Winix 5510 Air Purifier Review: Would Owners Buy It Again?

Disclosure: As an Amazon Associate I earn from qualifying purchases. If you buy through links on this page we may earn a commission at no extra cost to you. How this review was made: We did not test this purifier in person. This verdict is based on two independent reviews that ran their own measurements plus a retailer-style owner summary, all listed at the end. The two reviews report different numbers (for example noise and CADR) because they used different methods. We found no multi-year durability data for the 5510, which is a newer model. Our method.

Repeat

A solid mid-size purifier that most buyers would likely repurchase

Both detailed reviews we read found the 5510 clears particles fast at top speed, runs quietly at low speeds, and uses little power. One tester rated it highly and recommended it; the other said it is worth considering but weaker than the older 5500-2 at quieter speeds. The main trade-offs are loud operation at the highest speed, smaller filters than the 5500-2, and an auto mode that senses odors rather than particles. Because the evidence is generally positive, we lean toward repeat.

Buy it again if you…

  • have a living room, kitchen or bedroom of roughly mid size
  • want app control and an easy filter-replacement indicator
  • have pets and like a washable pre-filter

Skip it if you…

  • need very quiet cleaning at high airflow
  • want cheap third-party replacement filters
  • want auto mode to react to dust or pollen

The Winix 5510 is the newer replacement for the popular 5500-2. It uses a True HEPA filter, a pellet carbon filter and a washable pre-filter, with a PlasmaWave ionizer you can switch off. It adds an app, an odor sensor with auto mode, and a more compact body.

Check that the listing you buy is the 5510 and that replacement filters match: the 5510 uses a different filter than the 5500-2.

What testers like

Fast cleaning.One tester measured particles dropping about 96 percent in an hour in a 320 sq ft room at top speed; another cleared PM1 to zero in 24 minutes in a larger room.
Quiet at low speeds, low power.Sleep and the first two speeds measured between roughly 35 and 43 dBA, with very small electricity use at those speeds.
Pet-friendly design.The washable pre-filter and modern, smaller body get praise.

What testers criticize

Loud at top speed.Both reviews note it is louder at the highest speed than some competitors.
Smaller filters, pricier refills.The filters are smaller than the 5500-2's, a replacement set costs more than one tester expected, and third-party options are limited.
Limited auto mode and app.The sensor reacts to odors rather than particles, and the app has fewer features than some rivals.
Weaker at quiet speeds than the 5500-2.HouseFresh said cleaning drops at sub-45 dBA speeds and recommended a different Winix for quiet use.

How it holds up over time

The 5510 is a recent model, and we found no long-term reliability data. The filter is rated for up to 12 months, so ongoing filter cost matters more than the machine price over the years.

Tips from reviewers

  • Run it on a middle speed for day-to-day use and save top speed for short bursts.
  • Turn PlasmaWave off if you prefer filtration only.
  • Buy the correct filter, since 5500-2 filters do not fit.
