Overview –
The WINIX 5510 is designed for floor or tabletop use in large rooms up to 392 square feet. It uses a True HEPA filter, activated carbon filtration, and PlasmaWave plasma technology as its primary air-cleaning mechanisms. It is considered the successor to the now-discontinued Winix 5500-2, trading slightly lower raw air-cleaning performance for a modern design and smart app features. Consumer ReportsPropel RC
Design & Build –
The 5510 is a tall, charcoal gray unit — about 25 inches high, 16 inches wide, and 11 inches deep. The matte dark gray color hides dust and fingerprints well. It pulls air from the front and sides, then sends cleaned air straight up, which means you can place it closer to a wall without blocking the output and avoid getting a direct cold breeze when sitting nearby. Air Purifier GURU
After reviewing newer Winix models, it’s clear that Winix is focusing heavily on aesthetics with this new generation of air purifiers. The control panel is intuitive and easy to navigate, and an LED air quality indicator changes color from blue to red depending on air quality. HouseFresh
Filtration System — 4 Stages
The WINIX 5510 features a 4-stage air purification system:
Washable Pre-Filter — your first line of defense against large airborne particles
Activated Carbon Filter — uses effective carbon pellets to remove odors, outperforming traditional carbon-coated mesh
True HEPA Filter — captures 99.99% of airborne allergens down to 0.01 microns
PlasmaWave® Technology — breaks down pollutants at the molecular level without producing harmful ozone Winix
Performance –
The Winix 5510 has a high CADR of 253 CFM (430 m³/h), covering rooms up to 392 sq. ft. In testing, it achieved a 96% improvement in air quality, placing it among the best air purifiers tested — matching the performance of the Coway AP-1512HH and Levoit Vital 200S.
Air Purifier First In real-world testing, the 5510 needed 24 minutes to achieve PM1 zero in a 728 cubic ft. test room at top speed, which is powerful enough to provide five air changes per hour in rooms up to 373 sq. ft.
Analysis of over 2,600 customer reviews reveals that 94% of users experienced significant improvements in indoor air quality, with many noting it “works better than expensive alternatives” straight out of the box, often outperforming models priced 20–30% higher. The Inside Review
Noise Levels –
At the lowest speed, the 5510 produces 40.2 dBA — quite impressive and within the range of some of the quietest air purifiers tested.
Sleep mode is incredibly quiet at just 27.8 decibels — so quiet you can’t hear it from another room. Turbo mode is louder at around 59.3 decibels, comparable to a normal conversation.
However, at its highest turbo speed, the noise is considerable — you wouldn’t want to be in the same room with it running on Turbo. A common complaint is that air cleaning performance drops significantly at quiet speeds, so the unit isn’t moving enough air for serious purification on Sleep or Low.
Smart Features & App –
The 5510 connects to a smartphone via the Winix Smart App, available on both iPhone and Android. It has a gas sensor that triggers auto mode and a light sensor that activates sleep mode when it detects darkness.
Setup for WiFi connectivity takes about 3 minutes, with no repeated setup attempts needed. The app works reliably and has a clean user experience, though it is more bare-bones compared to apps from Levoit and Xiaomi.
The unit also supports wireless smartphone control, has a filter-life indicator and a dirt sensor, and comes with 5 fan speeds plus auto mode.
Running Costs –
At its top speed, the 5510 draws 53.84 watts. Running it 24/7 would cost approximately $61.21 in energy costs per year. Filter replacements are recommended every 12 months, with an OEM filter set priced at $79.99 — so expect around $80 per year on filters.
Total running costs come to approximately $8 per month, including filter replacements and electricity, making it competitive for a mid-range purifier.
Who Should Buy It? –
The Winix 5510 is ideal for first-time air purifier buyers. Pet owners will love it — the washable pre-filter catches fur before it clogs the HEPA filter, and the carbon filter handles odors that pets bring into the home. Allergy sufferers will also notice relief, as True HEPA filtration combined with decent CADR ratings pulls pollen, dust, and dander from the air efficiently.
It is particularly recommended for those who want a mid-range air purifier with smart features, effective filtration, and an app that works without annoying ads.

Final Verdict –
The Winix 5510 is an outstanding air purifier — one that delivers exceptional performance, low maintenance costs, smart features, and a modern design. Based on its engineering data and overall feature set, it deserves a 4.5 out of 5. Its standout feature is the comprehensive four-stage True HEPA filtration combined with smart sensors and auto fan adjustments. Its main area for improvement is the lack of a physical remote control and an eco mode.
