With all the marketing hype that gets pushed into the nether it can be difficult to make an informed decision about the  best air purifier for allergies and dust. There’s a lot of ins and outs when it comes to air purification, but we’ve got you covered. To find the best air purifier for eliminating airborne particles, allergens, pet dander, mold spores, and dust from the air, we first researched units online with features like HEPA filters, UV lights and quiet operation, as well as high customer sentiment from people who have actually used the purifiers.

After finding the best models available, we purchased the top 10 air purifiers to test them out in our own living spaces and offices. As soon as we plugged the purifiers in, we tested ease of use, clean air delivery, and overall design quality. As the air purifiers did their job, we also measured how loud they were and how effectively they cleaned the air around us. With these things in mind, it was easy to choose the Germ Guardian AC4825 to become our top pick. This is an AHAM verified product with a UV-C sanitizer and True HEPA filter that cleaned even the toughest molecules out of the air.

 #2  LEVOIT LV-H132


WHY WE LIKE IT: Sometimes the best products come in small packages, and the Levoit LV-H132 air purifier fits that idea. It’s the smallest purifier on our list, but it can easily tackle poor air quality. This is why it is our honorable mention pick and could have easily been #1. It is also the best portable air purifier.

[su_column size=”1/2″][su_box title=”Pros” box_color=”#4DB227″ radius=”0″]

  • Only works in small spaces
  • No automatic shut off timers
  • Doesn’t notify you when filters need to be replaced

[/su_list][/su_box][/su_column]
[/su_row]

The Levoit LV-H132 is one of the most eye-catching air purifiers on our list and the overall quality of the unit matches that same attention to detail. We were super impressed with how high-end and sturdy the Levoit felt during our testing. It’s also super compact so you can take it to any room in the house. However, you should be aware that the purifier’s small size can only effectively clean the air in rooms up to 86 square feet but it will clean the air once every 30 minutes.

The Levoit doesn’t just offer a pretty package, though. It also excels when it comes to performance, even despite its extra-small size. One of the most impressive features is its three-stage filtration system. First, your air passes through a fine preliminary filter before going through a True HEPA filter and finally through an activated carbon filter. This comprehensive approach to filtration cuts away smoke, dust, allergens and other contaminants with ease. If you’re looking for an ultra-portable air purifier that doesn’t skimp on purification power, then the Levoit LV-H132 should be a top contender.

Not many people think much about design aesthetic when purchasing a new air purifier, but this might change when you see the Swedish-made Blue Pure 211+. It nails the design aesthetic to the point that you could easily include it as a visible piece of any room in which you place it. The fabric pre-filter even comes in different colors so you can personalize the purifier even further. And the Blue Pure isn’t just built to look pretty. It features a solid and durable design that will last a long time in your living space.

One of the best things the Blue Pure 211+ offers is the sheer amount of power it can output. Able to purify the air in rooms up to 540 square feet, this is by far the most powerful purifier on our list. Fortunately, that large size doesn’t equal a ton of noise, either. On the highest setting, the Blue Pure emits noise only as loud as a soft rainfall. Color us impressed. There are some key features that the Blue Pure 211+ is missing, most notably the lack of air sensors and automatic timers, but this ends up being more of an inconvenience than anything else. If you need powerful air purification in the large spaces in your home, the Blue Pure 211+ is the air purifier for you. You may also want to read about the best air purifier for asthma.

Where most air filters only feature a single-direction air intake, the MOOKA offers a unique 360-degree air intake. This means that it’s constantly sucking air in from all around the unit, providing a much more effective clean than what many other purifiers can provide. This, along with the unit’s compact size, also make it the perfect choice for people who want to purify the air around their desk in the office.

It’s also great for office use because of it’s quiet and easy operation. The MOOKA air purifier features a single button on top of the unit that you press to change modes or power on/off. When powered on, the MOOKA is quiet so as to not disturb the people around you. If you’re going to use the MOOKA for home applications, you’d do well to take into factor the fact that the LED lights on the purifier are super bright and cannot be turned off. This can disturb your sleep. We also found taht the replacement filters for the MOOKA were extra expensive. As such, we don’t recommend running it 24/7 since you’ll need to more frequently swap out filters. Also check out the best HEPA air purifier.

How We Choose an Air Purifier for Allergies and Dust

HEPA filtration had to first meet the minimum government performance standard, which requires filters to remove at least 99.97% of airborne particulate larger than 0.3 microns in diameter from the air – but that’s standard for air cleaning units. Following that basic requirement, we set our sights on machines that went above and beyond the bare minimum and looked for filters that successfully removed extra fine particles with an efficiency of 99.99%, or higher (the efficiency scale stages filters from 99.97, 99.99, 99.999, 99.9995, and finally to 99.99999%).

An air purifier’s filter is only one part of the machine, though. For a filter’s efficiency to be utilized, the air flow driven by the machine and through the filter must be acceptable. Think about it – I can buy a HEPA filter and tape it to the pedestal fan in my bedroom, but that doesn’t make the setup a high-efficiency air purifier. Airflow driven through the machine, and the mechanical filtration process designed by the manufacturer is what truly differentiates an air mover from an air purifier.

Cubic feet per minute (cfm) is relative to the filtering process and the environment your air purifier is treating. Our top three picks our weighted against each other in terms of airflow and filtration processes, and since we’ve given the gold standard to all three with respect to filtration technologies, airflow is pretty straightforward – the higher the better (just don’t go putting an air purifier in a 2,000 sq ft space if it’s designed for 500).

Why You Should Buy an Air Purifier for Allergies and Dust

Consistent behavior is what really makes a difference in the quality of our lives. For example, if you go for a run everyday your cardiovascular health is likely better than the guy that sits on the couch instead. Similarly, if you own an air purifier that cleans your air every day, you’re likely healthier than someone that doesn’t use one. Allergy sufferers across the globe can attest to the health benefits that come from normal use of an air cleaner.

Indoor air pollutants are one of the top health risks in the United States and abroad, and the use of a machine that does its job well can make a significant difference in the quality of your life. Volatile organic compounds (VOCs) are emitted as gases from a wide array of products including paints, varnishes, solvents, and many household cleaning products. If you’re an allergy sufferer, constantly struggle with congestion, irritated by mild asthma symptoms, or just want a little reassurance that the air in your home is being cleaned, take a look at our top picks and make sure you check out their specs – they’re some of the best air purifiers for allergies and dust on the market.

Key Factors

  • HEPA Grade & Surface Area: HEPA H12/H13 is the most common among the group we reviewed – we believe that this should be an absolute minimum for most in-home applications. HEPA stands for High-Efficiency Particulate Air and a HEPA filter works by forcing air through a fine mesh that traps harmful particles like dust mites, pet dander, pollen, tobacco smoke, and more. The greater the surface area available, the more pollutants the filter can adsorb, and the longer the life expectancy of the filter. All HEPA filters in our list are expected to last a minimum of three years, with some promising up to five.

    HEPA Filter Ratings
    HEPA filter classes based on efficiency
  • Activated Carbon: Carbon helps to adsorb toxic gasses, VOCs, and smoke. Multi-staged filtration processes that are used by industrial machines not only perform better, but also demonstrate that the manufacturer understands a thing or two about air purification. Trust us, it’s not uncommon to find air cleaners that move air more than they actually purify it. If you’re looking for the best air purifier for allergies and pets, look for a good combination of HEPA and activated carbon filtration.

Features

  • Mechanical Process: We like things simple, but it isn’t because we’re opposed to technology. We prefer to eliminate pollutant sources, not introduce them, so our top picks in this list are all purely mechanical in nature – air comes in, passes through physical filters, and gets pushed back out.
  • Simple Design: Focusing on products that are developed with one main goal in mind: purifying the air. While we’re not opposed to smart features and connectivity options, for this article we focused on simple mechanics and electronics. These days even the best cheap air purifier has good features.

Mistakes to Avoid

Vague statements and a lack of technical data on the manufacturers website are abundant in this industry. Far too many list HEPA filtration without filter specifications, activated carbon without details, Clean Air Distribution Rate (CADR) without clearly defining the limitations of the CADR value. Look for manufacturers that list too much data, are eager to discuss specifics, and truly care about your well being while using their machine.

Many air purifier users sleep with their machines so it’s important to consider sound levels generated by the machine you buy. That said, moving air the right way versus just pushing air around can (and does) create noise. Consider our review and others, and the quality of the machine you purchase. If it’s a little noisier than most, but performs above expectations, that’s okay. The average maximum decibel level for most air purifiers in this category is around 70 dB. To put that in to perspective, the noise from traffic while sitting in a car is around 85 dB.

What Else You Should Think About

Having the Best Air Purifier for Allergies and Dust is only the first step in leading a healthier, less polluted life. Is your cleaner the best air purifier for cat allergies, or dogs? Will it work well for cigarette smoke? What toxins should you be concerned about? For more information on indoor air pollutants check out our article on VOCs.
