Independent research ยท Based on Winix's official maintenance guidance ยท Updated August 2026
The Winix 5500-2 is a favorite for one reason: near-top-tier cleaning at a mid-range price. But its filter system has three separate layers with three different schedules, and owners regularly overspend (or underspend) because they confuse them. Here's the exact schedule, 2026 prices, and the reset procedure.
Three layers: washable fine pre-filter (rinse every 2-4 weeks), carbon pre-filter part 114090 (~every 3 months), and genuine True HEPA Filter H part 116130 (~every 12 months).
Realistic genuine yearly cost: $50-$65. The check light resets by holding the reset button 3-5 seconds after a HEPA swap.
| Layer | What It Captures | Interval | Approx. Cost |
|---|---|---|---|
| Fine mesh pre-filter | Pet hair, lint, large dust | Wash every 2-4 weeks, never replaced | $0 |
| Activated carbon pre-filter (114090) | Odors, VOCs, smoke smell | ~3 months | $5-$8 each (4-packs $20-$30) |
| True HEPA Filter H (116130) | Pollen, dust mites, PM2.5, dander | ~12 months | $25-$35 |
Intervals per Winix's maintenance documentation for typical use. Smoky or pet-heavy homes should halve the carbon interval.
That 3-month carbon cycle is the big difference versus rivals: the Coway AP-1512HH runs 6 months per carbon filter and the LEVOIT Core 300 uses a single 3-in-1 cartridge. We compare the total cost of ownership in our Coway vs Winix head-to-head.
Carbon swaps (every 3 months) don't need a reset โ only the HEPA cycle trips the indicator. If odors return early between swaps, that's the carbon saturating; a fresh sheet fixes it in minutes.
That keeps the 5500-2 competitive, though the carbon cycle means more frequent (if cheaper) maintenance than the Coway's twice-a-year rhythm โ a trade-off we unpack in the Coway vs Winix comparison. For general filter lifespan context across brands, see how often to change air purifier filters.
Every 12 months (genuine Filter H, part 116130). Carbon pre-filters run on a 3-month cycle; the mesh pre-filter is washable forever.
About $50-$65 with genuine parts, $30-$45 with compatible bundles.
After a HEPA swap, hold the reset button 3-5 seconds until the indicator clears.
No โ saturated carbon must be replaced. Only the fine mesh pre-filter is washable.
A fresh Filter H and carbon sheet restore the unit to its rated 246 CADR. Check today's prices on genuine and compatible sets.
