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. The Veva model used very little wattage when running for 30 minutes, so we think this would be an excellent choice for saving money on energy bills down the line. The Dyson stood up incredibly well over six months of testing at home. Despite running it 24/7 for months, we had no issues with it and it continued to perform as if it were brand new. It made such a difference in our old, drafty house that we didn't notice our allergies acting up anymore after using it for several months. The air purifier cut down on pet dander in the air, while the humidifier kept the air moist enough to decrease dry skin. For even more detailed information and setting control, you can connect the device to the Dyson Link app or even pair it with your Alexa, Siri, or Google Assistant.

We raved about how quiet this machine is, even at its highest fan speed. During testing, the Dyson Purifier Cool did not make noises above 64 decibels—similar to the sound of a fan running on low. This means you'll be able to run it in the middle of the night without worrying about the noise disturbing you. Plus, the air purifier's night mode allows the unit to run at its quietest settings and even dims the screen so the light won't wake you. We used a sound level meter to record noise levels when running the PureZone Mini at its lowest and highest speeds.

Its sensors continuously analyze the air and diagnose pollutants in the room, then display live PM 2.5 levels on the screen so you can monitor your air quality in real-time. The HEPA filter will capture 99.97% of airborne particles from the air, then seal these particles away so they can't escape out of the device. We reported that after consistently using this air purifier, we experienced fewer allergy symptoms than usual. Indoor air quality also matters for the transmission of airborne infections, such as influenza, measles, or COVID-19," Carroll says. "Indoor Air Quality (IAQ) affects everyone, especially the most vulnerable—children, the elderly, and people with health conditions like asthma and heart disease. When it comes to air purifiers, there are one or two certifications we always like to see, depending on whether the purifier uses a filtration system or UV light. When set to smart mode, the air purifier will automatically change its settings to best suit the room's air quality and lighting conditions. You can also set a timer, change the fan speed, and easily see when the device needs a filter replacement.

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. Once you’ve established your purifier includes all the necessary qualifications you need to make it effective, it’s time to think about more cosmetic and practical features. 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 Rabbit Air2 purifier has five filters, including a HEPA filter to remove 99.9% of particles 0.3 microns in size, an activated carbon filter for trapping airborne chemicals and household allergens, and a customizable filter. In addition to the pet allergies filter you can also choose filters for germs, odors, and toxins. It’s designed to work in spaces up to 1070 square feet, making it versatile enough to work efficiently in most bedrooms, living rooms, and home offices. 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). You may also want to consider purchasing an air quality monitor in addition to an air purifier so you can make sure your air purifier isn't working too much or too little in your space. Dust, pollen, smoke removal is how well a model cleared air of fine clay dust and cigarette smoke when operating at a low speed that was typically one setting above the lowest speed. Many models have multiple speeds and the lowest is not as effective at cleaning the air. A model that scores well for dust removal should perform comparably for pollen.
