Expert recommendations for the best air purifiers for your home
Indoor air quality plays an important role in long-term health. At Lightwork we've partnered with Atria to evaluate the major purifiers on the market and determine which suit different needs for different spaces. Our recommendations are driven by clinical reasoning and hard data, as well as factors such as aesthetics and volume that will make you more likely to keep these tools in your home. Some of the top factors we evaluate include:
- Throughput: Past a certain quality of filter, what matters more than anything else is how much air it moves.
- Volume: Results are limited by default to purifiers that deliver enough clean air at less than 41 decibels* (note: this typically means larger units).
- Maintenance: Results are limited by default to those with 12 month or longer filter replacement lifespans, making them easier to maintain.
- Aesthetics: Results are limited by default to models with an elevated design that can blend in more naturally to your home (the only subjective data in the algorithm).

* Quiet CADR is estimated by identifying each purifier's highest fan speed at or below 41 dBA, then deriving airflow at that speed using fan affinity laws. Products whose lowest speed exceeds 41 dBA are excluded entirely. For multi-unit combinations, each unit must operate below a lower threshold (38 dBA for pairs, 36 dBA for triples) so that the combined noise stays under 41 dBA. Full methodology
