Most people now spend more time indoors. Not that it’s a bad idea, but if one person takes 20,000 breaths per day, and you’re all cramped up in a little space, then that may result in air quality issues.

You see, there’s a good reason you would want good ventilation. As an engineer, this I know – bad air quality induces sickness, increases molds, and, overall, reduces your everyday productivity.

Can air purifiers protect you from the Coronavirus? Not directly. But a True HEPA filter running for a long time can filter a big chunk of viruses up to 99.97%. Moreover, air purifiers with UV light can disable COVID-19 viruses. Overall, an air purifier promotes a safer indoor environment.

And that’s why investing in a great air purifier should be everyone’s concern, especially if everyone’s working from home.

So what’s an ideal Air Purifier Brand to buy?

An ideal air purifier should provide a great air purification system. This means providing clean, fresh, and filtered air. An excellent air purifier removes dust, pet dander, smoke, compounds and even allergens and bacteria. Plus, it should be reasonably quiet so you can sleep peacefully at night. To top it all off, price should be affordable.

But not all brands meet these standards.

After years of experience in designing and manufacturing air purifiers, we know what’s good and what’s not. Today, we give you the best air purifier brands for 2021, reviewed, tried and tested for your convenience.

Review of the 12 ‘All-Time-Best’ Air Purifier Brands

1. IQAir

Best Medical-Grade Air Purifier Brand

If you’re looking for medical-grade, high-class air purifiers for hospitals and healthcare settings, IQAir is the most ideal choice. A Swiss-based manufacturer, IQAir is a company producing air purifiers used in isolation areas for limiting the spread of COVID-19.

IQAir designs its machines to work in high risk medical environments. These include areas with high amounts of ultrafine pathogens and other airborne particles.

It has an amazing HyperHEPA technology designed to filter out up to 0.003 microns, which is beyond the filtering capacity of other HEPA filter purifiers. This also means that the IQAir brands are expensive, yet highly powerful and effective at maintaining pathogen-free air.

What’s even more interesting is that their HealthPro product has the ability to save on energy. It only operates at 27 watts for its lowest speed delivering 300 CFM. This means it will only cost you a little to run the air purifier per day! Add to that, IQAir machines are designed specifically for sound dampening, these models operate at extremely low volume levels.

IQAir also has a variety of products such as car purifiers, desktop air purifiers and industrial air purifiers. Brands include the GC MultiGas, Atem Desk and Atem Car. These are all top-notch, high-end products which may be a little pricey in terms of upfront cost, but gives a lot of benefits and low maintenance cost.

    2. Rabbit Air

    Sleek & Effective Air Purifier Brand

    If you’re looking for a reliable air purifier brand in the midrange price, Rabbit Air is a great choice. Rabbit Air air purifier models come with smart, minimalist and sleek designs which outperforms many of its competitors in the midrange level.

    Rabbit Air’s most popular products include the MinusA2 and BioGS 2.0. These come with a 4-stage air purification system, combining HEPA filters and carbon filtration. They operate in an awesomely quiet manner and are suitable for large area ventilation.

    Unlike the IQAir brand, Rabbit Air is a popular brand for household use and the consumer-level market. It may not be as budget-priced as its Winix or Levoit competitors, but it has a larger area coverage and is packed with premium features.

    Overall, we highly recommend Rabbit Air purifiers for its performance at a reasonable cost. Plus, the company offers a 5 years warranty for their air cleaners.

      3. Winix

      Unique Air Cleaner Technology

      winix brand logo
      winix brand logo

      Winix air purifiers are an equally affordable product range like the Levoit. The company manufactures several home air purifier brands and office-use product lines. The Winix brand is a highly sought product for those who want a good quality air purifier offered under $200.

      For what it’s worth, you get to benefit from its patented Plasmawave technology, Wi-Fi capability, powerful motor, True HEPA filter, and rudimentary app.

      Plasmawave Technology is a special innovation of the company to effectively remove air pollutants, as well as return air moisture. Unlike other air purifier technologies which have ionizers that only produce negative ions, the Plasmawave technology produces both negative and positive ions.

      Where the negative ions only gather contaminants together and are weighed down in the area, the addition of the positive, + hydrogen (H+) ion reduces the concentration of pollutants and increases the air moisture.

      However, Winix air purifiers may emit a little sound of about 40 decibels, which is still quieter than your refrigerator. Another thing you may consider as a deal breaker is Winix’ air cleaner equipment has higher energy consumption than other brands.

        4. Blueair

        Authentic, World-Class Air Purifier Brand

        blueair logo

        Blueair is one of the classic air purifier brands popular in the consumer-level market. The company has been a leader in the air purifier manufacturing industry for over 20 years.

        Blueair offers a wide variety of products from small to large units at a value-cost. All of which, from its 211 model to its Pro XL, delivers high quality air purification and filtration.

        Unlike other brands, Blueair’s HepaSilent filtration technology combines electrostatic and mechanical air filtration. This arrangement allows the use of less dense HEPA filters, lowering air pressure requirement per pass while maintaining high performance. This makes its machines more efficient and allows quieter operation.

        Blueair devices also use a three-part filtration process with an activated carbon filter. Its HEPA filter can remove 99.97% of pollutants such as pollen, dust, mold and pet dander and allergens. Moreover, Blueair machines are WI-FI enabled which you can operate with your smartphone.

        Another huge plus is its high ACH (air exchanges per hour) rating, which indicates that it’s a powerful air purifier. Simply put, the ACH tells you how often the air purifier filters the room/area in one hour. The higher this rating, the better. Hence, if you have allergies or asthma, you would want to choose an air purifier with a high ACH such as Blueair’s.

          5. Honeywell

          Brand Known for Powerful Air Purifier Fan

          From air purifiers to PPE, Honeywell is a global company producing a wide variety of consumer, commercial, industrial safety and engineering products. Honeywell carries a lot of trusted brands but in this post, we will only discuss its air purifiers.

          In a nutshell, Honeywell air purifiers are high quality but will not cost you a lot. It is marketed mostly for a low-range to a mid-range price point. The company uses True HEPA filters for their air purifiers, which they have improved over succeeding models.

          Honeywell manufactures a variety of air purifier models to fit small to large rooms. However, some reviews have pointed out the lack of innovation between their AirGenius 3 HFD300, AirGenius 4 HFD310 and AirGenius 5 HFD320. The good side is, the company makes powerful equipment parts for their air purifiers.

          For example, most of its models have strong fan speeds which indicate high CADR (Clean Air Delivery Rate) rating. Simply put, the CADR determines how fast the machine can filter the air from dusts and particles.

          The downside however, is it produces audible sounds at its highest setting. This makes it a bad idea if you want to place the Honeywell air purifier in your bedroom.

            6. Alen Air

            Trusted Air Purifier Brand

            They also offer a variety of HEPA type replacement filters such as their HEPA Pure, HEPA Fresh, HEPA Silver and HEPA OdorCell. You can find unique benefits for each type of filter.

            For example, their HEPA-Silver specifically addresses allergies, asthma and an added protection from bacteria. On the other hand, if you want a lower end HEPA filter, you can choose the HEPA-Pure.

            Allenair air purifiers are best for its quiet operation, high performance capabilities, smart design and wide variety of products.
