Keep Your Air Purifier Working Like New

Your air purifier is only as good as the filter inside it. Over time, a filter that's done its job fills with the dust mite allergens, pollen, mould and dust it's captured — and a clogged filter cleans less air, more slowly. This genuine 6-stage replacement set restores your iDUST Air Purifier to full performance, so it keeps capturing 99.97% of airborne allergens night after night.

➤ Genuine iDUST filter — made to fit the iDUST Anti-Dust Mite Air Purifier exactly
➤ Full 6-stage system in one cartridge — pre-filter, HEPA 13, activated carbon and photocatalysis
➤ HEPA 13 grade — captures 99.97% of dust mite allergens, pollen and mould spores
➤ Quick, tool-free swap — slides in and out in under a minute
➤ Restores airflow and efficiency — a fresh filter cleans more air, faster

What's Included

1× iDUST 6-Stage Replacement Filter Set (pre-filter + HEPA 13 + activated carbon + photocatalysis)

⌵ When Should I Replace My Filter?

For most bedrooms, every 3-6 months depending on use and air quality. Your purifier's screen will tell you when it's time. A quick test in between: if you vacuum the pre-filter and airflow still feels weaker, or odours linger longer than they used to, your filter has reached the end of its life and it's time for a fresh set.

⌵ What Each Stage Does

Pre-filter → catches hair, pet dander and large dust.
HEPA 13 filter → captures 99.97% of fine particles like dust mite allergens, pollen and mould spores.
Activated carbon → absorbs odours, cooking smells and chemicals like formaldehyde.
Photocatalysis filter → breaks down harmful compounds at a molecular level.

⌵ How To Change It

Switch the purifier off and unplug it. Open the rear or base panel, lift out the old filter cartridge, and slide the new one in the same way round. Close the panel, plug back in, and reset the filter indicator if prompted. That's it — no tools needed.

At iDustMite®, everything we do is designed for people with dust mite allergies.

Not some people. Not most people. You.

From the first design sketch to the final stitch, our dust mite pillow protectors, duvet protectors, and mattress encasements are made with one clear goal — to help dust mite allergy sufferers sleep in a cleaner, calmer bed.

Because when bedding is designed for dust mite allergies from the start, nothing important gets missed:

Precision stitching to reduce weak points where allergens can escape

Sealed zip closures for full pillow, duvet, and mattress encasement

Dust mite-proof materials designed to help keep allergens trapped inside

We openly show how our products are tested — many bedding brands do not.

Our dust mite pillow, duvet, and mattress protectors are independently tested by Shirley®, a respected UK laboratory known for textile performance and barrier testing.

Certified safe materials

All iDustMite® fabrics are OEKO-TEX® certified, meaning they are tested for harmful substances and are suitable for both adults and children, including those with sensitive skin.

Designed to block dust mites at the source

Our encasements are engineered with a ~5 micron dust mite barrier, designed to help block dust mites and their allergens from escaping the bedding — where exposure most often happens.

This focus on transparent testing, material safety, and purpose-built design is why iDustMite® is made specifically for dust mite allergy sufferers — not a one-size-fits-all bedding solution.

Eucalyptus silk naturally helps repel dust mites by reducing the warm, damp conditions they need to thrive.

It has excellent moisture-wicking and breathability, helping keep bedding drier throughout the night.

Our 1,000 thread count eucalyptus silk, woven in a tight percale weave, creates a dense fabric structure that helps block dust mites while staying smooth and gentle on sensitive skin.
