It sits on the floor and plugs into a standard 120 V outlet. The manual asks for at least 20 cm (about 8 in) from walls and other objects. Leave 30 to 60 cm of open space above it. Keep it 2 m from a TV or other electronics, off sloped surfaces and out of direct sunlight. It's meant for indoor household use. |
| Materials | Four stages: a washable fine mesh pre-filter, an AOC carbon filter made of carbon pellets, a True HEPA filter and PlasmaWave. Winix says the HEPA filter was tested to IEST-RP-CC0007. The manual says the carbon filter can't be washed. Housing materials aren't stated. It's made in Korea. | Four stages: a washable pre-filter, a deodorization filter, a HEPA filter and a bipolar device. The manual calls that last stage the ionizer and gives it its own on/off button. The filter set page describes the deodorization filters as carbon filters for odors and gases. |
| Warranty | Winix gives the 5510 and 5520 a 2-year limited warranty, valid only in the US and Canada. If a part is defective, Winix will repair or replace the part or the unit. You need proof of purchase from an authorized retailer. Independent sellers on Amazon, eBay and similar sites don't count. Non-Winix filters void it, and the filters themselves aren't covered. Claims start with a form in your winixamerica.com account, and you may pay for spare parts or shipping. The manual lists repair services as not available and says no spare parts will be made after the warranty ends. The discontinued 5500-2 is still on Winix's 2-year list. | Coway's manual covers the motor and electronic parts for 3 years from the original retail purchase. Internal and functional parts get 1 year. Coway's support list also puts the AP-1512HH under 3-year coverage. Claims need proof of purchase and a video of the problem. Filters aren't listed as covered. Problems caused by non-genuine filters, skipped filter changes, or commercial or office use are excluded. |
| Returns | Orders from winixamerica.com can be returned within 30 days of purchase. Returns must be in the original packaging with all filters, manuals and parts. You pay the return shipping, and Winix asks you to mark the return authorization number on the box. If you bought from another retailer, its policy applies. Restocking fees aren't mentioned. | The product page offers a 30-day money-back guarantee and "30 days free return", with an asterisk pointing to the return policy. That policy gives you 30 days from the ship date to request a return. It also says you pay shipping, handling and processing costs unless Coway made the error. If parts are missing, Coway may charge a restocking fee of 15% of the price or the value of the missing parts, whichever is higher. Refunds go to the original payment method. The policy doesn't say whether opened filters can be returned. |
