2026 verdict
Rinse a pre-filter or replace one? The Winix 5520 wins this comparison on that question and on price, adding a washable pre-filter, a certified True HEPA filter and a switchable PlasmaWave stage the Levoit Core 600S-P does not have.
The Levoit Core 600S-P answers with the higher owner rating and, on paper, a much bigger AHAM Verifide CADR: 391 CFM for 606 sq ft against the Winix 5520's 253 CFM for 392 sq ft, plus a screen, a remote, a child lock and ozone-free certification. Both share the same connectivity and smart home integrations. Pick the Winix 5520 for a large bedroom or living room on a lower budget, and the Levoit Core 600S-P for an open floor plan or a home that wants no ionizer at all.

What the differences mean
Filter stack
The Winix 5520 has a washable pre-filter, a certified True HEPA filter and a PlasmaWave ionizer stage you can switch off. The Levoit Core 600S-P has neither a washable pre-filter nor an ionizer: its H13 True HEPA and carbon sit in one cartridge, replaced whole.
Room size
The Levoit Core 600S-P is AHAM Verifide at 391 CFM for 606 sq ft, enough for an open living area. The Winix 5520 is rated at 253 CFM for 392 sq ft, sized for one large room.
Ozone-free certification
With no ionizer stage, the Levoit Core 600S-P is certified ozone-free. The Winix 5520's PlasmaWave stage keeps it off that list, even though the ionizer itself can be switched off.
Controls
The Levoit Core 600S-P has an LED screen, a physical remote and a child lock. The Winix 5520 shows readings through a colour light and the app, and whether it has a child lock is not documented.
Price
The Winix 5520 is the lower priced of the two, on top of adding the washable pre-filter.
Which one to buy if
- the room is an open floor plan
At 391 CFM for 606 sq ft, the Levoit Core 600S-P is sized for the space; the Winix 5520 is not.
- you would rather wash a pre-filter than replace a cartridge
The Winix 5520 has a washable pre-filter; on the Levoit Core 600S-P it is part of the replaceable cartridge.
- you want no ionizer in the house at all
The Levoit Core 600S-P is certified ozone-free and carries no ionizer stage.
- you like a physical remote and an on-device screen
The Levoit Core 600S-P ships with both; the Winix 5520 has neither.
- budget is the deciding factor for a single large room
The Winix 5520 costs less and its 392 sq ft rating still covers a big bedroom or living room.

What owners say
Levoit Core 600S-P owners are won over mostly by odor removal: cigarette and shisha smell fading within minutes once the sensor kicks the fan up, cooking and litter box smells disappearing before they spread through the house, and one owner's smoke-soaked basement finally clearing. The PM2.5 auto mode gets credit for reacting to burnt toast or an open window on its own, and the VeSync app earns praise for quick scheduling and air quality alerts, with easy Alexa and Google Home linking. The complaints run the other way: only the lowest speed or two are quiet enough for a bedroom, the filter is a real running cost at about 8 months with no washable pre-filter, and a few owners report a plastic smell at low speed or a sensor that never reacted.
