Our Verdict

The Winix 5510 is the next generation of the popular 5500-2, now with WiFi app support for remote control and scheduling. Its washable pre-filter catches pet hair and large particles before they reach the True HEPA filter, extending its lifespan significantly. The washable AOC (Advanced Odor Control) carbon filter is particularly effective at neutralizing pet odor — more so than many competitors with disposable carbon layers. PlasmaWave technology adds a secondary filtration stage that breaks down allergens at a molecular level without producing harmful ozone. With 1,881 sq ft of coverage, it now rivals the Levoit for room size.

Pros & Cons

Washable pre-filter saves money and extends HEPA life
Best odor control in this lineup — washable AOC carbon filter
PlasmaWave adds molecular-level allergen breakdown
Low annual filter replacement cost

Cons

Newer model with less long-term track record than the 5500-2
Louder than Levoit at higher fan speeds
App experience not as polished as Levoit VeSync
