Frequently Asked Questions

Common questions about this comparison

Which is better for pet owners?

Both are effective. The Winix 5520 explicitly targets pet allergies and has a robust activated carbon filter system. The Coway AP-1512HH also effectively reduces odors and allergens with its True HEPA and activated carbon pre-filter, making both strong contenders for pet owners.

What's the main difference in coverage?

The Winix 5520 has a slightly larger AHAM-verified coverage of 391.67 sq ft compared to the Coway AP-1512HH's 375.0 sq ft. This means the Winix can purify a marginally larger room more efficiently.

Is the price difference worth it?

The Winix 5520 is $25 more. It offers slightly higher CADR and coverage, plus a washable pre-filter that can save costs on replacements. If these marginal improvements and features like pet allergy targeting are important, the extra cost may be justified.

What about ozone generation?

The Winix 5520's PlasmaWave feature may generate trace amounts of ozone. The Coway AP-1512HH does not use a similar ionizer technology, making it a preferable choice for those concerned about any ozone production.
