Exact variant	US 5510, the closest current model to the discontinued 5500-2	HealthMate standard model
Dimensions	13.59 × 8.27 × 22.17 in (width × depth × height). It weighs 13.3 lb. The 5500-2 was wider, taller and heavier, at 15 × 8.2 × 23.6 in and 15 lb.	14.5 L × 14.5 W × 23 H in; 47 lb.
Installation	No installation. It plugs into a standard 120 V, 60 Hz outlet. Winix's manual says to leave 12 to 18 in from walls, and never less than 12 in while it runs. Leave the same gap from TVs, radios and other electronics. Use it indoors on a hard, flat surface, out of direct sunlight.	No installation. It plugs into a standard 120 V outlet. Austin Air says to set it on a flat, dry, stable surface at least four inches from any wall, with the vent facing away from the wall. It's meant to run 24/7.
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.	Steel housing with a 360° perforated intake and a baked-on powder-coat finish. The filter has a large-particle pre-filter, a medium-particle pre-filter, over 780 cubic inches of activated carbon and zeolite (up to 15 lb), and 60 sq ft of HEPA media.
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.	Five years on the unit against defects in material and workmanship, under normal home use. Coverage depends on returning the warranty registration. The filter has its own five-year pro-rated warranty, and Austin Air doesn't explain how the pro-rating works.
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.	30-day money-back guarantee, no questions asked. Austin Air doesn't say who pays return shipping.
Unresolved questions	Power draw at each fan speed and on standby, and which speed the 65 W rating refers to Noise on Low, Medium, High and Turbo Whether AHAM's directory lists the 5510 at Winix's CADR figures. The directory couldn't be read Whether CARB certified the 5510 or 5520. The readable part of CARB's list showed only the 5530 Whether PlasmaWave is on when you first switch the 5510 on. The 5500-2 manual says it was Whether there's any timer without the app Shipping cost from Winix's store How long the $199.99 and $49.99 sale prices last How the 5510 does in independent testing	CADR for smoke, dust and pollen, and the room size it suits Power draw at each speed, so running cost is unknown Noise at each speed How the pro-rated filter warranty is calculated Why Austin Air's two stores list different prices Whether it's in AHAM's Verifide directory or on CARB's certified list
