- Which is better for a bedroom?
- The Winix 5500-2. It is rated 27 dB on low and covers 360 square feet, and it costs $87.00 at its lowest recorded price. The Dyson adds a fan you likely won't need at night.
- Does the Dyson actually filter better?
- On paper, yes. Its HEPA H13 filter is EN1822 certified and captures 99.97% of particles down to 0.3 microns. The Winix uses a true HEPA filter but publishes no equivalent certification.
- Is the Dyson worth the extra money?
- Only if you want the cooling fan and oscillation. At $219.99 versus $87.00, you pay roughly $133 more for the fan, 10 speeds and the taller tower.
- Which has cheaper filter costs?
- The Winix. Its pre-filter is washable and permanent, so you replace only the HEPA and carbon filters. The Dyson has no permanent filter, so its HEPA unit is replaced outright.
- Can I control either with my phone?
- No. Neither has Wi-Fi or app control. Both include a remote, the Winix works with Alexa and Google Assistant, and the Dyson lists Alexa only.
- Which moves more air?
- The Dyson, in practice, because it doubles as a fan with 10 speeds and 350-degree oscillation. The Winix lists 760 m³/h air volume and a 246 pollen CADR.
