Frequently Asked Questions
Common questions about this comparison
Which air purifier is better for pet owners concerned about odors?
The Winix 5520 is superior for pet owners due to its high deodorization carbon filter, which actively reduces pet odors and VOCs. Both capture pet dander with True HEPA and similar CADR smoke ratings.
What's the key difference in their filtration systems?
Both utilize True HEPA filters for fine particles and offer similar CADR smoke (around 250). However, the Winix 5520 includes an activated carbon filter specifically for VOC and odor reduction, a feature not explicitly mentioned for the LEVOIT.
How do their room coverage claims compare?
The Winix 5520 is AHAM verified for 391.67 sq ft, indicating effective cleaning. LEVOIT's effective AHAM coverage is similar (based on CADR 250), though it markets up to 1875 sq ft for 1 air change per hour, a less stringent measure.
Is the Winix 5520's higher price justified?
The Winix 5520 is $20 more, offering explicit VOC and odor filtration through its activated carbon filter. If these concerns are paramount, the added cost is justified. LEVOIT offers competitive particle filtration and WiFi for less.
