Best Blueair Air Purifiers – Top Picks Based on Real Testing

Blueair, a premium air purifier brand from Sweden, has long been a leader in the industry. In recent years, its reputation has only strengthened, thanks to a series of innovative product launches and refreshed designs.

Now owned by Unilever, Blueair continues to expand its global presence, with products available in nearly every part of the world.

Since the acquisition, several changes have stood out—particularly the upgraded designs, the enhanced Blue Pure series, and the introduction of new products like the Blue Pure Fan, ComfortPure, and HealthProtect line, both of which I find especially impressive.

In this buying guide, I’ve picked the five best Blueair air purifiers currently available, based on key criteria such as price, performance, filtration quality, maintenance requirements, and energy consumption.

So, what do all Blueair air purifiers have in common? Are they really as good as they seem—and more importantly, which model is right for you?

Top 4 Best Blueair Air Purifiers

It’s not easy to narrow it down to just four air purifiers, given how many solid models Blueair offers. But despite their similarities, I’ve carefully selected the best of the best.

Whichever model you choose from this list, you’re unlikely to go wrong. Still, I encourage you to read each paragraph closely—because while all are excellent, some may suit your specific needs better than others.

Blueair 511i Max – Best Option Overall

The Blueair 511i Max is the latest release in Blueair’s Blue Pure series and is arguably the best Blueair air purifier for most people.

What I particularly like about this model is its compact size, solid CADR for the price, efficient motor, and excellent overall performance.

With a CADR of 152 CFM (258 m³/h), it effectively covers rooms up to 236 sq. ft. (22 m²), delivering an air change rate (ACH) of 4.8.

It uses a four-stage filtration system consisting of a washable pre-filter, a particle filter, a carbon filter, and an ionizer. The Blueair 511i Max is CARB-certified, safe to use, and does not produce ozone above the permitted limits.

In our performance tests, it delivered outstanding results. In a 194 sq. ft. (18 m²) room, it improved air quality by 92% in just 60 minutes while running at maximum speed.

Once again, I highly recommend the Blueair 511i Max for most users. However, if you’re looking for a model tailored to more specific needs, keep reading.

Blueair 211+ – Best Blueair For Large Rooms

The Blueair 211+ is the largest model on this list—and one of the largest air purifiers in Blueair’s lineup.

With a CADR of 350 CFM (595 m³/h), it can clean the air in a 540 sq. ft. (50 m²) room 4.8 times per hour, making it ideal for large living spaces. We’ve also compared it in our best for large rooms guide, where it ranks among the top performers.

Like all devices in the Blue Pure series, the 211+ features a minimalist design and uses four-stage filtration: a washable pre-filter, particle filter, activated carbon filter, and HEPASilent™ technology.

In our performance tests, it delivered excellent results. In a 560 sq. ft. (52 m²) room, it improved air quality by approximately 92%.

However, it underperforms in odor removal due to its fibrous carbon filter, which is less effective than pellet-based alternatives.

As with other Blueair models, the 211+ is CARB-certified and safe to use—even though it produces ozone, it remains within acceptable limits.

It’s also worth noting that the Blueair 211+ is a purely minimalistic air purifier: it doesn’t include any advanced features and isn’t compatible with Blueair’s smart app.

Overall, the Blueair 211+ is the best choice for large rooms. It excels at capturing airborne dust, pollen, mold spores, and similar particles with ease.

Blueair DustMagnet 5240i – Best for Bedrooms

The latest model I tested from Blueair is the DustMagnet 5240i. It delivered outstanding performance in all tests, is characterized by a sleek modern design, and includes unique features exclusive to this model.

Given Blueair’s reputation for innovation, that’s no surprise.

With a CADR of 137 CFM (233 m³/h), the DustMagnet 5240i is suited for rooms up to 212 sq. ft. (19.7 m²). What stands out most to me is its energy-efficient motor of just 22W.

This is the only model on the list, besides the Blueair 511i Max, that is compatible with the Blueair smart app. If smart control is important to you, that’s a key advantage.

Thanks to its quiet operation, producing just 40.1 dBA at the lowest fan speed and 52.6 dBA at its highest, the Blueair DustMagnet 5240i is an excellent option for bedrooms or similar spaces where low noise and high-performance matter.

Blueair Mini Max – Best Compact Option

The Blueair Mini Max is Blueair’s smallest air purifier to date, and one of the most compact models on the market overall.

I believe Blueair introduced this unit to compete with other mini air purifiers like the Levoit Core Mini and similar devices. It’s designed for very small spaces, up to 93 sq. ft. (9 m²), but its test results genuinely impressed me.

It uses a three-stage filtration system, consisting of a washable pre-filter, a particle filter, and a carbon filter.

Although it doesn’t include any advanced features, there’s no air quality sensor or smart app feature, it excels in what it’s built for: compact size, low energy consumption, and solid performance for its category.

I recommend the Blueair Mini Max for very small rooms or for placement on a desk, nightstand, or other tight spaces where larger air purifiers wouldn’t fit. If you’re looking for more compact units, you might also like our best small air purifiers roundup.

What Makes Blueair Air Purifiers Better Than the Competition

To be honest, Blueair is one of my favorite air purifier manufacturers. I like their simplicity, the variety of models they offer, the quality of craftsmanship, and above all, their consistently high performance.

Blueair Series

Blueair offers several distinct air purifier lines: Blue, DustMagnet, Classic, Protect, and Pro. Each series has unique features that set it apart, along with varying price points. The Blue series offers the best value, while the Pro series sits at the top end of the price spectrum.

Global Availability

One of the things I admire about Blueair is its global reach. Their products are available worldwide and backed by excellent customer support. They’re also heavily invested in innovation—frequently releasing new models that raise the bar for the entire industry.

The Blueair App

When connected to the Blueair smart app, you gain access to remote control, voice control, screen lock, and other features.

The app is available for both Android and iOS devices and enhances the usability of supported models.

Washable Pre-Filters

Blueair stands out with its washable pre-filters, especially in the Blue Pure series. These filters are not only reusable but also come in multiple colors, allowing the devices to blend into almost any environment. I believe this feature played a big role in Blueair’s popularity—combining innovation with style and practicality.

Energy Consumption

Blueair air purifiers are among the most energy-efficient on the market. Most Blue Pure models—like the Mini Max and 411 Auto—consume only 10W.

Even with lower power consumption, performance stays strong thanks to well-optimized motors. All Blueair devices are Energy Star certified, although some older models in the Classic series may consume a bit more power.

Filtration Technology

Blueair uses advanced filtration systems across its product lines. All models incorporate HEPASilent™ technology, which combines mechanical filtration with an ionizer. Importantly, Blueair devices are CARB-certified, meaning they produce ozone within safe, legal limits.

Some high-end models, such as the HealthProtect 7470i, use DualProtection filters—a combination of particle filters and sustainably sourced coconut carbon. These filters remove pollutants up to four times faster than conventional carbon filters, while also reducing noise levels for quieter operation.

Warranty

Warranty terms depend on the product line. The Blue series includes a 2-year warranty, while higher-end series like Protect and Pro offer warranties of up to 5 years—a generous and commendable policy for this type of device.

Room Coverage

Thanks to its diverse lineup, Blueair has a model for nearly every room size:

• For small spaces up to 200 sq. ft., consider the Blueair 511i Max.
• For medium-sized spaces, the Blueair DustMagnet 5240i strikes the perfect balance.
• For large rooms up to 600 sq. ft., the Blueair 211+ is the ideal choice.
