple air purifiers if you need to use them in a space larger than 900 square feet for the best results. Getting rid of smoke from your home can be a difficult task, whether you're near someone who smokes cigarettes, you live in an area impacted by wildfires, or your home is exposed to smoke from another source. Since simply putting a wall between you and the source of smoke isn't enough to stop harmful particles from getting into your airways, purchasing an air purifier can be one helpful solution. Settings: A wide range of settings is not necessary in most cases, but some models include different filters for different needs, or different strength levels which can affect the noise level in the room. As dehumidifiers remove moisture from the air, they store the water in an on-board tank. Models with small tanks require more frequent emptying, but large tanks may be heavier and harder to carry. Most dehumidifiers automatically turn off when the tank is full so the water doesn’t spill over.During our tests, the Bissell Air400 Professional air purifier performed the best against smoke out of all the devices we tried. After adding smoke to an enclosed space with the air purifier, the device accurately registered a hazardous level of PM 2.5 on its screen, but after just five minutes it reduced the levels by more than 990 points to a healthy level again.

When shopping for any kind of air purifier, portable or otherwise, you’re likely to come across a variety of acronyms and certifications, which may or may not read like gibberish to you. If you’re looking for the best portable air purifier, you’ll want one that comes with the same high-quality certifications as a full-size model, while keeping in mind things like size and noise level to make the device practical for bedside or desktop use. What to Know Before Buying an Air Purifier Noise Level: Especially if you’re using the purifier at bedtime, we like to prioritize purifiers designed for especially quiet operation. Though we liked the compact size and lightweight design of this portable air purifier, we found during testing that it wasn't very effective at removing particles from the air. While many other models could reduce PM 2.5 levels from hazardous to good in under 10 minutes, the Pure Enrichment mini air purifier levels remained hazardous (though they decreased slightly).
