We think that the IQAir Health Pro Plus is a standout option among home air purifiers, offering exceptional performance in our comprehensive tests. This model, known for its extensive carbon filtration, effectively handles a variety of air quality challenges. It excels in both large residential and commercial spaces, providing up to 1125 square feet of coverage. With its triple-layer filtration system, including a pre-filter, V5 cell, and HyperHEPA filter, the Health Pro Plus captures ultrafine particles far smaller than standard HEPA filters can manage.

Coway Airmega 400
Vacuum Wars Stars 3.59
The Airmega 400 is designed for large spaces. Coway describes this in a couple of ways. Suggested coverage is 1,560 sq.ft. In rooms of that size the 400 is capable of doing two full air changes per hour. If compared with an air purifier citing one ACH (air change per hour) that number doubles to 3,120 sq.ft. Coway seems to have arrived at a good balance of features, performance and price with the Airmega 400, and we think it’s definitely worth consideration when shopping in this price range.

How to select the best air purifier
Air purifier basics
Almost all air purifiers have a HEPA filter connected to a fan, which processes the dirty air through the HEPA filter. This catches most of the small particles people want to filter out.
But, HEPA filters cannot filter smoke or gases. For that, you need some kind of carbon filter, which often takes the form of a filter with small charcoal pieces that absorb smoke and gases.
Adding a good carbon filter can be pricey, so you typically only find really good smoke and odor reduction with more expensive air purifiers.
How we test air purifiers
Here’s some of what goes into selecting our picks for the best air purifiers.
Airflow and noise
RELATED: See our comparison of the Levoit Core 300 and a best-selling GermGuardian model.
Filtration and VOC tests
Additionally, we do a VOC smoke test by releasing exact amounts of incense smoke into a sealed refrigerator and measuring the reduction of smoke and other volatile organic compounds in a 5-minute test on max power. This effectively tests the efficiency of their carbon filters.

Features and cost of ownership
For instance, some models have built-in particle sensors to adjust the fan speed based on the air’s dirtiness, while others have lights that change color according to air quality.
Some of the features incorporated into our Best Air Purifier scoring algorithm:
- Auto Mode
- Power Levels
- Sleep Mode
- Timer
- Ozone Filter
- UV Purification
- HEPA Filtration
- Photocatalytic Ionization
- Wifi / App (Smart Features)
- Remote Control
- Air Quality Indicator
- PM2.5 Particle Sensor
- Alexa Compatibility
- Google Home Compatibilty
- Oscillation
- Formaldehyde Detection
- No2 Detection
- Aroma Therapy
Some even have real-time graphs on their displays showing alerts and levels. We factor in the cost of replacing filters, cord length, warranty length, and compile all this information into a spreadsheet, which then helps us determine the best options according to our algorithm.
So when choosing an air purifier, consider these essential factors:
- Airflow and Power Settings: Check how fast the purifier can process air on various settings.
- Noise Level: Quieter models are generally more comfortable for continuous use, especially in living or sleeping areas.
- Efficiency Tests: Look for models that have been tested for their ability to reduce particles in the room quickly. Particle counters and VOC smoke tests can be particularly revealing.
- Special Features: Some purifiers come with built-in particle sensors, air quality lights, heaters, or even fans. These additional features can enhance usability and effectiveness.
- Maintenance Costs: Consider the cost of replacing filters and other maintenance requirements.
- Warranty and Build Quality: A longer warranty can indicate better build quality and manufacturer confidence in their product.
Making the right choice
- For smaller spaces or budget constraints, a basic model with good particle filtration might be sufficient.
- If you need effective smoke and odor reduction, consider models with high-quality carbon filters.
- For the best overall performance, look for a model that balances top-notch filtration with useful features, reasonable maintenance costs, and a solid warranty.
Conclusion
Whether you’re looking for a basic unit for a small room or a more advanced model for comprehensive air cleaning, understanding these key factors will guide you to the right choice for your home or office.

Best Budget Air Purifier
In the budget category, it was almost a tie between the Levoit Core 300 and the Kenmore PM1005 (Amazon). In the end, the Levoit air purifier won out by just a few points.
Both are priced very competitively and perform exceptionally well for smaller spaces. Although they lack many advanced features and aren’t the best for smoke or odor reduction (which makes sense when you take their low price into account), they excel in particle filtration in small spaces.
The Levoit Core 300 is one of the best selling air purifier models online. It’s a trusted model that’s been around forever and it has a ton of happy customers. The Kenmore is a newer mode, but early reviews look very promising.
Tip: For those looking for smart features including the ability to control their air purifier from an app, give the Levoit Core 300S (Amazon) a look. It is a slightly more advanced version of the Core 300 model.
Best Value Air Purifier
If you need an air purifier that has good smoke and odor reduction capabilities, you should consider our next pick, the Winix 5500-2.
The Winix 5500-2 won our best value category. In many ways this Winix model is the biggest story in this competition. Despite being relatively affordable, it performed like a much more expensive air purifier.
How much more expensive? It scored eighth overall in this year’s competition, but is by far the cheapest on that top eight list.
| Air Purifier Ranking | Price |
|---|---|
| #1 | $1,099 |
| #2 | $1,369 |
| #3 | $750 |
| #4 | $899 |
| #5 | $650 |
| #6 | $769 |
| #7 | $750 |
| #8 (Winix 5500-2) | $250 |
Its high-quality carbon filter for gases and VOCs is uncommon for its price range. And, it boasts several features, such as a particle counter and air quality indicator light.
Additionally, it performed above average in our filtration tests, scoring much better than average. Winix air purifiers in general, and the 5500-2 model specifically are quite popular online. Reviews for the 5500-2 are very positive.
Best Air Purifier Overall
For the best overall air purifier of 2023 the winner was a big surprise. the Dyson Big+Quiet Formaldehyde took top honors.
Up until recently, the IQAir GC MultiGas and IQAir HealthPro Plus had dominated our tests. And, if you had asked us a few weeks ago, we would have told you that no air purifier would beat those IQAir models in the premium air purifier category.
However, the recently released Dyson Big+Quiet model changed the game. Though the IQAir units still slightly outperformed the Dyson in filtration, the Dyson Big+Quiet Formaldehyde had impressive features that boosted its overall score.
The Dyson actually received our best scores ever in the features category. In contrast, the IQAir models were the two worst scoring air purifiers in this year’s competition.
This competition was close in many ways. For example, the Dyson Big+Quiet was basically tied with the IQAir HealthPro Plus in our TVOC smoke tests and it was pretty close to them IQAir models in our particle test, too.
From a real-time particle display, VOC display, nitrogen, and formaldehyde sensors, to an app with data history, adjustable fan, lower filter replacement costs, and a modern design, it was the clear winner.
Downsides? The Dyson Big+Quiet is not only Dyson’s most advanced air purifier, it’s also their most expensive.
Best Air Purifiers for 2023
To summarize, for our budget pick, either the Kenmore or the Levoit Core 300 would suffice. The Winix 5500-2 is the best value, and the Dyson Big+Quiet Formaldehyde is our top pick for best overall in 2023.

Frequently asked questions
What is the best air purifier right now?
Our Best Overall pick carries the badge at the top of this page, and the same purifier holds rank #1 in the ranking below it. The ranking is continuous, so the top spot changes whenever our testing says it should.
How do you decide the rankings?
Each model goes through the same test process. We measure airflow on each power setting and the noise level, run a fog test that tracks how quickly the purifier reduces particles in a ventless room on max power, and run a VOC smoke test in a sealed refrigerator to test the carbon filter. We also score special features, filter replacement cost, cord length, and warranty length. Because our protocol never changes, the scores you see reflect genuine performance differences rather than shifting benchmarks.
How often is this page updated?
Air purifier models and availability can change over time. We track new releases, product updates, and price changes, updating our rankings on a regular basis to reflect the latest information. Each review and best-list entry includes a clear “last updated” date so you know when its details were last verified.
Do you buy the air purifiers you test?
Vacuum Wars is funded through reader support and affiliate commissions. We do not accept payments, free products, or sponsorships from manufacturers. That means our air purifier reviews and best-of lists are driven solely by our independent testing and objective data.
