Winix C535 Air Purifier

The problem

A single cat or dog can spread dander — microscopic skin flakes — throughout a room within hours of grooming or moving around. For allergy sufferers or anyone who notices persistent pet odour, a standard air freshener masks the problem without removing the particles. Dander stays airborne for hours; simply opening a window moves it around rather than removing it.

What tends to help

The Winix C535 combines a true HEPA filter (rated to capture 99.97% of particles 0.3 microns and larger) with a carbon filter for odour. It covers up to 50 square metres — enough for most living rooms plus a hallway. A PlasmaWave feature breaks down airborne contaminants at a molecular level.

A straight answer: Filter replacements cost around £30–40 per year. The PlasmaWave feature produces trace ozone — most owners run it with PlasmaWave off as a precaution around pets.

Common questions

Is the Winix C535 better than the Levoit Core 300 for pet owners?

For larger rooms, yes. The Winix covers roughly twice the floor area and adds a carbon filter for odour. The Levoit Core 300 is a better choice for a bedroom or small flat where a full-sized unit is not needed.

Should I run PlasmaWave around my pets?

Most owners turn PlasmaWave off as a precaution. It produces trace ozone, which at the levels this unit generates is unlikely to cause harm but is an unnecessary variable with pets in the room. The HEPA and carbon filters work without it.
