A Brief Comparison Table

My Experience With Winix 5500-2 Vs. C545

Moving into my 800-square-foot home in January 2025 with Max and my seasonal allergies, I needed an air purifier to tackle dust and pollen. I started with the Winix 5500-2, grabbing it for $160 on February 10. Setting it up on February 12 took 25 minutes, and its 360-degree intake kicked in fast, clearing my living room air by March 1.

 The 28 dB hum on low was soothing, but it jumped to 58 dB on high during a smoky cooking session on April 5. By June 1, after 60 hours, the pellet carbon filter still smelled fresh.

On May 5, I snagged a refurbished Winix C545 for $150, intrigued by its Wi-Fi. Installation on May 7 took 20 minutes, and the app connected on May 10, letting me monitor air quality from my phone—a game-changer during a dusty clean-up on June 15.

 The 28 dB low setting on May 20 lulled me to sleep, though high speed hit 58 dB on June 10. After 50 hours by June 25, the sheet carbon filter held up, but the app lagged once on June 22. With 110 hours logged across both, let’s find your perfect match!
