Nimbair makes True HEPA H13 air purifiers and replacement filters for every space in your home — from desks and bedrooms to whole open floors. Every unit captures 99.97% of airborne particles down to 0.3 microns (dust, pollen, pet dander) and uses an activated-carbon layer to take on smoke and everyday odors, so your air doesn't just smell cleaner — it is cleaner. Quiet, automatic, and built to run all day.

Place your purifier in the room where you spend the most time, a few inches from walls and furniture so air can flow freely. Plug it in, press power, and leave it on auto — the built-in sensor adjusts the fan for you. Use sleep mode at night for quiet operation, and replace the filter when the change indicator lights up. No app or setup required.

What does a Nimbair purifier capture?

The True HEPA H13 filter captures 99.97% of fine airborne particles down to 0.3 microns — dust, pollen, and pet dander — while the activated-carbon layer absorbs cooking smoke and everyday odors.

Are they quiet?

Yes. On sleep mode our purifiers run at a whisper, quiet enough for bedrooms and nurseries. On auto, the fan only ramps up when your air needs it.

How often do I replace the filter?

For most homes, every few months — sooner in homes with pets, smoke, or heavy dust. Your purifier's filter-change indicator tells you when, and you can subscribe to replacement filters so a fresh one arrives automatically.

Can I leave it running all day?

Yes — Nimbair purifiers are designed for continuous use. Auto mode keeps both noise and energy use low by only working as hard as your air requires.

Do you offer replacement filters?

Yes — every purifier has a matching genuine replacement filter, available on its own or through a subscribe-and-save plan that delivers automatically so you never run on a clogged filter.
